Cardano, a leading Layer-1 Proof-of-Stake (PoS) blockchain, has introduced a major development in its smart contract infrastructure. Developer Sebastian Guillemot announced that "Halo2," the first Zero Knowledge (ZK) transaction, is now live on the Cardano mainnet.

This advancement reflects Cardano's ongoing evolution in enhancing blockchain scalability and privacy through ZK proofs. Guillemot also shared the transaction hash, "71579b77ab7d974eb31ef1b50d58f14f2ceac2bcf540aac50f777f56a8f24bff," providing evidence of the live transaction.

The launch of ZK smart contracts is considered pivotal for Cardano, potentially accelerating adoption and offering improved privacy and security for blockchain users.
