Abstract: The present invention provides a transaction method and a node design in a blockchain system. A client initiates a transaction by using an SQL write command including transaction data or queries transaction data by 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 used to write the block data, thereby writing the block data to an RDB database. In embodiments of the present invention, an RDB data block is connected to the blockchain system, so that data query and processing capabilities of the blockchain system are improved.
