Understanding Keys and Wallets
This module explains how users interact with blockchains through cryptographic key pairs and wallet software.
Public/Private Keys
情報
For a more detailed guide on this topic, see Private Keys and Public Keys.
Every user interacts with a blockchain through a cryptographic key pair:
- Private Key: A secret number used to sign transactions.
- Public Key: Derived from the private key.
- Address: A shortened, user-friendly representation of the public key.
Transactions are "signed" using the private key, proving ownership without revealing the key itself.
