⑶ [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.
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 greatly reduces the cost of offline evidence storage and collection, and improves the judgment process.The efficiency enables many cases that were previously unworthy of prosecution due to the high cost of rights protection to be better protected through the blockchain; the judicial chain solves the problem of low judicial service efficiency, realizes the integration and sharing of judicial data, and breaks down data islands; The judicial chain promotes the construction of the social credit system, reduces judicial costs, uses technology as the 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 real, 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. WhenWhen parties 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, 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, 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 requirements for linking assets. solved problem. 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. It has a certain market when it is relatively large, 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 record, the whole chain The road is trustworthy and witnessed by all nodes.

How does the judicial chain achieve technicalWhat about one that is technically credible and institutionally credible, and the cost is not high?

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 last mile problem 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 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 directlyThe program records the entire process of operational behavior in the blockchain, such as online submission of electronic evidence such as electronic contracts, rights protection processes, service process details, etc.;

2), the second is the full-link capability layer of the blockchain , mainly provides real-name authentication, electronic signatures, timestamps, data storage and trusted services for the entire blockchain process;

3), the third is the judicial alliance layer, which uses blockchain technology to Notary offices, CA/RA institutions, judicial appraisal centers and courts are connected together in a consortium chain, with each unit becoming 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 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, the platform canIn addition to judicial applications in Taiwan, other relevant institutions (such as other people's courts, judicial appraisal institutions, notary institutions, and filing institutions with permission) can retrieve relevant evidence from the platform in accordance with procedures, and the co-construction and sharing of resource data will also 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, 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 chain has its own limitations. In the future, for the establishment of trust infrastructure and mutual trust ecology,Cross-chain technology will become a very important part of it. 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, the account contains 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 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.

Currently, the cryptographic features introduced by Ant Blockchain include zero-knowledge proof, that is, by introducing zero-knowledgeIdentification proof is used to prove the legality of the transfer amount 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 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 received 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 allows 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.

⑷ Why blockchain investment must not just listen to "actors"

Yesterday, the Boao Asia Blockchain Forum attracted widespread attention. It is not that technology research and development and application design have achieved important results. As a result, it was just because the performances of the special actors on the forum were criticized.

For investors, although blockchain technology will have better development prospects in the long term, if you want to invest in blockchain, you still have to fully Consider the corresponding risks.

Ordinary investors who follow the trend of investment need to pay attention to the fact that many so-called investment projects are actually nothing more than pyramid schemes in the name of "blockchain". If ordinary investors enter rashly, they are likely to In the end, they were either "cut off leeks" or fell into a pyramid scheme.

To put it bluntly, blockchain investment must not just listen to the "actors".

⑹ With 1,400 crypto companies such as Binance and Huobi settling in, what is Dubai’s attraction?

Cailian News Agency | Blockchain Daily (Hangzhou, reporter Xu Cihao), a few days ago, Saudi Arabia Arab announced that it will invest $6.4 billion in the Metaverse and blockchain technology.

In fact, the United Arab Emirates, also a major oil country, has always been one of the countries in the world that supports and embraces blockchain the most, and Dubai in the United Arab Emirates has become one of the gathering places for blockchain companies.

According to local news reports in the UAE, the digital economy contributed a total of approximately 100 billion dirhams ($27.25 billion) in 2021, accounting for 4.3% of the UAE’s GDP. The country is home to more than 1,400 blockchain and crypto startups with a combined valuation of AED 90 billion ($24.5 billion). More than 90 investment funds and 12 business incubators are also supporting the country's digital industry, according to government data.

Industry insiders analyzed to the reporter of "Blockchain Daily" that blockchain, as a new technology, is treated differently in different parts of the world; and Dubai has attracted global blockchain companies through its open policy. and talents, taking the lead in the future development of the blockchain industry.

1,400 crypto companies have settled in

The United Arab Emirates, referred to as "UAE", is a country consisting of Abu Dhabi, Dubai, Sharjah, Fujairah, Umm Al Quwain, A federal state composed of seven emirates, Ajman and Ras Al Khaimah. The United Arab Emirates is known as the flower in the desert due to its rich oil production.

But oil countries also have a sense of crisis, that is - oil resources are not inexhaustible, and the flowers in the desert will wither. They must find new opportunities for wealth.

The blockchain and encryption industries represented by Bitcoin have given some small countries, including the United Arab Emirates, Saudi Arabia, and El Salvador, new vitality.

