Abstract

The invention provides a database write-in method and system based on a block chain network. The method comprises the following steps: receiving transaction information comprising database operation; establishing database transaction according to the database operation, and storing the database transaction in a local database; sending the transaction information into a current block chain network to participate in consensus; receiving returned consensus result information and judging whether the transaction information passes through the consensus or not; if yes, submitting the database transaction in the local database; and if not, retreating the database transaction in the local database. The database operation is stored in the database before the consensus is performed in a database transaction manner, that the database transaction is submitted or retreated is judged according to the consensus result after the consensus is completed, so that read-write consistency of the database is guaranteed in the consensus process.

Description

technical field [0001] This application relates to the technical field of block chain, in particular to a database writing method and system based on block chain network. Background technique [0002] For database operations through transactions in the blockchain network, the transaction information needs to participate in the consensus of the blockchain network. After each node votes to determine whether the transaction is passed, the voting process takes a certain amount of time. For example, every transaction on the Ripple network After submitting, it takes 3-8 seconds for the whole network to vote. During the period before the consensus is passed, it will lead to the problem of inconsistency in reading and writing. Contents of the invention [0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a database writing method and system based on a blockchain network that ensures consistent reading and writing of the databa...
