Problems solved by technology

Among them, the security of the exchange’s custody and online wallet is relatively low, and incidents such as theft of the exchange’s cryptocurrency and the loss of the private key of the online wallet may easily occur.
The hardware wallet stores the private key offline in the hardware device. This method prevents the private key from being exposed to the network environment and the risk of being attacked by hackers, which can improve security. However, when the user needs to transfer money , you need to insert a hardware device or manually enter the private key, which is inconvenient to use

Abstract

The embodiment of this specification provides a method and device for generating a coordinated address, a transaction signature method, and a storage medium. The method for signing a transaction with a coordinated address is applied to a client in a blockchain network, which includes: initiating a transaction signature for the coordinated address to the server For a transaction request, the coordinated address is generated by the client and the server by performing secure multi-party computation on the key fragments held by them; Request a threshold signature based on secure multi-party computation to generate a transaction signature. The embodiment of this specification can improve the security and convenience of the cryptocurrency wallet.

Description

technical field [0001] This specification relates to the technical field of cryptocurrency wallets, and in particular, to a method and device for generating a collaborative address, a transaction signature, and a storage medium. Background technique [0002] As a carrier tool in the blockchain world, how to ensure its security is one of the important issues. The ownership of the cryptocurrency depends entirely on whether the corresponding private key is held, so the security of the cryptocurrency depends on whether the corresponding private key has a complete security protection strategy. [0003] At present, for ordinary users, the use is usually directly handed over to the cryptocurrency exchange for custody, or stored in the user's personal online wallet or hardware wallet. Among them, the security of the exchange's custody and online wallet is relatively low, and events such as the theft of the exchange's cryptocurrency and the loss of the private key of the online wall...
