⑴ What are the blockchain projects in China?

There are still many excellent blockchain projects in China

⑵ At present, China is relatively reliable What are the spectrum of blockchain public chains?

In the past, whenever we mentioned blockchain, we would always think of foreign products, such as Ethereum, but when we talk about this topic today, I think more China’s own blockchain technology comes to mind.

At present, the mature applications of blockchain technology are more concentrated in some public chain projects, because many application projects need to be developed based on this, so I think that the current global One of the general directions for implementation is public chain projects. It is still too early to talk about maturity. After all, Bitcoin and Ethereum are still very congested. There are still many old problems that have not been solved, and many new problems will arise. The more well-known ones are Bytom, Ulord (the project is abroad, but the technology is provided by the domestic company Hunan Tianhe Guoyun Co., Ltd.), Quantum Chain, Xiaoyi NEO, Gongxinbao, etc.

Ulord is a point-to-point value transfer public chain. By building the underlying blockchain architecture and digital resource distribution protocol, it supports third-party developers to build their own applications on top of its open source protocol, and interacts with many industries. Partners work together to build a complete ecosystem of blockchain technology and applications.

Based on various rules and protocols created by Ulord, it is convenient to graft various digital resource application scenarios including text, pictures, music, videos, software, etc., and provide direct communication between information creators and consumers. docking platform. Third-party developers can build their own economic systems in Ulord, or they can focus on building various applications around Ulord, using the UlordToken in Ulord as in-system credentials.

For example, an experience sharing platform can be built on Ulord. Experience sharers price the published experiences. People who obtain experience information trade on the platform, and every fee paid to the experience sharers will be paid immediately. Account; product promoters can publish advertisements on Ulord, price the advertisements, and people who are interested in the advertisements and click on the advertisements can get certain benefits, etc. Different from the previous model where information transmission requires the help of platforms or other centralized institutions for dissemination and profit, the intermediate links are removed, and information providers and consumers are directly connected through Ulord, ensuring the maximization of the interests of the original creator.

⑶ Which blockchain projects are worth investing in now?

Nowadays, blockchain has been vilified by many players. When it comes to blockchain, the first reaction of many people is that they are scammers. In fact, blockchain has now begun to study practical applications in many industries, such as logistics, medical care, etc. If you invest, you can start with application implementation, but the cost is too high and the technical requirements are relatively high. The other is mining. Although the income will be slower, it is still relatively stable. Don't believe in all kinds of stocks with high profits and high returns. The greater the temptation, the deeper the pit.

⑷ The core technology of Complex Beauty - the development of Chain33 blockchain system

After understanding the basic situation of the company, Gao Guofei and his party sat in the conference room with Wu Sijin and listened to the introduction of the Chain33 blockchain system, the core technology of Complex Beauty. Regarding the development of blockchain technology, District Chief Gao Guofei was very optimistic. He said: "Blockchain must be a cutting-edge technology. In the future, the underlying layer must be highly transparent and highly credible." He also praised the beauty of complexity, "You guys It is an enterprise with real talents and real abilities." Wu Sijin also said that the core competitiveness of Complex Beauty is talent. Hangzhou has the best technical developers in the country and even the world. Complex Beauty has now attracted a large number of technical talents to join, many from Alibaba, Huawei, etc.

At the end of the survey, District Mayor Gao Guofei continued to have in-depth exchanges with Wu Sijin, hoping to hear what support the company needs from the government at the current stage of development. When talking about the financial situation of enterprises, District Mayor Gao Guofei also pointed out that the district's financial development guidance fund can focus on the next step, so that enterprises can put down their burdens and focus more on research and development. District Chief Gao said humorously, “I can’t understand blockchain technology now, and I won’t be able to reach it in the future (when it develops).” Wu Sijin also said that 33 Complex Beauty is now developing steadily, and leaders come to guide us more and give us confidence. What should we do? All difficulties can be overcome.

Finally, in a pleasant and peaceful atmosphere, Gao Guofei and his team’s visit and research on Complex Beauty came to an end.

⑸ Cheers to GOC, the explorer of the public chain governance model!

Text/FengLan Fanzhou

Written in front

I remember that a certain boss once pointed out how to structurally grow, iterate, evolve, and repair the development of public blockchains. Tokens, applications and governance are the three core elements of a public chain, and a complete governance structure design is indispensable for achieving development goals. Only when the above requirements are met, can the public chain blockchain be truly realized? .

