① What exactly is blockchain

What is blockchain?
Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system [1].
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. The blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
Blockchain was born from Satoshi Nakamoto’s Bitcoin. Since 2009, various Bitcoin-like digital currencies have appeared, all based on public blockchains.
The current situation of digital currency is that a hundred flowers are blooming. Here are some common ones: bitcoin, litecoin, dogecoin, dashcoin. In addition to currency applications, there are also various derivative applications, such as Ethereum, Asch and other underlying application development platforms, as well as NXT , SIA, BitShares, MaidSafe, Ripple and other industry applications.
On January 20, 2016, the People’s Bank of China Digital Currency Seminar announced that it had achieved phased results in digital currency research. The meeting affirmed the value of digital currency in reducing the issuance of traditional currency and stated that the central bank is exploring the issuance of digital currency. The expression of the People’s Bank of China’s Digital Currency Seminar has greatly enhanced the confidence of the digital currency industry. This is the first time that the five central bank ministries and commissions have expressed a clear attitude towards digital currencies since they issued a notice on preventing Bitcoin risks on December 5, 2013. [4]
On December 20, 2016, the Digital Currency Alliance - China FinTech Digital Currency Alliance and FinTech Research Institute were officially established, with Huobi being one of the co-initiators. [5]
Some areas where blockchain can be used are:
▪ Smart contracts
▪ Securities trading
▪ E-commerce
▪ Internet of Things
▪ Social communication
▪ File storage
▪ Proof of existence
▪ Identity verification
▪ Equity crowdfunding
We can compare the development of blockchain to the development of the Internet itself In the future, something called finance-internet will be formed on the Internet, and this thing is based on blockchain, and its precursor is bitcoin, that is, traditional finance starts from private chains and industry chains (local area networks), biStarting from the public chain (wide area network), the tcoin series all express the same concept - digital assets (Digital Asset), and finally converge to an intermediate balance point.
The evolution of blockchain is:
▪ Blockchain 1.0 - digital currency
▪ Blockchain 2.0 - digital assets and smart contracts
▪ Blockchain 3.0 ——The implementation of distributed applications in various industries
Blockchain is divided into three categories, which is introduced in detail in the book "Blockchain: Defining the New Pattern of Future Finance and Economics" [2] issued by Currency, < br />Hybrid blockchains and private blockchains can be considered as broad private chains:
Public Blockchains (PublicBlockChains)
Public blockchains refer to: any individual or group in the world Transactions can be sent and effectively confirmed by the blockchain, and anyone can participate in its consensus process. The public blockchain is the earliest blockchain and the most widely used blockchain. The virtual digital currencies of all major bitcoins series are based on the public blockchain. There is only one blockchain corresponding to this currency in the world. .
Consortium (Industry) Blockchain (ConsortiumBlockChains)
Industry Blockchain: Multiple preselected nodes are designated within a certain group as bookkeepers, and the generation of each block is jointly performed by all preselected nodes. Decision (pre-selected nodes to participate in the consensus process), other access nodes can participate in transactions, but do not participate in the accounting process (essentially still managed accounting, just become distributed accounting, how many pre-selected nodes, how to determine the number of each block The bookkeeper becomes the main risk point of the blockchain), and anyone else can conduct limited queries through the open API of the blockchain.
Private Blockchain (privateBlockChains)
Private Blockchain: Only uses the general ledger technology of the blockchain for accounting. It can be a company or an individual, and has exclusive access to the writing of the blockchain. With access permissions, this chain is not much different from other distributed storage solutions. (Dec2015) Conservative giants (traditional finance) all want to experiment with private blockchains, while public chain applications such as Bitcoin have been industrialized, and private chain application products are still being explored.

② What does blockchain mean?

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the basis for Bitcoin. underlying technology. The blockchain is a series of data blocks generated using cryptographic methods. Each data block contains the information of a Bitcoin network transaction and is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
The blockchain is public on the Internet and can be queried in every offline Bitcoin wallet data. Bitcoin wallet functionality relies on blockchainConfirmation, an effective inspection is called a confirmation. Usually a transaction requires several confirmations before it can proceed. Lightweight Bitcoin wallets use online confirmations, which means they do not download blockchain data to device storage.
Bitcoin’s many altcoins also use the same design, with slightly different proof-of-work and algorithms. Such as: Proof of Stake, SCrypt, etc.

③ What exactly is the blockchain?

The blockchain is a special network ledger. The core of blockchain technology is digital encryption. As early as 1991, a group of young people invented a new encryption technology that mutually verifies each other in order to prevent the date of electronic documents from being tampered with. They use cryptography to concatenate and protect concatenated text records (also known as blocks) of content.

