Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
A blockchain is a decentralized database that contains a list of what are called blocks, with records that are growing and aligned. Each tile contains a timestamp and a link to the previous tile: the blockchain is designed so that the data is not tampered, and once recorded, the data in a block is not reversible. The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. The consensus mechanism is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes in the blockchain system. The Blockchain (Blockchain) is an important concept of the bit coins, and the firecoin network is combined with an internet financial laboratory of the five-crossing financial institute of Qinghua university and a global bit coin development research report 2014-2016 issued by Xinghao science and technology to mention that the Blockchain is a bottom layer technology and a basic framework of the bit coins, is essentially a decentralized database and is used as the bottom layer technology of the bit coins. The block chain is a series of data blocks which are associated by using a cryptographic method, and each data block contains information of one bitcoin network transaction, so that the validity (anti-counterfeiting) of the information is verified and the next block is generated. In a narrow sense, the blockchain is a distributed account book which is a chain data structure formed by combining data blocks in a sequential connection mode according to a time sequence and is guaranteed in a cryptographic mode and cannot be tampered and forged. Broadly, the blockchain technique is a completely new distributed infrastructure and computing that utilizes blockchain data structures to verify and store data, distributed node consensus algorithms to generate and update data, cryptographic means to secure data transmission and access, and intelligent contracts composed of automated script code to program and manipulate data. Blockchain design is a protective measure, such as (applied to) highly fault-tolerant distributed computing systems. The blockchain enables mixed consistency, and is suitable for recording events, titles, medical records and other activities requiring data inclusion, identification management, transaction flow management and provenance management. The blockchain has huge potential for financial off-media and has huge influence on leading global trade. The concept of blockchains was first proposed by the mingent in 2008, and in the following years, bitcoins became the core component of electronic money: as a common ledger for all transactions, the blockchain database can be managed autonomously by using a peer-to-peer network and a distributed timestamp server, and the blockchain invented for bitcoin makes bitcoin the first digital currency to solve the problem of repeated consumption, and the design of bitcoin has become an inspiration source for other applications.
