Abstract

The invention discloses a method and a device for realizing an oracle machine calling process based on a smart contract. The method comprises the following steps: acquiring an oracle machine calling event of an original transaction, wherein the oracle machine calling event comprises an oracle machine calling request, a request identifier and an intelligent contract address of an intelligent contract of an original transaction, and the request identifier is generated based on the oracle machine calling request and is globally unique; sending an oracle machine calling event to the trusted execution environment module during original transaction block writing; starting a timer and sending a data acquisition request based on the oracle machine calling request to the outside; and if an external response to the data acquisition request is received before the timer finishes running, constructing a first callback transaction and sending the first callback transaction to the executor, thereby enabling the executor to execute the first callback transaction, and further executing callback logic of the smart contract of the original transaction. According to the embodiment of the invention, the transaction execution speed of the blockchain is ensured, the transaction execution efficiency is high, and contract code writing is simple.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method and device for realizing an oracle calling process based on a smart contract. Background technique [0002] As a sandbox execution environment, the smart contract of the blockchain can effectively execute the user's logic code and limit some behaviors that may lead to inconsistent execution results. Therefore, the function of executing the contract on the blockchain is relatively limited and very difficult. Difficulty interacting with the outside world. The oracle machine is a mechanism for writing information outside the blockchain into the blockchain. This mechanism solves the technical problem that the smart contract of the blockchain is difficult to interact with the outside world. [0003] In the prior art, the oracle machine is invoked in a synchronous waiting manner, that is, the oracle machine is called and waits for the result to be returned, and the next ...
