Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing:

[0013] As shown in the figure, this kind of blockchain system that supports the national secret algorithm, the blockchain is composed of several increasing blocks such as block 1, block 2, block 3, and block N. Each block is associated with the summary information, and each block header contains the summary information of the previous block, ensuring that all the blocks linked together can be arranged in order through the summary information, and the new block is in the specified A block is generated every N minutes and appended to the end of the block chain. Each block contains transaction information within N minutes, and the transaction information capacity is a specified size. The blockchain of the present invention generates a block approximately every 2 minutes. The new block is appended to the previous block to form a chain structure, and each block contains transac...

Abstract

The invention relates to a block chain system supporting a national algorithm. A block chain consists of a block 1, a block 2, a block 3,..., and a block N (N is increased gradually), wherein all the blocks in the block chain are correlated with each other through abstract information. The head of each block comprises the abstract information of the former block, thereby guaranteeing that all connected blocks can be arranged in order according to the abstract information. A new block generates one block in each N specified minutes, and the block is attached to the tail of the block chain. The beneficial effects of the invention are that the system combines the national algorithm SM2 and the block chain, guarantees that the block chain technology can select the national algorithms SM2 and SM3 to carry out asymmetric encryption and decryption and abstract operation in the data recording processing on the basis of achieving the de-neutralization and openness and transparency, achieving the existing distributed account book technology and enabling each person to participate in the recording of a database, and is enabled to meet the national standard and the monitoring requirements.

Description

technical field [0001] The present invention relates to the field of Internet technology, in particular to technologies such as block chain and national secret algorithm, especially a block chain system supporting national secret algorithm. Background technique [0002] Blockchain is a data structure that organizes and maintains large amounts of data in a decentralized manner based on cryptography. All data on the blockchain is accompanied by the digital signature of the relevant user and cannot be forged. Blockchain version number, timestamp, last block summary, random number, transaction root node, transaction information. The blockchain can be imagined as a ledger, and each block is a page of accounts in the ledger. Each ledger page contains all transactions for a preset time period. The existing blockchain technology completely uses the ECDSA algorithm, which cannot meet the domestic regulatory requirements. At the same time, it does not support the selection of algor...
