Multi-signature transaction method and device, and storage medium

Abstract

The invention provides a multi-signature transaction method and device, and a storage medium. The method comprises the following steps: generating a first multi-signature transaction, wherein the signature information of the first multi-signature transaction comprises a multi-signature identifier, a first public key of each first account capable of managing a transaction initiator of the first multi-signature transaction, and a multi-signature judgment rule capable of successfully executing the first multi-signature transaction, by the plurality of second accounts, signing the transaction content of the first multi-signature transaction according to the held private keys to obtain first signature data, and sending the first multi-signature transaction to a blockchain network, so that the blockchain node judges whether each piece of first signature data in the signature information conforms to a multi-signature judgment rule or not, and if so, executing the first multi-signature transaction. According to the invention, the service fee for generating the multi-signature transaction is reduced, and the multi-signature scene is suitable for all asset types.

Description

Technical field[0001]This application relates to the field of blockchain technology, in particular to a multi-signature transaction method, device and storage medium.Background technique[0002]In the existing blockchain equipped with an account model, suppose that the multi-signature management address of user A includes multiple multi-signature associated accounts (assuming A, C, D), and the permissions required for transfer are: in A, C 、At least two of D agree to transfer money. Now suppose that user A wants to transfer 10 coins in A's account in a multi-signature contract to B's account in a multi-signature contract through a multi-signature account. The process of initiating multi-signature is: A generates tx1(10coin(multiaddr_A,multiaddr_B )); The blockchain node executes tx1 and updates the number of consents received by tx1 to 0; A votes on tx1, and A sends tx2 (confirm(hash(tx1))), and the blockchain node executes tx2, and the above agreed number Update to 1; C votes on tx1,...

AI Technical Summary

Problems solved by technology

[0003] In the above mechanism, for example, if there are 2 addresses among the 3 addresses to sign, at least 3 ratio transactions need to be generated and three handling fees will be spent

And the above mechanism can only transfer assets to different accounts in the multi-signature contract, and cannot be applied to other contracts