The unit in which blockchain stores data is a block, and each block is strictly queued in order to form a "chain". If someone wants to change the content of a certain block, the unique characteristics of the block will also change accordingly, and subsequent blocks will immediately reject it, and this "fake" block will have to be detached from the chain.

(3) What is the blockchain network? Extended reading

Users from all over the world can connect their servers to In the blockchain network, it becomes an independent node in this distributed database storage system. Once joined, the node has the same rights and obligations as all other nodes.

Thus, people who provide services on the blockchain can perform read and write operations on any node in the system. All nodes around the world will complete synchronization again and again according to a certain mechanism, so that the data of all nodes in the blockchain network is completely consistent.

It is precisely because of the two characteristics of immutability and decentralization. Blockchain has well solved the trust problem that is a headache in modern business society. It has already emerged in social fields such as financial services, Internet of Things, public services, social welfare and supply chain management.

④ What is blockchain

On May 27, 2021, the Ministry of Industry and Information Technology and the Office of the Central Cybersecurity and Information Technology Commission issued the "About Accelerating the Promotion of Blockchain" "Guiding Opinions on Technology Application and Industrial Development" (Ministry of Industry and Information Technology Lianxinfa [2021] No. 62), the document defines blockchain as follows:
Blockchain is an important part of the new generation of information technology and is a distributed New database software that integrates various technologies such as network, encryption technology, smart contracts, etc., is expected to solve the trust and security issues in cyberspace through data transparency, difficulty in tampering, and traceability, promote the transformation of the Internet from transmitting information to transmitting value, and reconstruct information industrial system.
Blockchain is the cornerstone of building trust and a trusted network that enables credit transfer and value transfer. Reliable blockchain infrastructure allows enterprises and governments to quickly and efficiently build blockchain networks and industry applications, achieve reliable and rapid flow of capital, logistics, and information flows, and achieve efficient and credible collaboration, helping to reduce collaboration costs and improve Efficiency
ObjectThe application of blockchain + industry mainly has the following directions:
Blockchain + insurance industry, insurance companies can optimize business processes and reduce risks through the needs of blockchain, which is beneficial to customers who purchase insurance. Fully objective and comprehensive understanding of data;
Blockchain + supply chain enables real-time updating and sharing of information in each link of the supply chain, making it easier for personnel in each link to understand the latest information and make correct and objective business judgments.
Blockchain + medical industry, blockchain information cannot be tampered with, ensuring the accuracy and uniqueness of medical data; establishing patient electronic health records, recording real patient health data, and obtaining authorization to view through private keys, that is, protection The collection of sensitive personal data also facilitates doctors to make more accurate treatment plans.

Characteristics of the blockchain:

1. Deposit certificate< /p>

The "non-tamperable" feature of blockchain provides a solution to the problem of "certificate storage" in economic and social development. As long as the authenticity of the on-chain information and data can be ensured, the blockchain can solve the problem of "storage" and "certification" of information.

For example, in the field of copyright, blockchain can be used to store electronic evidence, which can ensure that it is not tampered with, and can link original platforms, copyright bureaus, judicial agencies and other parties through distributed ledgers, which can greatly Improve the efficiency of handling infringements.

2. Sharing

The "distributed" characteristics of the blockchain can break through the "data barriers" between departments and achieve information and data sharing. Different from centralized data storage, the information on the blockchain will be distributed to each node through point-to-point broadcasting, and all information can be "truthfully recorded" through "whole network witness".

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm. Blockchain (Blockchain) is an important concept of Bitcoin. It is essentially a decentralized database.

At the same time, as the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains a batch of bits. The information of currency network transactions is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

In fact, the original English version of the Bitcoin white paper does not appear in the word blockchain, but uses the chain of blocks. In the earliest Chinese translation of the Bitcoin white paper, chain of blocks was translated into blockchain. This is the earliest time the Chinese word "blockchain" appeared.

Applications of blockchain:

area Blockchain has potential huge application value in financial fields such as international exchange, letters of credit, equity registration and stock exchanges. Applying blockchain technology to the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection. This can greatly reduce costs while quickly completing transaction payments.

For example, Visa launched Visa B2B Connect based on blockchain technology, which can provide institutions with a lower-cost, faster and safer cross-border payment method. Visa uses cross-border payment methods to process business-to-business transactions worldwide.

Be aware that traditional cross-border payments require waiting 3-5 days and paying 1-3% transaction fees. VisaIt also launched the first Bitcoin debit card in conjunction with Coinbase, and Citibank is testing running the cryptocurrency "Citicoin" on the blockchain.
