Application of blockchain in access control

1.

(1) The underlying platform of the blockchain is a domestic independent and controllable blockchain platform developed by the science and technology of the blockchain. With the characteristics of high performance, high availability, scalability, easy operation and maintenance, strong privacy protection, and hybrid storage, the platform cooperates with the data sharing and security computing platform bitxmesh, the blockchain open service platform filoop, the supply chain finance platform filolink, and other platforms The deposit service platform filoink and the smart contract security R & D platform meshsec can better support the applications of enterprises, governments, instry alliances and other instries, and promote the efficient circulation of value among multiple institutions

(2) JD chain is the underlying framework of enterprise level blockchain independently developed by JD, and its birth marks that JD has started the construction of "Zhizhen ecology" based on the baas platform of blockchain and the underlying chain of "jdchain". Relying on the "one key deployment" capability of multiple optimization implementation, JD Zhizhen chain service platform has achieved the leading second level blockchain node deployment. In addition, it also has the core advantages of open compatibility with a variety of underlying, enterprise level dynamic networking and other mature applications. The timely launch of JD Zhizhen chain will effectively promote the large-scale implementation of enterprise level blockchain applications in various instries, and promote the construction of China's and global trust economy

(3) thunderchain is a blockchain application project independently researched and developed by netxin technology under thunderchain, which has high concurrency and second level confirmation capability of millions of TPS. Based on the research and development of high-performance blockchain procts, Xunlei has built an open platform of Xunlei chain, which helps enterprises or indivial developers to deploy smart contracts, easily realize the proct and service on the chain, and make the application development of blockchain more convenient

(4) Jingtong blockchain

Jingtong blockchain is the core underlying technology of Jingtong technology's blockchain with independent intellectual property rights. It is an effective decentralized Internet trading network based on blockchain technology, which adopts layered design (5 layers) underlying platform and multi language intelligent contract system, and has realized cross chain function. It has multi-level, all-round and one-stop service capabilities such as private chain, cloud chain and alliance chain. The layout of instry and regional ecology has taken shape

in addition to the above blockchain procts, there are community led LTC, cosmos, iota, Neuros, nuls, MOAC, etc., and enterprise led ripple, stellar, Weizhong bcos, network xuperchain, Huawei, Ping'an, Wanxiang, ant financial services, Zhongan, Bubi, matrix element, secret ape, zhongxiangbit, complex beauty, Shanghai Lianjing, etc

extended data:

blockchain is far more than a technology, which involves the spirit of "multi-party cooperation". In modern society, a lot of things must rely on everyone's cooperation to achieve 1 + 1 & gt; But we should try our best to avoid the problem of "information asymmetry" in cooperation

therefore, members of the alliance should keep accounts and share data together, and make everything public to eliminate "information asymmetry", so as to protect everyone's interests and make the business environment develop healthily. Honest work will get e benefits, if cheating will naturally be known to all. Technology is the foundation to help achieve this pattern. This is the more important "blockchain thinking"

2. The traceability and transparency of logistics instry and supply chain management can be effectively improved by using the characteristics of non tampering and distributed storage of blockchain technology information. Logistics is considered to be the area where blockchain is most likely to create value.

3.

The biggest feature of blockchain technology is decentralization, which will rece a lot of costs for the banking instry

First of all, decentralization means that the trust building mechanism between banking systems no longer needs intermediary, which saves the cost of intermediary

Secondly, the development of digital currency will realize the real-time digital transaction of banks. For example, in bill transaction, bank's bill transaction always relies on the third party to realize the transfer of valuable documents. Even for electronic bill transaction, it also needs the information of central bank's ECDs system for mutual authentication. The blockchain technology can realize the point-to-point value transmission, which no longer needs centralized system control. This not only speeds up the bill transmission speed, but also reces the mistakes caused by human factors. The rection of process will naturally rece the demand of the bank for personnel and save the labor cost of the bank

finally, it will also have an impact on clearing and settlement. The bank's clearing and settlement business has always been completed by the central settlement, with low efficiency. Settlement through blockchain technology will greatly improve the efficiency of banks

