In what order does the blockchain trade
blockchain is a new application mode 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 data blocks generated by using cryptographic methods. Each data block contains the information of a bitcoin network transaction, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
some areas where blockchain can be used can be as follows:
& ᦇ 9642; Smart contract; Securities trading; E-commerce; Internet of things; Social communication; File storage; Proof of existence; Authentication
&9642; Equity crowdfunding
we can compare the development of blockchain with the development of the Internet itself. In the future, something called finance Internet will be formed on the Internet. This thing is based on blockchain, and its precursor is bitcoin, that is, traditional finance starts from private chain and instry chain (LAN), bitcoin series starts from public chain (WAN), They all express the same concept - digital asset, and finally converge to an intermediate equilibrium point
The evolution mode ofblockchain is as follows:
& 9642; Blockchain 1.0 digital currency; Blockchain 2.0 digital assets and smart contracts; Blockchain 3.0: implementation of distributed applications in various instries
first, define the
blockchain as an open network ledger. It originated from bitcoin and is the underlying technology of bitcoin. In bitcoin transactions, all the information of transaction records will be packaged into a "block" for storage. With the expansion of information exchange, one block links with another, forming a blockchain
Second, the digital currency represented by bitcoin is a point-to-point e-cash system. Among them, every transaction will broadcast to all participants in the network, and it will be recorded in the account book after repeated confirmation, which is called "blockchain". Each participant will have his own account book. In this way, when false information occurs, it can be broken through mutual verification, so as to ensure network securityin the blockchain, every node is equal, and there is no centralized management organization. This "decentralized" feature makes the blockchain do not need to rely on a third party, its operation does not need any human intervention, and it can independently conct self verification. In addition, the network of blockchain is open to the world, and anyone can query data through the public port, so the whole system is highly transparent
In a word, blockchain is a reliable database and a reliable "account book". In the future, it will be applied in cross-border payment, securities, loans, voting, etc. For example, in cross-border payment, with the security of blockchain, you can remit money to the world anytime and anywhere, which saves a lot of intermediate links and high feesin a narrow sense, blockchain is a kind of chained data structure, which is composed of data blocks connected in sequence according to the time sequence, and is a distributed account that can not be tampered with and forged by cryptography. In a broad sense, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
blockchain and big blockchain are not the same concept. Big blockchain should be the name of a company. Bitcoin, Ethereum and decent are all successful cases of blockchain technology.
What is blockchain? What kind of changes will it bring to the future life
blockchain is a new application mode 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 data blocks generated by using cryptographic methods. Each data block contains the information of a batch of bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
in fact, the word blockchain does not appear in the original English version of bitcoin white paper, but the word chain of blocks. In the earliest Chinese translation of bitcoin white paper, chain of blocks was translated into blockchain. This is & lt; Blockchain & quot; This Chinese word first appeared
on January 10, 2019, the state Internet Information Office issued the regulations on the management of blockchain information services, which will come into effect on February 15, 2019
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it can not be tampered with and forged by cryptography
In the end, this is undoubtedly a new life changing technology. In the future, the proction activities of the whole society will be carried out with blockchain as the underlying logic. Many things are within our reach. With the integration of artificial intelligence and big data, we can easily handle the seemingly complicated things, For example, some securities market transactions and intelligent matching of financial activitiesit's easy to understand that blockchain is the integration of people, property, man, machine, material, man, field and goods, which is packaged into a whole; A network computing center that runs on an infrastructure