Dubai, in the United Arab Emirates, is on its way to becoming a Bitcoin trading center. Binance, ALPEX, Metahero and hundreds of companies (including more than 90 investment fundsand 12 business incubators) have chosen Dubai as their operations center.

In 2021, China has launched a round of rectification of virtual currency mining and trading. Many Chinese blockchain and crypto-asset companies have also moved to Dubai to seek compliance operations there. These include Huobi Exchange, Hufu Exchange, coinw Exchange, etc., which have completed the withdrawal of users in mainland China by the end of 2021.

A reporter from "Blockchain Daily" learned from relevant sources in Huobi that Huobi currently has an office in Dubai, which has domestic employees and local employees.

"Dubai has always been very active in its policies towards blockchain companies." The above-mentioned Huobi official told reporters.

In addition, on December 20, 2021, the cryptocurrency exchange Binance signed a cooperation agreement with the Dubai World Trade Center Authority (DWTCA) to jointly promote the establishment of a new international crypto-asset ecosystem in Dubai.

An anonymous exchange insider told the "Blockchain Daily" reporter that in view of Dubai's current open policy for exchanges, they are also actively seeking Dubai's virtual asset trading license. The timing Operations will be moved there when mature.

Due to the UAE’s open policy towards cryptocurrency, it has attracted many companies to settle here. According to local news reports in the UAE, the digital economy contributed a total of approximately 100 billion dirhams ($27.25 billion) in 2021, accounting for 4.3% of the UAE’s GDP. The country is home to more than 1,400 blockchain or crypto startups with a total valuation of AED 90 billion ($24.5 billion).

Dubai's open policy

"Blockchain Daily" reporter learned that the supervision of Dubai's cryptocurrency is governed by FRSA (Financial Services Regulatory Authority), SCA (UAE Securities and Commodities Authority) ) and DFSA (Dubai Financial Services Authority) completed.

In order to provide encryption services in the UAE or Dubai, a license is required from the SCA or FRSA (depending on the location of operations). Trading of cryptocurrencies is regulated by the SCA and FRSA, and licenses may be granted depending on the cryptocurrency nature of the transaction.

At the end of 2020, the UAE Securities and Commodities Authority (SCA) issued the "Decision No. (21/RM) of 2020 of the Chairman of the Authority on the Regulation of Crypto-Assets".

The regulation aims to establish a clear licensing regime for any provider wishing to provide crypto-asset services in the UAE. This includes initial token issuances, exchanges, marketplaces, crowdfunding services based on or utilizing crypto-assets. financing platform, custody services and related financial services.

The Crypto Regulatory Decision states that providers wishing to offer crypto asset services (or any related services) must be based in the UAE or in one of the UAE’s financial free zones (i.e. Dubai International Financial Center or Abu Dhabi than the global market),Permission from the SCA must also be obtained. As part of the process, applicants must demonstrate that they will strictly comply with the UAE’s anti-money laundering and counter-terrorism financing laws, cybersecurity compliance standards and data protection regulations.

Dubai’s Blockchain Layout

Marwan Alzarouni, CEO of Dubai Blockchain Center, told the media that the UAE, especially Dubai, has always been forward-looking and proactive in any future technology. Rapidly evolving, cryptoassets and blockchain are no exception.

As early as 2013, the UAE launched the "Smart Dubai Initiative" (Smart Du initiative). The core part of the plan is to improve government efficiency through the use of blockchain technology, including promoting blockchain through its own actions. The development of the chain from 1.0 (payment tools) to 2.0 (financial industry applications) and then to the 3.0 stage (applications in other industries and government affairs management) is committed to making Dubai a global leader in this field.

In 2016, Dubai established the Global Blockchain Council, which currently has more than 30 members, including government entities, international companies and blockchain startups. Technology giants such as Microsoft, SAP, and Cisco are all members of this committee.

The Global Blockchain Committee held an industry theme meeting in 2016 and announced 7 new blockchain proof-of-concepts, including: medical records, secured jewelry transactions, ownership transfers, business registration, digital wills, Tourism management, improved freight transport. It can be said that Dubai is currently the blockchain R&D center in the Middle East.

In 2017, the Dubai government announced that Emcredit, a subsidiary of Du Economy, would cooperate with the US-based startup Object Tech Grp Ltd to create an encrypted digital currency called emCash.

