Abstract

The invention discloses a block chain service execution method and device based on a multi-signature smart contract. The method is applied to any block chain node. Comprising the steps of deploying a multi-signature smart contract; receiving a service execution request, generating a voting invitation corresponding to the service execution request under the condition that an initiator account of the service execution request belongs to the account with the voting right and a target service indicated by the service execution request belongs to the service supported by the multi-signature smart contract, and sending the voting invitation to the account with the voting right; receiving voting content fed back by the account with the voting right for the voting invitation, and verifying the legality of a signature in the voting content; determining whether the voting content passing the legality verification meets a preset passing condition or not; and if the passing condition is satisfied, calling an execution logic corresponding to the service indicated by the service execution request in the multi-signature smart contract, and executing the target service. By applying the scheme, the reliability of group decision service execution can be improved.

Description

technical field [0001] This specification relates to the field of blockchain technology, and in particular to a method and device for executing blockchain services based on multi-signature smart contracts. Background technique [0002] In blockchain technology, also known as distributed ledger technology, it is a technology in which several computing devices jointly participate in "bookkeeping" and jointly maintain a complete distributed database. In actual business, in order to improve the security of transfers and other businesses, longer keys and more complex encryption verification algorithms can be used to reduce the possibility of passwords being cracked and assets on the chain being stolen. [0003] However, the above-mentioned longer key and more complex encryption verification algorithm can only ensure that people outside the system break through the defense, but cannot prevent insiders who own the key from doing evil; that is to say, the existing business execution...
