Abstract

The invention discloses an accounting method and device, which are applied to a block chain system. The block chain system includes at least two nodes. The method includes: the first node receives a first transaction request sent by a transaction initiator; The first node is any node in the blockchain system; the first node obtains the first state data at the current moment from the ledger of the blockchain system according to the first transaction request; The first status data is used to characterize the current status of the account corresponding to the first transaction; the first node executes the first transaction request according to the first transaction request and the first status data, and Generate a first transaction value; the first transaction value is the result of executing the first transaction request; package the first state data and the second transaction value into a first message, and publish it to the block 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...
