On the evening of October 25th, the Political Bureau of the CPC Central Committee conducted the 18th collective study on the status quo and trend of blockchain technology development on the afternoon of October 24. Xi Jinping, the general secretary of the CPC Central Committee, emphasized that the blockchain is an important breakthrough for independent innovation of core technologies and accelerates the development of blockchain technology and industrial innovation.
At the same time, the general secretary pointed out that the current application of blockchain technology has extended to digital finance, Internet of Things, intelligent manufacturing, supply chain management, digital asset trading and other fields.

The alliance chain has always been a hot spot in the practice of blockchain landing.
Mutual chain pulse is concerned that after the big waves in recent years, the first echelon of the alliance chain has already formed, and plays a major role in accelerating the development of ecological construction and the realization of landing applications. This vanguard team includes: IBM's main contribution to Fabric, Weizhong Bank led the Golden Chain Alliance open source working group jointly developed FISCO BCOS, and the ant blockchain-led ant alliance chain.
The reason why these three alliance chains are listed as the first echelon, not only because they have deep contributions from large technology companies such as IBM, MicroBank, and Ant King. More importantly, the three parties have many commonalities: a large number of landing applications that have been produced, an independent research and development alliance chain platform (many domestic alliance chains adopt their technologies), open and open source operation ideas, years of research and development history, and Many fans.
The three pioneer chains "Pioneer Army" have explored different development paths in the process of developing blockchain technology and application.
Fabric, FISCO BCOS lead the open source direction ant alliance chain
In 2015 and 2016, blockchain technology is the trend. Ethereum has just been the main online line, and the emergence of smart contracts has inspired large companies at home and abroad to tentatively enter the field.
It is also at this time that the big enterprises of the first echelon of the future alliance chain, Weizhong Bank, IBM, and Ant Financial Services have opened their respective blockchain layouts.
In 2015, Weizhong Bank began to conduct blockchain research. In May 2016, Weizhong Bank and more than 20 financial institutions and technology companies including Shenzhen Financial Technology Association jointly launched the Golden Chain Alliance. Later in 2017, the Golden Chain Alliance Open Source Working Group launched the open source blockchain technology platform FISCO BCOS. In 2018, FISCO BCOS updated 9 iterations and in 2019 2.0.
In December 2015, the Linux Foundation and IBM led the launch of Hyperledger, an open source project designed to promote cross-industry applications in the blockchain. Hyperledger Fabric is one of the more important blockchain projects in Hyperledger. In September 2016, the preview version of Fabric 0.6 was released, mainly based on the code contributed by IBM; in March 2017, the 1.0 alpha version was released.
On the other hand, the domestic ant jinfu is also a blockchain experimental group established in 2015, and the ant blockchain was established in the following 2016. At the end of 2018, Ant Financial Services independently registered "Ant Block Chain Technology Co., Ltd.". But the original ant blockchain was not open source, perhaps exploring the future development trend. The ant blockchain announced the opening of the service market on October 22, 2019, and plans to open the alliance chain in November and launch the platform in Daap in December.
As a result, the situation of the coexistence of the three swords of China's alliance chain open platform was formally formed, and the construction of open source has become an important direction for the development of the Three Swords.
"Open source and community are important forms of blockchain technology advancement." In July this year, Zhang Kaixiang, chief architect of Weizhong Bank Blockchain and presiding over the design of FISCO BCOS platform, said that "Weizhong Bank always insists on openness." Thinking to embrace distributed commerce and build a distributed business ecosystem based on blockchain."
At the same time, the interchain pulse observed that among the three alliance chain platforms, FISCO BCOS's open source construction is the most prominent.
It is understood that FISCO BCOS currently has tens of thousands of community members, over 500 companies and institutions to participate in joint construction and sharing. In addition to GitHub, there are also official technical exchange groups, and successively launched various online and offline operations.
It is reported that its online activities include technical exchanges, event organization, project support and consultation, and regularly organize blockchain topic sharing every week. Offline activities include the nationwide tour of Meetup, the Golden Chain China blockchain application contest, and the hackathon activity.
Compared with foreign open source communities, FISCO BCOS has obvious local advantages, in addition to being more convenient for domestic developers to communicate in language, it is also more in line with the habits and styles of Chinese people.
