Understanding Cryptocurrency Wallets
Cryptocurrency wallets are essential tools for managing digital assets securely. Unlike physical wallets, they don't store currency but rather provide access to blockchain records through cryptographic keys.
Key Components:
- Public Key: A shareable address for receiving funds (e.g.,
0x71C7656EC7ab88b098defB751B7401B5f6d8976F) - Private Key: A secret password to authorize transactions (e.g.,
