In October, the ArcBlock engineering team’s pace of progress was significantly accelerated, with the release of the beta version of the Developer Console, the Token Flow proof-of-concept version, a top-to-bottom reconstruction of OCAP’s Ethereum data, and the completion of the framework for the construction of the future ABT chain, which will be built on Forge.

ArcBlock was invited to participate in a US government blockchain project, formally became a global technology partner of Amazon Web Services, announced cooperation with LifeID and QuarkChain, participated in important activities organized by the Hyperledger Foundation and the Huazhou Technology Industry Association (WTIA), and developed in conjunction with the Nuggets community.

ArcBlock continues to accumulate substantial cooperation and expansion in the corporate and government markets, and is continuously expanding its influence in the developer community, laying a solid foundation for the ArcBlock platform and blockchain 3.0 ecosystem.

This monthly report is the first to publish a chart generated by the ArcBlock data team which shows ABT-related data analysis on Ethereum, and more data charts which demonstrate analysis through Open Chain Access Protocol will be shared in the future.


Since June, ArcBlock's weekly technical engineering progress has been documented on [GitHub]( A monthly engineering digest can also be found [here](


Front end: Developer Console internal beta release

Developer Console is the prototype of ArcBlock’s developer service console. The functions implemented in the initial version mainly include managing developer identity information, account security settings, ABT ownership certificate, etc.


The Developer Console also contains links to various SDKs, the Starter Project, development tools, code samples and other contents provided by ArcBlock for developers to find what they need and start developing their applications quickly.


Front end: website single sign-in interface, SDK release

We have released universal login and registration pages for all ArcBlock website products, encapsulated reusable user authentication SDKs, and integrated login functions in Playground, Playbook, Developer Console and other applications.


Front-end: POC version of blockchain capital flow analysis tool

ArcBlock’s team released the proof-of-concept version of tools for capital flow analysis and account feature analysis based on public blockchain data, which will be continuously updated in the future.


Front end: Tools for convenient wallet management and message signing below command line

Because the Developer Console supports Metamask and offline signing when verifying a wallet, we have developed, and fully open sourced command line tools for managing wallets and signing messages below the command line: @arcblock/ocap-cli。


Front end: Android and iOS SDK add HMAC request signature support

Developers who register an account in Developer Console, verify ABT ownership, and pass the authentication parameters when requesting OCAP service can enjoy greater QPS and paging quota, and the modification function is supported in the SDK on each side.

Back end: Auth service is connected with web, iOS, Android and SDK

The registration and login of users on the web, iOS and Android terminals, and user authentication, including SDK of each language, are completed through the Auth service. In addition, the Auth service also implements the account quota mechanism based on ABT holdings.

Back end: OCAP service refactoring underlying Ethereum data

In the previous version, we only dealt with ERC20-compatible Ethereum contract transactions. As we gradually build a contract function signature database, we can handle tens of thousands of known signature contract transactions. In October, our main focus at OCAP was on proper data processing and refactoring.

Back end: Forge framework

In October we launched the development of Forge framework with the goal of providing a framework for creating blockchain projects for developers to use. Developers can easily develop a chain of applications by simply focusing on transaction and state processing. The Forge framework is still under development and is expected to be open source by the end of the year. Forge is born out of our proof-of-concept on the ABT chain. Forge and the ABT chain are under synchronous development; the ABT chain will be built on Forge.

Data: ERC20 token product metrics

After supporting ABT's major product metrics (DAU, MAU, retention, holder, price), we extend this support to other ERC20 tokens.


ArcBlock was invited to participate in a U.S. government blockchain project, expanding the possibilities for blockchain in government

In October, ArcBlock, on behalf of the blockchain industry, was invited to participate in a blockchain research project for the United States government, and submitted a project proposal.

ArcBlock has been committed to conducting a deeper and more comprehensive analysis of the data on the blockchain, constantly exploring how to maximize its value. At present, we have set up our own Ethereum node to analyze the data on the chain, including smart contracts, account status, and contract information in the transaction. We’re cleaning up the data, and performing aggregate calculations to input to the cloud database, while backing up on Amazon S3 at the same time. Parsed data can be used for other more systematic analysis, in addition to being queried by users through the OCAP API and GraphQL.

Considering the large amount of data generated on the blockchain and the high speed, we adopted Spark as our main computing tool and demonstrated the analysis results with Python drawing tools. Spark is a generic cluster computing framework that can call multiple machines to perform memory calculations, which greatly improves the efficiency of data analysis. Python's extensive mapping tools give us the flexibility to arrange the various charts because of the complexity of the data types. Below are four charts that we analyzed from ABT-related data on Ethereum, and we will share more in-depth data in the future.


Above is a line chart with ABT prices, number of transactions, and number of participants. Where the blue line represents the price change of ABT, and the green line is the number of daily ABT transactions. It can be seen from the data analysis results that the trading volume of ABT has maintained a relatively stable range.


Through the aggregate calculations, we analyzed the trend chart of the number of ABT holders and superimposed it one the price chart. The orange line shows the number of holders, that is, how many accounts have more than zero ABT. While ABT prices have fluctuated with the market, the overall number of currency holders has remained stable to date.

These two charts are a pie chart analysis of the main holders of ABT currently circulating in the secondary market. The first picture contains exchanges, and the second does not. It can be seen that the largest individual shareholder is address 0 xffbe389a8059aafdf6c88ed1f540e06cca1d8444 account. Its holdings of ABT accounted for 29.8% of all personal holdings.

Media Coverage

On October 25, dozens of media outlets reported on ArcBlock’s partnership with Amazon Web Services.

On October 25, dozens of media, including Sharing Finance, Planet Daily, Chain News, Ear Finance, Deep Chain Finance, CoinVoice, Gyro Finance, Fulcrum Community, Singularity Finance and Gronghui reported that ArcBlock joined the Amazon Web Services Partnership Program, becoming a global technology partner.

On October 12, Rober Mao said, in a retweet of a media article, "Platforms and middleware are driving the maturity of the underlying technology and upper applications. The database age, the Internet age, and the mobile Internet age all had their process... Now it's blockchain's turn. "


As for the launch of the main network, Mao expressed his opinion on October 29 by forwarding a blog post by Chen Tian, Vice President of Research and Development: for ArcBlock, the goal is not only to launch the main network, but to make the main network of any application easier and faster. Many misconceptions and outdated ideas linger in the blockchain community today, such as "mainline online", a very misleading term.


"We have reason to believe that blockchain technology, along with digital currency technology, will become the infrastructure of the whole society in the next 10 years, bringing about radical changes and bringing benefits to all mankind," Mao said on October 31, the 10th anniversary of Mr. Nakamoto's Bitcoin white paper.


Chen Tian also published his own feelings on joining the blockchain movement when retweeting Mao’s commemorative article