Fabric is based on the Hyperledger organization, and its community building is relatively mature, and has now created an international community. In addition to being active on GitHub, it has also promoted a large number of offline Meetup and technology promotion activities; coupled with IBM's strong promotion, it has a large number of active users.
In addition, the ant blockchain has also organized an offline blockchain salon, and in 2019 held the Ant Financial Blockchain Innovation Competition. Mutual chain pulse learned that in the upcoming open alliance chain products, the ant blockchain is proposed, and the members on the chain will all pass identity authentication, and use multiple parties to participate in the collective consensus model. However, before this, the ecological development of the ant blockchain was relatively limited to its own enterprise system.
It is worth mentioning that in terms of distributed authentication, Hyperdyger's Indy, and Weizhong Bank's WeIdendity project are also typical solutions in this field.
In addition to the above-mentioned online and offline activities, FISCO BCOS seems to be more complete in terms of content construction than the Fabric and Ant blockchain. The typical case discussed in the offline activities will be launched in the form of a video course to the People's Network Mu School Blockchain College for users to open learning; the platform also cooperates with many famous universities in China to open a blockchain course, which can be obtained after completion. Credits and certificates.
Not only that, it is understood that the current number of FISCO BCOS open source ecosystem partners has more than 500, including regulatory agencies, government departments, standards organizations, research institutions, universities, technology communities, system integrators, cloud platforms, consulting companies, security Various role partners such as assessment, media, and individual developers.
The application scenarios of the three major alliance chains are rich in the number of fabric and FISCO BCOS applications.
The development of the open source ecosystem is often achieved through the continuous advancement of application projects.
Mutual chain pulse pays attention to the fact that the first echelon's FISCO BCOS, Fabric and Ant Alliance Chain projects have certain similarities in application, that is, they all start from finance and expand into multiple fields.
FISCO BCOS is the underlying platform of enterprise-level blockchain that meets the needs of the financial industry, which is led by domestic enterprises, which is research and development, safe and controllable, and open source. Starting from finance, but not in the financial sector, FISCO BCOS gradually covers more cultural and copyright, judicial services, government services, Internet of Things, financial industry, smart communities, public welfare and other applications.
These areas are in line with the deep integration of the real economy mentioned by General Secretary Xi Jinping in his speech.
According to the disclosure of the FISCO BCOS open source community in the first half of the year, the number of landing applications based on FISCO BCOS development in the production environment has exceeded 60. In terms of copyright, in July of this year, People's Daily launched the “People's Copyright” platform, which builds a news copyright alliance chain based on the underlying technology of FISCO BCOS blockchain. In terms of government affairs, in February this year, the Macau government adopted blockchain technology as its The main fulcrum, promote the construction of smart cities in the Macao SAR and the development of future cities; in the case of judicial deposits, in January this year, Shenzhen Securities Co., Ltd., together with Pacific Insurance, Guotai Junan and other institutions, initiated deposit-seeking services based on FISCO BCOS to achieve synchronization across the entire network. The data is not tampered with, and the trace information cannot be denied…
Due to the open source nature of the platform, in addition to the disclosed application projects, there are actually many application projects that are constantly being explored, and the number of landing applications that actually run in the production environment may not stop there. As early as December 2018, the Golden Chain Alliance China Blockchain Application Competition received nearly 300 entries based on FISCO BCOS.
While the number and speed of landings are increasing, the quality of its application projects is also guaranteed.
In July, the China Electronics Technology Standardization Institute and the third China Blockchain Development Competition hosted by the Xiaoshan District People's Government of Hangzhou, Zhejiang Province, four of the 11 award-winning projects were based on the FISCO BCOS underlying platform.
In addition to these applications, in September, Weizhong Bank released the “Benefit” of the blockchain optimization social governance model reference framework, which proposed a new development path for the development of the blockchain industry. From this point of view, Weizhong Bank advocates the realization of the social value of the blockchain.
Fabric was originally defined as a general-purpose blockchain open source framework that does not separate the industry. And it is the first to promote the application of the financial sector, and then develop into many fields.
