Binance – Bitcoin Cryptocurrency Exchange BNB ICO Token Sale?

This Sub Has Gotten Very Quiet

This is the problem with the crypto community. Many only get excited and interested when they see a major pump. OXTBETS seemed very active and interest peaked in late August. Then, the terrible month of September ensued (which I predicted btw, not to toot my own horn) and now Orchid's level of interest is back to the days of June and July. In the terrible words of scholarly rapper, Future: "Molly, Percocets, Rep the set, Gotta rep the set, Chase a check, Never chase a bitch." NEVER CHASE A CRYPTO or you will be doomed. (Btw Future was basically advertising street drugs which makes that a terrible song).
Everyone should watch this video by Tommy World Power: (0:48) "imagining if someone put $100 in cryptocurrency or BTC in 2009, that in 2013, that $100 would become worth $100 million. Thinking about how people go to work everyday and they have these routines...and if they could put just $100 which is possible for most people in the Western world..." I can admit that I was sleeping on crypto throughout this decade. I first heard about Bitcoin in 2013 and dismissed it as some illegal black market money laundering scheme. And in a way with Mt. Gox, it was like that. Then came the more traditional exchanges like Binance and Coinbase which helped legitimize this asset class.
(1:37) "I watched Bitcoin go from $10 to $1000 in 2013." Didn't we all? (1:50) "I actually made first major investments in Bitcoin and cryptocurrency at the end of 2013, at the end of that bubble...that next year is something we NEVER saw in cryptocurrency before.... My losses on some of them were 90%... Accumulate as much possible at those lows because I knew at some point, it would rebound." Basically, he was referring to how everyone forgot about crypto in 2015 including all his friends and how it came roaring back to reward the loyal crypto holders. Don't chase crypto gains but don't also sleep on crypto.

AMA Recap of CEO and Co-founder of Chromia, Henrik Hjelte in the @binancenigeria Telegram group on 03/05/2020.

