1. Breaking 100 million in 6 months! Zhejiang Provincial Department of Finance and Ant Blockchain bid farewell to paper tickets
Zhejiang Online, January 15 (Zhejiang Online Correspondent Chen Jieqiong) In order to better solve the "run once problem", local governments are increasingly applying new technologies. Coming faster and faster. Recently, Ye Shibao, director of the Electronic Invoice Center of the Zhejiang Provincial Department of Finance, said in an interview that since the establishment of the provincial blockchain electronic invoice platform in June last year with Ant Blockchain, as of the end of 2019, 507 medical institutions in Zhejiang Province have been on the blockchain. , 74 public hospitals realized electronic bill reimbursement in other places within the province, 100 million fewer bills were issued, and more than 30 million bill printing costs were saved, once again at the forefront of innovation.
Interestingly, electronic bills have been promoted for many years but there are still many links that cannot be solved. Blockchain has become a key. It is understood that Ant Financial is the first company to explore the application of blockchain technology in digital government industries such as finance and taxation. Through Ant blockchain technology, electronic bills can be "stamped" throughout the entire process from generation, transmission, storage to use. The entire process is traceable and cannot be tampered with, ensuring that the authenticity of the bill can be quickly confirmed in every circulation link, thus Achieve cross-regional and cross-department settlement and reimbursement.
Ye Shibao said that according to previous statistics, the entire process used to take about 12 working days to go to the medical insurance department for reimbursement, while commercial insurance reimbursement took longer, taking 7-60 working days. Now you no longer need to hold the ticket and stamp it in several places, you can quickly receive it with just a few clicks on your mobile phone.
Zhejiang University Shaw Hospital is one of the first hospitals in the province to go online. For Zhao Yue, a bill administrator who has worked in the finance department for 30 years, this is also a good thing.
In the past, he manually reviewed half-meter-high stacks of receipt stubs every day, and packed a large box every eight days on average. The pile could not fit in the office, and he would ask his colleagues to move it to the warehouse for storage. After receiving it and then doing the write-off, "it will take several months to complete the entire process." Nowadays, fewer and fewer bill stubs are collected every day, from the original half meter high to ten or twenty. "The warehouse is no longer needed, and several vehicles that transport the bills for destruction have also been returned."
The full link between hospital electronic bills and reimbursement and claims has been opened up, ultimately improving the patient experience in the "last mile" of medical treatment. Taizhou Hospital dared to be the first to allow Mr. Pang, a local resident, to receive reimbursement without traveling for 7 hours at a time when he was on a business trip to Hangzhou for medical treatment. He became the first person in the country to realize the reimbursement of medical insurance in other places through blockchain electronic bills.
The changes in each hospital are just the tip of the iceberg. Subway ticket settlement on the chain allows users to pass with one code, Hangzhou Internet Court introduced the Ant blockchain, provident fund withdrawal, etc. Zhejiang Province has completed implementation in more than 26 fields. From mobile payment to digital economy, Zhejiang has always been ahead of the curve in the application of innovative technologies.
At the 2020 Zhejiang Two Sessions held recently, Jing Xiandong, a member of the Zhejiang Provincial Committee of the Chinese People’s Political Consultative Conference and chairman of Ant Financial, said that he will continue to use AI and blockchain to promote the upgrading of Zhejiang’s digital government affairs.level, promoting Zhejiang to become a national digital government demonstration province. In the future, only applications that benefit the real economy and the public will be truly valuable applications, and blockchain must fundamentally move away from virtuality and into reality.
2. Alipay launched a technology that makes “data available and invisible”, called Ant Blockchain Morse Computing
In the new era of business intelligence, a broad consensus has been formed: Data It is the most basic means of production, and the use of data by various industries and enterprises has also entered a mature stage. In the foreseeable future, the depth and breadth of data utilization will be further upgraded, entering the stage of cross-institutional and cross-industry data sharing, integration, and innovation, thereby opening up the magnificent picture of the Big Data 2.0 era: data connectivity covering government, commercial institutions, and individual departments. Sharing is a vertical and horizontal trunk line based on industrial chain data connection and peer data cooperation, and is used in many fields such as finance, marketing, public services, medical care, and scientific research. Richer and multi-dimensional data resources create a multiplier effect, breed greater data value, open the door to business innovation, and thus bring more inclusive benefits and convenience to users.
