❶ What is data blockchain (BlockChain)

Blockchain is a new application model of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies . 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 related data using cryptographic methods. Each data block generated contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

(1) Blockchain and network optimization extended reading

Most public blockchain chains are limited by scalability. The biggest feature of blockchain technology is decentralization, which requires all ledgers in the network to handle the accounting process. Distributed accounting has high security, low misoperation rate, and is also politically neutral and correct.

However, while blockchain technology embraces these characteristics, it sacrifices scalability, cannot meet personalized supervision, and is slightly insufficient in protecting data privacy. Moreover, as the number of ledgers increases, the interaction delay will increase exponentially, which means that the more ledgers in the blockchain network, the higher the latency will be.

❷ What is blockchain technology? What exactly is blockchain? A chain data structure composed of sequential connections, and a cryptographically guaranteed distributed ledger that cannot be tampered with or forged.

Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data transmission and access. It is a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data securely.

[Infrastructure]

Generally speaking, the blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer composition. Among them, the data layer encapsulates the underlying data blocks and related basic data and basic algorithms such as data encryption and timestamps; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms; the consensus layer mainly encapsulates network nodes Various consensus algorithms; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, and is the core of the blockchain The basis of programmable features; the application layer encapsulates various application scenarios and cases of the blockchain. In this model, the chain block structure based on timestamps, the consensus mechanism of distributed nodes, economic incentives based on consensus computing power, and flexible programmable smart contracts are the most representative innovations of blockchain technology.

Extended information:

[Blockchain core technology]

Blockchain mainly solves the trust and security issues of transactions, so it proposes four technological innovations to address this issue:

1. Distributed ledger means that transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they can all participate in supervising the legality of the transaction and can also jointly testify for it.

The uniqueness of blockchain's distributed storage is mainly reflected in two aspects: First, each node of the blockchain stores complete data according to the block chain structure. Traditional distributed storage generally stores The data is divided into multiple parts for storage according to certain rules. Second, the storage of each node in the blockchain is independent and has equal status, relying on the consensus mechanism to ensure the consistency of storage, while traditional distributed storage generally synchronizes data to other backup nodes through the central node.

No node can record ledger data independently, thus avoiding the possibility of a single bookkeeper being controlled or bribed to record false accounts. Also because there are enough accounting nodes, theoretically speaking, the accounts will not be lost unless all nodes are destroyed, thereby ensuring the security of the accounting data.

2. Asymmetric encryption and authorization technology. Transaction information stored on the blockchain is public, but account identity information is highly encrypted and can only be accessed with authorization from the data owner. , thus ensuring data security and personal privacy.

3. The consensus mechanism is how all accounting nodes reach a consensus to determine the validity of a record. This is both a means of identification and a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and strike a balance between efficiency and security.

The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". "The minority obeys the majority" does not entirely refer to the number of nodes, but can also be the computing power and the number of shares. Or other characteristic quantities that the computer can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result.

4. Smart contracts. Smart contracts are based on these trustworthy and non-tamperable data and can automatically execute some predefined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and trustworthy, it will be easy to automate claims settlement in some standardized insurance products.

In the daily business of insurance companies, although transactions are not as frequent as those in the banking and securities industries, the reliance on trusted data continues unabated. Therefore, the author believes that using blockchain technology from the perspective of data management can effectively help insurance companies improve their risk management capabilities. Specifically speaking, it is mainly divided into risk management of policyholders and risk supervision of insurance companies.

Blockchain-Network

❸ What is a blockchain mesh network and what is it

The blockchain service network is an "Internet"-like blockchain infrastructure and is the world's first blockchain technology-based , the blockchain service network that embodies the second generation of smart Internet is also the largest alliance chain in the world, providing high-level technical solutions, credible service carriers and modern social governance systems for the development of smart cities and digital economy in my country. infrastructure.
At present, the blockchain service network has completed the overall planning and top-level design, and has completed the construction of more than 40 public city nodes in 31 provinces, municipalities and autonomous regions across the country. The blockchain service network will undergo an internal test for half a year. Subsequently, China UnionPay will actively promote security and functional testing, technical architecture optimization, business operation plan formulation, basic service capacity building, and innovative applications with partners such as the National Information Center and China Mobile. promotion and other work, and finally realize the commercial operation of the entire system.

❹ What is blockchain

When everyone talks about blockchain and digital currency, they all look at it with dismay and avoid it with fear

What is blockchain?

What is digital currency?

Let the public be more intuitive and clearly understand that this is blockchain.

What is blockchain? Many people are still not very clear about blockchain. Let’s give you a simple explanation. Let’s take a look.

1. Blockchain concept

Professional terminology: Blockchain is a distributed data storage, point-to-point transmission,

consensus mechanism, encryption algorithm and other new application models of computer technology.

Popular handout: Quoting the explanation in the video, the blockchain replaces all these opaque cups with transparent cups, so that you can always know where your money is, and it will always belong to you. Will be stolen by others.

2. Blockchain

Basic characteristics

1. Decentralization

In traditional centralized network systems In a decentralized blockchain network, hackers can destroy the network by attacking a central node. However, in a decentralized blockchain network, there is no central node to attack

Moreover, the decentralized transaction method is convenient and convenient. There is no third party intervention, and point-to-point direct interaction makes large-scale information interaction a reality

It not only ensures that the information is not leaked, but also ensures that the key is in your hand, and transactions can be fast and convenient.

2. Openness

The system is open. In addition to the private information of the transaction parties being encrypted, the blockchain data is open to everyone and anyone can pass it. The public interface is used to query blockchain data and develop related applications, so the entire system information is like a transparent cup, and everyone can see the contents inside.

3. Information cannot be tampered

When a block is verified and added to the blockchain, it will be stored permanently and cannot be changed unless the system is controlled at the same time. More than 51% of the nodes, otherwise the modification of the database on a single node will be invalid, so the data stability and reliability of the blockchain are extremely high.

4. Anonymity

Since the data exchange between nodes in the blockchain follows a fixed and predictable algorithm, the blockchain network does not require trust and can be based on addresses. Non-personally identifiable data is exchanged. The anonymity of the blockchain is a double-edged sword. It not only protects the confidentiality of information and the security of transactions, but it also causes rampant illegal transactions. It has caused difficulties for law enforcement agencies and created a sense of distrust among users.

The above is a partial introduction to the basics of blockchain. I believe that as the public learns more about blockchain, this technology will be recognized and used by more people.

❺ 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 confirmed the numberDigital currencies reduce the value of traditional currency issuance, and indicate that the central bank is exploring the issuance of digital currencies. 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 , something called finance-internet will be formed on the Internet in the future, 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 network), and the bitcoin series starts from public chains (Wide Area Network), they 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.Same decision (pre-selected nodes 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 decide 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.

❻ At present, the blockchain technology ecosystem continues to be optimized, which trends cannot be ignored

Technically, the blockchain technology architecture remains stable. He Baohong, director of the Cloud Computing and Big Data Research Institute of the China Academy of Information and Communications Technology, said that the overall functional architecture of the blockchain is laying a solid foundation for technological innovation iterations.
The evolution of blockchain technology will continue to be optimized and improved at the core technology level represented by encryption algorithms, peer-to-peer networks, consensus mechanisms, smart contracts, and ledger storage. At the same time, the blockchain will be interconnected, secure, and controllable. And continue to improve performance, expand scale, etc. to facilitate continuous evolution. In the future, with the diversification of business scenarios, the technology ecosystem of blockchain will be further enriched.
