Transaction method and device, equipment and storage medium

The invention relates to a transaction method and device, equipment and a storage medium, relates to the technical field of block chains, and is used for solving the problem of transaction asynchronization. The method comprises the following steps: a transaction initiator node sends transaction request information of a current transaction to a block chain, wherein the transaction request information is used for requesting to confirm whether a transaction receiver node agrees to carry out the current transaction; the transaction initiator node obtains transaction response information sent by the transaction receiver node from the block chain, and under the condition that the transaction response information indicates that the transaction receiver node agrees with the current transaction, the smart contract on the block chain is called to execute the current transaction so as to generate a first synchronous transaction event; the first synchronous transaction event is used for indicating that the transaction in