Although there is a strong demand and willingness for data cooperation between institutions, in the specific cooperation process, due to obstacles such as business value, data security, privacy protection, and infrastructure, it is very difficult to implement data cooperation. In fact, Countless "data islands" have been formed. In the process of data cooperation and sharing, we mainly face the following problems:
Ant Blockchain Moss Secure Computing Platform aims at the above-mentioned pain points of data security trust, personal privacy protection and insufficient data infrastructure, adhering to the " Based on the principles of "data is available and invisible" and "moving computing to the data end", we use cutting-edge technologies such as blockchain, cryptography, privacy protection, secure multi-party computing, and trusted computing to build a secure, privacy-protecting, efficient, universal, and lightweight It provides a large-scale and decentralized data cooperation infrastructure to open up data islands, help institutions achieve safe, convenient and compliant data cooperation, and bring more convenience and benefits to users.
The Ant Blockchain Moss secure computing platform provides a new secure and privacy-protecting data cooperation method, which can pass passwords without leaking local data and keeping the original data out of the domain. Learning algorithms, distributed execution of predetermined logical operations and obtaining expected results, thereby completing data cooperation efficiently and safely. At present, Ant Moss has been widely used in joint financial risk control, rapid insurance claims settlement, people's livelihood and government affairs, multi-party joint marketing, multi-party joint scientific research, cross-border data cooperation and other fields.
Take credit business as an example. The first is the prevention and control of long-term lending. Data shows that for every additional institution a loan applicant applies to, the probability of default increases by 20%. However, the current credit reporting coverage of the central bank is limited, and more than 400 million natural persons lack credit reporting records; various credit institutions have spent time and money accumulating user credit data and are unwilling to share it with competitors; even if credit institutions are willing to share data, There are also many obstacles such as data security, user privacy, and compliance. With the help of Ant Moss,Multiple financial institutions can establish a risk control data alliance based on multi-party secure computing technology to confidentially share blacklists, credit applications, credit records and other data without leaking the original data of each institution, and obtain statistical results through distributed encryption calculations. Secondly, under the premise of user authorization, financial institutions can use Antmos to obtain massive multi-dimensional data from cross-industry governments, operators, e-commerce, independent data service providers, etc., to improve the accuracy of credit assessment models, thereby increasing the acceptance rate, Reduce bad debt rate. Combined with blockchain technology, Antmos also provides functions such as certificate storage, authorization, and billing for data service calls, improving the data alliance's commercial operations, cooperative management, supervision, and auditing capabilities.
Let’s take insurance claims as an example. Commercial insurance participants must collect relevant forms, medical receipts, medical records and other information after medical treatment, and then submit or upload them to the insurance company's claims platform. Only after approval can they obtain compensation. The entire claims process is long, inefficient, and There is a risk of fraudulent compensation. Many insurance companies hope to directly connect with hospital data and establish a fast compensation channel. However, hospitals are concerned about medical data security and patient privacy leaks, and are reluctant to directly open sensitive medical data. With the help of Ant Moss, secure computing nodes can be deployed in a distributed manner in the hospital domain and insurance company claims service domain, and the insurance company can remotely deploy the claim settlement model and adjustment rules on the computing nodes in the hospital domain. After the patient initiates a claim for medical treatment, the hospital-side secure computing node automatically uses the original medical treatment and prescription data of the claim applicant to perform local encrypted calculations to obtain the claim settlement result, and only outputs whether compensation and the amount of compensation are paid to the insurance company. In this way, a closed loop of business and data can be formed while protecting the security of medical data and personal privacy, greatly improving the efficiency and accuracy of claims settlement, and solving the pain point of "difficult medical treatment and more difficult claims settlement". The data summary and judgment results involved in the entire claims process can be encrypted and stored in the blockchain to facilitate subsequent profit sharing, auditing, and supervision.
Finally, take the field of government affairs as an example. With the help of Antmos, efficient and secure data sharing can also be achieved between departments and between government departments and the public. When building big data platforms in various places, there is no need to move all data from industrial and commercial, taxation, civil affairs and other departments to the platform. Instead, computing models or rules only need to be deployed in the data domains of each department, and encrypted calculations can be performed in real time according to business requests. Called in real time. The data demand department can quickly adjust and optimize calculation strategies and rules, and can feed back the calculation results to the original data department to provide improvement suggestions for data collection and sorting, thereby consolidating the data foundation for people's livelihood and government affairs, and realizing "multiple data" conveniently and securely. Don’t run around, people don’t have to run errands.”
