Abstract

A transaction method and a node design in a blockchain system, where a client initiates a transaction using a Structured Query Language (SQL) write command including transaction data or queries transaction data using an SQL query command. A node parses an SQL command, executes a simulated transaction, and checks block data based on a transaction result of the simulated transaction after obtaining the block data. After the check succeeds, the node converts the block data into an SQL write command that writes the block data, thereby writing the block data to a relational database (RDB).
