-The Valentine (or SECP) upgrade is Cardano’s intra-era hard fork that follows the [Vasil upgrade](https://docs.cardano.org/cardano-testnet/about/testnet-introduction). Valentine is a small and focused semantic change to the ledger, which brings new built-in functions to Plutus to support SECP elliptic curves (ECDSA and Schorr). Although an intra-era hard fork requires a hard fork combinator event, it does not change the ledger era, which means that this is an upgrade to the Babbage era (Vasil functionality).

 ECC is a popular primitive for developing cryptographic protocols and secure applications using custom encryption and decryption algorithms validated by digital signatures. ECC provides the same level of security as other mechanisms while using shorter keys and signatures.
 
-There are different elliptic curves one can use, with secp256k1 as one of the options. Each of these curves differs in its parameters. The secp256k1 curve provides two common signature schemes – ECDSA and Schorr.

 Cardano uses the Edwards-curve Digital Signature Algorithm (EdDSA) with elliptic curve Curve25519 as its base curve (Ed25519). Ed25519 is designed to be resistant to certain types of cryptographic attacks, making it a secure choice.