The exploration of public chain governance has always been a top priority in the development of blockchain projects, because it, together with the incentive mechanism, is the basic mechanism to promote the development of blockchain projects. However, under the trend of thinking that the interests of human nature come first, most blockchain projects still have insufficient awareness and insufficient attention in terms of governance, making advancement difficult.

I believe everyone has a deep understanding of the many problems that exist in the governance of UGC content platforms, because most platforms now adopt the incentive distribution logic of tokens: high lock-in, high weight, high return, here Stimulated by similar mechanisms, in order to earn more Tokens, some users post irregular comments and likes in an endless stream. They enjoy the considerable dividends brought by the lack of platform governance.

“Bad writing drives out good writing”. Because of this, some UGC platforms suffer from serious consequences caused by neglect of governance design in the early stage, resulting in governance deficiencies (defects). Some platforms have also launched various governance measures to remedy the situation, but these measures obviously cannot avoid the shortcomings of a high degree of human governance. Most of the time, "man-governed" is constrained by time and space, efficiency, ability and emotion, and the governance effect is not ideal.

Regarding the future of blockchain development, how to open the road to good governance is also urgent. I remember what teacher Yunpeng said: Good governance is the ideal state and ultimate goal of governance. Good people govern themselves. Good governance, good governance, and self-governance with good intentions.

The GOC blockchain consensus governance public chain initiated by the GOC Lab community, as a pioneer explorer of public chain governance, is opening the door to good governance for the joint construction of the blockchain ecosystem.

What is GOC?

GoCLab is a community focused on the exploration and innovative practice of blockchain governance models. The GOC (Governance of Consensus) blockchain consensus governance public chain initiated by the GOC Lab community is based on EOSIO As a base, it is an experimental and research public chain used to explore on-chain governance, models and tools, aiming to create a public chain with the best global governance practices.

GOC Lab has joined forces with GRAVITYPOOL, Fudan Blockchain Laboratory, PalletOne, EOSPEAL, MIXMARVEL, BlockGo, INTERCHAIN ​​Lab and many other outstanding projects and institutions in the blockchain field to explore and practice together for the future The governance model of “blockchain economy”, minimizing the cost of trial and error, evolving the optimal governance model, maximizing the participation and innovation of ecological members, and striving to build the most valuable "blockchain economic community" in the blockchain world.

Innovation of GOC public chain governance mechanism: GN system governance nodes

According to the white paper: At present, a large number of participants in public chain projects are short-term investors, pursuing short-term capital gains. The decisions made did not consider the long-term development of the ecosystem at all; in addition, due to the lack of a reward mechanism and the small number of tokens held by participants who made important contributions to the initial construction of the system, they gradually lost their right to speak and left the ecosystem in large numbers, resulting in short-term investment The ecological problem of people flooding in has become more and more serious. The governance system designed by GOC can solve this problem well and retain these ecologically important "aboriginal people".

How to become a system governance node (GN)?

——Voluntariness principle: System governance nodes (GN) join voluntarily, and TOKEN holders only need to lock a certain amount of GOC tokens to become a system governance node. There is no limit on the quota. Any TOKEN holder who is interested in system governance and willing to participate in public chain governance can participate and participate in governance.

——Reflecting equality: Investors who own a small amount of tokens but are willing to participate in public chain governance and make effective suggestions for public chain governance have the opportunity to participate in ecological governance construction and ensure token The holder’s right to speak.

——Avoiding concentration of power: The system governance nodes vote through the "one household, one vote" method instead of voting according to the number of tokens, which effectively avoids the loss of a small number of people due to large amounts of currency holdings. The resulting excessive concentration of power creates tendencies in ecological governance decisions and reduces the risk of participants holding large amounts of tokens controlling the system.

What can the system governance node (GN) do?

“System governance nodes” can vote and make decisions on proposals. Only voting “system governance nodes” can share the governance rewards, thus encouraging more people to actually participate in governance work. It’s not just about occupying a spot. The main work content of the system governance node includes:

- Review fund application proposals, vote for outstanding dApp projects, and use a part of the inflation tokens as funds to support the development of these projects;

——Review the materials provided by both parties to the arbitration and vote whether to support the request.

What are the sources of system governance node (GN) revenue?

