Problems solved by technology

The design idea of ​​the oracle machine currently has a centralized implementation method and a decentralized implementation method completely based on the blockchain. The centralized method is stable and efficient, but it is difficult to gain the trust of blockchain users; the decentralized implementation method, It is very complicated to implement not only the convenience of use, but also the perfect reward and punishment mechanism for data providers to ensure accurate data and stable system operation.
Many contracts on the blockchain rely on data outside the chain, and the existing blockchain technology cannot satisfy the need to truly and accurately input data outside the chain into the chain

Abstract

The invention provides a data publishing method, a data calling method, data calling equipment and a storage medium. The method comprises the steps: receiving and executing a first transaction which is sent by a first data publishing terminal and publishes a first event which does not generate a result, and recording the first event on a block chain; Receiving and executing a plurality of second transactions of the to-be-audited results of the first event sent by the plurality of data release terminals, recording the plurality of to-be-audited results on the blockchain for the audit terminal to obtain and audit, and generating a third transaction of the result of releasing the first event when the audit is passed; Receiving and executing a third transaction, and recording a result of the first event on the block chain. The data outside the chain can be truly and accurately input into the chain.

Description

technical field [0001] The present application relates to the technical field of block chain, and specifically relates to a data release method, a data calling method, a device and a storage medium. Background technique [0002] There is a gap between the blockchain and the data in the real world. The oracle is used to input the data outside the chain into the chain accurately and accurately, so as to ensure the authenticity of the data on the chain and realize the credible communication between the smart contract and the outside world. to interact. The design idea of ​​the oracle machine currently has a centralized implementation method and a decentralized implementation method completely based on the blockchain. The centralized method is stable and efficient, but it is difficult to gain the trust of blockchain users; the decentralized implementation method, It is very complicated to implement not only the convenience of use, but also the perfect reward and punishment mech...
