In July, the ArcBlock team entered the state of engineering development and marketing at full speed: in 30 days, ArcBlock's first application, the OCAP Playground, released 20 internal versions. The technical team submitted 206 Pull Requests to GitHub, and the OCAP-based product service was quickly iteratively optimized. Robert Mao, the founder of ArcBlock, along with the marketing team, attended eight events, numerous online sharing and offline roadshow forums, and participated in nine interviews. In the United States, South Korea, Japan, and Vietnam, face-to-face in-depth communication with local developer communities and potential partners has been conducted, laying the foundation for ArcBlock to carry out hackathons and build an ecosystem of developers around the world.

Robert has said that no matter how volatile the market is, ArcBlock will promote the development of its platform according to the established timetable, and will not change the global route promotion plan. He said, "Ever since September of last year, we have been working hard to validate prototypes in the bleak market and write our own white papers over and over again. Good market opportunities are reserved for those who are ready. It is better to do something real than to complain."


OCAP Playground: 20 internal versions in 30 days

ArcBlock's first app, "OCAP Playground", has released 20 internal versions since June 30. Interface interaction details have been optimized, and the Table view and Chart view of the result display area have been improved. The new Table view supports the presentation of nested data, and the format of the data fields is as user-friendly as possible. For example, the account balance can be shown in BTC. Block List and Transaction List have been added in the Chart view. The Transaction List uses the classic Sankey Diagram to visualize the flow of money in the blockchain network, so as to help developers make more valuable discoveries when previewing the query results. product01 Table views that support nested data product02 Chart views that support blockchain network fund flow visualization product03 In order to help developers successfully use OCAP Playground, Wang Shijun, an ArcBlock front-end architect, wrote an introduction guide:

OCAP adds the Ethereum API to support data queries on the Ethereum chain

On July 30, OCAP added the Ethereum API to support data query on the Ethereum chain, such as all ERC20 Token transaction data (figs. 1 and 2), as well as filling in block height negative values to query block data in new and old order (fig. 3). At this point, the OCAP Playground can be used to query the most mature public chain data of bitcoin and Ethereum.

FIG. 1 product04

FIG. 2 product05

FIG. 3 product06

The Ethereum support is still ongoing, and eventually we can resolve all the transactions for all the smart contracts. In the next two chains, we also plan to support transaction processing and event listening, to enable large transfers on the chain, for example.

OCAP Global Tour officially launched

At the same time OCAP Playground was launched on June 30, ArcBlock’s OCAP Global Tour officially kicked off.

The three-month global speaking tour is being led by the founder and CEO of ArcBlock, Robert Mao. With online sharing and offline forum roadshow, we are dedicated to preaching the blockchain 3.0 concept worldwide. We are delivering on our initial intention of ArcBlock becoming a true developer's blockchain platform of "sharing, co-governance and sharing," and sharing the word about OCAP technology. We’re also cultivating ArcBlock's global developer community, expanding ArcBlock consensus, and laying a foundation for promoting the popularization of blockchain technology.

Here are some snapshots of the events on the tour so far:

June 29 | Silicon Valley Live: Lecture 50, China-U.S. Blockchain Evolution Evangelist

Robert was invited to give a video talk at Lecture 50, China-U.S. Blockchain Evolution Evangelist, a joint venture between Mi Tan and U ZAN.

Robert detailed the technology and business logic behind the deep cooperation between ArcBlock and Eloncity. operation07

ArcBlock hired Alex Donn, an American genius hacker, as an adviser

On July 25, Robert met with American hackathon genius Alex Donn, who agreed to be an adviser. Donn will provide valuable experience and resources for the design and development of ArcBlock hackathons. ArcBlock plans to hold its first small-scale hackathons in Seattle in early August. It will lay the foundation for ArcBlock's subsequent hackathons around the world.

Media Coverage

With the debut of OCAP Playground, ArcBlock reached the climax of its second round of media communication, after the ICO. In July alone, eight in-depth interviews were released.

July 11 | High Finance: ArcBlock and Penta talked briefly about different ways of thinking about the direction of the common chain

Robert pointed out that "the blockchain status is like a database and there's no middle layer right now. We are groundbreaking, and this part is not so much about the blockchain itself. "

Here’s a link to the transcript of this discussion:

July 13 | Odaily Interview: Did Ethereum lead the public chain down the wrong path?

Robert believes that public chains should carry more value: "the public chain should focus more on tokens, and we want to make programmable tokens in the future, [but] only for token service, not Turing complete. This is a return to basics, like a database server, where someone also provides a web interface, but the database should do a good job of searching queries. Blockchain should do what it does best, not do general calculations.”

July 13 | Token Explorer Interview: OCAP Playground is released on schedule, making the development of blockchain more friendly

This is the second time that Robert was interviewed by Token Explorer. When Token Explorer asked whether he was satisfied with the development status of ArcBlock, he said, “I think we're still doing well, and there are some things that are exceeding our expectations, he said. The main challenge for us is to hire people. But in terms of the overall development of the product, I think we’re doing a very good job. We're not hiring as fast as we planned, but we're not behind in our product development, which means we have a high quality talent pool."

