1. CreditEase Puhui: Promoting the normalized application of blockchain technology and empowering the development of financial technology

Recently, it was pointed out in the “14th Five-Year Plan” outline that, It is necessary to comprehensively promote blockchain technology innovations such as smart contracts, consensus algorithms, encryption algorithms, and distributed systems, focus on alliance chains to develop blockchain service platforms and application solutions in areas such as financial technology, supply chain management, and government services, and improve supervision. mechanism.

It can be seen that blockchain application innovation has officially become one of the national strategies and will definitely have a significant impact on the financial industry. Under such a situation, financial institutions are accelerating blockchain-related exploration and promoting blockchain technology to play a greater role in the financial field. Next, follow CreditEase Puhui to learn about blockchain-related knowledge!

What is blockchain

Blockchain is a chained data structure that combines data blocks in a specific order in chronological order. Records of all transactions since the birth of the system are stored. The data on the blockchain is jointly maintained and stored by nodes throughout the network, and cryptography ensures that the block data cannot be tampered with or forged. So the blockchain is essentially a distributed shared database.

Blockchain is an innovative application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms in the Internet era. It is an information technology solution that solves trust problems and reduces trust costs. . The application of blockchain technology can eliminate traditional trust intermediaries, subvert the old centralized model that has existed for thousands of years, solve the trust problem between strangers without the need for centralized trust intermediaries, and significantly reduce the cost of trust. Trust costs.

How blockchain can solve the pain points of supply chain finance

Supply chain finance is based on core customers, based on real trade background, and uses self-reimbursement trade financing. , which provides comprehensive financial products and services to upstream and downstream enterprises in the supply chain through professional means such as accounts receivable pledge registration and third-party supervision to close capital flows or control property rights.

The foundation of supply chain finance is the supply chain. The supply chain involves information flow, capital flow, logistics and business flow, and is naturally a multi-subject and multi-collaboration business model. In this case, if you want to carry out trade financing, you will first encounter many authenticity issues, such as the authenticity of the transaction and the authenticity of the documents, which require confirmation by multiple parties and consume a lot of manpower and material resources; secondly, the multiple entities involved , there is a problem of difficulty in interconnection. For example, the supply chain management system, enterprise resource management system, and even financial system used by each entity are different, making docking difficult. Even if they are connected, it will be difficult to share information due to inconsistent data formats and data dictionaries.

Characteristics of blockchain

1. Decentralization

The distributed structure of the blockchain means that data is not recorded and stored on a centralized computer or host, but allows everyone involved in data transactions to Nodes record and store all data information. To this end, the blockchain system uses an open source, decentralized protocol to ensure complete recording and storage of data. The blockchain has built a complete set of protocol mechanisms, allowing each node in the entire network to participate in recording data while also participating in verifying the correctness of the recording results of other nodes. Only when most nodes (or even all nodes) in the entire network confirm the correctness of the record will the data be written into the block. In the distributed structure network system of the blockchain, the network nodes participating in the recording will update and store all data in the entire network system in real time. Therefore, even if some nodes are attacked or destroyed, the data update and storage of this system will not be affected.

2. Unforgeable

The principle of blockchain recording requires all nodes participating in the recording to jointly verify the correctness of the transaction record. Since all nodes are recording every transaction in the entire network, once the information recorded by a node does not match that of other nodes, other nodes will not recognize the record, and the record will not be written into the block.

3. Non-tampering

It is almost impossible to change a certain block and the transaction information within the block. If this block is changed, every subsequent block will be changed. Therefore, anyone trying to tamper with the data must simultaneously invade at least 51% of the nodes participating in the global record and tamper with the data.

Mathematical encryption

Each transaction requires a valid signature before it will be stored in the block. Only valid digital keys can generate valid signatures. Keys come in pairs and consist of a private key and a public key. Among them, the public key is public, and the private key is only visible and used by the owner, and is used for transaction signatures to prove digital identity.

What are the advantages of introducing blockchain?

