Public Key
Cryptographic identifier used to receive cryptocurrencies.
Beginner-friendly explanation
A public key is like an address you can share to receive crypto. It doesn’t grant access to your funds, only allows others to send you money. Example: It’s like your bank account number: you can send it to friends so they can pay you.
Intermediate-level insight
The public key is mathematically derived from the private key. It’s often converted into a public address (shortened and encoded form). Example: An Ethereum wallet shows your public address, but it originates from your public key.
Advanced perspective
The public key is based on asymmetric cryptography. Even though it’s public, breaking the mathematical link to the private key is considered impossible with current technology. Security relies on the strength of elliptic curves (e.g., secp256k1 for Bitcoin). Example: Bitcoin uses an elliptic curve called secp256k1 to generate public keys.