July 16 | Chain World Interview: Ethereum, EOS and other public chains are not friendly to developers

Robert pointed out that whether a public chain application is based on Bitcoin, Ethereum, or even EOS, its users and data are locked on its platform. If the application wants to migrate between platforms, the accumulated users, data, etc. will be lost. For example, although EOS has migrated from Ethereum, it protects the interests of EOS users in the form of mapping. The whole process is relatively complicated. By contrast, for example, the Internet is now mature, so whether an Internet app is based on Android or iOS, or Windows system, the application data will not be lost. Based on this idea, ArcBlock proposes to build the middle layer on the underlying technology and develop it, aka one-stop development services.


July 17 | Lei Feng Net Interview: Merging cloud computing is the future of blockchain.

Robert revealed that there will be a series of actions following the release of OCAP. First was the release of OCAP Playground, after which OCAP Playbook will be released. OCAP Playbook is an interactive document where users can exchange experiences in developing blockchain. Next comes the OCAP SDK, which uses OCAP for web and mobile applications. Playground will also launch the desktop version, which provides a complete set of tools for developers.


July 17 | KuaiMA Financial Interview: I'm "crazy" for blockchain technology!

Robert Mao saw blockchain’s transition out of the “geek circles” and into the mainstream. While many are just trying to make money, ArcBlock is focused on building ever-better technology.


July 20 | CoinVoice Interview: Most people only focus on the size of the current track, ignoring future possibilities

Robert thinks it's a good thing for a startup to choose a narrow path, because a narrow track is likely to widen. For entrepreneurs, it's especially good for them to choose a narrow focus. On the one hand, it means you don't have much competition and you can concentrate on the project. On the other hand, what looks like a narrow market today could actually become very large in the future. This is a business secret. Successful entrepreneurs always need to know the secrets that others do not know. These secrets seem obvious to them, but many people do not know them.


July 27 | Ear Finance Interview: From OCAP to Blocklet, ArcBlock opens the door to blockchain for traditional developers

"ArcBlock will ultimately be successful," Robert says, “upon the real establishment of a decentralized developer community. If you are a centralized cloud computing service, no matter how strong the technology is, you are unlikely to beat Alibaba or Tencent in the market. But if you create a consensus in the community, you have a much stronger competitive force, and with good technology, you will be able to achieve longer-term development.”


Technical Q&A

Q: What plans are in place to ensure that there are a large number of Decentralized Applications (DApps) and other projects using the ArcBlock platform after the ABT main line?

A: The first public beta of OCAP Playground has been released. There is still a long way to go before the platform is officially opened. At this stage of development, our main marketing strategy is to attract more and more developers to participate through hackathons. The hope is that every hackathon will produce tens of apps, at least a few of which are pretty good.

The public beta version of OCAP Playground is still in the testing stage, which allows developers to see what OCAP is and what they can explore and do. There is still a lot of work to be done by the formal product phase. Our ultimate goal is to launch the first developer conference in the first quarter of 2019.

Q: What are the advantages of using blocklet to build ArcBlock’s platform? A: The advantage of blocklet is that it's a framework for developing blockchain apps, which is our main focus, so it's OCAP-ready. Plus, with its serverless architecture, developers won’t have to worry about how to host blockchain nodes, how to host apps, or how to scale. We will ship OCAP first, then the blocklet.

Q: If ArcBlock is based on Ethereum, then TPS also depends on the speed of Ethereum? A: Yes and no. Yes, if you try to send transactions to it. No, if your application is mostly based on query, data visualization, etc. As you can see, the OCAP query is lighting fast in OCAP Playground, even though Bitcoin only supports 7 TPS.


On July 4, Robert, founder and CEO of ArcBlock, shared some reflections on his way to Japan:

Buddha said that our views on others reflect exactly what kind of people we are. Some people feel that their communities are all losers. We always feel that our community are the future developers and users. Because our ArcBlock vision is to make blockchain development easier, everyone can be a blockchain user, and each developer can develop blockchain applications.

No matter what the market is like, we will not change our plan of global preaching. Since before September 4th, 2017, we have been working hard to build the prototype in a bad market and write our own white again and again. Good market opportunities will be left to the prepared people. It's better to do something than to complain.


On July 31, Chen Tian, vice president of ArcBlock research and development, sent some pictures in WeChat's circle of friends to commemorate his leading technical team submitting 134 pull requests (code submission requests on the software hosting site GitHub) in July alone. This number exceeds any past month in the history of ArcBlock.Despite his busy schedule, Chen Tian posted two personal blogs in his spare time and shared his latest experiences with ArcBlock. insights02 insights03

July 2: Thinking, Problems, and Methods: "Even if ArcBlock’s R&D team has grown to dozens of people, it's still very small. In the context of what we want to do, if we don't find a more effective way to develop, we will be very tired, and the progress of development will be slow. For example, with OCAP, to create a set of API for developers, API must have documentation, SDK, API interface definition, and support for interface. There's a lot of duplication: API docs and API interfaces, and SDKs are constantly duplicating similar content and code. When we change the definition of API, we often change a place, and several places need to be modified. So we are looking for ways to "reduce dimensions.”

July 9: How to Improve Code Quality: "The programmer's product is code, and the user of the code is other programmers -- so high quality code is code that other programmers can easily understand. Note that this level of understandability refers to ease of understanding in structure, principles, and interfaces, not in the details of the code.”


ArcBlock community technology Q & A and weekly progress disclosure

On 7/11, 7/18 and 7/25, ArcBlock held its seventh, eighth and ninth community technical Q&As. In these interactions, Robert responds to a series of technical and operational questions about project progress, team building, product technology, function and application of ABT, asked by community users.
