Weizhong Bank's Blockchain Implementation Practice and Technology Innovation
In the course sharing, Li He explained the achievements and experiences of Weizhong Bank on the blockchain landing in recent years.
As one of the first domestic companies to explore alliance chain technology, Weizhong Bank established a blockchain research and development team in 2015, and launched the first domestic production-level blockchain application in the financial sector in 2016. Platform ", and by 2017 the Joint Golden Chain Alliance Working Group will open source and independently develop the blockchain underlying platform FISCO BCOS. Li He used "as thin as ice" to describe Weizhong Bank's mood of exploring in the blockchain unmanned area.
If you want to arrive in the spring, you must leave in the winter.
After years of development, FISCO BCOS has been widely applied in many fields of the industry. The latest data shows that in terms of applications, hundreds of applications are based on FISCO BCOS research and development, and more than 60 applications operate in production environments, covering financial services, medical and health, cultural copyright, education, intelligent manufacturing, sharing economy, social management and other fields.

What are the commonalities behind so many cases? Li He proposed two key points of distributed shared ledger and trusted data exchange . The former need not be said much. For the latter, Li He believes that it will generate greater social value in future distributed commerce.
Taking Weizhong Bank and the Macau Special Administrative Region Government for the certification of the smart city of Macao as an example, based on WeIdentity's self-developed and completely open source entity identity and trusted data exchange solution WeIdentity, it can well protect the local citizens. Private data, truly "return data to the people".
More than WeIdentity, after nearly 5 years of exploration, in terms of technical innovation, Weizhong Bank and the Golden Link Alliance open source working group created the open source blockchain underlying platform FISCO BCOS, independently developed and open sourced the middleware platform WeBASE and the message collaboration solution WeEvent Wait. In terms of applications, hundreds of applications are based on FISCO BCOS research and development, and more than 60 applications operate in production environments, covering financial services, medical health, cultural copyright, education, intelligent manufacturing, sharing economy, social management and other fields. In terms of open source community construction, Weizhong Bank, in conjunction with Shenzhen Fintech Association and other units, initiated the establishment of the largest domestic alliance chain organization, Golden Chain Alliance, which gathered over 500 enterprises and institutions and tens of thousands of developers around FISCO BCOS to build the largest Domestic open source alliance chain ecosystem. In terms of talent training, Weizhong Bank has opened various forms of high-level talent training channels. In terms of standard formulation, Weizhong Bank has participated in the formulation of several international standards of ISO and IEEE, helping China to improve its international voice in blockchain.
Zhang Long introduced the blockchain technology architecture innovation of Weizhong Bank.
For developers, the underlying platforms, smart contracts, service interfaces, and distributed applications all have pain points to varying degrees.
For example, on the underlying platform, developers have questions about the concept of the consensus mechanism, the complexity of chaining, and whether the performance meets business requirements.
In terms of smart contracts, there are problems such as high learning costs, limited development languages, and incomplete development tools.
In terms of service interface, there will be many problems. If I encounter an exception and report an error, how do I troubleshoot? How to generate a private key, etc.?
At the business level, it will also face: Is there a reference to DEMO? Can it support big data processing? How to manage accounts and private keys? Is there a visualization tool? What about monitoring and auditing?
(Zhang Long, Senior Blockchain Architect, Weizhong Bank)
To this end, Weizhong Bank proposes a "3 + 2" alliance chain technology path (3 refers to compliance, security, and stability. 2 refers to easy-to-use / friendly, high-performance) and a package of open source solutions (including FISCO BCOS , WeBASE, WeEvent, WeIdentity).
As the underlying platform, FISCO BCOS has more than 30 code warehouses, 100,000 lines of code, and 100,000 word documents.
In March this year, FISCO BCOS launched version 2.0, forming an integrated two-wing multi-engine architecture .
One, refers to the group structure. Multiple groups can be opened on a chain, each group running a different business, each group has an independent ledger, taking into account privacy. According to Zhang Long, FISCO BCOS has made a lot of optimizations in user experience. The fastest way to build a chain can be completed in 5 minutes.
Two wings, including parallel computing models and distributed storage. The former makes the alliance chain application fly higher, the latter makes the alliance chain application fly further. Usually, the blockchain network does transaction packaging, which is processed serially. FISCO BCOS maximizes the performance of the CPU by building DAGs and performing parallel operations. Distributed storage can achieve parallel expansion by separating the data and transactions of the underlying chain, simplifying some complex storage models into the database, and optimizing local storage.
Multiple engines, including pre-compiled contracts, consoles, virtual machines, MPC suites, etc., are used to escort alliance chain applications.
After having a strong underlying platform, Weizhong Bank found that there are still bottlenecks in the use of blockchain by enterprises. This is because most companies do not pay attention to the underlying technology, but hope to use the platform out of the box.
For this reason, Weizhong Bank open-sourced the middleware platform WeBASE between the underlying platform and the upper-level applications to help enterprises shield the complexity of the underlying technology. The application side only needs to focus on the real business logic. WeBASE covers the entire life cycle of blockchain applications from management platforms, smart contracts, transactions, and data.
With the underlying platform and middleware, that's not enough. Companies want to quickly know in which scenarios they can use blockchain.
Based on this, Weizhong Bank abstracted many different forms of appeals, created a series of universal solutions, and made open source, such as the aforementioned entity identity and trusted data exchange solution WeIdentity, message collaboration solution WeEvent.
In addition, Zhang Long also shared and provided solutions to the challenges faced by the current blockchain with many nodes, large amounts of data, privacy protection, and account governance.
Industry digital integration and transformation, talent has become a prominent problem
In the roundtable discussion with the theme of "Industrial Digital Convergence and Reform", the topic of blockchain talents became a hot topic for guests.
Yin Xiaodong said that the blockchain may now enter a period of rapid development, and currently there is a shortage of development engineers. From the application scenario, the designers of the token economy and blockchain architects are also scarce.
Xu Ruochen classified talents. The first category is operations or media. In fact, this kind of talents do not need to understand technology, as long as they know the function of the blockchain, the main examination is the ability to communicate, copywriting or speculation.
The second category is technical posts. There are two development paths for this kind of talents. One is to go to the underlying technology and the other is to develop the upper-level DAPP. The former needs to choose a main technical direction, such as algorithms, cryptography, or zero-knowledge proof, and continue to study. The latter accounted for half of the technological capacity and the ability to understand industrial needs.