Ant Moss relies on the Ant Financial Technology platform and combines blockchain technology to transparently and productize complex privacy protection and cryptography algorithms, providing secure release, security models, security statistics, and secure queries. , security scripts and other core functions. Ant Moss products have the following features and advantages:
• Data security: The underlying detailed data and original data of all parties involved in data cooperation do not leave the computing node. All calculations are performed in a ciphertext state, and the querying party can only obtain the results of the query and calculation.
•Transparent and trustworthy: Designed according to the open source idea, it ensures the security of computing and enhances mutual trust by disclosing algorithms. It has applied for more than 50 patents related to multi-party secure computing algorithms. In addition, Antmos has obtained security and privacy protection certifications from many domestic and foreign authoritative organizations such as the Ministry of Public Security, the National Information Technology Research Center and Trust Arc, and participated in the formulation of national security computing standards by the China Academy of Information and Communications Technology.
•Privacy protection: Minimize data utilization, all calculations are performed on encrypted or desensitized data, and all output is minimized, ensuring the security of personal privacy data to the greatest extent.
•Decentralized architecture: Using a completely decentralized architecture, data calculation and interaction are completed independently between multiple computing nodes. There is no central control node, which reduces trust costs and has stronger disaster tolerance. and anti-attack capabilities.
•Blockchain verification audit: Use blockchain technology to carry out certificate storage, authorization, billing, etc. of data service calls to ensure that data calculation and utilization are legal and compliant; provide verification of calculation data and processes Verification auditing, data monitoring and other functions ensure the authenticity and credibility of the calculation process, data authenticity and data quality.
Ant Moss looks forward to more partners joining in, achieving its own business growth through secure and compliant data cooperation, and providing secure data cooperation solutions with more industry attributes.

First of all, its technology is passable, and secondly, Ant Blockchain is considered early in the world in terms of blockchain technology. , it is normal to be selected. Last but not least, the international community will give our country a quota. The specific analysis is as follows:
1. The technology of Ant Blockchain is higher than other domestic ones of the same type.
There are not a few people working on blockchain in China. At least several large Internet companies have made related products, and each of them has received certain promotional information, and when they made it, they also had their own It attracted a group of people to register, but few people did it well. Not long after some people registered, they started to make other plans, and Ant Blockchain is one of the few products that can survive.
In general, it is expected that Ant Blockchain will be selected as the top internationalThis reflects not only technology, but also our users and our country, which are the strongest backing for this.
4. [One of the top ten blockchain government cases] Ant Blockchain-Hangzhou Internet Court Judicial Chain Case
According to Hangzhou Daily, on September 18, 2018, The Hangzhou 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.
Plaintiffs can submit electronic evidence such as contracts, rights protection processes, and service process details online through the online complaint portal, which will be submitted by notary offices, judicial appraisal centers, CA/RA institutions, courts, Ant Financial and other on-chain nodes. Joint witness and joint endorsement provide one-stop service for the prosecutor. 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 facilityIf it is not prepared, it becomes a copy and cannot be the basis for finalizing the decision. 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 content, you need to use responsive software to read and display it, which makes it difficult to demonstrate. It 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 original documents, 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, on the theme of "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 connections continue to changeAt the same time as the expansion, the quality of the connection has also undergone a very large change. This is called the second curve. The original object of the connection was information, but now it is likely to become an asset.
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, there is a fatal flaw, that is, it cannot be transmitted through copying. After the asset is given to a person, It cannot be given to anyone else.
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 to connect the mainThere are four ways,
The first way is not to connect, put it in the bank safe;
The second way is a bad connection, that is, through technical Leadership and inequality, depriving the ownership of data assets through hacking technology. When there is no legal connection, bad connections must exist;
The third type is a connection that seems to be a good one, but in fact It was a fragile connection, but now there are many ways of connection. They have a certain market when the market situation is relatively good and the bubble is relatively large, but once the real value is realized, it breaks down;
Chapter 1 The four types are 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. thereforeWhen 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 overall complete structure, it 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 the only “data ID card” that cannot be tampered with and implementsSynchronously back up to the electronic evidence platform. 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 The key element is to import electronic evidence into each case to form a system that automatically files cases 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 institutions, notary institutions, filing institutions) 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 enterprises and individuals around the world withProvide convenient services.
