Ed25519 (tz1…)
An EdDSA signature scheme that uses SHA-512 and Curve25519. This is the most commonly used signature scheme in Tezos.
Secp256k1 (tz2…)
Secp256k1 describes the parameters used in the ECDSA algorithm. The default signature scheme in Bitcoin.
P-256 (tz3…)
A prime elliptic curve standardised by NIST. Also known as secp256r1 and considered a sibling to secp256k1.
