3. FISCO -- Golden Chain Alliance creates a new era of public alliance chain

Public chain, alliance chain (permission chain) and private chain can be said to basically include three ways of using blockchain technology. In recent years, the planning, financing, development and ecological construction of the public chain can be said to have been carried out in a noisy manner. Some are real, and there are even more deceptions. It is noisy, noisy, muddy and sandy, and investors' money has really gone in. But not many are online, and the ecological construction of the few public chains that are online is also sparse. There are very few DApps, and the daily activity is even less. In short, not many current public chain projects can or are willing to survive. Ecological construction is even further away.

Private chains are self-built and internally run blockchain architectures of respective companies and institutions. Very little information is disclosed, but I believe that using your own money to do your own things and solve your own problems will not cause any problems. What a big deal.

The development of the alliance chain has always been low-key. Since blockchain technology was recognized by the mainstream economy and society, pragmatic mainstream economic institutions have been solidly carrying out research, development and application for about 4 years. During this period, the backbone of the alliance chain was formed, and another correct path was found for the implementation of blockchain applications and ecological construction. In a certain sense, the alliance chain has gone through the infant industry.In this period, it has begun to solidly enter the new era of "public alliance chain". The alliance chain's natural and strong relationship with mainstream economic industry resources also determines the alliance chain's mainstream status in the application prospects of blockchain technology.

With the dawn of the digital economy era and the popularization of distributed business models, blockchain technology has also been able to give full play to its advantages and become a representative of cutting-edge technology. In 2016, three companies, WeBank, a member of the Golden Link Alliance, Shanghai Wanxiang Blockchain, and Matrix Yuan, a member of Chinaledger, reached a strategic cooperation and jointly committed to exploring blockchain technology, and

The full name of Golden Link Alliance is Financial Blockchain Cooperation Alliance (Shenzhen). It was jointly established on May 31, 2016 by more than 20 financial institutions and technology companies including Shenzhen Financial Technology Association, Shenzhen Qianhai WeBank, and Shenzhen Securities Exchange. Non-profit organization established. As an open organization, Financial Institutions that voluntarily abide by the charter and companies that provide technological services to financial institutions can apply to join. So far, members of the Golden Link Alliance include more than 80 institutions in six major industries including banks, funds, securities, insurance, local equity exchanges, and technology companies.

On November 26, 2016, Golden Link Alliance released the "Financial Distributed Ledger Proposal", proposing five major principles such as legal compliance, traceability, security, privacy protection, and business orientation, as well as a value alliance , autonomous and controllable, safe and trustworthy, efficient and available, business feasible, flexible configuration, intelligent supervision and other seven propositions.

Purpose: Integrate and coordinate financial blockchain technology research resources, form a synergy and coordination mechanism for financial blockchain technology research and application research, and improve the research and development capabilities of member units in the field of blockchain technology. Explore, develop, and implement financial alliance blockchain suitable for financial institutions, as well as application scenarios based on this.

The General Assembly of the Golden Chain Alliance is the highest authority; the permanent body of the General Assembly is the Presidium, which leads the alliance to carry out daily work during the intersessions of the General Assembly and is responsible to the General Assembly; the Presidium has a technical committee (chaired by Application project work), Standards Technical Working Committee (presides over the establishment, formulation, review and release of standards), Advisory Committee (organizes external experts to participate in technical and standards discussions).

Jinlianmeng has established research directions in the fields of credit, equity, points, insurance, bills, cloud services, digital assets, financial product issuance and trading, and some of the projects have now been implemented or products have been launched. prototype.

The FISCO BCOS underlying blockchain platform is jointly built by the FISCO open source working group. Members of the working group include Beyond Technology, Huawei, Shenzhen Stock Exchange, Digital China, Sifang Innovative, Tencent, WeChatMembers of the Golden Link Alliance such as Bank of China and Yuexiu Jinke aim to create a secure and controllable underlying blockchain platform suitable for the financial field.

