Cardano Network Deploys First Zero-Knowledge Smart Contract on Mainnet
The Cardano network has achieved a significant milestone by successfully implementing its first zero-knowledge (ZK) smart contract on the mainnet using the Plutus v3 ledger language.
Integration of ZK Smart Contract Halo2
- The ZK smart contract Halo2 enables zero-knowledge applications and partner chains like Midnight to connect with Cardano.
- The Input-Output (IO) Research team verified the Halo2 proof on the mainnet for the Ad-hoc Threshold Multi-signatures scheme (ATMS).
- 50 out of 90 signatures were successfully validated in this process.
Understanding Halo2
Halo2 is a cutting-edge zk-SNARK proving system that allows secure transaction validation without revealing sensitive details.
Key Features of Halo2
- Halo2 builds upon the PLONK protocol, optimizing efficiency and flexibility in zk-SNARK applications.
- The component-based structure of Halo2 breaks down functions into modular elements for easier adaptation to cryptographic needs.
- It eliminates the need for a trusted setup, addressing security risks and logistical challenges present in traditional zk-SNARK systems.
- Halo2 supports recursive proofs, dividing computations into smaller segments for efficient proof aggregation and enhanced performance.
Enhancements and Advantages of Halo2
- Halo2 aims to reduce overhead costs and improve proof generation and verification speed for real-world applications.
- Developed as an extension and improvement of the original Halo protocol, Halo2 enhances the overall security of zero-knowledge proofs.
