BLOCK CHAIN SMART CONTRACT-BASED TRANSACTION HASH ACQUISITION METHOD AND SYSTEM

摘要

Disclosed are a a block chain smart contract-based transaction hash acquisition method and system. In the embodiments of the present invention, in one aspect, a transaction hash acquisition instruction is defined and added to an instruction set of a block chain virtual machine, and at the same time, a transaction hash acquisition logic corresponding to the transaction hash acquisition instruction is deployed in the block chain virtual machine; and in another aspect, the defined transaction hash acquisition instruction needs to be added to an instruction set of a smart contract compiler, so that a service smart contract compiled by the smart contract compiler comprises the transaction hash acquisition instruction. Thus, if the service smart contract is deployed in the block chain network, a user may simultaneously assign and call the service smart contract to execute a service initiation transaction when constructing the service initiation transaction.
