Two-month later theories step into practice, and a first creation block with the serial number of 0 is born on 1 month and 3 days in 2009. The block with the number 1 appears in 2009 at 1/9, and is connected with the created block with the number 0 to form a chain, which marks the birth of the block chain.
In recent years, the attitude of bitcoin in the world has fallen, but a blockchain technique, which is one of bitcoin underlying techniques, has been increasingly emphasized. In the process of forming the bitcoin, the blocks are storage units one by one, and all communication information of each block node within a certain time is recorded. The blocks are linked through random hashing (also called hashing algorithm), the next block contains the hash value of the previous block, one block is connected with one block successively along with the expansion of information exchange, and the formed result is called a block chain.