Moh (Binance Angel)🇳🇬,
Please join me to welcome, “CHROMIA CEO & Co-founder, Henrik Hjelte” and “ CMO, Serge lubkin”
Oh, before we proceed, kindly introduce yourselves and tell us a bit about your roles at Chromia u/sergelubkin & u/henrik_hjelte.
Henrik Hjelte,
Ok, I’m Henrik, I’m CEO of ChromaWay that crated the Chromia project. My background is a bit mixed: developer for 30+ years (since 80: s), but I studied other things at university (economics, politics, social sciences philosophy). Life is more than computer you know… I worked with FInance/IT then started a web startup and got to know Alex Mizrahi who worked as a developer….
Web startup didn’t fly, but Alex showed me bitcoin. When I finally read the whitepaper I was blown away, and joined Alex colored-coins project, the first open source protocol to issue tokens. in 2013.
So, we started with open-source tokens (that kickstarted the blockchain industry. Then started company together 2014.
That is a long intro, I’ll shut up now… Thanks….
Serge,
I’m Serge, I’m assisting Henrik today and I work with Chromia marketing team as well as on some business development projects
Moh (Binance Angel)🇳🇬, , Question No 1 :
Kindly describe the CHROMIA project and what it aims to achieve?
Henrik Hjelte,
Chromia is a new public blockchain based on the idea of integrating traditional databases, Relational databases with blockchain security. Chromia is a general purpose blockchain with full smart contract capabilities, just that it is a lot easier to code, even complex applications. You code with an easy to learn new programming language that combines the power of SQL and normal languages but makes it secure in a blockchain context. Up to 1/10 the code-lines vs other blockchains. There is a blog post about it, I’ll share later. On lines of code.
The aim of Chromia is to combine relational databases, which exist in every kind of organization, together using blockchains. We want to provide a platform for our users to develop totally decentralized apps securely. Our goal is for Chromia to be seen as the number one infrastructure for decentralized applications.
https://blog.chromia.com/reasons-for-rell-compactness/
Moh (Binance Angel)🇳🇬,Question No 2:
What inspired the CHROMIA Core team to pick interest in CHROMIA project? what breakthrough have you achieved so far? what are the present challenges you’re facing and how are you planning to overcome them?
Henrik Hjelte,
We started with public blockchains, tokens in 2012, the world’s first stable coin with a bank 2015 (LHV). When coding that solution, peer to peer payments of Euro-tokens, we discovered we need performance reasons to store all data in a database. We needed to quickly know the “balance” of a user, and can’t loop through a blockchain. And slowly the idea grew that we can make the database INTO a blockchain, integrate completely with the transaction mechanism of a database. So, we did it as a private blockchain first (Postchain), used it for some projects, then came up with the idea to make a Public Blockchain based on it.
The motivation is that we felt we needed a better programming model for blockchains. Our CTO Alex has always been thinking of optimal solutions for blockchain technology and has lots of experiences thinking about it. Also: make real-world useful things. For example, we support free-to-play models since users do not need to own “our” token to USE apps, the application itself (often the developer) pays for hosting. And of course, great performance. Also: more knowledge of who runs nodes and risk level. So, it is more suitable for enterprises.
In Chromia the application (at the start the developer) decides Who should be allowed to run its own blockchain (every dapp has its own blockchain). You can also say on a higher level that we want to provide technology to create “Public applications”, a tool
that enables us to create a fairer world.
https://blog.chromia.com/towards-publicly-hosted-applications/
Moh (Binance Angel)🇳🇬, Question No 3 :
Why did you create your own blockchain instead of leveraging on existing and proven base layer protocol?
Henrik Hjelte,
None of the existing protocols are suitable to support large-scale, mainstream applications. We designed Chromia to give our users exactly what they want; fast support, useful features, with an affordable service cost. Other platforms do not have the ability to host data applications in a decentralized and secure way, as Chromia can. Chromia also has its own bespoke programming language that sets it apart from SQL-based platforms. It’s so easy to use, even non-developers can understand it!
The other big difference with Chromia concerns payments. Chromia gives its users freedom from having to pay for each transaction. With Chromia, you have the flexibility to decide how to set fees for your dapp
And when it comes to “proven base layer protocols”: they are just a few years at max. Chromia is built on top of Postgresql, that has been used in enterprises for decades, a really proven technology. And the Java virtual machine on top of that. This is proven tech, at core.
Moh (Binance Angel)🇳🇬, Question No 4 :
What is Postchain?
Henrik Hjelte,
Postchain is an open-source product of ChromaWay for enterprise clients and it’s the core technology on which Chromia is built.
Postchain is a replicated blockchain and database that offers highly resilient distributed database management with distributed control.
Postchain is the only product on the market that combines the immutable consensus of a blockchain and the properties of a real database management system (You know, the tech that built SAP, Facebook, Banks…) …
Postchain allows you to share information between companies and/or individuals in a secure and transparent way.
That is the low-level base of Chromia you can say
Moh (Binance Angel)🇳🇬,
Can you please name some of your clients that are using this service already?
Serge,
You mean products built on Postchain? Also, Stockholm Green Digital Finance, Green Assets Wallet that’s now functioning on Chromia Bootstrap Mainnet.
Big financial institutions
It’s only a beginning of course, but very promising one. https://greenassetswallet.org/news/2019/12/12/launch-of-the-green-assets-wallet
Henrik Hjelte,
We got a lot of attention with the Swedish Land registry; we did a joint project between them and banks and a telco etc on postchain as base.
Then, right now we do a large project with the Inter-American Development bank also about land-registration (processes) in South America.
We had a client, Stockholm Green Digital Finance, that did a system for green bonds (tracking environmental impact. Yes, as Sege says, it was later moved to Chromia…
Which is cool. Also, another external development company did that phase of the project, proving that other can build on our tech,4irelabs from Ukraine is their name. Some companies using the GAW: Blackrock. SEB Bank etc…
Also, we have done more projects, in Australia, asia etc. Oh Daimler too (the Mercedes company) …
Moh (Binance Angel)🇳🇬,
Lots of enterprise clients you’ve got. No wonder I do see the meme “CHR=ETH KILLER”
Serge,
It’s a meme from our supporters. But we believe we can coexist:)
For some niche things eth is good :)
So, no killing :D
Henrik Hjelte,
We want to work with partners too for this, we can’t do all projects ourselves. Also, for Chromia projects, ChromaWay company can help do support maintenance etc. So, it is not competing, it adds value to the ecosystem.
Yeah ETH is good too, for some applications. We are friends with them from colored-coin times.
And colored-coins inspired ETH, and ETH inspires us.
Moh (Binance Angel)🇳🇬, Question No 5 :
Lastly, CHROMIA is already doing very well in terms of business. You just got listed on BINANCE JEX, you are on-boarding new clients and dishing out new features. But what’s next? Is there anything to be excited about?
Henrik Hjelte,
Plans for 2020 are to both release a series of dapps to showcase how fantastic Chromia is, as well as continue to develop the platform. And when it is secure and good enough, we will release the mainnet.
Dapps are now being made by us as well as others. We do a decentralized social network framework called Chromunity, now released to TestNet. It is really cool, users can vote over moderators, and in the future users might even govern the complete application, how it can be updated. This is a great showcase for Chromia and why we use the slogan Power to the Public.
https://testnet.chromunity.com/
Games coming are:
Mines of Dalarnia (by Workinman Interactive). An action game in a mine with blockchain rental of plots and stuff. Already on TestNet and you can take a peek on it at https://www.minesofdalarnia.com
more coming…
Krystopia 2, novas journey. A puzzle game done by Antler Interactive. Could only find trailer though: https://www.youtube.com/watch?v=-G95-Dw3kI4
However, we have even larger ambitions with blockchain gaming…
We are doing A secret demo-project that we do together with Antler to showcase the technical potential of Chromia platform.
Another exciting relase is an indie game Chain of Alliance, done by two external developers. It is a strategy game with full-logic on blockchain. Public release on TestNet on May 22!
More coming in 2020: Other dapps from other companies, one in impact-tech.
That is a serious app, Chromia also works outside gaming and social media for enterprises and startups
And I hope some of you will do something, we want to support dapps on the platform so reach out to us…
Moh (Binance Angel)🇳🇬,
When can we be expecting the mainnet? Any approximate time? I’m sure the community will really excited to have that info
Serge,
It’s now in Bootstap phase, so it’s technically already functioning. MVP will be very soon
Stay tuned;)
Twitter questions Vs answers
Ellkayy,
What’s the unique thing in Chromia that no other blockchain has, that makes you the better option?
Henrik Hjelte,
Unique: Chromia is the only blockchain that also has a real, proper database built-in. And blockchain is about managing data in a shared context. How to best managed data was solved in computer science already. So far, it is the relational algebra model that is used in 100% of all enterprises, and has an 85% market share. Chromia is the only blockchain that use that model and that power.
Ellkayy,
Why Chromia use RELL and not SQL or JavaScript? Can developers with other language knowledge use Chromia?
Serge,
Rell is the only language on the blockchain side. You can combine with anything on client-side, although now client only exists for JS/TS, C# and Java/Kotlin. Rell is a language for relational blockchain programming. It combines the following features:
1 Relational data modeling and queries similar to SQL. People familiar with SQL should feel at home once they learn the new syntax.
2 Normal programming constructs: variables, loops, functions, collections, etc.
3 Constructs which specifically target application backends and, in particular, blockchain-style programming including request routing, authorization, etc.
Rell aims to make programming as convenient and simple as possible. It minimizes boilerplate and repetition. At the same time, as a static type system it can detect and prevent many kinds of defects prior to run-time.
Roshan DV,
I have been monitoring your project for a while but some concerns about it: Your project will build your own core network, so you have more visibility than Ethereum and NEO. These are projects that were born before and which also have a very large community. And what can assure you that your project will guarantee the functionalities that you have defined?
Henrik Hjelte,
What came first? I want to remind that Vitalik was in the colored-coins project, led by our CTO and we had blockchain in production before ETH and NEO etc existed. We are the old dogs…
Large community: We are part of the same community. When developers are fustrated and want to try new tech, they go to us from other blockchains.
Also, we have a large potential: SQL (close to Rell and our tech) is the world top 3 language. Bigger than Java. Bigger than PHP. Only beaten bny HTML and javascript. Soliditiy is not on top 20 list. THere are millions of developers that know SQL. That is potential for community… (source is Stackoverflow annual programming survey).
Paul (Via Manage),
What are the utilities of Chromia and what purpose does the Chromia coin serve?
Serge,
Chromia meta-token called Chroma (CHR). It is used in Chromia to compensate block-producing nodes by fees. In Chromia, fees are paid by dapps, which can in their turn collect fees from users. Chromia provides mechanisms which balance the interests of developers and users. Dapp tokens can be automatically backed with Chroma, providing liquidity and value which is independent of investment into the dapp. Dapp investors can be compensated in Chroma through a profit-sharing contract. For developers, Chromia offers the opportunity to derive income from dapps. This incentivises the creation and maintenance of high quality dapps because better dapps generate more income and create more demand for tokens owned by the developer. The Chromia model is designed to support sustainable circular economies and foster a mutually beneficial relationship between developers, users, and investors.
Idemudia Isaac,
Thank you very much u/henrik_hjelte u/sergelubkin
You stated your plans for 2020 is to release series of dApps. What kind of large scale, mainstream decentralized application and $Chromia products do you think is suitable for the Nigerian environment?
Henrik Hjelte,
Actually, this is why we want to work with partners. We cannot know everything, For African market we have seen of course payments/remittances (but it has fallen out of trend). We would love to do real-estate /land-registration but we understand we need a strong local partner (more than a single person, a real company or organization driving).
●CC● | Elrond 🇵🇭,
What plans do you have to building a vibrant global community around Rell? And how would you go about encouraging/incentivising such ‘Rellists’ around the world to build dApps on Chromia? u/henrik_hjelte u/sergelubkin
Henrik Hjelte,
For developers (I am one too, or used to be) you normally need to prove a few things:
\ That the tech is productive (can I do apps faster?)*
\ That it is better (less bugs, more maintainable?)*
Then the community will come. We see that all the time. Look at web development. React.js came, and developers flooded to it. Not because of marketing on Superbowl, but because it was BETTER. Fewer bugs and easier to do complex webapps.
So, at core: people will come when we showcase the productivity gains, and that is what we need to focus on.
●CC● | Elrond 🇵🇭,
Why do you choose to build Chromia token on ERC20 instead of other blockchain such as BEP2, TRC20…or your own chain while ERC20 platform is very slow and have a case of fee? u/henrik_hjelte u/sergelubkin
Serge,
So far Ethereum has the best infrastructure, it’s the oldest and most reliable network for tokens. It also became the industry standard which exchanges utilize. We will transfer 80% of all erc20 tokens to our Chromia blockchain when it’s ready for that.
Koh,
In your whitepaper it says in the upcoming version of ChromiaWallet that it will be able to function as a Dapp browser for public use. Q) Will it be similar to the Dapp browser on Trust Wallet?
Serge,
It’s live already try it http://vault-testnet.chromia.com/
It’s the wallet and a dapp browser
CHROMIA is SOLID,
Your metamorphosis is a laudable one,surviving different FUD, how have you been able to survive this longest bear market and continue building and developing cos many projects have died out in this time period!
Henrik Hjelte,
You need to know we started a company before ETH existed. There was 0 money in blockchain when we started. I did it becuase it was fun, exciting tech and MAYBE someone would be interested in the thing we made “Tokens”…
We were never in the crazy bull-market, manly observed the crazies from the side. We fundraised for CHR in a dip (they called it bear market). ChromaWay the company also make money from enterprises.
Алекс,
What is SSO?
What makes it important for chromias ecosystem?
Why should we users be attracted to it?’
Serge,
Chromia SSO is perhaps the most important UX improvement that Chromia offers the decentralized world. It revolutionizes the way users interact with dapps. Any dapp requires users to sign transactions, that means they need a private key. Control of the private key is control of any and all dapps or assets associated with it. This means that private keys have an especially stringent set of security requirements in a blockchain context — they control real value, and there is no recourse if they are compromised or lost. https://blog.chromia.com/chromia-sso-the-whys-and-the-whats/
Olufemi Joel,
How do you see the Chromia project developing in 3 to 5 years, both on the commercial level and on the evolution of the company? What are the plans for expansion in different regions? Are you going to outsource the team/skills or keep it centralized and set up offices?
Henrik Hjelte,
I take part of the question. On outsource: we were a distributed team from day one, with co-founders from 3 countries (still living there). We are distributed now, Ukraine, Sweden, Vietnam, Croatia, China are “hubs” then we have individuals too. No big plan, just where we found great developers…
Park Lee, u/henrik_hjelte
You claim CHOROMIA have fast support, useful features with an affordable service cost. That fast and the fees are cheap but can you guarantee stability?
What’s the Algorithms which are used by CHROMIA for that fast? And Can you explain it?
Serge,
We use PBFT protocol with some features of DPOS, this plus sidechains parallelism offers almost unlimited speed and scalability. We also use the feature called anchoring to secure all transactions in batches on Bitcoin blockchain.
Mario Boy,
What are you guys trying to achieve as an end goal? The next Ethereum? Or the next enterprise version of Ethereum? Or something different?
Henrik Hjelte,
The end goal… good question. When we started in 2014 there were no other blockchain companies, so we wanted to do the best blockchain technology in order to enable a decentralized world with more fair applications. And that is what we still do. Technology/software that can enable people to make a fairer world
Erven James Sato,
“STAKING” is one of the STRATEGIES to ATTRACT USERS and ACHIEVE MASS ADOPTION
Does your GREAT PROJECT have plan about Staking?
Serge,
Yes, we announced our staking plans couple of months ago https://blog.chromia.com/on-providers-and-stakes/
We are working with our current partners to make it accessible for general public.
Chizoba,
I often see Chromia and ChromaWay being used interchangeably, what is the relationship between the two?
Henrik Hjelte,
ChromaWay the company started Chromia from code done as postchain. This is normal in open-source development, a company that leads development. But Chromia will be a decentalized network, so ChromaWay will not make direct money out of it more than if we have a role as a Provider (and get payed for hosting). ChromaWay can indirectly make money from optional support and maintenance etc. Also, this, perfectly normal in open-source world.
And it also benefits Chromia that there is a market for support.
A market open for competition.
No special treatment for “ChromaWay”
Enajite,
How to start coding on Chromia?
Henrik Hjelte,
Go to https://rell.chromia.com and follow the tutorial. Enjoy the free time you get compared to other blockchain languages…
●CC● | Elrond 🇵🇭,
Chromia process 500 TPS, these is slow compare to other Blockchains, where we can see now 60K TPS if more capacity require, how can that be? u/henrik_hjelte u/sergelubkin
Serge,
Yes, if you need faster speed you can use parallelism by having multiple blockchains for your dapp. Also, by optimization and better architecture sky is the limit.
Delphino.eth ⟠,
Can we consider Chromia an hybrid? For its mixing of Blockchain and a Database?
Henrik Hjelte,
Yes and no. I want to stress that Chromia is a FULL blockchain. It is not only “inspired”. It is a blockchain AND a database.
I tend to think about Hybrid more in the usecases that you might have as a customer. For example, a bank might want to have some data/transactions private (as a private blockchain) and have another half of the application with public data (on Chromia). So that is a hybrid solution, and Chromia ROCKS in that segment since it is the only blockchain that is complete relational database (what the normal world uses anyway for 85% of all applications)
Example area: “open banking”
Steve bush,
How will Chromia I have any empower Investors, Companies, Developers, Platform Users to
deliver impactful solutions and bring value to people all over the world?
Henrik Hjelte,
In order to make blockchain go big, we need to have users. Users need to be able to use apps with ease. Chromia have features like single-sign on (ease of use), but importantly do not require owning tokens to USE apps.
Also, it needs to be easy to make applications. For example, if you are a student in US and came up with an idea, you want to make an application for your school. Let’s call it “thefacebook”. You code something in PHP and MySQL. DID YOU SEE THAT. SQL. SQL.SQL. It is the same tech that Chromia has but no one else in the blockchain business. SQL rules the world if you look outside the crypto bubble. Google the Oracle head-office… 100% of all enterprises use it… Because it is easy and powerful.
And we even improve on SQL with Rell….
So, compare that with a hacky virtual machine that have a few years…. 😊
August,
“Mines of Dalarnia” is a game that has caught my attention a lot, due to its simplicity and quality. But in the time that I have used it I have not been able to differentiate between the Chromia blockchain of this game and that of the competition? What other games do you have next to develop? I would like to give ideas in those games like a Gamers!
Henrik Hjelte,
We thought about in corona time sports club might want to engage more with their fans digitally. And of course, E-Sports is getting a real momentum as the young generation grows up. Now a bit sad that all games are centralized. My daughter will be sad when (at some day?) they will close down roblox… it happens to all centralized apps eventually… that is what we fix. Power to the Public to control apps and their future. I’ll repost again Alex post. Sorry I like it a lot… https://blog.chromia.com/towards-publicly-hosted-applications/
Bisolar,
Good day Chromia team from a Chromia fan
Can you tell us Chromia’s geographical focus at the moment and the proces it follows for it BUSINESS DEVELOPMENT?
What factors do you consider before identifying NEW MARKETS to enter?
Serge,
Chromia will initially focus on community building in China, Korea, US and Europe. The focus of community growth will gradually expand to other markets as the project gains popularity.
Current community growth strategies of Chromia include:
Chromia blockchain incubator creation to welcome more projects to the Chromia blockchain
Host blockchain gaming conferences, workshops, and meetups to engage with potential users.
Provide online and face-to-face tutorials to engage with dapps developers.
Attract blockchain developers through direct and indirect approach via specialized platforms and communities.
Develop our relations with existing and previous corporate clients, and their partnership networks to participate in their blockchain ventures
Launch Node program to encourage system providers to run nodes on the Chromia blockchain.
Staking program for Chroma (CHR) tokens
Active community engagement via social channels.
Future community growth strategies of Chromia after Mainnet launch include:
Partner with more gaming studios, startups and enterprises
Build local communities with Ambassador Programs.
Partner with external incubator and accelerators to provide blockchain expertise and introduce projects to Chromia ecosystem
Continue organizing hackathons around the world to attract more developers.
Emmanuel,
I want to know the current structure of your roadmap? What is the future roadmap of CHROMIA? Is there any key milestone coming???
Henrik Hjelte,
It is easy to do a roadmap; anyone can make a pape plan. But I think they are used in the wrong way. Software is hard, blockchain is even harder because it NEEDS TO BE SECURE. No MVP releases. We cannot even have roadmap deadlines and skimp on quality. Where we are now though is: Rell language finished so much that developers can write apps and see its magic. We have external devs doing dapps. We have the first phase of mainnet. We have a series of releases coming up. We will release mainnet when it is secure enough, and gradual roll out. I think quite soon, development is going great at the moment, a bit quicker than we though.
Ellkayy,
Why doesn’t Chromia transactions use gas? How do you power transactions then?
Serge,
Main feature of gas in Ethereum is to pay for transactions for miners get rewards. In our scenario Providers get rewards from dapp owners. So dapp owner pays for storing their dapp. It’s like Amazon Web Service model. Then dapp owner can monetize it in its own way.
Ellkayy,
Many developers don’t know RELL, just Solidity and SQL. Is this a barrier or threat to Chromia? Why RELL is better?
Henrik Hjelte,
Very few developers know Solidity. Do a search on github. I referred previously to stackoverflow programming language survey results. https://insights.stackoverflow.com/survey/2019#technology
If you know SQL, you learn Rell in a day.
SQL is the top 3 language here. I’d say there are millions that can easily jump to Rell.
Soldity or other blockchains, not on top 20 list even.
Rell is a hipper, nicer version of SQL that is also a “normal” programming language.
Developers like to learn new things, new languages. Otherwise we would be stuck with PHP, the DOMINANT language. Well, is it still? Seems javascript and react.js and node etc is taking over…

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.
  • Bitcoin (BTC) is a peer-to-peer cryptocurrency that aims to function as a means of exchange that is independent of any central authority. BTC can be transferred electronically in a secure, verifiable, and immutable way.
  • Launched in 2009, BTC is the first virtual currency to solve the double-spending issue by timestamping transactions before broadcasting them to all of the nodes in the Bitcoin network. The Bitcoin Protocol offered a solution to the Byzantine Generals’ Problem with a blockchain network structure, a notion first created by Stuart Haber and W. Scott Stornetta in 1991.
  • Bitcoin’s whitepaper was published pseudonymously in 2008 by an individual, or a group, with the pseudonym “Satoshi Nakamoto”, whose underlying identity has still not been verified.
  • The Bitcoin protocol uses an SHA-256d-based Proof-of-Work (PoW) algorithm to reach network consensus. Its network has a target block time of 10 minutes and a maximum supply of 21 million tokens, with a decaying token emission rate. To prevent fluctuation of the block time, the network’s block difficulty is re-adjusted through an algorithm based on the past 2016 block times.
  • With a block size limit capped at 1 megabyte, the Bitcoin Protocol has supported both the Lightning Network, a second-layer infrastructure for payment channels, and Segregated Witness, a soft-fork to increase the number of transactions on a block, as solutions to network scalability.