In 2018, Dubai Prime Minister Sheikh Mohammed announced that the Dubai government will use blockchain technology in half of its government businesses by 2021.

In 2020, in line with the vision of "Du Blockchain Strategy 2020", Smart Dubai (Smart Du) fulfilled its promise of establishing a prosperous blockchain ecosystem in Dubai, Launched numerous use cases, a joint blockchain platform and Dubai blockchain policy. Government and private sector agencies are working on 24 blockchain use cases. These use cases cover eight sectors, namely finance, education, real estate, tourism, business, health, transportation and security.

The UAE has reportedly completed a digital KYC project called Emirates Pass, which will enable users to interact with all aspects of the legal process from remote locations, and is already building on its judicial notarization and Using blockchain technology in certification servicestechnique.

The UAE has also proposed a plan to transform Dubai into the world's first city driven entirely by blockchain technology - the "Dubai Blockchain Strategy", making Dubai the happiest city on earth.

Hu Jie said that blockchain, as a new technology, is still in the stage of exploration and accumulation around the world. Dubai has adopted an open policy to attract blockchain companies and talents from around the world. In the future, blockchain Taking the lead in the development of the chain industry.

⑺ 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,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 and promote Zhejiang to become a national Digital government model 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.

⑻ Blockchain can be defined

On March 12, 2018, the Hangzhou Municipal Science and Technology Commission, Hangzhou Financial Work Office, Xiaoshan District People’s Government, and The second All Things Growth Conference co-sponsored by Hangzhou Daily Newspaper Group and hosted by Hangzhou Venture Capital Association and Hangzhou Bank was held in the press conference hall of Hangzhou International Expo Center. Babbitt and Bytom founder Chang Chai gave a speech on "The Future Can Be Predicted, Blockchain Can Be Defined" keynote speech.
The following is the content of the speech:
Good morning everyone, I am very happy to be invited to do such a sharing. The theme I shared is "The future can be predicted and blockchain can be defined."
I used to be a science fiction writer and wrote some science fiction novels in college. At that time, science fiction was still a very niche group and very few people read science fiction novels. Later, I had a post that is now very popular. In 2011, a college student asked on Zhihu: If you have 6,000 yuan for investment and financial management, what advice do you have? The advice I gave him at that time was to buy Bitcoin. . Now it seems that this is a piece of advice worth 20 million. Of course, it is a sad story because the subject did not buy Bitcoin in the end. It is also a sad story for me, because many people in the novel I wrote I haven’t read it, but this advice is often mentioned. In recent years, people have been sending me private messages asking me which coins to buy. However, I am not an expert in investment and financial management. Our company is engaged in blockchain.
Babit established the website in 2011 and established the company in 2014, so we may be the first batch of blockchain companies in China. On what basis do we judge that blockchain technology may be popularized or survive in the future?
This would like to mention a science fiction novel I once wrote in college called "The Art of Slaying Dragons". This computer-themed novel was written in 2007. It tells the story of hackers who can use huge amounts of computing resources on the Internet in the cloud era to complete some very grand scientific computing projects. After this novel was published at the time, it was criticized by many readers. They think this novel seems unreal and doubt that hackers' abilities are beyond ordinary people's imagination.
But now it seems that this novel is not an exaggeration at all. Why? Because in the cloud era, the abilities between people will be disproportionately amplified. In reality, the abilities between people may not be exaggerated.It is a normal distribution, just like a person's height and weight. However, on the Internet, people's abilities and influence will be disproportionately amplified. It is a combination of the Matthew effect + the long tail effect. body.
The core ideas of this novel are two points. The first point is that cloud computing will amplify people's abilities, and the improvement of computing power will amplify people's abilities. The second point is that computing is power. So when a new thing like Bitcoin comes out, it seems that the world written in my novel is becoming a reality. When Bitcoin was introduced to China from 2008 to 2010, many people had already heard of Bitcoin, but did not pay attention to it. In fact, to understand a thing like blockchain, some knowledge background is needed.
In addition, I would like to introduce a book, which is "Out of Control" written by Kevin Kelly. This book was written in the 1990s, but this book is very forward-looking and has a chapter that introduces the development of cryptocurrency. Pioneers, but these pioneers later became martyrs, what was the reason for their failure? In fact, blockchain needs to be based on three core technologies, and these three technologies are gradually maturing. The first technology is asymmetric encryption. In 1985, elliptic curve function encryption was already very mature, but unfortunately it was implemented in a centralized way. What are the risks of centralization? That is, when issuance If the currency company collapses or the founder is arrested, or the central server is attacked, it will cause the system to collapse, so it failed later. In 2000, someone began to introduce peer-to-peer technology into cryptocurrency for the first time, taking the lead in realizing distributed cryptocurrency. However, it also failed later. The reason is very simple, that is, there is no way to find a way to solve double payment (the same money is used). twice). It was not until 1997 that Adam Baker proposed proof of work. In 2004, Halfini expanded this technology into a reusable proof of work, so the 2008 Bitcoin white paper was successfully published.
