Multi-signature based digital currency wallet service management method and system

Abstract

The invention discloses a multi-signature based digital currency wallet service management method and system. The system includes a contract verification server and three wallet service party terminals, each of the three wallet service party terminals holding a set of secret keys. The method includes that a wallet client terminal initiates a service request and sends the request to a wallet service provider terminal; the wallet service provider terminal and a wallet client terminal or a wallet service supervisor terminal selected according to the type of the service request perform digital signing on the service request data according to private keys held by themselves and the service request data with multiple signatures is obtained; the wallet service provider terminal sends the servicerequest data with the multiple signatures to the contract verification server; the contract verification server verifies the service request data with the multiple signatures according to a service-related contract and corresponding service processing is performed after the verification. According to the invention, the service traceability is high and the safety and reliability of digital currencyare high.

Description

technical field [0001] The invention relates to the technical field of digital currency, in particular to a multi-signature-based digital currency wallet business management method and system thereof. Background technique [0002] Existing digital currencies such as BTC, ETH, and XRP currently have two commonly used management methods. One is that the user creates a digital currency wallet locally and transfers the digital currency to the wallet at the same time to ensure the user's absolute ownership; the other is The user entrusts the digital currency to the trading platform, and the trading platform manages it on its behalf. [0003] However, there are potential safety hazards in the above two methods. In the first way, the user needs to keep the key by himself. Once the key is lost or leaked, the user cannot log in to the wallet client to retrieve the lost private key, resulting in property loss; in the second way, once the exchange is attacked or appears When guarding...

AI Technical Summary

Problems solved by technology

[0003] In the above two methods, there are security risks

In the first way, the user needs to keep the key by himself. Once the key is lost or leaked, the user cannot log in to the wallet client to retrieve the lost private key, resulting in property loss; in the second way, once the exchange is attacked or appears When guarding against self-theft, since the private key is stored in the exchange, it is easy to cause the loss of the private key, which poses a security risk, and the lost private key cannot be retrieved

It can be seen that in the above two methods, it is very difficult to retrieve the private key after it is lost.

[0004] Moreover, in the above two methods, the private key is only held by the user or the exchange. When it is necessary to query business records, once the user or the exchange has a business error or other problems that make it impossible to query, it is difficult to record the transaction. Traceability makes the security and reliability of digital currency storage low