1. What is Bitcoin (BTC)?

  • Bitcoin is a peer-to-peer cryptocurrency that aims to function as a means of exchange and is independent of any central authority. Bitcoins are transferred electronically in a secure, verifiable, and immutable way.
  • Network validators, whom are often referred to as miners, participate in the SHA-256d-based Proof-of-Work consensus mechanism to determine the next global state of the blockchain.
  • The Bitcoin protocol has a target block time of 10 minutes, and a maximum supply of 21 million tokens. The only way new bitcoins can be produced is when a block producer generates a new valid block.
  • The protocol has a token emission rate that halves every 210,000 blocks, or approximately every 4 years.
  • Unlike public blockchain infrastructures supporting the development of decentralized applications (Ethereum), the Bitcoin protocol is primarily used only for payments, and has only very limited support for smart contract-like functionalities (Bitcoin “Script” is mostly used to create certain conditions before bitcoins are used to be spent).

2. Bitcoin’s core features

For a more beginner’s introduction to Bitcoin, please visit Binance Academy’s guide to Bitcoin.

Unspent Transaction Output (UTXO) model

A UTXO transaction works like cash payment between two parties: Alice gives money to Bob and receives change (i.e., unspent amount). In comparison, blockchains like Ethereum rely on the account model.
https://preview.redd.it/t1j6anf8f3151.png?width=1601&format=png&auto=webp&s=33bd141d8f2136a6f32739c8cdc7aae2e04cbc47

Nakamoto consensus

In the Bitcoin network, anyone can join the network and become a bookkeeping service provider i.e., a validator. All validators are allowed in the race to become the block producer for the next block, yet only the first to complete a computationally heavy task will win. This feature is called Proof of Work (PoW).
The probability of any single validator to finish the task first is equal to the percentage of the total network computation power, or hash power, the validator has. For instance, a validator with 5% of the total network computation power will have a 5% chance of completing the task first, and therefore becoming the next block producer.
Since anyone can join the race, competition is prone to increase. In the early days, Bitcoin mining was mostly done by personal computer CPUs.
As of today, Bitcoin validators, or miners, have opted for dedicated and more powerful devices such as machines based on Application-Specific Integrated Circuit (“ASIC”).
Proof of Work secures the network as block producers must have spent resources external to the network (i.e., money to pay electricity), and can provide proof to other participants that they did so.
With various miners competing for block rewards, it becomes difficult for one single malicious party to gain network majority (defined as more than 51% of the network’s hash power in the Nakamoto consensus mechanism). The ability to rearrange transactions via 51% attacks indicates another feature of the Nakamoto consensus: the finality of transactions is only probabilistic.
Once a block is produced, it is then propagated by the block producer to all other validators to check on the validity of all transactions in that block. The block producer will receive rewards in the network’s native currency (i.e., bitcoin) as all validators approve the block and update their ledgers.

The blockchain

Block production

The Bitcoin protocol utilizes the Merkle tree data structure in order to organize hashes of numerous individual transactions into each block. This concept is named after Ralph Merkle, who patented it in 1979.
With the use of a Merkle tree, though each block might contain thousands of transactions, it will have the ability to combine all of their hashes and condense them into one, allowing efficient and secure verification of this group of transactions. This single hash called is a Merkle root, which is stored in the Block Header of a block. The Block Header also stores other meta information of a block, such as a hash of the previous Block Header, which enables blocks to be associated in a chain-like structure (hence the name “blockchain”).
An illustration of block production in the Bitcoin Protocol is demonstrated below.

https://preview.redd.it/m6texxicf3151.png?width=1591&format=png&auto=webp&s=f4253304912ed8370948b9c524e08fef28f1c78d

Block time and mining difficulty

Block time is the period required to create the next block in a network. As mentioned above, the node who solves the computationally intensive task will be allowed to produce the next block. Therefore, block time is directly correlated to the amount of time it takes for a node to find a solution to the task. The Bitcoin protocol sets a target block time of 10 minutes, and attempts to achieve this by introducing a variable named mining difficulty.
Mining difficulty refers to how difficult it is for the node to solve the computationally intensive task. If the network sets a high difficulty for the task, while miners have low computational power, which is often referred to as “hashrate”, it would statistically take longer for the nodes to get an answer for the task. If the difficulty is low, but miners have rather strong computational power, statistically, some nodes will be able to solve the task quickly.
Therefore, the 10 minute target block time is achieved by constantly and automatically adjusting the mining difficulty according to how much computational power there is amongst the nodes. The average block time of the network is evaluated after a certain number of blocks, and if it is greater than the expected block time, the difficulty level will decrease; if it is less than the expected block time, the difficulty level will increase.

What are orphan blocks?

In a PoW blockchain network, if the block time is too low, it would increase the likelihood of nodes producingorphan blocks, for which they would receive no reward. Orphan blocks are produced by nodes who solved the task but did not broadcast their results to the whole network the quickest due to network latency.
It takes time for a message to travel through a network, and it is entirely possible for 2 nodes to complete the task and start to broadcast their results to the network at roughly the same time, while one’s messages are received by all other nodes earlier as the node has low latency.
Imagine there is a network latency of 1 minute and a target block time of 2 minutes. A node could solve the task in around 1 minute but his message would take 1 minute to reach the rest of the nodes that are still working on the solution. While his message travels through the network, all the work done by all other nodes during that 1 minute, even if these nodes also complete the task, would go to waste. In this case, 50% of the computational power contributed to the network is wasted.
The percentage of wasted computational power would proportionally decrease if the mining difficulty were higher, as it would statistically take longer for miners to complete the task. In other words, if the mining difficulty, and therefore targeted block time is low, miners with powerful and often centralized mining facilities would get a higher chance of becoming the block producer, while the participation of weaker miners would become in vain. This introduces possible centralization and weakens the overall security of the network.
However, given a limited amount of transactions that can be stored in a block, making the block time too longwould decrease the number of transactions the network can process per second, negatively affecting network scalability.

3. Bitcoin’s additional features

Segregated Witness (SegWit)

Segregated Witness, often abbreviated as SegWit, is a protocol upgrade proposal that went live in August 2017.
SegWit separates witness signatures from transaction-related data. Witness signatures in legacy Bitcoin blocks often take more than 50% of the block size. By removing witness signatures from the transaction block, this protocol upgrade effectively increases the number of transactions that can be stored in a single block, enabling the network to handle more transactions per second. As a result, SegWit increases the scalability of Nakamoto consensus-based blockchain networks like Bitcoin and Litecoin.
SegWit also makes transactions cheaper. Since transaction fees are derived from how much data is being processed by the block producer, the more transactions that can be stored in a 1MB block, the cheaper individual transactions become.
https://preview.redd.it/depya70mf3151.png?width=1601&format=png&auto=webp&s=a6499aa2131fbf347f8ffd812930b2f7d66be48e
The legacy Bitcoin block has a block size limit of 1 megabyte, and any change on the block size would require a network hard-fork. On August 1st 2017, the first hard-fork occurred, leading to the creation of Bitcoin Cash (“BCH”), which introduced an 8 megabyte block size limit.
Conversely, Segregated Witness was a soft-fork: it never changed the transaction block size limit of the network. Instead, it added an extended block with an upper limit of 3 megabytes, which contains solely witness signatures, to the 1 megabyte block that contains only transaction data. This new block type can be processed even by nodes that have not completed the SegWit protocol upgrade.
Furthermore, the separation of witness signatures from transaction data solves the malleability issue with the original Bitcoin protocol. Without Segregated Witness, these signatures could be altered before the block is validated by miners. Indeed, alterations can be done in such a way that if the system does a mathematical check, the signature would still be valid. However, since the values in the signature are changed, the two signatures would create vastly different hash values.
For instance, if a witness signature states “6,” it has a mathematical value of 6, and would create a hash value of 12345. However, if the witness signature were changed to “06”, it would maintain a mathematical value of 6 while creating a (faulty) hash value of 67890.
Since the mathematical values are the same, the altered signature remains a valid signature. This would create a bookkeeping issue, as transactions in Nakamoto consensus-based blockchain networks are documented with these hash values, or transaction IDs. Effectively, one can alter a transaction ID to a new one, and the new ID can still be valid.
This can create many issues, as illustrated in the below example:
  1. Alice sends Bob 1 BTC, and Bob sends Merchant Carol this 1 BTC for some goods.
  2. Bob sends Carols this 1 BTC, while the transaction from Alice to Bob is not yet validated. Carol sees this incoming transaction of 1 BTC to him, and immediately ships goods to B.
  3. At the moment, the transaction from Alice to Bob is still not confirmed by the network, and Bob can change the witness signature, therefore changing this transaction ID from 12345 to 67890.
  4. Now Carol will not receive his 1 BTC, as the network looks for transaction 12345 to ensure that Bob’s wallet balance is valid.
  5. As this particular transaction ID changed from 12345 to 67890, the transaction from Bob to Carol will fail, and Bob will get his goods while still holding his BTC.
With the Segregated Witness upgrade, such instances can not happen again. This is because the witness signatures are moved outside of the transaction block into an extended block, and altering the witness signature won’t affect the transaction ID.
Since the transaction malleability issue is fixed, Segregated Witness also enables the proper functioning of second-layer scalability solutions on the Bitcoin protocol, such as the Lightning Network.

Lightning Network

Lightning Network is a second-layer micropayment solution for scalability.
Specifically, Lightning Network aims to enable near-instant and low-cost payments between merchants and customers that wish to use bitcoins.
Lightning Network was conceptualized in a whitepaper by Joseph Poon and Thaddeus Dryja in 2015. Since then, it has been implemented by multiple companies. The most prominent of them include Blockstream, Lightning Labs, and ACINQ.
A list of curated resources relevant to Lightning Network can be found here.
In the Lightning Network, if a customer wishes to transact with a merchant, both of them need to open a payment channel, which operates off the Bitcoin blockchain (i.e., off-chain vs. on-chain). None of the transaction details from this payment channel are recorded on the blockchain, and only when the channel is closed will the end result of both party’s wallet balances be updated to the blockchain. The blockchain only serves as a settlement layer for Lightning transactions.
Since all transactions done via the payment channel are conducted independently of the Nakamoto consensus, both parties involved in transactions do not need to wait for network confirmation on transactions. Instead, transacting parties would pay transaction fees to Bitcoin miners only when they decide to close the channel.
https://preview.redd.it/cy56icarf3151.png?width=1601&format=png&auto=webp&s=b239a63c6a87ec6cc1b18ce2cbd0355f8831c3a8
One limitation to the Lightning Network is that it requires a person to be online to receive transactions attributing towards him. Another limitation in user experience could be that one needs to lock up some funds every time he wishes to open a payment channel, and is only able to use that fund within the channel.
However, this does not mean he needs to create new channels every time he wishes to transact with a different person on the Lightning Network. If Alice wants to send money to Carol, but they do not have a payment channel open, they can ask Bob, who has payment channels open to both Alice and Carol, to help make that transaction. Alice will be able to send funds to Bob, and Bob to Carol. Hence, the number of “payment hubs” (i.e., Bob in the previous example) correlates with both the convenience and the usability of the Lightning Network for real-world applications.