First, to solve the problem of information islands, multiple stakeholders can set rules in advance to accelerate data interoperability and information sharing;

Second, according to property rights law , Electronic Contract Law, Electronic Signature Law, etc., the accounts receivable certificates of core enterprises can be converted into transferable and bankable confirmation certificates through the blockchain, so that the credit of core enterprises can be transmitted along trusted trade links. Based on mutual confirmation, the entire certificate can derive various operations such as splitting and traceability;

Third, provide credible trade data, such as providing an online basis under the blockchain architecture Tightly structured and complete records of contracts, documents, payments, etc. improve information transparency and enable wearabilityTransparent supervision;

Fourth, achieve cost reduction and efficiency improvement. After the credit of the core enterprise is transferred, small and medium-sized enterprises can use the credit line of the core enterprise to reduce financing costs and improve financing efficiency;

Fifth, realize smart liquidation of contracts. Automatic clearing and settlement based on smart contracts reduces manual intervention, reduces operational risks, and ensures the safety of repayment.

CreditEase Puhui believes that blockchain supports commercial applications with high performance, high scalability, and high security, provides financial technology companies with multi-level data security and privacy protection, and supports automatic monitoring and failure Alerts help track all transactions that occur in the system and contribute to the healthy and orderly development of the financial technology industry.

2. What are the practical applications of blockchain technology

1. Financial field

Blockchain is used in international exchange, letters of credit, and stock rights registration It has potential huge application value in financial fields such as stock exchanges and stock exchanges.

2. Internet of Things and Logistics Fields

Blockchain can also be naturally combined in the Internet of Things and logistics fields.

Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved.

3. Public service fields

Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields, but the centralization of these fields Characteristics also bring some problems, which can be transformed using blockchain.

4. Digital copyright field

Through blockchain technology, works can be authenticated, prove the existence of text, video, audio and other works, and ensure the authenticity and uniqueness of ownership. sex.

5. Insurance field

In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs. Through the application of smart contracts, there is no need for the policy holder to apply or the insurance company to approve it. As long as the claim settlement conditions are triggered, the insurance policy can automatically settle claims.

6. Public Welfare Field

The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for social welfare scenarios.

3. Which countries have already invested blockchain technology in urban construction

Brazil, the United Kingdom, the United States, China, etc., Xiongan, a smart city, has many applications of blockchain Technology, platforms such as Babbitt Golden Finance Zhiqu Chain have many cases of blockchain information application. Zhiqu Chain starts from the heart

4. Is the bsn blockchain a national blockchain?

The bsn blockchain is a national blockchain.

On April 25, 2020, the Blockchain Service Network (BSN) was hosted by the National Information Center and co-organized by China Mobile Communications Group Co., Ltd., China UnionPay Co., Ltd., and the Blockchain Service Network Development Alliance. The commercial launch conference was held in Beijing.

The National Blockchain Service Network (BSN) announced that it has officially entered the commercial stage and launched an overseas version for public testing. This is the first time that BSN has officially entered the global commercial stage since it was officially released on October 15 last year and entered a six-month internal testing period.

Introduction to BSN

BSN is a blockchain public infrastructure. It encapsulates the operating environment, cloud resources, network communication and retrieval interfaces required for blockchain applications to form a complete set of one-stop solutions for blockchain application development, deployment and management. The BSN Alliance encourages enterprises or individuals to use the underlying capabilities of BSN to establish their own blockchain business models and serve their own customers.

In the "Blockchain Service Network Basics White Paper" written by the BSN Development Alliance, BSN is defined as a cross-cloud service, cross-portal, and cross-underlying framework for deploying and operating various blockchains Global infrastructure network for applications.

The initiator of BSN is not an ordinary private enterprise or a blockchain startup, but the National Information Center, a government agency under the National Development and Reform Commission. It also cooperates with state-owned communications such as China Mobile, China Telecom, and China UnionPay. The giants work together to build BSN, the national blockchain service network.

