Input Output Global (IOG), the organization behind the Cardano blockchain, has launched a Valentine’s Day update for its Standards for Efficient Cryptography (SECP) primitives on the network’s mainnet.
With the updatedevelopers can now use a wider range of native multi-signature designs to build secure and cost-effective decentralized applications (DApps).
Happy Valentine day. 💙
We are happy to announce that the #valentine upgrade – support for #Plutus SECP Cryptographic Primitives – is now live on the #Cardano main network.

Cardano’s Valentine’s Day upgrade is now live
The upgrade took place on February 14 at 21:44 UTC, at the start of epoch 394 around absolute slot height 84844800 and estimated block height 8403208.
IOG shared that the variance in cryptographic algorithms and signature schemes across blockchains led to the upgrade.
Being the two most popular signature schemes, Elliptic Curve Digital Signature Algorithm (ECDSA) and Schnorr are used in Bitcoin, Ethereum and Polkadot blockchains.
On the other hand, the Cardano network uses the Edwards Curve Digital Signature Algorithm (EdDSA) with the elliptical curve Curve25519 as its base curve (aka. Ed25519) alongside Ripple, Monero and others.
The difference in cryptographic algorithms means Cardano dApp developers should validate ECDSA and Schnorr signatures when working with other blockchains. This increases security risks and requires significant resources, hence the cryptographic primitives.
“Native support for SECP now promotes interoperability between chains while ensuring the highest level of security. With the #Cardano #Valentine upgrade, developers can now easily build secure, reliable and cost-effective cross-chain DApps,” IOG said.
Support for ECDSA and Schnorr signatures
Notably, only Ed25519 was provided as a built-in function for Plutus, which is the native language of Cardano’s smart contract platform.
IOG has now integrated new functions into Plutus to support ECDSA and Schnorr signatures. Building cross-chain apps will now be less expensive and time-consuming, as developers have access to a wider range of Cardano-native multi-signature designs.
“Interoperability is key to blockchain growth. As more and more DApps are built on #Cardano, it is essential that they are not siled into a single ecosystem, allowing users to interact with different blockchains and access a wider range of services,” IOG added.