And the carefully designed technical solutions in Bitcoin later seemed to be very advanced. For example, in 2014, Snowden revealed that elliptic curve function encryption is unsafe because the US National Security Agency has set up a backdoor in this encryption standard, giving the NSA an unknown method to weaken this curve. , at that time many people exclaimed that Bitcoin was dead and that the system might collapse, but later Satoshi Nakamoto did not use the encryption standard promulgated by the National Security Agency, but used a very rare curve.
To give another example, after hashing twice, a quantum computer cannot threaten the Bitcoin address and cannot decipher the Bitcoin private key from the address. What’s more interesting is that Satoshi Nakamoto also adopted a weird transaction method called a change mechanism. The change mechanism is that the remaining balance of each transaction is transferred to a new address. Now it seems that this is actually for the purpose of Prevent quantum computers, because the public key of a Bitcoin transaction will only be exposed on the blockchain during the transaction. You only need to transfer the remaining money to a new address during each transaction. In fact, you The public key will not be exposedon the blockchain.
So judging from so many details, it can be said that Satoshi Nakamoto is a bit like a person who is extremely careful, so many people think that he is not a person, but an organization.
I just mentioned why the proof-of-work mechanism was introduced to the blockchain and Bitcoin, and this cryptocurrency was successful? Because the proof-of-work mechanism is actually hash calculation. Why is calculation so important to the blockchain? ?I can give a very easy-to-understand proof through such a table.
This table shows that the real world and the digital world are actually in a mirror relationship. The real world can also be called the atomic world. In the real world, things are randomly distributed and random. In the digital world, everything is generally Pseudo-random. In the real world, there are no two identical leaves. Everything on the Internet can be copied. In the real world, it is a normal distribution. In the digital world, it is a power law distribution. It is the Matthew effect + long tail effect. . In the real world, things are competitive resources, which are exclusive resources. For example, if I own a microphone or a glass of water, others cannot own it. All resources in the digital world are non-competitive resources. For example, I transfer a document to another person, but in fact, this document cannot be transferred like a book in reality, because this document may be saved infinitely in my computer or other storage media. A copy, so based on such a mirror relationship, we can ask the question, why is it so difficult to copy exactly the same thing in the real world? This question can be turned into whether you can create a perfect crystal in reality, you can create A perfect crystal can actually copy exactly the same thing, but the third law of thermodynamics tells us that if you want to create a perfect crystal, you need absolute zero, and you have to invest a huge amount of energy. In turn, through this symmetrical thinking, we can This raises the question that in the digital world, that is, on the Internet, it is very difficult to prevent something from being copied and to achieve such competitive resources. To achieve such a competitive resource, a huge amount of personnel consumption is required, which is computing. The more computing power invested, the higher the barrier against double spending, which is why computing matters.
So since the real world and the digital world have such a mirroring relationship, the blockchain can actually be understood as the reverse machine of the printing press. I like to use such a very vivid metaphor to define the blockchain as the printing press. Reverse process.
Why is the printing press so great? In fact, before the birth of the printing press, human knowledge and information were competitive resources. Whether it was the Bible or martial arts secrets, they were all competitive resources. But after the birth of the printing press, this knowledge and Information has become a non-competitive resource that can be copied on a large scale, or the marginal cost of copying is almost equal to 0, so there is the subsequent information revolution. With the Internet, the Internet is actually an enhanced version of the printing press. But the problem with the Internet is that it is difficult to transfer competitive resources in the digital world, which is why 90The reason why some cryptocurrency pioneers in the 1990s failed was because blockchain solved this problem. It was the first to realize competitive resources on the Internet. The first competitive resource was of course Bitcoin, which was the first domino to be erected. One card. After the first card falls, we can imagine that the second and third cards will fall. As long as it has a value attribute, it is actually very suitable to use the blockchain for registration and circulation, because the Internet is suitable for it. It is a thing with information attributes, so we say that the Internet is an information transmission protocol and the blockchain is a value transmission protocol. All resources with value attributes are actually very suitable to be combined with the blockchain.
