1/10: The next Cardano upgrade targeted for February will bring new built-in functions to #Plutus, the smart contract programming language for the #Cardano blockchain, to support ECDSA and Schnorr cryptographic signatures to make it easier for developers to build cross-chain apps
2/10: Different blockchains use different cryptographic signature methods, such as ECDSA and Schnorr signatures, which are used in #Bitcoin and #Ethereum, among others.
3/10: #Cardano uses the Edwards-curve Digital Signature Algorithm (EdDSA) with elliptic curve Curve25519 as its base curve (Ed25519) which is fast, secure and small in size, but not compatible with ECDSA and Schnorr.
4/10: This upgrade will bring greater interoperability and secure cross-chain #DApp development to #Cardano, making it easier for developers to work with other blockchains. iohk.link/3kqVI7U
5/10: Developers would otherwise need to spend extra time, effort, and funds to implement ECDSA and Schnorr over the SECP elliptic curves in #Plutus, increasing potential security risks and using an unrealistic amount of resources.
6/10: New built-in functions coming to #Plutus will support these signatures to make it easier for developers to build cross-chain applications and provide the highest level of security.
7/10: Preparations have been underway for some time across the entire #Cardano ecosystem, with positive results from integration testing.
8/10: This technology is now close to being deployed on the #Cardano mainnet, with over 80% of block-producing nodes running the required new node.
9/10: Exchanges have already been notified of the upgrade and #DApp developers have been polled to ensure compatibility. The upgrade is proposed tentatively for February 14, 2023
10/10: IOG & @Cardano_CF will keep the community informed of progress so stay close to IOG and CF channels for the latest updates.
