Transaction method and apparatus, device and storage medium

A transaction method, appliable to a transaction recipient node, wherein the transaction method comprises:

• obtaining, by the transaction recipient node from a blockchain, a transaction request transmitted by a transaction initiator node, wherein the transaction request is for soliciting confirmation on whether the transaction recipient node agrees to execute a current transaction;
• transmitting, by the transaction recipient node, a transaction response to the blockchain, in response to the transaction recipient node agreeing to execute the current transaction, wherein the transaction response;
• receiving, by the transaction recipient node, a first transaction event, wherein the first transaction event is generated by the transaction initiator node in response to the transaction response through invoking a smart contract on the blockchain to execute the current transaction, and the first transaction event indicates that the transaction initiator node has invoked the smart contract to execute the current transaction;
• and
• invoking, by the transaction recipient node, the smart contract on the blockchain to execute the current transaction and generate a second transaction event, wherein the second transaction event indicates that the transaction recipient node has invoked the smart contract to execute the current transaction.

A transaction method, applicable to a blockchain transaction system, wherein the blockchain transaction system comprises a transaction initiator node and a transaction recipient node, and the transaction method comprises:

• transmitting, by the transaction initiator node, a transaction request for a current transaction to a blockchain, wherein the transaction request is for soliciting confirmation on whether a transaction recipient node agrees to execute the current transaction;
• obtaining, by the transaction recipient node, the transaction request from the blockchain;
• transmitting, by the transaction recipient node, a transaction response to the blockchain in response to the transaction recipient node agreeing to execute the current transaction;
• obtaining, by the transaction initiator node, the transaction response from the blockchain;
• invoking, by the transaction initiator node in response to the transaction response indicating that the transaction recipient node agrees to execute the current transaction, a smart contract on the blockchain to execute the current transaction and generate a first transaction event, wherein the first transaction event indicates that the transaction initiator node has invoked the smart contract to execute the current transaction;
• receiving, by the transaction recipient node, the first transaction event;
• and
• invoking, by the transaction recipient node, the smart contract on the blockchain to execute the current transaction and generate a second transaction event, wherein the second transaction event indicates that the transaction recipient node has invoked the smart contract to execute the current transaction.
