Today, asymmetric encryption can solve this signature problem. The encryption and decryption of asymmetric encryption algorithms use two different keys. These two keys are the public and private keys that we often hear. Public and private keys generally appear in pairs.
In fact, we must find out that the most important thing about hoarding money is the security of the private key, the security of the private key, the security of the private key (three times).

Private keys generated from physical hardware are more secure, and eNotes products' private keys cannot leave the encryption chip throughout their lifecycle, meaning that the private key cannot be exported and imported.

The log-out operation simply clears the app's local state, causing web browsers and clients to forget to apply specific private keys.
Layered determinism wallets, all of which are derived from a primary private key according to certain rules, but are split into many child private keys, which are split into grandchildren's private keys, and so on, resulting in an infinite number of private keys. This way, even if one child private key is compromised, it will not affect the security of other child private keys.
