What does blockchain mean (what is blockchain? How to play with blockchain)

        Blockchain is a serial transaction record (also known as block) connected and protected by cryptography. It is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism and encryption algorithm. As an important concept of bitcoin, blockchain 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 cryptography methods. Each data block contains information of a batch of bitcoin network transactions, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block. Blockchain is an important concept of bitcoin. The 2014 & mdash; 2016 global bitcoin Development Research Report released by Huobi in conjunction with the Internet Finance Laboratory of Wudaokou School of finance, Tsinghua University and Sina Technology mentions that blockchain is the underlying technology and infrastructure of bitcoin.
 
        In essence, it is a decentralized database and serves as the underlying technology of bitcoin. The blockchain is a series of data blocks generated by using cryptography methods. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block. In a narrow sense, the blockchain is a chain type data structure that combines data blocks in a chronological order in a sequential manner, and a distributed ledger that can not be tampered with and forged by means of cryptography. Broadly speaking, blockchain technology is a brand-new distributed infrastructure and computing paradigm that uses block chain 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 smart contracts composed of automated script code to program and operate data.
