1.2 "Private key", a randomly generated string, is the only proof that the user has the ownership of digital assets.

1.3 "Public key" is generated by one-way derivation of the private key with the help of cryptographic principles, and used to generate the blockchain digital wallet address. The digital wallet address is the public receiving address.
