Universal encryption currency storage method supporting multiple signatures

Abstract

The invention discloses a universal encryption currency storage method supporting multiple signatures, a main public key is obtained based on a multi-signature mode, and the main public key is calculated by adopting address generation algorithms of different block chains to obtain encryption currency addresses suitable for different block chains, so that the universality problem of a multi-signature wallet is solved, and meanwhile, the encryption currency storage method supporting multiple signatures has the advantages that the encryption currency storage efficiency is improved. According to the method, the key fragments are dispersed into a plurality of pieces of hardware and are stored by a plurality of persons, the cryptocurrency assets cannot be stolen at a single point, and once any party loses the key fragments, the key fragments can be reset, so that the situation that the cryptocurrency assets are lost due to improper storage is also avoided, and the security of the cryptocurrency assets is improved. According to the generated cryptocurrency storage address, the security is effectively improved while the privacy of user assets is protected.

Description

technical field [0001] The invention belongs to the technical field of encrypted currency storage, and in particular relates to a general-purpose encrypted currency storage method supporting multiple signatures. Background technique [0002] In the cyberspace environment, cryptocurrencies based on blockchain technology carry enormous value. Due to the characteristics of cryptocurrencies such as anonymity and cross-border circulation, individual users, companies and even government agencies have lost or misused a large number of cryptocurrencies. The reasons for the above situation generally include the case investigators guarding themselves and stealing, unaccounted for criminal members transferring funds through private keys, and third-party escrow companies using the escrow funds privately, etc. The most fundamental reason is the security risks of the cryptocurrency wallet itself. [0003] In order to prevent the hidden dangers of cryptocurrency wallets, the current pract...

AI Technical Summary

Problems solved by technology

[0006] The multi-signature method of the Ownbit wallet has the following disadvantages: poor versatility, it only supports a limited number of types of cryptocurrencies, and must be individually adapted according to the blockchain where the cryptocurrencies are located; the risk of privacy leakage is high, and some cryptocurrencies require The smart contract (program) is kept, but the smart contract running on the blockchain is open and transparent, and anyone can view and record it, which will lead to the leakage of user asset information; the risk of capital security is high, once the smart contract is written and exists Vulnerabilities, it may lead to the loss of all users' encrypted currency assets

The value of cryptocurrencies is huge, but traditional storage methods generally rely on a single point of security, which is vulnerable to theft and loss, resulting in huge economic losses

In addition, the existing multi-signature schemes often use smart contracts when hosting cryptocurrency assets such as Ethereum (ETH), which is equivalent to hosting user assets in the same public program on the network. At this time, if the contract program is written There are loopholes, and the assets under custody will be at risk of loss

[0010] The second is the versatility of multi-signature wallets

In real life, there are many scenarios that require the joint authorization of multiple parties for the custody of encrypted currency assets, such as the custody of large amounts of funds for enterprises, the custody of fined and confiscated funds, and the custody of funds in public accounts. There is no universal multi-signature wallet that can support the depository of all types of cryptocurrencies

[0011] The third is the privacy of user assets

At present, when it comes to multi-party encrypted currency depository scenarios, encrypted currency assets on blockchains such as Ethereum are stored in smart contracts. The amount of funds and who deposits them are all open and transparent, resulting in users' privacy being easily leaked
