Cardano 
$1 has successfully deployed its first zero-knowledge (ZK) smart contract on its main network using the Halo 2 proof system. This development expands the potential use cases by introducing advanced scalability and privacy capabilities within the Cardano ecosystem.
Cardano’s Developments in November
November proved to be a busy month for Cardano, marked by numerous announcements of developments and integrations. These advancements were reflected in a 5% increase in the price of ADA, which reached $1.01, a level not seen since mid-2022.
Features of Halo 2 Technology
Halo 2 is an advanced zk-SNARK system integrated into Cardano, offering non-interactive setup, iterative proofs for scalability, and enhanced interoperability. The implementation of Halo 2 helps address fundamental challenges in blockchain technology.
We have more work to do. However, the tests conducted by IO Research represent a significant step in the utilization of zero-knowledge proofs with Cardano, bringing a powerful combination of scalability, efficiency, and enhanced security.
Input Output HK emphasized the benefits this development brings to the Cardano ecosystem, stating that further development is needed to fully realize the potential of zero-knowledge technology.
Additionally, the integration of Halo 2’s PLONK zk-SNARK framework provides greater flexibility and efficiency for cryptographic processes. This contributes to reduced operational costs and accelerates the generation and verification of proofs.
In conclusion, the deployment of Cardano’s zero-knowledge smart contract on the main network indicates a significant advancement in blockchain technology. The integration of Halo 2 enhances Cardano’s capabilities in scalability and security, while the increase in ADA’s price signals a positive reception for the ecosystem.