The income of system governance nodes comes from tokens generated from inflation income. Part of it is used as financial support for outstanding projects in the system, that is, project fund application proposals, to promote the development of the system. Another part of the inflation income will be awarded to the system governance node GN as its voting reward. Note that only GN that has fulfilled its voting obligations are eligible for rewards..

GOC Public Chain Development Outlook

Since the launch of the GOC mainnet, it has successively entered platforms such as Lichang, and its development has been relatively slow. Perhaps the current thinking and positioning of GOC decentralized operations is a little too ahead of reality, and more patience is needed for understanding.

GOC is a decentralized organization. The GOC lab community is jointly initiated by multiple institutions (individuals). There is no concept of founder or project leader, and it advocates a decentralized management and development model. , the decentralized model adopts a decentralized model that empowers all users and amplifies users’ participation rights.

In short, GOC’s governance model has pioneered public chain governance. I believe that more discerning investors (communities) will definitely join the wave of GOC public chain construction and fully understand Understand the value and meaning behind it, and truly promote the sustainable development of public chains with ideas, vision, and real work.

⑻ [One of the top ten blockchain government cases] Ant Blockchain-Hangzhou Internet Court Judicial Chain Case

According to Hangzhou Daily, September 18, 2018, Hangzhou The Internet Court announced that the judicial blockchain was officially launched online, becoming the first court in the country to apply blockchain technology to resolve disputes. The judicial blockchain makes the entire process of electronic data generation, storage, dissemination, and use trustworthy.
The complainant can submit an online complaint through the online complaint portal.Electronic evidence such as contract delivery, rights protection process, and service process details are jointly witnessed and endorsed by nodes on the chain such as notary offices, judicial appraisal centers, CA/RA institutions, courts, and Ant Financial, providing one-stop services for prosecutors. . The judicial chain has greatly reduced the cost of offline evidence storage and collection, and improved the efficiency of the judgment process, thus enabling many cases that were previously unworthy of prosecution due to the high cost of rights protection to be able to achieve better rights protection through the blockchain; Judicial The chain solves the problem of low judicial service efficiency, realizes the integration and sharing of judicial data, and breaks down data silos; the judicial chain promotes the construction of a social credit system, reduces judicial costs, uses technology as an engine, promotes innovative development, and leads the transformation, upgrading and reduction of judicial services.

Citing the analysis of the "Blockchain Judicial Evidence Application White Paper" from the Trusted Blockchain Promotion Plan, with the rapid advancement of informatization, a large amount of evidence in litigation is presented in the form of electronic data. The specific manifestations of electronic evidence in judicial practice are becoming increasingly diverse, and the frequency of use and data volume of electronic data storage have increased significantly. Different types of electronic evidence are formed in different ways, but they generally have the characteristics of being easy to perish, easily tampered with, and highly dependent on technology. Compared with traditional physical evidence, it is more difficult to determine the authenticity, legality, and relevance of electronic evidence in judicial review. .

In judicial practice, parties generally lack the ability to produce evidence, and the electronic evidence provided to the court is of poor quality. There are a large number of problems such as improper evidence collection procedures, incomplete evidence, and poor pointing to the facts of the case, which directly affects the electronic evidence. The proportion of evidence admitted in litigation.

The traditional storage method of electronic evidence is essentially a centralized storage method, which may easily cause the storage data to be lost or be compromised. .

At the same time, electronic data relies on electronic media for storage. For storage security, multiple backups and other methods are often needed. In addition, electronic media have a long service life, which makes storage costs higher.

(2) Problems in evidence collection

Currently, when some locally generated electronic data is collected for evidence, the originals are intelligently retained in the device that generated the electronic data, and the original evidence and Devices are indivisible. Once the original evidence leaves the device, it becomes a copy and cannot become the basis for a final verdict. This results in many limitations in litigation cases.

In addition, the Internet software service provider cannot give a definite answer as to whether the so-called original is the true, original and complete data at the time when the time occurred. It is also doubtful whether the evidence obtained is the original.

(3) Problems in demonstration

Electronic data display and fixation are important aspects of data use. Since electronic data exists in the form of electronic information stored in electronic hardware, To obtain its contents requires the use of response software to read andThis brings difficulties to the demonstration, and may also increase the burden of proof on the parties due to the need for notarization, and waste social judicial resources.

