Cardano has completed a network upgrade aimed at improving network security and Plutus cross-chain interoperability. This upgrade enhances encryption and allows developers to develop cross-chain applications based on Plutus, the Cardano smart contract platform. Foresight News previously reported that the Cardano development company Input Output and the Cardano Foundation submitted a proposal to upgrade the Cardano mainnet to the protocol V8 update, which is scheduled to take effect at 5:44:51 on February 15, 2023, Beijing time. Input Output stated that this upgrade will bring new encryption primitives to Cardano, encouraging better interoperability with Plutus and secure cross-chain DApp development.
