In the context of the rapid development of digital currencies, security has become a focal point for users, with data protection and recovery of wallets being particularly important. The private key is the cornerstone of digital asset security; it is equivalent to the password of an account. If a user loses or discloses their private key, they are likely to face asset loss. Therefore, understanding wallet recovery knowledge related to private keys is essential and should not be overlooked.

The basic concept of a private key

A private key refers to a code composed of a randomly generated string of numbers and characters. It is not only used to prove ownership of digital assets, but also enables users to interact with the blockchain. With a private key, users can access and manage their digital currencies at any time.

1.1 The Relationship Between Private Key and Public Key

Before understanding the private key, it is necessary to first know the relationship between the public key and the private key. The public key and private key are a pair of keys; the public key can be made public, while the private key must be kept confidential. The public key can be used by others to send digital assets to the user, while the private key is used to sign transactions and protect the user's assets.