(4) Issues in Evidence

In litigation, both parties will submit their own electronic data as evidence. When the parties individually control their own data, it is easy for the evidence submitted by both parties to be inconsistent or even contradictory. In the absence of other supporting evidence, it is very difficult to determine the authenticity of the evidence, and the electronic data submitted by both parties cannot be used as the basis for deciding the case. In this situation where the facts of the case cannot be determined, the judge is likely to have to rely on assigning the burden of proof to decide the case. The general principle of allocating the burden of proof is that whoever makes the claim must provide evidence. If he cannot provide evidence, he will bear the consequences of losing the case. In this case, a party that actively tamperes with its own data can benefit from this burden of proof arrangement.

(5) Problems in evidence identification

All evidence "must be verified to be true before it can be used as the basis for finalizing a case", which is the most important and universal evidence in the world. One of the principles of justice. The identification of evidence is usually a process of identifying the "three properties" of evidence, namely the authenticity, legality and relevance of the evidence. Electronic data used as evidence also needs to pass the "three characteristics" judgment. Due to the large amount of data, strong real-time nature of electronic data, high storage costs, and difficulty in identifying the originals, it is still difficult to identify the "three properties" of evidence. Electronic data often cannot support the case because it is difficult to identify, which is detrimental to the case. Both the judge and the parties caused greater pressure.

Quoting from the sharing by Li Zhiguo, head of Ant Financial’s judicial evidence deposit products, titled “Ant Blockchain’s Exploration in the Field of Judicial Evidence”, he believes that in the past 20 years, the Internet industry has The key word is connection. In the PC Internet era, terminals were connected through PC interconnection. At that time, companies that discovered this trend seized huge business opportunities such as portals and search engines. In 2013, we entered the era of mobile Internet. In this era, many smart terminals and personal devices are connected together through the mobile Internet. The number of terminal devices and online time have been greatly improved. Those who seized the opportunity at this stage created super applications such as Weibo, WeChat, and Alipay. A very important change that we are currently paying attention to is that as the changes in connections continue to expand, the quality of connections has also changed greatly. This is called the second curve. The original object of connection was information, but now it is likely to become assets.

So what is the difference between assets and information? There are three main differences.

First, assets are unique, while information can be copied infinitely. In the Internet era, the cost of information transmission can be minimized through copying. However, when the connected object is an asset, a fatal flaw arises, that is, it cannot be transmitted through copying. After the asset is given to a person, can no longer give it to himOthers.

The second point is that assets are more fragile and precious than information. Assets are money. In the process of information digitization, it is easy to put information on the Internet, but for assets, this does not work, because behind the assets are real interests.

The third point: Compared with assets and information, assets have very high security requirements, and many problems must be faced, including attacks by hackers, competitors, fraud, etc. These are all linked assets. issues that need resolving. This is the third difference between assets and information. If there is a dispute over assets, they need to be resolved. In reality, it can be resolved by the court, but if it is on the Internet, it is difficult to deal with it.

The three characteristics of assets mentioned above are difficult to solve through traditional Internet methods. At the same time, the development of the Internet has made people lazier and lazier. If 10 years ago, many people could accept that asset connection would take a long time, but now it is difficult for people to accept it. For example, in order to sign a contract, it takes two to three days. It takes weeks to mail, and it costs a lot to go in and out of many traditional institutions frequently in order to make a cross-border payment. And compared with the connection method 20 years ago, the current Internet connection has become much more difficult, because many people find that after information is connected, the data becomes very valuable. What to do if it is valuable? The only way is to sink the value. When it sinks, it becomes a deep well of value. The larger the scale, the deeper the value. At the same time, another problem will be formed called data island. These issues need to be considered and resolved by the judicial chain.

Now, the court is standing at a historical opportunity node and has the opportunity to become a basic component of data generation and completion of connections. Disputes will inevitably occur over assets, and after a dispute occurs, the court will conduct a full-link review. This is a unique value, the value of the last mile of the Internet. By connecting assets, breaking data islands and value wells, this is the real value completion. This model actually belongs to small and medium-sized enterprises, including For individual users, the above is the value basis of the judicial chain.

If there is an island of value and it needs to be connected, there must be various connection methods. There are four main ways to connect.

