Problems solved by technology

[0006] However, the oracle solution of the existing technology still allows the smart contract to passively accept data, and at the same time it is still the third party introduced, which ultimately leads to a limited application range of the smart contract, and at the same time, the credibility of the data is also limited

Abstract

The invention provides an implementation method and device for a blockchain smart contract. The method comprises the following steps that: receiving a smart contract transaction request initiated froma user; dividing a data area to which the transaction request relates into an on-chain data source and an off-chain data source; carrying out consensus processing on the on-chain data source by the consensus node of the blockchain; and through an off-chain hashrate provider, carrying out calculation processing on the off-chain data, and providing a verification proof. The method supports to access a heterogeneous data source, the on-chain data source, the off-chain data source and a hybrid data source, the consensus and the calculation of the smart contract are decoupled, extraction efficiency and handling capacity are improved, and the business capability of the smart contract is greatly enhanced.

Description

technical field [0001] The present invention relates to data processing technology, specifically a method and device for realizing a block chain smart contract. Background technique [0002] Smart contracts are one of the main features of blockchain 2.0 and 3.0 applications. However, the TPS (throughput) of the system is generally low. For example, Ethereum processes about 15 transactions per second. Compared with traditional centralized applications such as VISA or There is a big gap between Taobao's tens of thousands or even hundreds of thousands of TPS per second, which cannot meet the application requirements. The reason is that in traditional blockchains such as the Ethereum platform we are familiar with, in order to ensure decentralization and security, transaction execution and block consensus are heavily dependent on the serial processing of consensus nodes, and the entire blockchain network only has the computing performance of a single machine , the computing powe...
