Cardano launches ZK smart contract: Cardano has reached a significant milestone by launching its first ZK smart contract. This transaction was executed by Input Output with Halo 2 ZKSnark technology. It’s a major step forward in the scalability and security capabilities of the Cardano network.

Reasonable transaction cost: The first ZK smart contract transaction costs only 2.03 ADA, about 1.90 USD, indicating a reasonable cost for using the new technology. Input Output Holdings sees this cost as “reasonable” and feasible for users.

Outstanding features of Halo 2: Halo 2 allows for the creation of repeat proofs, simplifying complex processes in the Cardano blockchain. This feature is crucial for scalability and increasing network flexibility.