Financial services are one of the earliest application areas of blockchain. Blockchain technology brings advantages such as security and reliability, simplified processes, cost savings, reduced operational risks, and increased trust, and has the potential to reconstruct and sublimate the original financial industry infrastructure. The financial industry focuses on multi-party reciprocal cooperation and has strong supervision and high-level security requirements, which require node access and authority management. Therefore, the technical direction of the alliance chain has become the main choice for the financial industry.

At present, my country's financial industry is opening up to the outside world with unprecedented intensity, and the pace of financial innovation is also accelerating. Therefore, how to effectively balance the relationship between open innovation and risk prevention and firmly maintain the bottom line of no systemic risks is an important issue for the industry. challenges that urgently need to be addressed.

From the perspective of financial IT infrastructure, there are still some shortcomings and pain points in operational risks, moral risks, credit risks, information protection risks, etc.

First, financial IT system data may still be tampered with, forged, or have consistency differences.

Second, the infrastructure structures and business processes of different financial institutions are different, and even still involve many manual processes, which greatly increases operating costs and is also prone to operational risks and ethics. risk.

Third, financial business and financial cooperation may involve multiple participants or intermediaries, which can easily increase trust costs and friction costs. There are also certain issues of mutual trust, collaboration or cooperation reciprocity.

Fourth, financial business is often highly complex, and it is easy to miss records of all business elements. Sometimes it is difficult to trace the entire business process, and it cannot meet the needs of supervision and auditing.

Fifth, the data between different financial institutions are relatively independent, making it difficult to achieve safe and efficient interaction, resulting in high costs for repeated KYC, anti-money laundering, and anti-fraud, and also indirectly causing the loss of user data. Risk of disclosure by certain intermediaries.

Sixth, the availability and adaptability of centralized IT infrastructure are weak, and distributed technologies need to be used to improve robustness or adaptability.

As a combined infrastructure solution, blockchain technology can in principle respond to the needs of the financial industry. However, because the requirements of the financial industry are more diverse and strict, as a financial version of the blockchain solution, it needs to be based on the blockchain technology of the universal industry and according to the special business needs of financial institutions, existing technical levels, and laws and regulations. Requirements or conditions in other aspects shall be comprehensively considered from multiple dimensions such as business suitability, performance, security, policy, technical feasibility, operation and maintenance and governance, and cost.

First, the appropriateness of the business scenario. andNot all financial business scenarios require the use of blockchain technology. Generally speaking, when it comes to scenarios involving multi-party participation and peer-to-peer cooperation, the traditional centralized system architecture is often difficult to meet the needs, so you can consider using blockchain technology. This will increase multi-party mutual trust, improve business operation efficiency, and reduce business operation costs and friction costs.

Second, the performance of the blockchain system. Financial business often has characteristics such as massive transactions, high-frequency transactions, and timely confirmation. Therefore, the blockchain open source platform in the financial industry needs to analyze the business volume, potential business growth scale, and potential business growth scale that the blockchain system needs to support based on the current business scale of financial institutions. Technical performance index requirements such as concurrent business volume and response time. Since blockchain platforms using different technical modules, such as different consensus mechanisms, have greatly different performance support, it needs to be evaluated based on business performance requirements and combined with blockchain performance efficiency indicators.

Third, the security of the blockchain system. Blockchain can ensure the credibility of recorded data from a technical level and prevent data from being tampered with, forged and other risks. In addition, in terms of data sensitivity and security, it is necessary to evaluate the content encryption strength of the on-chain data, as well as access control, etc. Financial institutions need to choose mature, appropriate, and secure encryption algorithms based on the specific security requirements of their business.

Fourth, policy compliance. Blockchain is a set of technical solutions that, with reasonable design, can provide good support for existing businesses or complement existing centralized systems. However, when financial institutions use blockchain to conduct business, they must implement it within the country’s existing regulatory requirements and legal framework.