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, Alibaba Cloud's Shenlong server provides corresponding hardware services and can provide 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 method of decoding accounts and keys. It is implemented in a coupling manner, 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 the relevant command functions at the smart contract level to realize 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%. 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 protectionIt is very backward. For example, only 5% of the pictures are genuine, and the rest are pirated. However, the first instance takes 8 months to defend rights from filing to trial. The compensation obtained is only 500-600 yuan, but it takes a long time. The cost and economic cost far exceed the amount of compensation. 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.

7. In which fields has the traceability service of Ant Blockchain been applied?
As far as I know, the application of Ant Chain in traceability started with Tmall International in 2018. During Tmall’s Double 11 this year, Ant blockchain technology traced the origin of 150 million products to ensure authenticity. Now Ant Chain traceability is also possible under epidemic prevention and controlIt has played a huge role, such as "Zhejiang Cold Chain", a cold chain food traceability system first launched based on Ant Blockchain and Alibaba Cloud, which can realize closed-loop traceability management from the first stop of the supply chain to the smallest packaging of products in the consumer link, and master the cold chain Food supply chain flows.
8. How to view Ant Blockchain traceability
Ant Blockchain traceability still has certain development prospects.
Blockchain traceability should anchor the relationship between physical objects and the digital world, but each link can only operate on their own parallel lines, making it difficult to achieve absolute traceability. Moreover, the corresponding nodes of the Ant traceability blockchain solution can only be deployed on Alibaba Cloud.
It is fully managed by a third party of Ant Technology and cannot be deployed in upstream and downstream or industrial and commercial regulatory agencies, which further degrades the ability of decentralized anti-tampering. This solution should be a way of brand gain.
Overview of traceability services:
The Ant Blockchain traceability service relies on the alliance blockchain developed by the Ant Blockchain BaaS platform and is suitable for traceability scenarios. technology. Ant blockchain traceability service uses blockchain and IoT technology to track and record the circulation chain of tangible goods or intangible information.
Register data on product characteristics such as product quality information, logistics information, quality inspection information, etc. on the blockchain in a tamper-proof manner, solving the problem of information islands, poor information flow, and lack of transparency of information. Industry issues.
Ant blockchain traceability service establishes a special entrance for brand enterprise users and independent software vendors who have blockchain traceability needs, provides simple operation procedures and convenient back-end management, and guides them to quickly implement business To meet demand, we can increase brand credibility through blockchain, and at the same time combine marketing to accurately reach end users.
9. With this certification (ant blockchain traceability), does it really mean it is authentic?
No, it can only prove that the product has a traceable identification (ID). If you assume All counterfeit and shoddy products cannot obtain this logo, so all genuine products have traceable IDs.
And the binding between a traceability logo and a product is not unique and unbreakable! The key is that the logo is on the block, but the product is not! In other words, a logo can also be used for counterfeiting. Increasing the difficulty of marking can raise the threshold for counterfeiting, but it cannot completely eliminate it!
Blockchain can only protect digital assets. If you want to protect commodities, the higher the social cost, the more difficult it will be to overcome it. Because commodity protection requires relevant social investment. In fact, the fact that this matter is attached to the concept of block chain is pure speculation! There are no block chains, and the classic technology stack has many solutions for traceability identification!
Is blockchain + anti-counterfeiting traceability necessary?
Blockchain is a new application of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. It is a series of data generated using cryptographic methods.Blocks, each data block contains information about a change of hands or transaction.
It can be used in the food sector so that each party in the supply chain (producer, processor and distributor) can provide traceability information about their specific role (such as date, location, farm construction, distribution channels).
At present, among the many application fields of blockchain, blockchain food traceability and anti-counterfeiting is currently one of the most promising blockchain fields.
The reasons can be summarized in three aspects:
First, for consumers, this technology will meet their growing demand for food quality transparency;
< p>The second is that for food suppliers (breeders), this is a means to demonstrate the high quality and professionalism of their products;The third is that the technology is easy to promote and use, and the outer packaging of each product Each will include a QR code that consumers can scan using their smartphones, eliminating the need to purchase additional equipment.
