The foundation of cryptocurrency security. Learn how these cryptographic keys protect your assets and enable secure transactions.
Like your home address, you can share it with anyone. People use it to send you mail (crypto). Anyone can see your address, but they cannot access what's inside.
Like the key to your mailbox, only YOU should have it. It lets you open the box and take the mail (spend crypto). If someone else gets it, they can steal everything.

Private → Public is easy. Public → Private is impossible.
Mathematically Linked
Keys are paired. Only your private key works with your public key.
Unique Pairs
Each private key generates exactly one public key.
