All transactions in the cryptocurrency represented by bitcoin are stored in a public database called blockchain. With the widespread use of cryptocurrency, the security issues of currency loss and theft have become more and more prominent. Cryptocurrency is often used through wallets for convenience and security reasons. The most important data stored in the wallet is the user’s private key, which is the unique identifier of the ownership of encrypted digital currency. Once lost or stolen, there will be irreparable losses. According to the storage and use mode of private key, the wallet is divided into four types:hardware wallet, software wallet, managed wallet and threshold wallet, and several popular wallet schemes are introduced. Through the analysis and comparison of the convenience, security and efficiency of various wallet schemes, the advantages and disadvantages of various wallet schemes are summarized, and the development trend of future wallet schemes is proposed.
