PublicKey

2. Cryptography
• Public and Private Keys:
- Public Key: Acts as an address others use to send you crypto (like an email address).
- Private Key: A secret code to access and authorize transactions (like a password). Losing it means losing access to your funds.
- Security: Transactions are encrypted, ensuring only the intended recipient can decrypt them using their private key.

💰 What Is a Public Key?

A public key is like your crypto email address—it’s the unique code you share with others so they can send you $BTC , $ETH , $XRP , or any. Unlike your private key, this one is meant to be public.
It lets people send funds to your wallet but doesn’t give them access to your crypto.

✨ Why It Matters

• Receive Crypto: Share your public key to get coins from friends, exchanges, or payments.

• Safe Sharing: Since it only allows incoming transfers, it’s safe to share publicly.

• Foundation of Blockchain: Public keys work with private keys to secure and verify transactions.

💡 Real-World Analogy

Think of your public key like your email address—you give it to people so they can send messages (or crypto!). But they can’t open your inbox or read your emails without the password (private key).

🚀 Pro Tip
Always double-check the public key or wallet address before sharing or initiating transactions. A small error can lead to funds being sent to the wrong address, and such transactions are typically irreversible in the blockchain world.
