Keypair
Also known as: Crypto Key Pair, Public/Private Key Pair, Blockchain Credential Set
A cryptographic set of private and public keys used to secure and authenticate blockchain transactions.
A keypair in blockchain consists of a private key and a corresponding public key. The private key is a secret string that authorizes transactions, while the public key (and its derived address) is shared to receive funds. Blockchain wallets generate keypairs based on cryptographic algorithms like ECDSA or EdDSA. The security of the keypair ensures that only the rightful owner can sign and send transactions. Losing the private key results in permanent loss of access, making secure storage critical. Keypairs are foundational to blockchain identity, digital signatures, and non-custodial wallets.
