METHOD AND APPARATUS TO RECORD SERVICE DATA IN CHAIN OF BLOCKS AND METHOD FOR DETERMINING SUBCONJECT OF SERVICES

摘要

the present application discloses a method for recording transaction data in a block chain comprising: obtaining a plurality of pieces of transaction data to be recorded in a block chain; determine transaction subsets to which the transaction data belongs according to the transaction types and / or data change ranges of the transaction data, in which there is no transaction dependency relationship between the transaction data belonging to the transaction subsets many different; and execute the subsets of transactions in parallel, and record an execution result in the block chain. the present application further discloses an apparatus for recording transaction data in a block chain and a method for determining a subset of transactions. the present order can achieve the parallel execution of transaction data without a transaction dependency relationship, thereby reducing the cost required to improve the efficiency of data processing execution and improve expandability.