Fifth, technical feasibility. Blockchain technology has already been implemented in some financial scenarios, but it is still an emerging technology. It is necessary to fully evaluate the fit of the technology with specific businesses and its advantages and disadvantages compared with traditional systems before finally choosing the appropriate area. Demonstration and trial operation of the blockchain platform.

Sixth, operation and maintenance and governance capabilities. Since there are differences in operations and management between blockchain-based businesses and traditional centralized systems, and the continuous governance requirements of financial businesses are extremely high, corresponding planning and adjustments are required to evaluate the feasibility and sustainability of the new governance structure. , evaluate the impact of version iterations and the official launch of the system, monitor the operation of the blockchain system in real time, and ensure business controllability and financial environment stability.

Seventh, costs are controllable and economically feasible. Blockchain applications use technical features to solve specific problems in actual business. Applications that effectively solve pain point problems can bring great benefits to financial businesses, and the value of the application itself can also be revealed; on the contrary, if it cannot solve important problems in the industry , you need to face a trade-off between costs and benefits.

If a safe and reliable financial blockchain underlying platform can be built to meet the special needs of the financial industry, blockchain technology will be of great use in the financial industry.The place of martial arts.

For example, from the perspective of banking institutions, the key exploration directions are generally to apply blockchain technology to reduce clearing and settlement costs, improve middle and back-office operational efficiency, improve process automation, and reduce operating costs. In addition, in cross-border financial scenarios, blockchain can help realize ledger sharing among cross-border financial institutions, reduce reconciliation and settlement costs and dispute friction costs between cooperative banks, thereby improving the processing speed of cross-border business. and efficiency.

From the perspective of non-bank financial institutions, blockchain can be used to improve the authority of rights registration and information storage, reduce counterparty risks, solve data tracking and information anti-counterfeiting issues, and reduce audits. operating costs, etc.

From the perspective of financial regulators, blockchain provides regulators with consistent and easy-to-audit data. Through data analysis of inter-institutional blockchains, the audit process can be faster and more efficient than traditional audit processes. Precisely regulate financial operations. For example, in an anti-money laundering scenario, the balance and transaction records of each account are traceable, and no aspect of any transaction will be out of sight of supervision, which will greatly strengthen anti-money laundering efforts.

Designed an efficient, reliable, message communication protocol based on the blockchain network, referred to as AMOP (Advanced Messenger On-chain Protocol), focusing on the following functions:

 Based on the blockchain network, it supports cross-bank and point-to-point real-time message communication;

 Provides standardized interfaces for the interaction between off-chain systems and blockchain;
< br />  The blockchain system can actively call the business interface of the off-chain system;

The technical characteristics of this protocol are:

 In the point-to-point blockchain network topology , plan node communication paths to ensure message reachability;

 Can quickly sense node abnormalities in the blockchain network and automatically switch paths to resend messages;

 In communication Encryption technology is used in the process to ensure privacy at the communication layer.

Designed the contract naming service CNS (Contract Name Service). The design goal of CNS is to name the correspondence between the business layer and smart contracts, so that the business layer no longer cares about the relevant contract addresses. Similar to DNS on the Internet, the use of domain names makes it easier for users to remember how to access a website, and also gives the website great flexibility in terms of clustering, migration and expansion.

Ma Zhitao, chairman of the Golden Alliance Technical Committee, elaborated on the concept of the “public alliance chain”. He believes that the alliance chain should achieve self-sublimation and should be able to evolve into an ecosystem that provides services to the public, that is, a "public alliance chain."

Different from the public chain project’s idea of ​​“coming up with a plan first, raising funds, vigorously promoting it, raising the price, and finally investing in development”, the alliance chain project adheres to the idea of ​​“investing in development first with its own funds” , verify in the production environment, accumulate real customers and users, run steady trials and errors, and finally proceedThe "pragmatic" idea of ​​​​"promoting publicity". However, due to the focus on practical implementation and focusing on real applications, there is a lack of publicity, and it has no choice but to fall into the passive situation of "many people have implemented it, but few people applaud it". Golden Link Alliance hopes that through this This competition allows the alliance chain project team to come to the stage to display results, enhance the influence of the alliance chain, and let the public know more about the real application implementation and sustainable development of the alliance chain project.

