Cardano, known for its layer-1 Proof-of-Stake blockchain, has achieved a milestone in smart contract technology. The blockchain has deployed its first Zero Knowledge (ZK) smart contract on its mainnet, marked by the introduction of Halo2.

This advancement was announced by Sebastian Guillemot, who serves as the lead developer for the protocol. The deployment signifies Cardano's commitment to enhancing privacy and efficiency within its network.

Zero Knowledge smart contracts are expected to offer improved scalability and reduced privacy concerns, which could pave the way for more innovative decentralized applications on Cardano.
