Abstract

The present disclosure discloses a method and a system for accessing out-of-chain data based on a consortium block chain. The method for accessing out-of-chain data is performed by an agent program, the method for accessing out-of-chain data including: obtaining an access request to out-of-chain data sources sent by a first smart contract on the consortium block chain from a second smart contract, wherein the second smart contract is generated based on the out- of-chain data sources and is deployed on the consortium block chain; searching out-of-chain data in the out-of-chain data sources according to the access request; and sending the out-of-chain data to the second smart contract. By applying the method for accessing out-of-chain data of the present disclosure, the access of the smart contracts to a variety of out-of-chain data sources may be realized in a unified standard manner on the consortium block chain while ensuring the security of the access.