4. Where is the "2018 Global Media Blockchain Summit" held

On the 19th, 2018, the "Global Media Blockchain Summit" was held at the Financial Town Hall of the Hong Kong Exchange. This summit gathered global More than a hundred media and dozens of top experts in the industry participated. At the meeting, everyone witnessed the establishment of the Global Media Blockchain Alliance (BIMG) and the release of the "BIMG Hong Kong Initiative", and discussed the development prospects and industry trends of the blockchain. and other topics were discussed in depth.

Professor Yu Guoming, a member of the Journalism and Communication Discipline Evaluation Group of the Academic Degrees Committee of the State Council and Executive Dean of the School of Journalism and Communication of Beijing Normal University, attended the "2018 Global Media Zone "Blockchain Summit" delivered a keynote speech titled "The Value Responsibility of Mainstream Media in the Technology Wave"

Yu Guoming said: "For the entire social communication in China and other major countries and regions in the world, including In terms of the communication ecology during the construction, development and evolution of blockchain, the value of traditional mainstream media should also be indispensable, although its share has indeed declined in a worrying way. , but it should be said that this kind of responsibility and value is still very important. ”

Yu Guoming further pointed out that the traditional mainstream media’s professional persistence, social status granting function and local advantages are its huge advantages. At the same time, with the development of social development and Internet technology, Blockchain is not only a technology, but also a way of reorganizing society to a greater extent. Yu Guoming said: "In Marx's words a hundred years ago, it is a new Internet technology such as 'the free alliance of free men'" a form of technology. To a large extent, it is a new form of upgrading and upgrading of new social evolution after Internet technology activates individuals. Such a new form requires mainstream media to play an important role in it, because in the process of a new social evolution like blockchain, it embodies what is called emergent evolution in systems science, that is to say, in The micro-power and micro-value released by Internet technology are a qualitative change in the development process and direction. It is a qualitative turning point in social development, field development, industrial development and market development. ”

Witnessed by all the guests, the Global Media Blockchain Alliance (BIMG) was officially established at the meeting. Alliance Secretary-General Ding Laibin pointed out in his speech that blockchain truly uses mechanisms to allow people to see the future Some changes may occur, and these changes may subvert the current status quo and improve social efficiency by a huge leap. In this process, the media function cannot be absent and should play a supervisory role.It exerts a powerful supervision effect of media and public opinion to allow investors to distinguish right from wrong.

Ding Laibin said: "The media is the public knowledge and conscience of society and the supervisor of industry development. To do this role well, we must be close to the game and stand where the sound of cannons can be heard, so If there was still a distance between traditional media and blockchain in the past, then let us eliminate this distance at today's summit. The listing of any company is not the end, but the starting point. The same is true for many blockchain projects, starting from the beginning Development also requires a lot of disclosure and planning, so that the company can be presented to all the public and investors without reservation, and it must be open, transparent, and consistent from beginning to end. Only in this way can the industry grow healthier and grow more rapidly."

< p>In the "BIMG Hong Kong Initiative" released at the event, Ding Laibin called on the media to join hands and work together to create an industry public opinion environment that is fair, just, legal and honest, vibrant, harmonious and orderly; at the same time, he encouraged the media to work in the blockchain industry In the information dissemination in the chain field, we should be open and inclusive, promote advanced communication, encourage ecological innovation, and continuously provide high-grade, high-style, and high-quality information and services.

6. When will the national standard for blockchain technology be completed

my country has started Establish a national standard for blockchain to promote the construction of the blockchain standard system from a top-level design, which is expected to be completed by the end of 2019 at the earliest.

In this regard, Zhao Wu, founder of Beijing Huashun Xin'an Technology Co., Ltd., also said that although blockchain has disruptive technological potential, we must realize that blockchain The blockchain is still in its infancy and is far from reaching the stage where it can disrupt the world.