Schnorr Signature upgrade proposal

Elliptic Curve Digital Signature Algorithm (“ECDSA”) signatures are used to sign transactions on the Bitcoin blockchain.
https://preview.redd.it/hjeqe4l7g3151.png?width=1601&format=png&auto=webp&s=8014fb08fe62ac4d91645499bc0c7e1c04c5d7c4
However, many developers now advocate for replacing ECDSA with Schnorr Signature. Once Schnorr Signatures are implemented, multiple parties can collaborate in producing a signature that is valid for the sum of their public keys.
This would primarily be beneficial for network scalability. When multiple addresses were to conduct transactions to a single address, each transaction would require their own signature. With Schnorr Signature, all these signatures would be combined into one. As a result, the network would be able to store more transactions in a single block.
https://preview.redd.it/axg3wayag3151.png?width=1601&format=png&auto=webp&s=93d958fa6b0e623caa82ca71fe457b4daa88c71e
The reduced size in signatures implies a reduced cost on transaction fees. The group of senders can split the transaction fees for that one group signature, instead of paying for one personal signature individually.
Schnorr Signature also improves network privacy and token fungibility. A third-party observer will not be able to detect if a user is sending a multi-signature transaction, since the signature will be in the same format as a single-signature transaction.

4. Economics and supply distribution

The Bitcoin protocol utilizes the Nakamoto consensus, and nodes validate blocks via Proof-of-Work mining. The bitcoin token was not pre-mined, and has a maximum supply of 21 million. The initial reward for a block was 50 BTC per block. Block mining rewards halve every 210,000 blocks. Since the average time for block production on the blockchain is 10 minutes, it implies that the block reward halving events will approximately take place every 4 years.
As of May 12th 2020, the block mining rewards are 6.25 BTC per block. Transaction fees also represent a minor revenue stream for miners.

HUOBI EXCHANGE REVIEW

HUOBI EXCHANGE REVIEW
Huobi is a Singapore-based cryptocurrency exchange. Founded in China, the company now has offices in Hong Kong, Korea, Japan and the United States. In August 2018 it became a publicly listed Hong Kong company.
Recently during early 2019, after crypto communities lost interest in ICOs (Initial Coin Offering) due to many unregistered STOs (Security Token Offering) and other projects whose aim was only to raise the funds. Exchanges adapted and gave a new dimension of the fund raising, IEO (Initial Exchange Offering).
In this regard, exchanges helped the projects by providing them a platform to raise the funds and also helped the retail investors by doing due diligence on the project on behalf of the investors. Best part of this process is, such issued tokens are listed on the same platform and exchanges helped these start ups in the process. This gave a sense of security and helped to maintain integrity with the projects and public investors.
All the top tier exchanges are participating in this movement and named such fund raising as Launchpad, Jumpstart, Spotlight, Startup etc. While Huobi came up with Huobi Prime.
Unlike other exchanges, Huobi Prime has helped varieties of start-ups.
  • It all started with a DAG based blockchain platform, Top Network.
  • A project named after the greatest scientist who made a major impact on the human lives, Newton Project. It is aimed to deliver an infrastructure for the community economy.
  • It is followed by Thunder Core. A blockchain project dreamt of decentralized future and allows anyone to build dApps on their platform.
  • Then Reserve Rights continued the legacy. It’s a protocol for stable currencies with three kinds of tokens RSV, RSR and collateral tokens.
  • Akropolis - a protocol to explore the informal economy and help the people with DeFi. It was one of it’s kind which was competitive enough to seek the help from the Huobi.
  • Later a social digital currency, Emogi secured a place to be the next Prime project.
  • Recently, Whole Network - A consensus, co-creation, and win-win behavioral value network had the opportunity to feature as a 7th Prime project.
However, each of the Prime project is different from the other in the list. One must admit, it is a basket with mixed fruits. From DAG to Currency to dApp platform to stable coin protocol to DeFi protocol to digital currency to blockchain phone. Huobi has covered a rich list of projects in this journey.

(This chart presents the information based on the price of the each token on 2nd October. However it may vary marginally as price of the cryptocurrencies are volatile in nature)
Trading Options
Many centralized exchanges serve as the sole, centralized market maker. In contrast, Huobi also allows you to trade over the counter (OTC). This means that you can buy and sell cryptocurrencies peer-to-peer on Huobi. Even though this option exists on the exchange, it has yet to gain adoption from traders. Various commenters have said that there is a lack of OTC offers. Still, this is still an innovative technical feature.

If you are a margin trader, Houbi has a separate platform specifically for this. You can access this by going to the margin tab in the header. The amount of leverage you can have varies from coin-to-coin. For example, BTC is around 3x. Compared to other margin trading platforms, this is low. Nonetheless, it is an attractive option for potential users.

In December 2018, Huobi Derivative Market issued BTC contracts and ETH contracts (including weekly, bi-weekly and quarterly, respectively), and flexible leverages, including 1x, 5x, 10x and 20x. In the future, more digital currencies will be issued to meet various investment demands.
Meaning “currency” in Mandarin Chinese, Huobi consistently ranks as one of the world’s top ten largest exchanges by trade volume. In this article, we look at everything you need to know as a potential Huobi user. Let’s examine fees, fund security, customer experience and more.

User Interface and Mobile App

Available on iOS and Android, the Huobi mobile app features most of the functionalities available on the web platform. You can even complete tasks like account registration and verification directly via the app. In Google Play, the Huobi Global app has an average rating of 4.1 stars out of 3,730 reviews. However, in December 2018 and January 2019, some users have said that the Android app won’t let them login due to an error with Captcha. On the Apple App Store, Huobi boasts an average rating of 4.9 stars out of over 4,800 reviews.

Huobi offers a margin trading option.

Security

Compared to other exchanges, Huobi continues to excel from a security perspective. Many top exchanges suffer from large-scale hacks, with varying results in terms of trading volume afterward. In 2015, a Bitstamp hacker withdrew 12,000 BTC from Huobi. However, this issue did not relate to the security of Huobi. Huobi reported a DDOS attack in 2015 but this did not cause a security breach. According to one review, an individual user lost USDT and EOS on Huobi. This reviewer states that the problem was caused by a technical error with Huobi’s 2FA. One comment suggests that it was the result of a phishing scam.

Huobi claims that its risk controls have been developed by the likes of Goldman Sachs. The exchange stores around 98 percent of funds in cold wallets. Moreover, Huobi now utilizes a decentralized exchange structure to prevent DDOS attacks. The exchange even has a User Protection Fund Initiative. Twenty percent of net revenue that the exchanges gains from trades will go to this fund, which it will use to buy back Huobi Token (HT). It also has a service called Huobi Security Reserve. As part of this, the exchange plans to store 20,000 BTC for insurance. This is a preventative measure that will help Huobi reimburse users in the case of any future hacks.

Huobi Fees

Huobi has a 0.2 percent fee that applies to both market makers and takers for amounts between $0 and $5,000,000 over the course of a 30-day period. In comparison, other top exchanges like Binance have 0.1 percent fees. Meanwhile, GDAX has 0.3 percent fees.

In January 2019, Huobi Global launched a tiered fee structure that significantly reduces fees for higher volume traders. This is relatively competitive when compared to other exchanges. Users also have the option to reduce trading fees on Huobi by becoming a VIP member. This involves paying a monthly payment of HT, which varies depending on the membership level (1-5).

Like most exchanges Huobi has no fees on deposits. However, Huobi does have withdrawal fees and minimums that vary from coin-to-coin. For example, withdrawing Bitcoin (BTC) costs 0.001 BTC, with a minimum withdrawal amount of 0.01 BTC. For Tether (USDT), the flat fee is 5 USDT and minimum withdrawal amount is 20 USDT. Overall, this means that Huobi fees are generally higher than most exchanges for lower withdrawal amounts. A few exceptions exist. For example, TUSD has a withdrawal minimum of $20 but a withdrawal fee of only $2.

Withdrawal Limitations

Similar to many exchanges on the market, Huobi has withdrawal limitations based on various levels of user verification. One thing you will notice is that withdrawal amounts vary greatly depending on your citizenship. For example, if you are a citizen of China, you can’t withdraw any funds as an unverified user or with level 1 verification. This option is only available at level 2 or above. In the United States, the exchange only requires level 1 verification. However, the amounts are relatively low: a daily limit of $2,000 and a monthly limit of $10,000.

Customer Service Experience

Compared to most exchanges, Huobi has above average customer service experience. Customer support is available 24/7, and response times only take two to three hours on average. Many consider this to be a rarity in the space.

There are two main methods that you can use to reach customer support. First, you can utilize the chat app that is available directly on the Huobi trading platform. Second, you can contact the team at [[email protected]](mailto:[email protected]). If you choose this option, Huobi asks that you use the registered email address associated with your Huobi account and include your user ID.

2019 in Review: Community, Crime, Courtcases, Craig & Consolidation

2019 in Review: Community, Crime, Courtcases, Craig & Consolidation

https://preview.redd.it/r7dmpveldia41.png?width=680&format=png&auto=webp&s=f7dc87d5b58c4391d3e04359c4dc111d771246a1
2019 has been a tumultuous but amazing year for the development and advancement of blockchain technology. Following the rally to the all-time-highs at the end of 2017 and the intense infrastructure development and ongoing Bear Market of 2018 it was clear things were changing quickly. We are about to enter a new decase and the team at Aelf wanted to look back at 2019 and reflect on some of the events that occurred over the last year to see where the industry might be headed in 2020.

https://preview.redd.it/tccwloemdia41.png?width=384&format=png&auto=webp&s=3c9feac47c8e8accc602dee7e738df86facc3e2e
Although the year has been considered a continuation of the 2018 bear market, it didn’t stop development, progression and a myriad of crazy events from occurring. This included the challenges associated with global regulations, the upcoming Bitcoin halving event in May 2020, announcement of the Facebook Libra and Telegram Open Network’s (TON) launch delay. This year also saw a myriad of debacles from self-proclaimed Bitcoin creator Craig Wright, the Justin Sun and Warren Buffet lunch situation, the recent claim of Twitter CEO Jack Dorsey’s goal to modify Twitter into a decentralized version of the platform, and President Trump’s Bitcoin statement, among others. Now let’s examine more of what took place during 2019 as we approach the start of the New Year in 2020.
The SEC, Telegram, Facebook Libra, Kik and Blockchain’s Global Regulatory Environment
Many of the world’s governments have been harsh towards blockchain technology in recent years. Particularly, the US Government and the Securities and Exchange Commission (SEC) have been very reluctant to ease the regulatory framework for blockchain development in the country. This has become more evident in 2019, with the SEC combatting many blockchain projects this year including the $1.7 billion-dollar token offering of the Telegram Open Network
and the Facebook Libra project. As well the SEC created controversy in a gruesome battle with Kik over its alleged illegal token offering that Kik has sworn to fight to their last breath.

https://preview.redd.it/6yngxxfndia41.png?width=614&format=png&auto=webp&s=dc363d1a2225f461bad20786e8439e7cc3896d7d
Many proponents of blockchain technology accuse the SEC of unfair policies to put a stranglehold on the development on blockchain in order to prevent the devaluation of the American monetary system. The reluctance for crypto exchanges to set up shop in the US is also becoming more prevalent because of the supposedly biased and unfavourable approach of the SEC. Nevertheless, there are also several major countries including China that have for the most part embraced the advancement of blockchain technology in 2019. China has also nearly finalized the development of the digital Chinese Yuan and announced that that country is going all in on blockchain development despite its sometimes anti-Bitcoin approach.
The Bitcoin Halving Event and its Ongoing Effect on Market Conditions
With the end of 2019 nearly upon us and the upcoming Bitcoin halving event set to take place during May of 2020 the market could be overdue for a bull market of mass proportions. Remember, the last bull market that took place was 2 years ago during December 2017 and was followed by an incredible dump from the all-time-high price of 20 thousand US Dollars to just 3300 USD in December 2018. For the most part, 2018 was a blood-bath for crypto markets and 2019 has not been all that much better. The price did briefly rally up to 14 thousand US Dollars during mid 2019 but has since been reduce by half with the Bitcoin price presently at just over 7000 US Dollars. Bitcoin was designed by its original creators with code written to mitigate the negative effects of inflation. In order to curb inflation, once every 4 years (or 210,000 blocks) the mining rewards that the network automatically generates are reduced in half.

