Embodiment

[0043] figure 1 It is a flow chart of a multi-signature implementation method provided by the embodiment of the present invention. The method can be executed by the multi-signature implementation device provided by the embodiment of the present invention, and the device can be implemented in the form of software and / or hardware. refer to figure 1 , the method may specifically include the following steps:

[0044] S101. Generate a key pair for participating in a transaction.

[0045] Specifically, it is assumed that three pairs of key pairs can be generated, which can be realized through the bigbang makekeypair command. In a specific example, the implementation is as follows.

[0046] privkey1="f1547396c4ec9f50a646b6ac791ee11fe493adc04940289752c2dc0494e040f5"

Abstract

The invention relates to a multi-signature implementation method and device, equipment, and a storage medium. The method comprises the steps of generating a key pair participating in a transaction; creating a multi-label template, and returning the address of the multi-label template; transferring a pass certificate to the multi-signature module; creating a transaction according to the multi-signature template, and returning to-be-signed data; signing the to-be-signed data, and returning signed signature data and a Boolean value; and if the Boolean value does not meet the weight condition, taking the signed signature data as a new signature object, and continuing to sign by using other private keys corresponding to a public key participating in multi-signature template establishment so asto continue to judge until the Boolean value meets the weight condition, thereby realizing multi-signature. The multi-signature scheme has the characteristics of simplicity and safety in operation andhigh running speed.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a multi-signature implementation method, device, equipment and storage medium. Background technique [0002] In real life, it is usually encountered that a document needs to be signed or stamped by several units or departments to be valid. Multi-signature technology is a way to solve this kind of problem in the network environment. As early as December 2011, multi-signature technology was implemented in the core code of Bitcoin. In January 2012, the first transaction using multi-signature technology appeared on the blockchain. With the passage of time, multi-signature technology has become more and more mature, and its application scenarios are also increasing. For example, in decentralized e-commerce, using the multi-signature method, the buyer transfers the token to the multi-signature address, and the seller can transfer the token in the address only if both par...
