Abstract
Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for blockchain transaction processing. One of the methods includes: obtaining, by a blockchain node, a current blockchain transaction generated based on performing a service; obtaining, by the blockchain node based on executing a smart contract, a transaction identifier of a previous blockchain transaction; recording, by the blockchain node, the transaction identifier into a transaction log so that a previous blockchain transaction is identifiable from the transaction log based on the transaction identifier, wherein the transaction log stores blockchain transactions of the current block; and recording the blockchain transaction of the current block and the transaction log into the blockchain.