3 Additional Stories to Watch in 2020
In June, the CEO of Tron, Justin Sun purchased tickets through eBay for a charity auction to have lunch with Warren Buffet. Sun paid a record $4.56 million US Dollars in the process becoming the highest bid in the 20-year history of the event. The purpose of the lunch from Sun’s standpoint is to change Mr. Buffet’s viewpoint towards crypto and blockchain tech by inviting several blockchain industry leaders to help sway the famous investor’s perspective. Sun subsequently missed the lunch he scheduled in September because of a sudden bout with kidney stones. At this time, the community will have to wait and see when Sun and Buffet will meet in 2020. Stay tuned.
Back in December of 2015, Craig Wright claimed publicly to be the creator of Bitcoin, Satoshi Nakamoto. Most believe Wright was lying to gain more fame and recognition in the industry. On November 18th, 2018 Bitcoin SV hard forked from the Bitcoin Cash Network to create it own chain. As noted above, the disgruntled CEO of Bitcoin SV, has for years maintained he led the initial development of Bitcoin. During February 2018, Wright was the subject of a 5.118-Billion-dollar lawsuit by Dave Kleiman claiming that Wright defrauded Kleiman of Bitcoin while working on the initial development of the Bitcoin Network between 2009 and 2013. In August 2019, Wright was ordered by a court of law to pay half the 5.11 Billion in Bitcoin back to Kleiman. Throughout 2019, Wright launched lawsuits against Ethereum founder Vitalik Buterin, Bitcoin Cash’s Roger Ver and others for calling him a fraud. It seems likely Wright will continue his ongoing Satoshi rhetoric in 2020.

The CEO of Twitter, Jack Dorsey recently stated that he has hired 5 full-time employees to modify the Twitter platform and make it increasingly decentralized. This may seem like a small step initially, but this project could be expanded easily by someone of Dorsey’s reputation and wealth in the technology industry. Dorsey himself has been a long-term proponent of blockchain technology and an investor in Bitcoin. Binance CEO, Changpeng Zhao, recently offered to help Dorsey make this dream come to fruition. Additionally, Morgan Creek Capital founder Anthony Pompliano supported Dorsey’s statement noting that, “Jack Dorsey may understand the future better than any entrepreneur on the planet right now.”
Conclusion
This year we saw Kik, Telegram and Facebook Libra face fierce backlash from the most powerful regulatory body in the world, the SEC. We saw the Chinese government announce that they are all in on blockchain development and declare the upcoming launch of their own centralized digital Chinese Yuan. Justin Sun postponed his 4.56-million-dollar lunch with billionaire investor Warren Buffet because of health issues, while Jack Dorsey the CEO of Twitter proclaimed a more decentralized and open version of Twitter to prevent some of the abuse on the platform.
In 2019, the 4-year long Craig Wright and Satoshi Nakamoto saga continued, and we finally are moving closer to the much-anticipated Bitcoin halving event of May 2020 that could change the trajectory of the Bitcoin price for much of 2020 and 2021. It is clear 2019 has been an incredible year for the blockchain industry. With no shortage of uncertainty and scepticism in the short-term, it is likely that 2019 will pale in comparison to the developments of 2020. As we approach 2020, the industry will continue to expand towards mass adoption and the mainstream evolution of blockchain technology. Nevertheless, with the global regulatory blockchain environment evolving in many areas across the world, the uncertainty in the United States remains stronger than ever. There is no telling what will happen in this regard and what will happen with Bitcoin and this amazing revolution in 2020 and beyond.
Merry Christmas and Happy Holidays from the Aelf Blockchain team and a Happy 2020 to all our community members!! Thank You

Playing with fire with FinCen and SEC, Binance may face a hefty penalty again after already losing 50 percent of its trading business

On 14 June, Binance announced that it “constantly reviews user accounts to improve (their) platform security and to comply with global compliance requirements”, mentioning that “Binance is unable to provide services to any U.S. person” in the latest “Binance Terms of Use” attached within the announcement.
According to the data from a third-party traffic statistics website, Alexa, users in the U.S. form the biggest user group of Binance, accounting for about 25% of the total visitor traffic.
In the forecast of Binance’s user scale compiled by The Block, the largest traffic is dominated by users in the U.S., surpassing the total of the ones from the second place to the fifth place.
Also, considering that the scale of digital asset trading for the users in the U.S. far exceeds that of the users of many other countries, it could mean that Binance may have already lost 50 % of the business income by losing users in the U.S. Apparently, such an announcement by Binance to stop providing services to users in the U.S. means Binance has no other alternative but “seek to live on.”
So, what are the specific requirements of the U.S. for digital asset exchanges and which of the regulatory red lines of the U.S. did Binance cross?
Compliance issues relating to operation permission of digital asset exchanges
In the U.S., the entry barrier for obtaining a business license to operate a digital asset exchange is not high. Apart from the special licencing requirements of individual states such as New York, most of the states generally grant licences to digital asset exchanges through the issuance of a “Money Transmitter License” (MTL).
Each state has different requirements for MTL applications. Some of the main common requirements are:
Filling out the application form, including business address, tax identification number, social security number and statement of net assets of the owneproprietor Paying the relevant fees for the licence application Meeting the minimum net assets requirements stipulated by the state Completing a background check Providing a form of guarantee, such as security bonds
It is worth noting that not all states are explicitly using MTL to handle the issues around operation permission of digital asset exchanges. For instance, New Hampshire passed a new law on 12 March 2017, announcing that trading parties of digital assets in that state would not be bound by MTL. Also, Montana has not yet set up MTL, keeping an open attitude towards the currency trading business.
On top of obtaining the MTL in each state, enterprises are also required to complete the registration of “Money Services Business” (MSB) on the federal level FinCEN (Financial Crimes Enforcement Network of the U.S. Treasury Department) issued the “Application of FinCEN’s Regulations to Persons Administering, Exchanging, or Using Virtual Currencies” on 18 March 2013. On the federal level, the guideline requires any enterprise involved in virtual currency services to complete the MSB registration and perform the corresponding compliance responsibilities. The main responsibility of a registered enterprise is to establish anti-money laundering procedures and reporting systems.
However, California is an exception. Enterprises in California would only need to complete the MSB registration on the federal level and they do not need to apply for the MTL in California.
Any enterprise operating in New York must obtain a virtual currency business license, Bitlicense, issued in New York
Early in July 2014, the New York State Department of Financial Services (NYSDFS) has specially designed and launched the BitLicense, stipulating that any institutions participating in a business relevant to virtual currency (virtual currency transfer, virtual currency trust, provision of virtual currency trading services, issuance or management of virtual currencies) must obtain a BitLicense.
To date, the NYSDFS has issued 19 Bitlicenses. Among them includes exchanges such as Coinbase (January 2017), BitFlyer (July 2017), Genesis Global Trading (May 2018) and Bitstamp (April 2019).
Solely from the perspective of operation permission, Binance has yet to complete the MSB registration of FinCEN (its partner, BAM Trading, has completed the MSB registration). This means that Binance is not eligible to operate a digital asset exchange in the U.S. FinCEN has the rights to prosecute Binance based on its failure to fulfil the relevant ‘anti-money laundering’ regulatory requirements.
Compliance issues relating to online assets
With the further development of the digital asset market, ICO has released loads of “digital assets” that have characteristics of a “security” into the trading markets. The Securities and Exchange Commission (SEC) has proposed more comprehensive compliance requirements for digital asset exchanges. The core of the requirements is reflected in the restrictions of offering digital assets trading service.
In the last two years, the SEC has reiterated on many occasions that digital assets that have characteristics of a security should not be traded on a digital asset exchange
In August 2017, when the development of ICO was at its peak, the SEC issued an investor bulletin “Investor Bulletin: Initial Coin Offerings” on its website and published an investigation report of the DAO. It determined that the DAO tokens were considered ‘marketable securities’, stressing that all digital assets considered ‘marketable securities’ would be incorporated into the SEC regulatory system, bound by the U.S. federal securities law. Soon after, the SEC also declared and stressed that “(if) a platform offers trading of digital assets that are securities and operates as an “exchange,” as defined by the federal securities laws, then the platform must register with the SEC as a national securities exchange or be exempt from registration.”
On 16 November 2018, the SEC issued a “Statement on Digital Asset Securities Issuance and Trading,” in which the SEC used five real case studies to conduct exemplary penalty rulings on the initial offers and sales of digital asset securities, including those issued in ICOs, relevant cryptocurrency exchanges, investment management tools, ICO platforms and so on. The statement further reiterates that exchanges cannot provide trading services for digital assets that have characteristics of a security.
On 3 April 2019, the SEC issued the “Framework for ‘Investment Contract’ Analysis of Digital Assets” to further elucidate the evaluation criteria for determining whether a digital asset is a security and providing guiding opinions on the compliance of the issuance, sales, holding procedures of digital assets.
As of now, only a small number of digital assets, such as BTC, ETH, etc. meet the SEC’s requirement of “non-securities assets.” The potentially “compliant” digital assets are less than 20.
Early in March 2014, the Inland Revenue Service (IRS) has stated that Bitcoin will be treated as a legal property and will be subject to taxes. In September 2015, the U.S. Commodity Futures Trading Commission (CFTC) stated that Bitcoin is a commodity and will be treated as a “property” by the IRS for tax purposes.
On 15 June 2018, William Hinman, Director of the Corporate Finance Division of the SEC, said at the Cryptocurrency Summit held in San Francisco that BTC and ETH are not securities. Nevertheless, many ICO tokens fall under the securities category.
So far, only BTC and ETH have received approval and recognition of the U.S. regulatory authority as a “non-securities asset.”
Since July 2018, the SEC has investigated more than ten types of digital assets, one after another, and ruled that they were securities and had to be incorporated into the SEC regulatory system. It prosecuted and punished those who had contravened the issuance and trading requirements of the securities laws.
Although there are still many digital assets that have yet to be characterised as “securities”, it is extremely difficult to be characterised as a “non-securities asset” based on the evaluation criteria announced by the SEC. As the SEC’s spokesperson has reiterated many times, they believe the majority of ICO tokens are securities.
Under the stipulated requirements of the SEC, Coinbase, a leading U.S. exchange, has withdrawn a batch of digital assets. The assets withdrawn included digital assets that had been characterised as “securities” as well as those that have high risks of being characterised as “securities.” However, it is worth noting that although the risk to be characterised as “securities” for more than ten types of digital assets, which have not been explicitly required by SEC to be withdrawn, is relatively small, they are not entirely safe. With the further escalation of the SEC’s investigations, they could still be characterised as securities and be held accountable for violating their responsibilities. However, this requires further guidance from the SEC.
*Coinbase’s 14 types of digital assets that have yet to be requested for withdrawal
Poloniex announced on 16 May that it would stop providing services for nine digital assets, including Ardor (ARDR), Bytecoin (BCN), etc. under the compliance guidelines of the SEC. On 7 June, Bittrex also announced that it would stop providing trading services to U.S. users for 32 digital assets. The action of the SEC on its regulatory guidance was further reinforced apparently.
In fact, it is not the first time that these two exchanges have withdrawn digital assets under regulatory requirements. Since the rapid development of digital assets driven by ICO in 2017, Poloniex and Bittrex were once leading exchanges for ICO tokens, providing comprehensive trading services for digital assets. However, after the SEC reiterated its compliance requirements, Poloniex and Bittrex have withdrawn a considerable amount of assets in the past year to meet the compliance requirements.
In conclusion, the takeaways that we have got are as follows: Under the existing U.S. regulatory requirements of digital assets, after obtaining the basic entry licences (MSB, MTL), exchanges could either choose the “compliant asset” solution of Coinbase and only list a small number of digital assets that do not have apparent characteristics of a security, and at all times prepare to withdraw any asset later characterised as “securities” by the SECs; or choose to be like OKEx and Huobi and make it clear they would “not provide services to any U.S. users” at the start.
Binance has been providing a large number of digital assets that have characteristics of a security to U.S users without a U.S. securities exchange licence, so it has already contravened the SEC regulatory requirements.
On top of that, it is also worth noting that the rapid development of Binance has been achieved precisely through the behaviours of “contrary to regulations” and “committing crimes.” Amid the blocking of several pioneering exchanges, such as OKCoin, Huobi, etc. providing services to Chinese users in the Chinese market under new laws from the regulatory authorities, Binance leapfrogged the competition and began to dominate the Chinese market. Similarly, Binance’s rapid growth in the U.S. market is mainly due to its domination of the traffic of digital assets withdrawn by Poloniex and Bittrex. One can say that Binance not only has weak awareness of compliance issues, but it is also indeed “playing with fire” with the U.S. regulators.
In April 2018, the New York State Office of Attorney General (OAG) requested 13 digital asset exchanges, including Binance, to prepare for investigations, indicating it would initiate an investigation in relations to company ownership, leadership, operating conditions, service terms, trading volume, relationships with financial institutions, etc. Many exchanges, including Gemini, Bittrex, Poloniex, BitFlyer, Bitfinex, and so on, proactively acknowledged and replied in the first instance upon receipt of the investigation notice. However, Binance had hardly any action.
Binance has been illegally operating in the U.S. for almost two years. It has not yet fulfilled the FinCEN and MSB registration requirements. Moreover, it has also neglected the SEC announcements and OAG investigation summons on several occasions. The ultimate announcement of exiting the U.S. market may be due to the tremendous pressure imposed by the U.S. regulators.
In fact, the SEC executives have recently stressed that “exchanges of IEO in the U.S. market are facing legal risks and the SEC would soon crack down on these illegal activities” on numerous occasions. These were clear indications of imposing pressure on Binance.
Regarding the SEC’s rulings on illegal digital asset exchanges, EtherDelta and investment management platform, Crypto Asset Management, it may not be easy for Binance to “fully exit” from the U.S. market. It may be faced with a hefty penalty. Once there are any compensation claims by the U.S. users for losses incurred in the trading of assets at Binance, it would be dragged into a difficult compensation dilemma. It would undoubtedly be a double blow for Binance that has just been held accountable for the losses incurred in a theft of 7,000 BTC.
Coincidentally, Binance was tossed out of Japan because of compliance issues. In March 2018, the Financial Services Agency of Japan officially issued a stern warning to Binance, which was boldly providing services to Japanese users without registering for a digital asset exchange licence in Japan. Binance was forced to relocate to Malta instead. Binance may have to bear hefty penalties arising from challenging the compliance requirements after it had lost important markets due to consecutive compliance issues.
The rise of Binance was attributed to its bold and valiant style, grasping the opportunity created in the vacuum period of government regulation, breaking compliance requirements and rapidly dominating the market to obtain user traffic. For a while, it gained considerable advantages in the early, barbaric growth stage of the industry. Nonetheless, under the increasingly comprehensive regulatory compliance system for global digital asset markets, Binance, which has constantly been “evading regulation” and “resisting supervision” would undoubtedly face enormous survival challenges, notwithstanding that it would lose far more than 50 per cent of the market share.