blockchain technology also plays an important role in the cross-border payment business of banks. Today, with the highly developed global trade, cross-border payment is becoming more and more frequent. Banks often act as third-party services in cross-border trade, such as electronic transfer, asset custody and so on. However, cross-border payment generally takes about two days to get to the account, which is inefficient and reces the utilization rate of funds in transit. In the blockchain technology, both sides of cross-border payment can complete through the point-to-point way, realize all-weather payment and real-time arrival, thus speeding up the speed of clearing and settlement, and improving the efficiency of bank business processing

another feature of blockchain technology is de risking. Banks can establish their own blockchain, which can ensure that the transaction information and transaction records of bank customers are true and effective, and will not be tampered with arbitrarily. Banks can effectively identify customers' information, understand all aspects of customers' situation, identify abnormal transactions of customers, and prevent being cheated by customers, So as to rece the cost of bank supervision

4. Blockchain application fields:
1. Financial field. Blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields. The application of blockchain technology in the financial instry can save the third-party intermediary link and realize the point-to-point direct docking, so as to greatly rece the cost and quickly complete the transaction payment< 2. Internet of things and logistics. Blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management. This field is considered as a promising application direction of blockchain

3. Public service. Blockchain is closely related to people's proction and life in public management, energy, transportation and other fields, but the centralization of these fields also brings some problems, which can be transformed by blockchain. The decentralized and fully distributed DNS service provided by the blockchain can realize domain name query and resolution through the point-to-point data transmission service between nodes in the network. It can be used to ensure that the operating system and firmware of an important infrastructure have not been tampered with. It can monitor the status and integrity of the software and detect bad tampering, And ensure that the data transmitted by the system using the Internet of things technology has not been tampered with< 4. Digital rights. Through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works, and ensure the authenticity and uniqueness of ownership. After the works are confirmed on the blockchain, the subsequent transactions will be recorded in real time to realize the full life cycle management of digital rights, and can also be used as a technical guarantee in judicial evidence collection. For example, mine labs, a start-up company in New York, developed a metadata protocol based on blockchain. This system called mediachain uses IPFs file system to realize right protection of digital works, mainly for right protection applications of digital pictures

5. Insurance. In terms of insurance claims, insurance institutions are responsible for fund collection, investment and claims settlement, and often have higher management and operation costs. Through the application of smart contract, there is no need for the applicant to apply or the insurance company to approve. As long as the claim conditions are triggered, the automatic claim settlement of the policy can be realized. A typical application case is lenderbot, which was launched by the blockchain enterprise stratumdeloitte and payment service provider lemonway in 2016. It allows people to register customized micro insurance procts through the chat function of Facebook messenger to insure the high value items exchanged between indivials, and the blockchain replaces the third party role in the loan contract< 6. Public welfare. The data stored on the blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision.

5. The story of blockchain and Chinese pork starts from Wal Mart. The retail giant recently opened a new "food safety cooperation center" in Beijing and will work with IBM and Tsinghua University to trace China's pork supply chain using blockchain technology
Wal Mart is looking at the potential of blockchain and hopes to use blockchain technology to help it trace food. China has the world's largest pork market, and its pork imports rose 76% in February, according to the Wall Street Journal. Wal Mart intends to cooperate with pork suppliers in China first. If it succeeds in pork procts, it will expand to other procts

most of the previous applications of blockchain were in the field of financial services, and this application in food supply will be an eye-catching case. Wal Mart is very concerned about the traceability of food and thinks that the tracking and records of China's food supply chain are not perfect. Gopinath said that traceability is the key. From slaughterhouse carcasses to packaged finished procts, if bar codes are pasted on every step and all handover work is recorded, the traceability of procts will be greatly improved, and consumers certainly want their food to be safe
this and European crowdfunding, the crowdfunding platform, make the perfect combination of digital currency and real assets by using blockchain technology, and make users' investment more secure.

6. What's your calculation power? Now, if you don't have 100g computing power, don't dig bitcoin. The money is not so easy to earn. And the difficulty of mining increases by 20% every 14 days

7. Let's take personal information security as an example, because the disclosure of personal information will cause great harm to informants, making them suffer from conservative harassment. What's more terrible is personal information leakage, which is usually accompanied by tens of thousands of personal information being stolen, illegally sold, and even using the formal data trading institutions to steal data. With the rise of jinwowo blockchain technology, the encryption of blockchain technology can provide solutions for the protection of personal information. Blockchain technology can store personal information in a distributed way to avoid the security risks faced by a single server.