The first is not to connect. , put it in a bank safe;

The second way is a bad connection, that is, through technological leadership and inequality, depriving the ownership of data assets through hacking technology, when there is no legal When connecting, bad connections must exist;

The third type is a connection that seems to be a good connection, but is actually a fragile connection. Nowadays, there are many ways to connect. When the market situation is relatively good, it is a bubble. When it is relatively large, it has a certain market, but once it encounters real value, it breaks down;

The fourth type is the judicial chain, which can be summarized in 15 words, that is, the whole process is recorded, the whole link is credible, and the whole node witnesses.

How can the judicial chain be technically credible and institutionally credible at a low cost?

First of all, the first problem is that assets are fragile, so when connecting assets, they must have the basic characteristics of real security. Security includes privacy protection, which is not a simple matter. The first day Alipay was born started with secured transactions, solving the problem of the authenticity of previous transactions between buyers and sellers. Later, based on Alipay, Sesame Credit was proposed, and many Everyone has Zhima Credit points, and through past credit records, big data and artificial intelligence are provided as a reference for whether the user can fulfill the contract, making real security a step further. Next comes the blockchain. The blockchain provides a very important capability, that is, the truth cannot be tampered with, which makes trust a big step forward in the level of real security. Therefore, the first problem solved by the judicial chain is to ensure that the bottom connector is real and safe when connecting assets. This real safety is not something you talk about in words, nor is it a technology in a laboratory, but a technology in a laboratory. It has been recognized by users, tested by the market and tested by large-scale business volume.

The second question is very critical. When everyone is connected through a real and secure connector, once the data assets are compromised, how to deal with disputes? The judicial blockchain has been moving in this direction in the past two years. By bringing notary offices, judicial appraisal centers, and courts to the bottom of the judicial chain, the data is authenticated accordingly, ensuring that once a dispute arises about data assets, it can be dealt with fairly and effectively. This is a very powerful system, which is the fundamental reason why the judicial chain is the real solution to the problem of the last mile of the Internet. So far, the judicial chain has ensured technical credibility and institutional credibility.

The third problem is that in the interconnection of assets, the cost of connection cannot be too high. Users have developed the habit of obtaining countless information with just a click of the mouse and a search button. Blockchain has been popular for many years, but so far there are less than 20 million real users, and the daily activity is very low. The first reason is that it is too difficult to use, and the second reason is that the cost of use is too high. Therefore, when connecting assets, it must be very simple, very easy to use, and low cost. Just like when Alipay first implemented real-name authentication, it could quickly complete user payments through face scanning, and at the same time, the security level was very high. Therefore, real connectors must have the characteristics of low cost and high applicability.

The judicial chain has achieved technical credibility and institutional credibility, and the cost of connection is not high, opening a new era of blockchain for asset connection.

The Hangzhou Internet Court’s judicial blockchain makes the entire process of electronic data generation, storage, dissemination, and use trustworthy. through the wholeThe complete structure can solve the entire life cycle of electronic data generation, storage, dissemination and use on the Internet, especially the whole-process trust issue at the generation end.

The blockchain consists of a three-layer structure:

1). The first is the blockchain program. Users can directly record the entire process of operation behavior in the blockchain through the program. , such as online submission of electronic evidence such as electronic contracts, rights protection processes, service process details;

2), The second is the full-link capability layer of the blockchain, which mainly provides real-name authentication, electronic signature, time Stamping, data storage and trusted services throughout the blockchain process;

3), the third is the judicial alliance layer, which uses blockchain technology to integrate notary offices, CA/RA institutions, forensic identification centers and The courts are connected together in the alliance chain, and each unit becomes a node on the chain.

The electronic evidence platform launched on the judicial chain of Hangzhou Internet Court directly establishes a special data channel between evidence and trial, making the collection, fixation, transmission and use of evidence more convenient and efficient.

In the past, when going to the Internet Court for litigation, evidence was submitted electronically and then uploaded to the "Hangzhou Internet Court Litigation Platform" (www.netcourt.gov.cn). For example, notarized documents are usually uploaded by scanning. The electronic evidence platform launched today first has a long "tentacle", and it can achieve seamless connection with other electronic data, such as notary offices. Then the notarized documents can be uploaded to the electronic evidence platform with one click and used directly as litigation evidence. For example, in transaction disputes involving e-commerce platforms such as Taobao and JD.com, mutual financial platforms, and wealth management platforms, third-party data service providers (such as operator platforms, electronic contracting platforms, and certificate depository institution platforms) can also directly transmit electronic data. The electronic evidence platform effectively solves the difficulties faced by parties in collecting electronic data evidence on their own and greatly saves the economic and energy costs of producing and cross-examining evidence in court trials.