When we launched the Redeeem affiliate program we did a lot of research on other crypto companies, and what their affiliate policies were. We studied the many structures to an affiliate program, and we made a list of the top 10 crypto affiliate programs.
A few popular affiliate program models:
  1. Recurring Revenue Model - you have a unique URL affiliate link, and when you send it to people their account is linked to yours, and you get a percentage of whatever they spend or trade during their time. Sometimes this can be time limited (for 30 days), but typically goes for the life of the person you refer. Typically referral fees are taken from the company, so the company might advertise as 30% of Company's revenue, or it may say 1% of money spent on the platform.
  2. Initial payout Model - this is the most popular and simplest model for paying affiliates. A simple pay per sign up, typically between $5 and $15 per sign up you get. However, rarely will you get paid just for the signup, instead the new user must complete some "engaging action" on the website - a purchase, a trade, or a post.
  3. Multi-tiered Revenue Model - this is an extrapolated model from the recurring revenue model, where there are multiple tiers, or levels, so you get paid for the people who get referred by the people you refer. Typically it's a smaller % for the indirect tier, since you didn't do any work, but it does incentivize people to find the power players and refer them to the website.

batching in Bitcoin

On May 6th, 2017, Bitcoin hit an all-time high in transactions processed on the network in a single day: it moved 375,000 transactions which accounted for a nominal output of about $2.5b. Average fees on the Bitcoin network had climbed over a dollar for the first time a couple days prior. And they kept climbing: by early June average fees hit an eye-watering $5.66. This was quite unprecedented. In the three-year period from Jan. 1 2014 to Jan. 1 2017, per-transaction fees had never exceeded 31 cents on a weekly average. And the hits kept coming. Before 2017 was over, average fees would top out at $48 on a weekly basis. When the crypto-recession set in, transaction count collapsed and fees crept back below $1.
During the most feverish days of the Bitcoin run-up, when normal users found themselves with balances that would cost more to send than they were worth, cries for batching — the aggregation of many outputs into a single transaction — grew louder than ever. David Harding had written a blog post on the cost-savings of batching at the end of August and it was reposted to the Bitcoin subreddit on a daily basis.
The idea was simple: for entities sending many transactions at once, clustering outputs into a single transaction was more space- (and cost-) efficient, because each transaction has a fixed data overhead. David found that if you combined 10 payments into one transaction, rather than sending them individually, you could save 75% of the block space. Essentially, batching is one way to pack as many transactions as possible into the finite block space available on Bitcoin.
When fees started climbing in mid-2017, users began to scrutinize the behavior of heavy users of the Bitcoin blockchain, to determine whether they were using block space efficiently. By and large, they were not — and an informal lobbying campaign began, in which these major users — principally exchanges — were asked to start batching transactions and be good stewards of the scarce block space at their disposal. Some exchanges had been batching for years, others relented and implemented it. The question faded from view after Bitcoin’s price collapsed in Q1 2018 from roughly $19,000 to $6000, and transaction load — and hence average fee — dropped off.
But we remained curious. A common refrain, during the collapse in on-chain usage, was that transaction count was an obfuscated method of apprehending actual usage. The idea was that transactions could encode an arbitrarily large (within reason) number of payments, and so if batching had become more and more prevalent, those payments were still occurring, just under a regime of fewer transactions.

“hmmm”
Some sites popped up to report outputs and payments per day rather than transactions, seemingly bristling at the coverage of declining transaction count. However, no one conducted an analysis of the changing relationship between transaction count and outputs or payments. We took it upon ourselves to find out.
Table Of Contents:
Introduction to batching
A timeline
Analysis
Conclusion
Bonus content: UTXO consolidation
  1. Introduction to batching
Bitcoin uses a UTXO model, which stands for Unspent Transaction Output. In comparison, Ripple and Ethereum use an account/balance model. In bitcoin, a user has no balances, only UTXOs that they control. If they want to transfer money to someone else, their wallet selects one or more UTXOs as inputs that in sum need to add up to the amount they want to transfer. The desired amount then goes to the recipient, which is called the output, and the difference goes back to the sender, which is called change output. Each output can carry a virtually unlimited amount of value in the form of satoshis. A satoshi is a unit representing a one-hundred-millionth of a Bitcoin. This is very similar to a physical wallet full of different denominations of bills. If you’re buying a snack for $2.50 and only have a $5, you don’t hand the cashier half of your 5 dollar bill — you give him the 5 and receive some change instead.
Unknown to some, there is no hardcoded limit to the number of transactions that can fit in a block. Instead, each transaction has a certain size in megabytes and constitutes an economic incentive for miners to include it in their block. Because miners have limited space of 2 MB to sell to transactors, larger transactions (in size, not bitcoin!) will need to pay higher fees to be included. Additionally, each transaction can have a virtually unlimited number of inputs or outputs — the record stands at transactions with 20,000 inputs and 13,107 outputs.
So each transaction has at least one input and at one output, but often more, as well as some additional boilerplate stuff. Most of that space is taken up by the input (often 60% or more, because of the signature that proves they really belong to the sender), while the output(s) account for 15–30%. In order to keep transactions as small as possible and save fees, Bitcoin users have two major choices:
Use as few inputs as possible. In order to minimize inputs, you can periodically send your smaller UTXOs to yourself in times when fees are very low, getting one large UTXO back. That is called UTXO consolidation or consolidating your inputs.
Users who frequently make transfers (especially within the same block) can include an almost unlimited amount of outputs (to different people!) in the same transaction. That is called transaction batching. A typical single output transaction takes up 230 bytes, while a two output transaction only takes up 260 bytes, instead of 460 if you were to send them individually.
This is something that many casual commentators overlook when comparing Bitcoin with other payment systems — a Bitcoin transaction can aggregate thousands of individual economic transfers! It’s important to recognize this, as it is the source of a great deal of misunderstanding and mistaken analysis.
We’ve never encountered a common definition of a batched transaction — so for the purposes of this study we define it in the loosest possible sense: a transaction with three or more outputs. Commonly, batching is understood as an activity undertaken primarily by mining pools or exchanges who can trade off immediacy for efficiency. It is rare that a normal bitcoin user would have cause to batch, and indeed most wallets make it difficult to impossible to construct batched transactions. For everyday purposes, normal bitcoiners will likely not go to the additional effort of batching transactions.
We set the threshold at three for simplicity’s sake — a normal unbatched transaction will have one transactional output and one change output — but the typical major batched transaction from an exchange will have dozens if not hundreds of outputs. For this reason we are careful to provide data on various different batch sizes, so we could determine the prevalence of three-output transactions and colossal, 100-output ones.
We find it helpful to think of a Bitcoin transaction as a mail truck full of boxes. Each truck (transaction) contains boxes (outputs), each of contains some number of letters (satoshis). So when you’re looking at transaction count as a measure of the performance and economic throughput of the Bitcoin network, it’s a bit like counting mail trucks to discern how many letters are being sent on a given day, even though the number of letters can vary wildly. The truck analogy also makes it clear why many see Bitcoin as a settlement layer in the future — just as mail trucks aren’t dispatched until they’re full, some envision that the same will ultimately be the case for Bitcoin.

Batching
  1. A timeline
So what actually happened in the last six months? Let’s look at some data. Daily transactions on the Bitcoin network rose steadily until about May 2017, when average fees hit about $4. This precipitated the first collapse in usage. Then began a series of feedback loops over the next six months in which transaction load grew, fees grew to match, and transactions dropped off. This cycle repeated itself five times over the latter half of 2017.

more like this on coinmetrics.io
The solid red line in the above chart is fees in BTC terms (not USD) and the shaded red area is daily transaction count. You can see the cycle of transaction load precipitating higher fees which in turn cause a reduction in usage. It repeats itself five or six times before the detente in spring 2018. The most notable period was the December-January fee crisis, but fees were actually fairly typical in BTC terms — the rising BTC price in USD however meant that USD fees hit extreme figures.
In mid-November when fees hit double digits in USD terms, users began a concerted campaign to convince exchanges to be better stewards of block space. Both Segwit and batching were held up as meaningful approaches to maximize the compression of Bitcoin transactions into the finite block space available. Data on when exchanges began batching is sparse, but we collected information where it was available into a chart summarizing when exchanges began batching.

Batching adoption at selected exchanges
We’re ignoring Segwit adoption by exchanges in this analysis; as far as batching is concerned, the campaign to get exchanges to batch appears to have persuaded Bitfinex, Binance, and Shapeshift to batch. Coinbase/GDAX have stated their intention to begin batching, although they haven’t managed to integrate it yet. As far as we can tell, Gemini hasn’t mentioned batching, although we have some mixed evidence that they may have begun recently. If you know about the status of batching on Gemini or other major exchanges please get in touch.
So some exchanges have been batching all along, and some have never bothered at all. Did the subset of exchanges who flipped the switch materially affect the prevalence of batched transactions? Let’s find out.
  1. Analysis
3.1 How common is batching?
We measured the prevalence of batching in three different ways, by transaction count, by output value and by output count.

The tl;dr.
Batching accounts for roughly 12% of all transactions, 40% of all outputs, and 30–60% of all raw BTC output value. Not bad.
3.2 Have batched transactions become more common over time?
From the chart in 3.1, we can already see a small, but steady uptrend in all three metrics, but we want to dig a little deeper. So we first looked at the relationship of payments (all outputs that actually pay someone, so total outputs minus change outputs) and transactions.

More at transactionfee.info/charts
The first thing that becomes obvious is that the popular narrative — that the drop in transactions was caused by an increase in batching — is not the case; payments dropped by roughly the same proportion as well.
Dividing payment count by transaction count gives us some insight into the relationship between the two.