5. What disruptions does blockchain bring and why can it become a national strategy?

The disruptive characteristics of blockchain lie in the following four aspects: 1. Transparency. The data records of the blockchain system are transparent to the entire network nodes, and the update operations of the data records are also transparent to the entire network nodes. This is the basis for the trust of the blockchain system. Since the blockchain system uses open source programs, open rules and high participation, blockchain data records and operating rules can be reviewed and traced by nodes throughout the network, with high transparency.
2. Openness. The blockchain system is open. Except for the private information of the parties directly related to the data, which is always encrypted, the blockchain data is open to everyone (except for blockchain systems with special permission requirements). Anyone or participating nodes can query blockchain data records or develop related applications through public interfaces, so the entire system information is highly transparent.
3. Information cannot be tampered with. Once the information of the blockchain system is verified and added to the blockchain, it will be permanently stored and cannot be changed (except for systems such as private blockchains with special change requirements). Unless more than 51% of the nodes in the system can be controlled at the same time, modifications to the database on a single node are invalid, so the data stability and reliability of the blockchain are extremely high
4. Decentralization. Decentralization is the most basic feature of blockchain, which means that blockchain no longer relies on central processing nodes and realizes distributed recording, storage and updating of data. In a traditional centralized network, attacking a central node can destroy the entire system. However, in a decentralized blockchain network, attacking a single node cannot control or destroy the entire network or more than 5% of the nodes in the network. It's just the beginning of gaining control. 20192020 is the first year for the commercial application of blockchain technology, and favorable policy incentives will make the development of blockchain technology more stable.
As the application of blockchain technology gradually penetrates into many fields such as digital finance and the Internet, everyone has a clearer understanding of the value of blockchain.
Blockchain has formed a global competition situation. All countries are seizing development opportunities, and China cannot lag behind; therefore, it is understandable that blockchain has become a national strategy.

6. Does the country support blockchain?

As a new technology, countries around the world have corresponding policies to support its development, with a wide range of radiation - starting from this year It can be seen that more than half of the provinces and cities across the country have included blockchain in the 2020 government work report. In addition to first-tier cities such as Beijing, Shanghai, Guangzhou and Shenzhen, central and western cities such as Gansu, Ningxia, and Xinjiang have also joined the blockchain technology research and application camp. Developed cities in the east continue to play a leading role in technological research and application innovation; cities in the central and western regions adapt to local conditions and combine new technologies to accelerate digital economic transformation. Strong support - this year the Central Bank, the Ministry of Transport, the State Administration of Foreign Exchange, the State Administration of Radio, Film and Television, the Ministry of Justice, the Ministry of Agriculture and Rural Affairs, etc., have respectively proposed the use of blockchain technology to accelerate the development of applications in various fields. Many other provinces and cities have also continued to introduce new policies, most of which are special support policies for blockchain. It is expected to build more industrial parks and open up more government application scenarios. The direction is clearer - there are clearer details under the general direction of blockchain assisting the transformation and upgrading of traditional industries and empowering the digital economy. Application scenarios such as transportation, agriculture, intellectual property, and certificate storage have become the first batch of experimental directions. In terms of government affairs, it is an important breakthrough and has been implemented. Beijing City’s “innocent approval”, Jiangxi Province explores “blockchain + undocumented handling”, Fujian Province implements the “on-chain government affairs” project, and Gansu Province accelerates the construction of “Digital Gansu”. ”, Shandong and Hainan are all committed to e-government and other fields. It is foreseeable that the future blockchain e-government scenario is worth looking forward to. Legal basis: Article 3 of the "Blockchain Information Service Management Regulations" The National Internet Information Office is responsible for the supervision, management and law enforcement of nationwide blockchain information services in accordance with its duties. The Internet Information Offices of provinces, autonomous regions, and municipalities directly under the Central Government are responsible for the supervision, management and law enforcement of blockchain information services within their respective administrative regions according to their responsibilities. Article 4 encourages blockchain industry organizations to strengthen industry self-discipline, establish and improve industry self-discipline systems and industry standards, guide blockchain information service providers to establish and improve service specifications, promote the construction of industry credit evaluation systems, and supervise blockchain information service providers Provide services in accordance with the law, accept social supervision, improve the professional quality of blockchain information service practitioners, and promote the healthy and orderly development of the industry. Article 5 Blockchain information service providers shall implement information content security management responsibilities and establish and improve management systems for user registration, information review, emergency response, and security protection.
