Abstract

The invention discloses an accounting method and device, applied to a block chain system, the block chain system comprises at least two nodes, and the method comprises the following steps: a first node receives a first transaction request sent by a transaction initiator; wherein the first node is any node in the block chain system; the first node obtains first state data at the current moment froman account book of the block chain system according to the first transaction request; wherein the first state data is used for representing the current state of an account corresponding to the firsttransaction; the first node executes the first transaction request according to the first transaction request and the first state data and generates a first transaction value; wherein the first transaction value is a result after the first transaction request is executed; and packaging the first state data and the second transaction value into a first message, and issuing the first message to theblock chain system.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to an accounting method and device. Background technique [0002] In order to improve business processing capabilities, different node servers in the blockchain may process multiple transactions at the same time. To avoid concurrency conflicts, a multi-version control protocol (MVCC) can be used. Specifically, MVCC maintains a Version number (version), where the version number is an increasing sequence. When a node server receives a transaction, it will attach a version dependency (verDep) to each transaction, that is, set the version number of its state data for the transaction from the time it is issued to the end of the transaction. When the transaction is finally executed, it will be verified whether the additional version depends on the version of the state data of the current blockchain. If not, the transaction will be rejected. [0003] When a concurrency conflict occu...