In our analysis we want to zoom into the time frame between November 2017 and today, and we can see that payments per transactions have actually been rallying, from 1.5 payments per transaction in early 2017 to almost two today.
3.3 What are popular batch sizes?
In this next part, we will look at batch sizes to see which are most popular. To determine which transactions were batched, we downloaded a dataset of all transactions on the Bitcoin network between November 2017 and May 2018from Blockchair.
We picked that period because the fee crisis really got started in mid-November, and with it, the demands for exchanges to batch. So we wanted to capture the effect of exchanges starting to batch. Naturally a bigger sample would have been more instructive, but we were constrained in our resources, so we began with the six month sample.
We grouped transactions into “batched” and “unbatched” groups with batched transactions being those with three or more outputs.

We then divided batched transactions into roughly equal groups on the basis of how much total output in BTC they had accounted for in the six-month period. We didn’t select the batch sizes manually — we picked batch sizes that would split the sample into equal parts on the basis of transaction value. Here’s what we ended up with:

All of the batch buckets have just about the same fraction of total BTC output over the period, but they account for radically different transaction and output counts over the period. Notice that there were only 183,108 “extra large” batches (with 41 or more outputs) in the six-month period, but between them there were 23m outputs and 30m BTC worth of value transmitted.
Note that output value in this context refers to the raw or unadjusted figure — it would have been prohibitively difficult for us to adjust output for change or mixers, so we’re using the “naive” estimate.
Let’s look at how many transactions various batch sizes accounted for in the sample period:


Batched transactions steadily increased relative to unbatched ones, although the biggest fraction is the small batch with between 3 and 5 outputs. The story for output counts is a bit more illuminating. Even though batched transactions are a relatively small fraction of overall transaction count, they contain a meaningful number of overall outputs. Let’s see how it breaks down:


Lastly, let’s look at output value. Here we see that batched transactions represent a significant fraction of value transmitted on Bitcoin.


As we can see, even though batched transactions make up an average of only 12% of all transactions, they move between 30%-60% of all Bitcoins, at peak times even 70%. We think this is quite remarkable. Keep in mind, however that the ‘total output’ figure has not been altered to account for change outputs, mixers, or self-churn; that is, it is the raw and unadjusted figure. The total output value is therefore not an ideal approximation of economic volume on the Bitcoin network.
3.4 Has transaction count become an unreliable measure of Bitcoin’s usage because of batching?
Yes. We strongly encourage any analysts, investors, journalists, and developers to look past mere transaction count from now on. The default measure of Bitcoin’s performance should be “payments per day” rather than transaction count. This also makes Bitcoin more comparable with other UTXO chains. They generally have significantly variable payments-per-transaction ratios, so just using payments standardizes that. (Stay tuned: Coinmetrics will be rolling out tools to facilitate this very soon.)
More generally, we think that the economic value transmitted on the network is its most fundamental characteristic. Both the naive and the adjusted figures deserve to be considered. Adjusting raw output value is still more art than science, and best practices are still being developed. Again, Coinmetrics is actively developing open-source tools to make these adjustments available.
  1. Conclusion
We started by revisiting the past year in Bitcoin and showed that while the mempool was congested, the community started looking for ways to use the blockspace more efficiently. Attention quickly fell on batching, the practice of combining multiple outputs into a single transaction, for heavy users. We showed how batching works on a technical level and when different exchanges started implementing the technique.
Today, around 12% of all transactions on the Bitcoin network are batched, and these account for about 40% of all outputs and between 30–60% of all transactional value. The fact such that a small set of transactions carries so much economic weight makes us hopeful that Bitcoin still has a lot of room to scale on the base layer, especially if usage trends continue.
Lastly, it’s worth noting that the increase in batching on the Bitcoin network may not be entirely due to deliberate action by exchanges, but rather a function of its recessionary behavior in the last few months. Since batching is generally done by large industrial players like exchanges, mixers, payment processors, and mining pools, and unbatched transactions are generally made by normal individuals, the batched/unbatched ratio is also a strong proxy for how much average users are using Bitcoin. Since the collapse in price, it is quite possible that individual usage of Bitcoin decreased while “industrial” usage remained strong. This is speculation, but one explanation for what happened.
Alternatively, the industrial players appear to be taking their role as stewards of the scarce block space more seriously. This is a significant boon to the network, and a nontrivial development in its history. If a culture of parsimony can be encouraged, Bitcoin will be able to compress more data into its block space and everyday users will continue to be able to run nodes for the foreseeable future. We view this as a very positive development. Members of the Bitcoin community that lobbied exchanges to add support for Segwit and batching should be proud of themselves.
  1. Bonus content: UTXO consolidation
Remember that we said that a second way to systematically save transaction fees in the Bitcoin network was to consolidate your UTXOs when fees were low? Looking at the relationship between input count and output count allows us to spot such consolidation phases quite well.

Typically, inputs and outputs move together. When the network is stressed, they decouple. If you look at the above chart carefully, you’ll notice that when transactions are elevated (and block space is at a premium), outputs outpace inputs — look at the gaps in May and December 2017. However, prolonged activity always results in fragmented UTXO sets and wallets full of dust, which need to be consolidated. For this, users often wait until pressure on the network has decreased and fees are lower. Thus, after transactions decrease, inputs become more common than outputs. You can see this clearly in February/March 2017.

Here we’ve taken the ratio of inputs to outputs (which have been smoothed on a trailing 7 day basis). When the ratio is higher, there are more inputs than outputs on that day, and vice versa. You can clearly see the spam attack in summer 2015 in which thousands (possibly millions) of outputs were created and then consolidated. Once the ratio spikes upwards, that’s consolidation. The spike in February 2018 after the six weeks of high fees in December 2017 was the most pronounced sigh of relief in Bitcoin’s history; the largest ever departure from the in/out ratio norm. There were a huge number of UTXOs to be consolidated.
It’s also interesting to note where inputs and outputs cluster. Here we have histograms of transactions with large numbers of inputs or outputs. Unsurprisingly, round numbers are common which shows that exchanges don’t publish a transaction every, say, two minutes, but instead wait for 100 or 200 outputs to queue up and then publish their transaction. Curiously, 200-input transactions were more popular than 100-input transactions in the period.


We ran into more curiosities when researching this piece, but we’ll leave those for another time.
Future work on batching might focus on:
Determining batched transactions as a portion of (adjusted) economic rather than raw volume
Looking at the behavior of specific exchanges with regards to batching
Investigating how much space and fees could be saved if major exchanges were batching transactions
Lastly, we encourage everyone to run their transactions through the service at transactionfee.info to assess the efficiency of their transactions and determine whether exchanges are being good stewards of the block space.
Update 31.05.2018
Antoine Le Calvez has created a series of live-updated charts to track batching and batch sizes, which you can find here.
We’d like to thank 0xB10C for their generous assistance with datasets and advice, the people at Blockchair for providing the core datasets, and David A. Harding for writing the initial piece and answering our questions.

Are companies like Chainalysis good for crypto?

There was a post about Binance teaming up with Chainalysis where I commented my concerns but the post didn't get enough traction. So I want to share some concerns and instigate some discussion around the topic.

Who?

Chainalysis is a company that leases investigation software to companies and governments to track and identify the users of cryptocurrencies like Bitcoin.
I can understand the positives to something like this which may be useful for tracking criminals and ensuring compliance. However, where do we draw the line? For a lot of people this goes against the fundamental principles of cryptocurrency.
I'm not saying this company or their software shouldn't exist, but I don't think we should support them or anything like them unless their software was to be used for research purposes to improve the sector. The software or act itself isn't bad per se rather the intention and circumstances around them are perturbing.
I have grave concerns that powerful groups and individuals - whether government, law enforcement or corporations can contract companies like Chainalysis to punish individuals even for legal activities.

Close Connections

Not to mention a lot of these companies are interconnected and invested in each other, which isn't a negative itself - but may raise red flags.
E.g. Digital Currency Group is invested in Chainalysis, and also has financial positions in Blockstream, Bitpay, Bitso, Bitwala, Brave, Circle, Civic, Coinbase, CoinDesk, CoinJar, Decent, Kraken, Ledger, Luno, Parity, Purse, Ripio, Ripple, ShapeShift, ZCash etc.
Funders Club which invests in DCG, which invests in Chainalysis is also invested in Coinbase, Slack, Chainalysis, Gitlab, KickPay and dozens and dozens more.
Techstars is also partnered with Target, IBM, Amazon Alexa, Ford, Barclays, Bosch and many other big companies.
I know this is a relatively emerging space, and it's not uncommon for start-up accelerators, VC and Angel Funds, and Investment companies to be few in number and willing to shell out the big bucks. However I do hope the trend reverses while crypto furthers into mainstream view and is adopted more regularly which will pave the way for great competition for funding seed rounds or even more distributed crowd-funding outcomes.
In a world where everyone and everything is connected, surely this is not what we had in mind?

"“It was a bright day in April, and the clocks were striking thirteen.”"

Chainalysis has services for governments to "Leverage pattern recognition, machine learning and open source references to identify suspicious activity across billions of cryptocurrency transactions." and imagine if authoritarian governments use it to track legitimate uses. Or a country where crypto is illegal, the government can use Chainalysis (who could partner with exchanges) to track who is using it and punish them. I hope they don't work with governments like China, Iran, Egypt, Saudi Arabia, Pakistan, Syria, North Korea, Myanmar, Indonesia, Syria, Chad etc where either using Bitcoin is illegal or they're authoritarian, corrupt regimes. Most of the above aren't even sanctioned by OFAC.
Imagine the Chinese government using this on their citizens given their corruption, random kidnappings and threats. Even the former Chief of Interpol wasn't safe. Or the Egypt Government sentencing an activist for 2 years for merely publishing a critical post on social media. Or activists getting charged with "contact with foreign entities with the aim of undermining the country’s stability and social fabric” for campaigning in Saudi Arabia.

IRS - The New Spooks?

The IRS also has a contract with Chainalysis to identify users and link them to transactions.
Here's a letter from a Chainalysis Co-Founder sent to the IRS, saying they have information on 25% of all Bitcoin addresses, and that was in, or before August 2017.
Transactions in Bitcoin are made with pseudonyms, which need to be tied to real world identities in order to gain insights about the parties involved in a transaction and their purpose. Our tool has information on 25 per cent of all Bitcoin addresses, which account for approximately 50 per cent of all the Bitcoin activity. We additionally have over 4 million tags on Bitcoin addresses that we have scraped from web forums and leaked data sources including dark market forums and Mt Gox deposit and withdrawal information.
Source: Fortune
It's scary how they use the word "need" and how much info they have "tagged."
Here's a document showing the contract between Chainalysis and the IRS.
The contract began during November 2015, where the first invoice amounted to $13,188 for a 12 month license to use Chainalysis' Reactor Investigator software.
What do you think? Are my fears valid? Will this be used against us in the future?

