The Cardano network has reached a significant milestone by successfully deploying its first zero-knowledge (ZK) smart contract on the mainnet.
This achievement utilizes the Plutus v3 ledger language, marking a step forward for the network’s capabilities.
The ZK smart contract Halo2 will allow zero-knowledge applications and partner chains, such as Midnight, to integrate with Cardano.
On Nov. 25, the Input-Output (IO) Research team verified the Halo2 proof on the mainnet for the Ad-hoc Threshold Multi-signatures scheme (ATMS). This scheme successfully validated 50 out of 90 signatures.
The process involved two transactions—one locking the funds and another unlocking them after proof verification. The locking transaction cost 0.16 ADA, while unlocking using Halo2 verification required a fee of 2.03 ADA.
Understanding Halo2
Halo2 is a cutting-edge zk-SNARK proving system that enables secure transaction validation without revealing sensitive details.
