So-called block chain technology, hereinafter referred to as BT (Blockchain technology), also known as distributed books, the Internet is a kind of database technology, its characteristic is decentralized, open and transparent, let every person can participate in the database records, the technological base of block chain technology is the earliest COINS, all parts of the world in the research, which can be widely applied to financial fields,
Block, the basic principle of the chain is not difficult to understand, basic concepts including:
1. Transaction (Transaction) : an operation, lead to a change the state of the book, such as adding a record;
2. Block (Block) : record transactions over a period of time, and status as a result, is a consensus on the current state of the book;
(Chain) : 3. Chain composed of one block according to the order series, is the logging of the change of state,
4. If the block chain as a state machine, each transaction is trying to change a state, and blocks, each consensus is that the participant is blocks all transactions in the content of lead to the result of a change in state for confirmation,
With popular words: if we assume that the database into a book, read and write the database can be regarded as a kind of charge to an account, the principle of block chain technology is in a period of time to find the best fastest charge to an account, charge to an account by this person, then this page of book information to everyone else in the whole system, which is equivalent to change all database records, to the other nodes in the entire network, so the block chain technology, also known as distributed books (distributed gotten),
