Non-custodial Wallet

Abstract

The present invention discloses a method for generating keys and signatures based on multi-party calculation, and relates to the technical field of MPC the algorithm steps. The method for generating the keys and the signatures based on the multi-party calculation includes: generating public keys and sending a request for generating the public keys to the background of Party 0; performing collaborative calculation by Party 0 and Party 1 to obtain public keys through communication; and returning calculation results to a client by Party 0. By the multi-party calculation method, a wallet owner can sign by the keys, and whether a message is signed by the wallet owner through the public keys of a wallet can be verified through the public keys of the wallet. In the process, it is unnecessary to share sensitive information with other parties, and the problem that the keys are easy to lose is solved, thereby preventing properties in the wallet from being lost, and helping more non-technical users to use a blockchain wallet.