Yu Kequn emphasized that an independent and controllable blockchain network is not technically controlled by others, but can also promote the healthy development of the blockchain. Security is the future life of the blockchain, and only its own security can bring blockchain technology to fruition. This requires us to pay equal attention to the development of its security attributes while developing blockchain technology, and even develop it ahead of time.

In this regard, Li Ming also said that an important part of the standard is the standard of information security, which also shows the importance of security for blockchain technology. He also pointed out that the formulation of blockchain standards does not mean that it will rapidly promote the development of the industry, but rather gives certain guidance to the industry. Previously, China had suffered a lot in terms of international intellectual property rights and standards. In terms of blockchain, China has now formed more than 200 patents in international blockchain, and has even stood at the forefront of the world's technology. Therefore, we also need to firmly grasp our right to speak.

I hope more people can learn about Bitcoin and blockchain through this documentary and explore the future together.

8. Direct to Digital Expo丨Blockchain Standardization and Application Innovation Summit released three innovative results

Zhang Ping, chief engineer of the Cyberspace Administration of Hebei Provincial Committee, introduced that blockchain is One of the hot spots focused on at this expo is the "Hebei Province Blockchain Special Action Plan (2020-2022)" released by Hebei Province last year, which clarified Hebei Province's blockchain technology and industrial application development goals-by the end of 2022, Hebei Province There are 20 leading enterprises and leading enterprises in the province's blockchain-related fields, cultivating a number of blockchain application products, striving to create 1-3 nationally renowned blockchain brands, and forming 3 blockchain industries with regional influence. Gathered in the park, the competitiveness of the blockchain industry ranks among the top in the country. To this end, Hebei Province is committed to introducing well-known domestic and foreign enterprises, gathering the most advanced technology, the most cutting-edge innovative concepts, and the most high-end human resources to cultivate innovative forces for the development of Hebei's blockchain industry.

"Hebei Provincial Characteristic Agricultural Products Blockchain Traceability Platform" was jointly developed by the Institute of Applied Mathematics, Hebei Academy of Sciences and Huaye Hebei Co., Ltd. Wang Zhiqiang, deputy director of the Institute of Applied Mathematics of the Hebei Academy of Sciences, introduced that the platform fully integrates blockchain with big data, Internet of Things, artificial intelligence and other technologies to realize the full chain traceability of production, logistics and sales information of specialty agricultural products, making production Operators, the public and regulatory authorities can participate together to build brands, enhance product value, and promote high-quality development of the agricultural economy.

It is reported that the “Hebei Province Specialty Agricultural Products Blockchain Traceability Platform” has three most prominent features:

First, one vote, one code, and object code locking. Intelligent identification and matching of business entity information and sales documents effectively solves problems such as multiple data sources, poor quality, and inconsistency between upstream and downstream.

Then there is the whole-chain evidence storage and accurate traceability. With the traceability code as the carrier and responsibility and flow management as the core requirements, agricultural product circulation data, electronic vouchers and other information are uploaded to the chain to achieve functions such as data non-tamperability and transaction traceability, and improve data throughput through the standardization of data storage and exchange. Key performance indicators such as volume and system response speed.

The third one is multi-source fusion and targeted regulation. On the basis of the blockchain system, for the characteristic agricultural product industry chain, a fusion model of production, circulation and inspection big data has been established to achieve targeted supervision and intelligent decision-making based on big data analysis, and comprehensively enhance the brand of on-chain products. Credibility.

“After three months of trial, the platform has been connected to 212 agricultural product trading markets, 9,807 online merchants, and 3,484 on-chain varieties, demonstrating strong application demand and development potential. "Wang Zhiqiang introduced that the Hebei Academy of Sciences is also exploring another quality route, cooperating with the Julu County Government to promote the "One Flower Supports Hundreds of Industries" project, using "blockchain empowering agriculture" as the entry point to create an agricultural digital estate, and then Promote the integrated development of primary, secondary and tertiary industries in the county, and ultimately achieve "one flower blooms, all industries prosper".
