Understanding Keys and Wallets

This module explains how users interact with blockchains through cryptographic key pairs and wallet software.

Public/Private Keys

정보

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.

Keep Your Private Key Safe

Anyone with access to your private key can control your funds. Never share it or store it in plaintext.
