A kind of block catenary system supporting the close algorithm of state

The present invention relates to a kind of block catenary system supporting the close algorithm of state, block chain is by block 1, block 2, block 3, several ever-increasing blocks such as block N are constituted, it is associated by summary info between each block in block chain, each block head includes the summary info of a block, ensureing that all blocks linked together can be arranged in order by summary info, new block produces one piece within every N minute specified, and is attached to block chain end.The invention have the advantages that: the present invention is close for state algorithm SM2 and block chain combination, ensure that block chain technology is realizing existing distributed account book technology, neutralization, open and clear is removed in realization, on the basis of allowing everyone each may participate in data-base recording, during data record, can select to use state close algorithm SM2, SM3 to carry out asymmetric encryption and decryption computing, summary computing respectively so that it is meet domestic standard and regulatory requirements simultaneously.
