Abstract

The invention discloses a design method and a device for realizing a block chain system supporting multiple signatures. The design method comprises: receiving a first transaction, wherein the first transaction is used for deploying an intelligent contract, the first transaction at least comprises a to-be-deployed intelligent contract, a first multi-signature rule associated with the intelligent contract and a first transaction identifier, and the first multi-signature rule comprises a set first public key set, a first signature threshold value and first consensus information comprising a firstconsensus rule; deploying an intelligent contract and generating a contract address of the intelligent contract; storing a first transaction voucher, wherein the first transaction voucher comprises acontract address, a first multi-signature rule and a first transaction identifier; And returning the contract address of the smart contract. The disclosed method and device reduce the code burden ofthe smart contract to reduce the scale and complexity of a local account book, support the change of multiple signature rules on the basis of not modifying the original smart contract data, and reducethe resource consumption caused by the redeployment of the smart contract.

Description

technical field

[0001] The disclosure belongs to the technical field of blockchain, and in particular relates to a design method for implementing a blockchain system supporting multiple signatures and a design device for implementing a blockchain system supporting multiple signatures. Background technique

[0002] Blockchain (Blockchain) is a distributed database system that can safely store data. It is characterized by using cryptography to protect information from malicious forgery or tampering while recording all transaction information, thereby ensuring the authenticity of data. . Due to the decentralization and non-tampering characteristics of blockchain, this technology is widely used in scenarios such as digital assets, decentralized exchanges, financial derivatives, e-commerce, smart assets, and anti-counterfeiting traceability.

[0003] Smart contracts refer to decentralized protocols that implement business function requirements on the blockchain. First use high-...