According to IBM, Fabric currently has more than 400 projects (including POC), including Maersk, Wal-Mart, Lenovo, and the Postal Savings Bank. In July of this year, the New York Times also planned to use the blockchain that Fabric cooperated with the technology giant accelerator project IBM Garage to crack down on fake news.
The target of the ant blockchain is similar to FISCO BCOS. It is to build a low-level financial and economic blockchain platform with independent property rights, and to bloom in many aspects such as people's livelihood, business, and government affairs. The ant blockchain is indeed moving along this goal.
At the Yunqi Conference and Ant Block Chain Ecology Summit held in late September, Jiang Guofei, vice president of Ant Financial Group, revealed that the ant blockchain has landed more than 40 applications. Including cross-border payment, supply chain finance, general traceability, electronic bills and other industry sectors. In the same period, it announced the cooperation with Bayer, the world's largest seed and pesticide company, and further expanded its application direction.
From this point of view, FISCO BCOS, Fabric, Ant Alliance chain three major alliance chain platforms are aimed at the enterprise-level, production-level alliance chain, taking the financial sector as a force to incite other areas of development. From the application development of the three platforms, the alliance chain has become the advance force of the blockchain. The domestic FISCO BCOS is closely following the Fabric, accelerating the implementation of the application landing, and there is a great trend of “the waves of the Yangtze River”.
The technical strength of the "first three pioneers" of the first echelon of the alliance chain is on the same page
The landing of various alliance chain application projects is supported by the technical strength of each platform. Mutual chain pulse has three advantages in terms of performance, security, expansion and ease of use, each with its own advantages.
(tabulation: interchain pulse)
FISCO BCOS currently supports both PBFT and RAFT consensus methods. PBFT is a BFT-like consensus that enables networks to support weak trust environments. FISCO BCOS also optimized the PBFT consensus process to fully improve consensus efficiency. In addition, FISCO BCOS combined with smart contracts can support nodes to dynamically add and exit the network. The ant blockchain also supports the PBFT consensus algorithm.
Fabric used the PBFT consensus protocol in version 0.6. In version 1.0, the Kafka approach was used to achieve consensus. Compared with the POW consensus algorithm, Kafka is more efficient, energy-saving and environmentally friendly, and provides a fault-tolerant mechanism to ensure stable operation of the system. However, Fabric has certain limitations. Many industry commentators believe that Fabric's kafka mechanism is not decentralized, and the current version of Fabric's single-chain throughput is 3000 TPS, which is not superior to FISCO BCOS and Ant Alliance.
At the same time, the TPS of the alliance chain platform led by the two major Chinese teams has exceeded 10,000, and the TPS of the ant blockchain has reached 25,000+; the block rate has reached the second level. Security, scalability, and ease of use also have their own characteristics. FISCO BCOS single-chain measured TPS over 10,000, second-level confirmation, with high consistency and transactionality, and supports parallel expansion of parallel multi-chain, its expansion and ease of use, this year has released FISCO BCOS 2.0 version also proposed The “one-two-wing multi-engine” architecture solution, which refers to the group architecture, allows for multiple different books in the network. Each account book is a separate group. Nodes can choose to join certain groups and participate in the consensus of the group. Storage, as the number of teams increases, the throughput of the system can scale horizontally. "Two wings" refer to parallel multi-chain processing models and distributed storage, respectively. "Multi-engine" is a fusion of many functional components. This provides more platform support for the rapid application of the alliance chain.
From the perspective of open and open source, we observe three platforms. Both FISCO BCOS and Fabric are open source, and the ant alliance chain is about to open.
However, it is worth noting that General Secretary Xi emphasized in his speech: "We must use the blockchain as an important breakthrough for independent innovation of core technologies, clarify the main direction, increase investment, focus on a number of key core technologies, and accelerate the promotion of the zone. Blockchain technology and industrial innovation development.” FISCO BCOS and ant blockchain are blockchain platforms with independent innovation capabilities and a number of key technologies in the Chinese alliance chain.
As the blockchain gains recognition and support from government forces, it will usher in rapid development. The micro-banks lead the FISCO BCOS jointly developed by the Golden Chain Alliance open source working group, the main contribution of IBM, and the ant alliance chain led by the ant blockchain. These three "vanguard" members will help the development of the blockchain. And further promote the integration of blockchain and the real economy.
