Abstract: An asynchronous accounting method for a blockchain is provided. After a block reaches a consensus, different types of data contained in block information of the block are written into message queues corresponding to the respective types of data. Each of the message queues correspond to a different one of the types of data contained in the block information. A next round of block consensus processing is started after the different types of data are written into the message queues corresponding to the respective types of data. The different types of data are read from the message queues corresponding to the respective types of data to perform persistence processing of a blockchain ledger.