So I don’t think the blockchain will replace the Internet. The blockchain itself is a parallel world of the Internet. It is to do some things that the Internet cannot do, so it may propose many business models. In my opinion, it is not It is unrealistic. For example, it combines things with information attributes and business scenarios with blockchain. In fact, I think it is not that appropriate, because scenarios with information attributes are suitable for the Internet, and only scenarios with value attributes are suitable for "blockchain." +".
Let’s further deepen the mirroring relationship between the Internet and blockchain. The carrier of the Internet is often software, and the carrier of blockchain is generally protocols. Software needs to apply for patents to establish its own patent barriers. On the contrary, with blockchain, most blockchain projects are open source, and you are very welcome to copy it. The code does not need to establish such patent barriers or moats. The main body of software development is usually a company, and the main body of blockchain development is often a community or foundation, which is a very loose organizational form. Software requires constant iterative upgrades, but iterative upgrades of protocols are very difficult, so they are generally very stable, because protocol upgrades require the approval of the entire network consensus, which is of course very, very difficult. That’s why there are so many Bitcoins. The software can be maintained and updated, and the protocol is that it cannot be shut down after it is started, and it runs 24 hours a day. Based on this kind of thinking, we can solve many doubts in our hearts. For example, in 10 years ago, many experts or big names in the investment community believed that although Bitcoin was a pioneer, it did not necessarily have the last laugh. How to prevent being defeated by latecomers? This is a typical Internet thinking. Internet thinking regards Bitcoin as a software. Through technological upgrades, latecomers may catch up, just like the browsers in the 1990s. Later, the early browsers were defeated by the newcomers. But in fact, Bitcoin cannot be regarded as a kind of software, but a protocol. The method of implementing this kind of blockchain is already a minimum feasible solution, and there is not much room for optimization.
Many people understand blockchain as the fifth paradigm revolution, because it is based on the summary of technological updates in the past few decades, which means that such a paradigm revolution, a leap-forward revolution, will be completed approximately every two years. The 1970s were mainframes, the 1980s were PCs, the 1990s were the Internet, the 2000s were the mobile Internet, and the blockchain was born in the 10s. The trend behind this is actually a trend of decentralization. Mainframes are all developed in scientific research institutes.Institutes or military institutions, PCs have entered homes, the Internet has entered millions of people, mobile Internet has permeated every aspect of life, and blockchain has become more decentralized, without even a central server. There is another detail here, that is, the time of the blockchain was calculated from January 1, 1970. Why does it have such a feature? In fact, it is because many programming languages ​​are derived from Linux systems, and Linux is derived from mainframes. , so it has the imprint of such an era invisibly.
In fact, there is a deeper evolutionary law behind it, such as the three stages of asset evolution. The evolution of assets can be divided into three stages. The first stage is the confirmation of asset rights, which is the equityization of assets and the confirmation of asset rights. It can then be transferred as a whole, so it's kind of like the solid stage of the asset. The second stage is asset securitization. After securitization, the assets can be divided and transferred, and their liquidity is obviously stronger. It is a bit like the liquid stage of assets. The liquid stage also has its limitations. For example, the business requires a container. , this container is the platform for assets, and assets still cannot flow across platforms. Only after the assets are blockchainized, that is, after the assets are put on the chain, will they truly enter a gas phase, because everyone can manage assets through their own private keys, whether it is Equity, income rights, debts, intellectual property rights, etc., as long as they are assets with this value attribute, they are suitable for registration and circulation using the blockchain, so they are no longer limited by the platform, because everyone can complete it through their own wallet. The process of asset transfer does not require a centralized authority or a centralized trading place. More broadly, many people have summarized the stages of blockchain evolution. The first stage was in 2009 with Bitcoin as the Representing the stage of cryptocurrency to solve value transfer matters, it can be understood as the 1.0 of blockchain. In 2017, the era of issuing virtual assets through smart contracts emerged, represented by Ethereum, which can be understood as the 2.0 of blockchain. We believe that we will enter the third stage in 2020, using smart contracts to issue physical assets or help real assets to be put on the chain. The blockchain will eventually move away from the virtual to the real and serve the real economy. So Babbitt is doing the third stage, which is our prediction of the future development trend of the blockchain.
