Abstract: Embodiments of the present disclosure relate to methods, devices, a computer readable storage medium and a computer program product for processing or managing a blockchain transaction. In a method for processing a blockchain transaction, a blockchain node of a blockchain for processing the blockchain transaction receives a transaction request, the transaction request indicating at least a initiator of the transaction, transaction content and a transaction recipient of the transaction. The blockchain node computes, based on the transaction content, a transaction fee for processing the transaction. The blockchain node determines whether the initiator of the transaction is a sponsored user of the transaction recipient, and determines a payment account from which the transaction fee is deducted in response to determining that the initiator of the transaction is a sponsored user of the transaction recipient.

Abstract: Embodiments of the present disclosure relate to a method, a device, a computer readable storage medium and a computer program product for transaction processing on a blockchain. In the method, the blockchain node for processing a transaction receives a transaction request including a plurality of fields, the plurality of fields including a transaction task field including a plurality of clauses and each clause of the plurality of clauses indicating one of a plurality of tasks of the transaction. The blockchain node processes the plurality of tasks and determines that the transaction is successfully processed only in response to successfully processing all the plurality of tasks. The transaction processing as provided in the present disclosure enables multiple tasks to be processed through a single transaction procedure on the blockchain in an efficient way.
