Problems solved by technology

[0007] It is difficult to implement truly private smart contract applications by encrypting and storing data and codes in unrelated parties, because data and codes can basically only be in plain text during operation, and unrelated parties can steal
Of course, regardless of cost, blockchain nodes with deep security reinforcement may be able to prevent unrelated parties from stealing data and codes to a certain extent, but this is not a common situation

Abstract

The present invention provides a smart contract implementation method and device based on full-chain consensus and local deployment. By separating the full-chain triggering and local execution of deployment transactions and business transactions, and introducing local states, it supports A smart contract that combines full-chain consensus and contract-level consensus, local deployment, local triggering, and local storage, that is, a local contract where data and code selectively exist on blockchain nodes but participate in full-chain consensus. Because most real-world scenarios are only meaningful to the relevant parties and thus only need to be deployed on the relevant parties, this local contract architecture method can greatly increase the number of smart contracts that a blockchain network can support at the same time under the premise of a full-chain consensus. Moreover, supplemented by off-chain security relay services, this local contract architecture method can realize truly secure and private smart contracts under the premise of full-chain consensus, so as to meet the privacy requirements of real-world scenarios.

Description

technical field [0001] The present invention relates to blockchain technology, in particular to the technical field of public and private smart contracts that support partial deployment on the premise of full-chain consensus on the blockchain network. Background technique [0002] In the digital age, data is the mapping of assets and real objects on the digital platform, and code (executable "data") is the realization of business logic on the digital platform. Real-world applications are mostly private applications, which require data and codes to be "visible" and "available" only to authorized parties, but not to other parties. [0003] On a blockchain network consisting of one or more distributed controlled blockchain nodes (computing devices), the distributed ledger stores application data, and each smart contract is the logic implementation of the application. The external application submits the transaction through the blockchain protocol stack, and the blockchain prot...
