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 the invention provides a private key recovery method and device, a collaborative address creating method and device, a collaborative address signing method and device and a storage medium. The collaborative address signing method comprises the following steps: receiving a transaction request initiated by a first client for a target cooperative address, wherein the transaction request comprises a transaction hash value and a signature generated by the first client by using a private key fragment of the first client; verifying the signature by using a first public key corresponding to the private key fragment; and when the signature passes the verification, based on private key fragments held by the user, cooperating with a server to carry out threshold signature based on secure multi-party calculation on the transaction request so as to generate a transaction signature. According to the embodiment of the invention, the security and convenience of the password currency wallet can be improved.

Description

technical field [0001] This specification relates to the technical field of cryptocurrency wallets, and in particular to a private key recovery, creation of collaborative addresses, signature method and device, and a storage medium. Background technique [0002] The ownership of cryptocurrency depends entirely on whether the corresponding private key is held, so the security of 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 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...