Tron: Rising Dragon in blockchain

Have you heard anything about Alibaba, Jack Ma, Tim Draper, Ripple, JP Morgan? ..
Why am I asking this? Recently I discovered an interesting blockchain project from China. Since I have just returned from China, where I promoted innovative technologies, I was amazed by the scale of the changes taking place in the country and now my focus is primarily on this market.
So, the project is called Tron (www.tronlab.com) and it has an ambitious goal that can not be described in two words. I'll try to list:
1) to replace game currencies with the project's crypto currency - Tronix (TRX). Unlike gaming currencies, this currency will be "real", it has real market value. What is the advantage? According to the idea, all projects connected to the Tron ecosystem will use the common currency Tronix or tokens based on the Tron protocol, which can be freely exchanged for Tronix (TRX). This will allow you to freely move assets between different games and applications.
Imagine, you played in Call of Duty, bought there weapons, then some amount left. Later you decide to play Fifa 201x. Move the existing TRX from Call of Duty to Fifa and buy Messi ;) Then go to the social network and buy a virtual gift to someone for the same TRX, open the online cinema and pay for the movie... And all this quickly, safely, conveniently.
2) integrate the TRX crypto currency into the online entertainment industry, which includes not only games, but also social networks, dating sites, etc. This will allow you to enter the premium group, vote for your favorite entries, present virtual gifts. And these are not just plans, but a working model. The first application, which integrates the TRX crypto currency, is Peiwo with an audience of 10 million users. For comparison, according to the evaluation of experts there are about 20 million Bitcoin owners in the world.
3) use its own mainnet blockchain and protocol for the online entertainment industry. At the moment, the TRX crypto currency is a token on the ERC20 protocol. What will it give? Companies will be able to conduct ICO on the basis of the Tron platform and protocol, which will lead to an increase in the value of TRX's internal crypto currency. One of the main disadvantages of Ethereum is the lack of a hard cap, that is why the system requires constant external funding to maintain the value of the ETH crypto currency. At the same time, the TRX has the same advantages as the ETH but has a hard cap of 100 000 000 000 TRX, with a circulation supply of 65 000 000 000. Many investors in crypto-currencies are concerned about such high circulation supply, but this has its advantages. First, the online games market alone exceeds 100 billion dollars. And this is only a small part of the online entertainment market. For example, in China I was surprised to see how pretty Chinese woman earned more than $ 50 in the form of tips just for eating her dinner on the air in the video-streaming app... And gamers who demonstrate in real time how to play DOTa earn several thousand dollars per month.
Thus, such a circulation supply even with the current development of online entertainment will quickly disperse and there will soon be an increased demand for TRX, which will lead to a steady increase in the price of TRX. For example, at the time of writing, TRX costs about $ 0.0024 (0.0000082ETH). If each user of the Peiwo application purchases 6500 TRX (which is only $ 15.6), then there will already be a deficit of tokens. But most importantly, among investors there are such people as Binshen Tang, the owner of the game Clash of Kings with an audience of 40 000 000 people.
Secondly, there are rumors that the Chinese authorities are considering the prohibition of buying and selling the fractions of cryptocurrencies, so you can not buy 0.5 BTC, but only 1, 2 ... BTC to limit the circulation of crypto-currencies. Such circulation supply of TRX will allow free trade on exchanges with these restrictions. In addition, it will allow you to carry out micropayments, such as watching a few minutes of a movie and pay some cents in TRX.
4) create a decentralized data warehouse based on p2p technologies. This means that the content will be the property of authors, not for example of such services as Facebook, Youtube or Google. In other words, users will pay to the authors directly. To date, the authors receive small earnings from the sale of advertising by these services. In addition, it will ensure the constant availability, permanence and reliability of the information, as it will be stored in the blockchain.
My experience of work with innovative technologies showed that the most important thing in the success of the project is his team. And with this, Tron is all right.
CEO of Tron Foundation is Justin Sun, the former representative of Bitcoin settlement platform Ripple in China. Ripple is now the third cryptocurrency by market cap after Bitcoin and Ethereum. It is used for transactions between banks, like SWIFT.
He was awarded by the next titles:
He founded Peiwo, an app aspiring to become China's Snapchat.
Justin Sun was the student of Jack Ma (Alibaba) at Hupan University. Now he is in the Tim Draper’s University.
Recently to a team of more than 60 people, including experts in p2p and blockchain technologies, joined the senior expert Lucien Chen from Alibaba and Tencent (Wechat app).
So, what about investors? Among them are:
Separately, it should be noted that Justin Sun is a protégé of Jack Ma and teaches a course about blockchain technology at his university. In addition, Jack Ma in his recent interview noted that in the future the society should be healthy and happy. Entertainment brings happiness, so it will be part of Alibaba's business.
There are also rumors that Tim Draper invested in Tron. Tim Draper was one of the first to invest in Tesla, Skype, Baidu (Chinese Google).
Lately Justin Sun tweeted that Fund that supported Ripple and some Hedge Funds invested in Tron Foundation.
And some background information.
ICO from Tron passed in several stages from the second half of August to the beginning of September. The price of 1 TRX during the ICO period was 0.00000488 ETH.
A few interesting facts about the ICO Tron. The stage that was held at the Binance exchange was successfully completed in 39 seconds!!! This heated the interest of investors and at the next stage, which was conducted on another site, the desire of investors to get tokens as quickly as possible led to a system’s crash, such a powerful was "ddos attack". In total, according to preliminary estimates, during the ICO about $ 60 million was raised.
Total supply of TRX is 100 000 000 000, circulation supply is 65 000 000 000. The number of decimals is 6. By coin market cap at present TRX is between the 30th and 40th place among all cryptocurrencies.
At the time of writing, TRX traded on the exchanges HitBTC, Liqui, Qryptos, EtherDelta. Some more exchanges on the way, one of which is Korean and another is Australian coolcoin.com. To see TRX in Etherdelta you have to choose to Add custom token and fill the next data:
Address: 0xf230b790E05390FC8295F4d3F60332c93Bed42e2
Token Symbol: TRX
Decimals: 6
And the most pleasant thing is, until October 30, 2017, you can still buy TRX to get a free 10% airdrop after this date.

Navigating Bitcoin, Ethereum, XRP: How Google Is Quietly Making Blockchains Searchable

Navigating Bitcoin, Ethereum, XRP: How Google Is Quietly Making Blockchains Searchable
It’s a balmy 80 degrees on a mid-December day in Singapore, and something is puzzling Allen Day, a 41-year-old data scientist. Using the tools he has developed at Google, he can see a mysterious concerted usage of artificial intelligence on the blockchain for Ethereum. Ether is the world’s third-largest cryptocurrency (after bitcoin and XRP), and it still sports a market cap of some $11 billion despite losing 83% of its value in 2018. Peering into its blockchain—the distributed database of transactions underpinning the cryptocurrency—Day detects a “whole bunch” of “autonomous agents” moving funds around “in an automated fashion.” While he doesn’t yet know who has created the AI, he suspects they could be the agents of cryptocurrency exchanges trading among themselves in order to artificially inflate ether’s price.
“It’s not really just single agents doing things on their own,” Day says from Google’s Asia-Pacific headquarters. “They’re forming with other agents to have some larger group effect.”
Day’s official title is senior developer advocate for Google Cloud, but he describes his role as “customer zero” for the company’s cloud computing efforts. As such it’s his job to anticipate demand before a product even exists, and he thinks making the blockchain more accessible is the next big thing. Just as Google enabled (and ultimately profited) from making the internet more usable 20 years ago, its next billions may come from shining a bright light on blockchains. If Day is successful, the world will know whether blockchain’s real usage is living up to its hype.
Danish researcher Thomas Silkjaer is using Google's BigQuery to map publicly available information about XRP cryptocurrency addresses. The craters represent some of cryptocurrency's largest exchanges.
Last year Day and a small team of open-source developers quietly began loading data for the entire Bitcoin and Ethereum blockchains into Google’s big-data analytics platform, BigQuery. Then, with the help of lead developer Evgeny Medvedev, he created a suite of sophisticated software to search the data.
In spite of a total lack of publicity, word of the project spread quickly among crypto-minded coders. In the past year, more than 500 projects were created using the new tools, trying to do everything from predicting the price of bitcoin to analyzing wealth disparity among ether holders.
When it comes to cloud computing, Google is far behind Amazon and Microsoft. Last year Google pocketed an estimated $3 billion in revenue from cloud ser­vices. Amazon and Microsoft, meanwhile, generated about $27 billion and $10 billion, respectively.
Day is hoping that his project, known as Blockchain ETL (extract, transform, load), will help even the playing field. But even here Google is trying to catch up. Amazon entered blockchain in a big way in 2018 with a suite of tools for building and managing distributed ledgers. Microsoft got into the space in 2015, when it released tools for Ethereum’s blockchain. It now hosts a range of services as part of its Azure Blockchain Workbench. But while Amazon and Microsoft are focusing on making it easier to build blockchain apps, Day is focusing on exposing how blockchains are actually being used, and by whom.
“In the future, moving more economic activity on chain won’t just require a consensus level of trust,” says Day, referring to the core validating mechanism of blockchain technology. “It will require having some trust in knowing about who it is you’re actually interacting with.” In other words, if blockchain is to go mainstream, some of its beloved anonymity features will have to be abandoned.
A native of Placer County, California, Day got his first computer at the age of 5 and a few years later started writing simple programs. A fascination with volcanoes and dinosaurs turned his interest to life sciences, and he ultimately graduated from the University of Oregon with a dual degree in biology and Mandarin in 2000. From there he headed to UCLA to pursue a doctorate in human genetics and helped build a computer program to browse the genome.
It was at UCLA where Day began relying on distributed computing, a concept that is core to blockchains, which store their data on a large network of individual computers. In the early 2000s Day needed to analyze the massive amounts of data that make up the human genome. To solve this problem he hooked many small computers together, vastly increasing their power.
“Distributed-systems technology has been in my tool kit for a while,” Day says. “I could see there were interesting characteristics of blockchains that could run a global supercomputer.”
Hired in 2016 to work in the health and bio­informatics areas of Google, Day segued to blockchains, the hottest distributed-computing effort on the planet. But the talents he had honed—sequencing genomes for infectious diseases in real time and using AI to increase rice yields—were not easily applied to decoding blockchain.
Before Day and Medvedev released their tools, just searching a blockchain required specialized software called “block explorers,” which let users hunt only for specific transactions, each labeled with a unique tangle of 26-plus alphanumeric characters. Google’s Blockchain ETL, by contrast, lets users make more generalized searches of entire ecosystems of transactions.
To demonstrate how customers could use Blockchain ETL to make improvements to the crypto economy, Day has used his tools to examine the so-called hard fork, or an irrevocable split in a blockchain database, that created a new cryptocurrency—bitcoin cash—from bitcoin in the summer of 2017.
Google Cloud developer advocate Allen Day presents his early cryptocurrency work at Google's Asia Pacific headquarters in Singapore in August 2018. DORJEE SUN / PERLIN
This particular split was the result of a Hatfield and McCoy “war” within the bitcoin community between a group who wanted to leave bitcoin as it was and another who wanted to develop a currency that, like cash, was cheaper and faster to use for small payments. Using Google’s BigQuery, Day discovered that bitcoin cash, rather than increasing so-called micro-transactions, as the defecting developers claimed, was actually being hoarded among big holders of bitcoin cash. “I’m very interested to quantify what’s happening so that we can see where the legitimate use cases are for blockchain,” Day says. “Then we can move to the next use case and develop out what these technologies are really appropriate for.”
Day’s work is inspiring others. Tomasz Kolinko is a Warsaw-based programmer and the creator of a service that analyzes smart contracts, a feature of certain blockchains that is designed to transparently enforce contractual obligations like collateralized loans but with less reliance on third parties, like lawyers. Kolinko was frustrated with his blockchain queries.
In December, Kolinko met Day at a hackathon in Singapore. Within a month of the meeting, Kolinko was using Google’s tools to search for a smart contract feature called a “selfdestruct,” designed to limit a contract’s life span. Using his own software in conjunction with Day’s, Kolinko took 23 seconds to search 1.2 million smart contracts—something that would have taken hours before. The result: Almost 700 of them had left open a selfdestruct feature that would let anyone instantly kill the smart contract, whether that person was authorized or not. “In the past you couldn’t just easily check all the contracts that were using it,” Kolinko says. “This tool is both the most scary and most inspiring I’ve ever built.”
Day is now expanding beyond bitcoin and ethereum. Litecoin, zcash, dash, bitcoin cash, ethereum classic and dogecoin are being added to BigQuery. Independent developers are loading their own crypto data sets on Google. Last August, a Dutch developer named Wietse Wind uploaded the entire 400 gigabytes of transaction data from Ripple’s XRP blockchain, another popular cryptocurrency, into BigQuery. Wind’s data, which he updates every 15 minutes, prompted a Danish designer named Thomas Silkjaer to create a heat map of crypto flows. The resulting colorful orb reveals at a glance more than a million crypto wallets, including big ex­changes like Binance and London’s crypto debit card startup Wirex, which are neck deep in XRP transactions.
“Google has been a bit of a sleeping giant in blockchain,” says BlockApps CEO Kieren James-Lubin, who is partnering with Google to sell enterprise blockchain apps. In addition to Day’s work, Google has filed numerous patents related to the blockchain, including one in 2018 to use a “lattice” of interoperating blockchains to increase security, a big deal in a world where untold millions of crypto have been stolen by hackers. The company is also pushing its developers to build apps on the Ethereum blockchain, and Google’s venture arm, GV, has made a number of significant investments in crypto startups.
The giant, it seems, is waking up.