Zhang Long mentioned that blockchain talents need to maintain patience and continuous thinking and learning. In addition to technical knowledge, they need to have solid computer-related theoretical knowledge. They also need to understand cryptography, distributed architecture, P2P networks, and consensus mechanisms. The core technical knowledge of the blockchain, the most important thing is to cultivate the blockchain thinking. The first type of so-called blockchain thinking is "blockchain +", which is the saying goes that holding a hammer to find nails and using the characteristics of blockchain technology to solve problems encountered in real business scenarios. The other is "+ blockchain", a business party in the vertical field, based on the blockchain technology to upgrade the original business.
Colleges and universities are important for training blockchain talents. Xu Ruochen believes that industry without education has no foundation, and education without industry has no soul . Colleges and universities, as the main battlefield for talent training, should establish a talent training system that integrates production, teaching, and research. In this regard, Weizhong Bank cultivates blockchain talents by cooperating with some well-known colleges and universities to establish blockchain courses and jointly organize college and university blockchain innovation contests.
Technological innovation under the integration of blockchain technology, multi-domain + blockchain
In the roundtable forum of "Technological Innovation under the Fusion of Blockchain Technology", we found that the blockchain is integrating and developing with different industries.
In the gene technology industry, we know that everyone is composed of different genes, and these genes can be regarded as human source code. According to Yu Yuchao, founder of Shengwu Science and Technology, at present, there is a problem of stealing user information in the gene detection market. For example, when a user does a paternity test for a gene, it is usually enough to do 21 gene loci, but if a user spends two or three hundred dollars online to buy a gene test product, it may actually affect 900,000 users Genetic loci for testing. The credibility, transparency, and confirmation of power brought by the blockchain can just solve the above problems. According to Yu Yuchao's vision, in the future, with the blessing of blockchain technology, everyone can independently contribute their genetic information to certain projects and share the dividends after the development and marketing of new drugs.
In the judicial industry, Hangzhou-based Yibi Technology entered the field of judicial arbitration in 2017. In February 2018, it cooperated with Weizhong Bank and arbitration institutions to issue the first domestic blockchain arbitration letter.

In the banking industry, FISCO BCOS, an open-source blockchain underlying platform created by Weizhong Bank in conjunction with the Golden Chain Alliance, has recently become the sole supporter of BSN's domestic domestic alliance chain underlying platform. BSN is a global infrastructure network based on blockchain technology and consensus trust mechanism initiated by the National Information Center, China Mobile, China UnionPay, and Red Date Technology. In Deng Weiping's view, FISCO BCOS can become the first underlying platform for the national team. First, the selection of the alliance chain is consistent with BSN, and second, the two parties are highly consistent in the concept of open source and open source. The core idea is that FISCO BCOS has more than 60 applications that run stably in the production environment, which has proven that the platform is robust and usable in a wide range of practices.
