Elliptic Curve Cryptography (ECC)
Public-key cryptography using elliptic curves for equivalent security with smaller keys — the cryptographic substrate of digital asset systems.
Definition
A public-key cryptography system based on the algebraic structure of elliptic curves over finite fields. ECC provides equivalent security to RSA with dramatically smaller key sizes — a 256-bit elliptic curve key provides security comparable to a 3,072-bit RSA key. Bitcoin and most digital asset systems use the secp256k1 curve. ECC is the cryptographic substrate upon which private keys, public addresses, and digital signatures in the sovereignty stack are built.
