Public Key
Also known as: Blockchain Key, Address Key, Verification Key
A cryptographic key used to receive funds and verify signatures, publicly linked to a private key.
A public key is a cryptographic identifier that works as part of a key pair with a private key. In blockchain, it’s derived from the private key and used to generate wallet addresses. While private keys must remain secret, public keys can be shared to receive funds or verify signatures. Public key cryptography enables secure peer-to-peer transactions, identity verification, and digital signatures without revealing sensitive information. Most blockchain wallets use elliptic curve cryptography (ECC) to generate public keys, which form the basis for decentralized identity and access control.