The "electronic" evidence that was originally just scanned or typed has truly transformed into "electronic evidence". Through the third-party storage platform, "electronic data" is easily lost and tampered with. The magic spell forms a unique “data ID card” that cannot be tampered with, and is synchronized and backed up to the electronic evidence platform in real time. After entering the litigation process, the "data ID card" that has been saved on the electronic evidence platform will be automatically compared with the original electronic data to determine whether the electronic evidence has been tampered with later, thus ensuring the authenticity of the electronic evidence.

These electronic data have coded ID cards, which become the "elements" of each case. The platform classifies these elements and then matches them to each case. In this way, the system automatically matches elements, i.e. electronic evidenceImport each case to form a system that automatically files the case without a judge. We can imagine that we will soon be able to achieve a case filing speed of tens or hundreds per minute.

Finally, when these evidences become electronic data and are stored on the platform, in addition to the Hangzhou Internet Court, which can carry out judicial use on the platform during the trial of the case, other relevant institutions (such as other people with permission) Courts, judicial appraisal agencies, notary agencies, filing agencies) can all retrieve relevant evidence from the platform in accordance with procedures, and the co-construction and sharing of resource data will also be achieved.

Taking the Shanghai Pudong Notary Office’s data storage platform that has opened up the Hangzhou Mutual Judicial Chain as an example, we will introduce the complete closed-loop process from the data protection platform to judicial litigation.

1. Register the business platform and perform real-name authentication

Enterprise A, a design company, opens the Shanghai Pudong Notary Office data storage platform page and completes real-name identity authentication after registration.

2. Original data storage

When design company A completes the design of a work and archives the original work data, it initiates a remote storage call through its own business system Interface, call the RESTful API of the notary office's data storage platform to complete the storage of the design work file HASH and related elements. The deposit certificate will also be sent to the Judicial Blockchain, Pudong Notary Chain and China Time Service Center simultaneously. After all are successful, a certificate of deposit with the corresponding LOGO will be obtained. The HASH fingerprint data of the work files that are completely consistent on each chain and platform shows the validity and non-tamperability of this certificate.

5. Log in to Hanghu Court to submit a complaint and verify the legality of the evidence

The judicial chain is a specific application case of Ant Blockchain BaaS. Ant Blockchain BaaS (Blockchain as a Service) is an open "blockchain as a service" platform based on the Ant Financial Alliance blockchain technology and Alibaba Cloud. It outputs blockchain as a cloud service, supports numerous business scenarios and on-chain data traffic, and is the foundation of industry blockchain solutions. Ant Blockchain BaaS is committed to building an open and collaborative platform to provide convenient services to enterprises and individuals around the world.

The above picture is the product map of Ant Blockchain, in which the technical architecture of BaaS is mainly divided into three layers:

1. The bottom layer is BaaS Core

The BaaS Core layer is based on a cloud resource management platform that provides flexible support for hosts and containers, enabling convenient cross-platform operation and deployment. For trusted hardware, that is, the Shenlong server based on Alibaba Cloud provides corresponding hardware services and can provideProvide a trusted execution environment with high reliability and high privacy protection. In addition to the certificate deposit platform and smart contract platform, heterogeneous chain cross-chain services will be launched soon on the basis of homogeneous chain cross-chain services. In the current market, a single chain or a single chain has its own limitations. In the future, cross-chain technology will become a very important part of establishing trust infrastructure and a mutual trust ecosystem. At present, the BaaS platform has achieved internal interconnection through cross-chain services. It can also access trusted data sources on the external Internet through smart contracts and cross-chain services. In addition, BaaS Core has corresponding functions and support for other basic capabilities, such as alliance management, security and privacy, certificate key management, etc. While providing the self-developed Ant blockchain system, the BaaS platform also supports open source systems to better meet the diverse needs of customers, including enterprise Ethereum Quorum and Hyperledger Fabric.

2. The upper layer is BaaS Plus

The BaaS Plus layer encapsulates and services the underlying services and capabilities, and opens them into standardized interfaces to provide partners with access and use. This can greatly reduce customers' investment in basic resources and significantly shorten the time it takes to access services. So far, the platform has launched services such as trusted certificates, universal traceability, real person certification, and enterprise certification, and will gradually launch more services in the future.

