Cardano has taken a significant step forward in smart contract development, launching its first Zero Knowledge (ZK)-based smart contract on its mainnet. Sebastian Guillemot, the protocol’s lead developer, shared details of this innovative contract, and this solution, called Halo2, is expected to form the basis for the creation of zkApps and partner chains on the mainnet with Plutus v3 support.
Cardano aims to increase transaction accuracy and offer lower transaction fees with ZK-based smart contracts. Input Output Global (IOG) has successfully completed the Halo2 ZK Proof verification process, developing an efficient method for Ad-hoc Threshold Multi-Signatures Schemes (ATMS). In the system, funds are locked with the first transaction, then the second transaction is resolved with Halo2 proof. The locking fee in this transaction is set at 0.16 ADA and the opening fee is set at 2.03 ADA.
This innovation provides Cardano with a competitive advantage by solving scalability and security issues in existing blockchain infrastructures. In addition, the cost-effectiveness of the system helps the platform compete with other blockchain projects.
Cardano, which has been constantly improving itself with many updates in recent years, is working on various projects to improve the user experience. One of these projects, the gamified test network called Hydra Doom, is used to involve users in the process and increase participation. In addition to strengthening Cardano's technical infrastructure, this initiative also aims to bring new users to the ecosystem.
As Cardano offers more innovative solutions compared to its competitors, the platform’s future growth potential increases. Halo2’s low transaction fees may encourage users to opt for this network. However, the value of ADA Coin is negatively affected by the general market downtrend.
Cardano’s first ZK-based smart contract, Halo2, has made significant progress in the blockchain space by improving the security and scalability of the network. This achievement brings Cardano one step closer to its goal of strengthening its position in the industry with its innovative solutions.
