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 unr...

Abstract

The invention provides an intelligent contract implementation method and device based on full-chain consensus and local deployment, and the method comprises the steps: separating full-chain triggeringfrom local execution of a deployment transaction and a business transaction, and introducing a mode of a local state; and supporting an intelligent contract which combines full-chain-level consensusand contract-level consensus and is locally deployed, locally triggered and locally stored on a blockchain network, namely, supporting a local contract in which data and codes selectively exist at blockchain nodes but participate in full-chain consensus. As most of real scenes are only significant to related parties, the local contract architecture method only needs to be deployed at the related parties, and the local contract architecture method can greatly improve the number of intelligent contracts which can be simultaneously supported by one block chain network on the premise of full-chainconsensus. Moreover, with the assistance of an out-of-chain security relay service, the local contract architecture method can realize a real secure and private smart contract on the premise of full-chain consensus so as to meet the privacy requirement of a real scene.

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...