3. The top layer is the BaaS Marketplace and solutions

Ant’s many partners can provide their capabilities in the marketplace. At the same time, practical applications implemented in different scenarios will precipitate a set of standard application solution templates, making it easier for customers to learn from the platform capabilities of other similar scenarios in their own applications. The Pudong Notary Office data storage platform can become a member of the BaaS Marketplace.

1. Account system

All transaction operations on Ant Blockchain are carried out around the account system, so before sending and executing transactions, you need to ensure that you have created a corresponding transaction in Ant Blockchain account, and then you can use the created account to submit transactions, and you can also complete modifications to the relevant account configuration based on the account structure.

The specific account data structure model fields and descriptions are as follows:

Among them, accounts contain three types of keys:

Ant Blockchain adopts the account It is implemented in a decoupled manner from the key, which to a certain extent prevents security risks such as data loss on the chain caused by key loss. The main account operations supported by Ant Blockchain include:

2. Privacy protection

Ant Blockchain supports the privacy protection capabilities of sensitive account information data by introducing some features of cryptography. , by extending relevantThe instruction function is used to implement the encrypted storage and addition and subtraction operations of the amount in the smart contract. Only individuals who obtain a valid key can decrypt the sensitive data in the smart contract and view the original amount information.

At present, the cryptographic features introduced by Ant Blockchain include zero-knowledge proof, that is, by introducing zero-knowledge proof, the legality of the transfer amount can be proved under the condition of encrypted ciphertext.

3. Cross-chain services

Ant Blockchain cross-chain service is an on-chain data service provided for smart contracts. This service deploys cross-chain services in the customer's blockchain environment. Contract/chain code, and provides an API interface for user contracts/chain codes to call and use. The cross-link service currently provides two types of services: ledger data access and contract message push, and their corresponding API interfaces. The ledger data access service can help user smart contracts obtain data on other blockchain ledgers, including but not limited to block headers, complete blocks, transactions, etc. The contract message push service can help communicate messages between smart contracts on different blockchains that have deployed cross-chain data services, satisfying scenarios such as cross-chain business association processing.

On May 22, 2019, Shanghai No. 1 Intermediate People's Court, Hangzhou Internet Court, Hefei Intermediate People's Court, Suzhou Intermediate People's Court, and Wuhu, Anhui Province jointly signed a letter of intent for cooperation, and will use the Hangzhou Internet Relying on the court's judicial blockchain platform, the four places are interconnected and jointly build the Yangtze River Delta judicial chain, creating a judicial-level trust mechanism with "full process records, full link credibility, and full node witness" to jointly promote judicial integration in the Yangtze River Delta region. develop. It was introduced at the meeting that the judicial blockchain operating mechanism of the Hangzhou Internet Court has become increasingly mature, and has collected 390 million pieces of electronic data. The dismissal rate of relevant cases has reached more than 96%. In intellectual property protection, financial risk prevention, agricultural product traceability, credit system construction, etc. played an important role.
The technology provider of the judicial chain of Hangzhou Internet Court is Ant Financial Blockchain, which has the world's leading core patented technology, 20,000 TPS high-performance certificate storage capabilities, extremely high privacy security protection capabilities, and top-level security Prevention and control capabilities protect the judicial chain. Its Ant Blockchain trusted certificate storage platform supports third parties to access the judicial chain.

For example, in terms of specific aspects, the judicial chain has greatly improved the effect of users' rights protection. For example, in China, copyright protection is very backward. For example, only 5% of the pictures are genuine, and the rest are pirated. However, from the filing of the case to the trial, the first instance takes 8 months, and the compensation obtained is only 500. -600 yuan, but the time cost and economic cost far exceed the compensation amount. However, the emergence of the judicial chain can reduce the cost of rights protection by one to two orders of magnitude. Secondly, the judicial chain can enhance the trust of the brand. On the one hand, it enables enterprises to stand together with the judicial chain and the brands and platforms recognized by the government. On the other hand, it allows enterprises to clearly and transparently tell their business models through trust connection. users, giving users a very strong sense of trust. Entrepreneurs, in particular, can have huge traffic in the early stages. Finally, the judicial chain solves the problem of the last mile of the Internet, which greatly reduces the user's cost of use. Therefore, using the judicial chain model really upgrades the traditional business model into a trust business model.
