Cardano Unlocks New Features as First Zero-Knowledge Smart Contract Goes Live on Mainnet
- Cardano achieved a key milestone by deploying its first zero-knowledge (ZK) smart contract on the mainnet using the Halo 2 proving system.
- November brought multiple advancements for Cardano, with ADA’s price rising 5% to US$1.01, a level not reached since mid-2022.
- Halo 2, an advanced zk-SNARK system integrated into Cardano, offers a trustless setup, recursive proofs for scalability, and enhanced interoperability.
Cardano (ADA) has achieved a significant technical milestone by successfully implementing its first zero-knowledge (ZK) smart contract on the mainnet. This development introduces the Cardano ecosystem’s advanced scalability and privacy capabilities, expanding its potential use cases.
Cardano Takes Off
November has been a very busy month for Cardano with many developments and integrations announced by its parent company. These advancements are reflected in ADA’s price, currently at US$1.01 (AU$1.56), representing a 5% surge from yesterday, as per data from CoinMarketCap.
It should be noted that ADA hasn’t seen this price since mid-2022. So, yeah, it’s quite the milestone for the cryptocurrency.

Going back to the announcement, the transaction was conducted by Input Output, Cardano’s core development team, using the Halo 2 proving system for zero-knowledge verification.
This process involved two main transactions: the initial transaction locked funds, and the second, verified through a ZK proof generated by Halo 2, unlocked the funds. The entire process incurred a transaction fee of just 2.03 ADA, roughly US$1.90 (AU$2.9).
While the deployment represents a significant milestone, IOHK clarified that further development is needed to fully unlock the potential of zero-knowledge technology within Cardano’s ecosystem:
We still have more work to do. But this test by IO Research represents a significant step forward in the use of zero-knowledge proofs with Cardano, bringing with it a powerful combination of scalability, efficiency, and further enhanced security.
What is Halo 2?
Halo 2 is an advanced zk-SNARK (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge) proving system designed to validate transactions securely without revealing underlying data. Its integration into Cardano enhances both privacy and scalability, addressing key challenges in blockchain technology.
One of Halo 2’s defining features is its trustless setup, which eliminates the need for traditional trusted setups, mitigating security risks and simplifying deployment.
Input Output highlighted the importance of recursive proofs, which Halo 2 supports. They basically divide complex computations into smaller, verifiable tasks, improving capability and enhancing interoperability, a crucial aspect for applications in a growing blockchain ecosystem.

Additionally, Halo 2 incorporates the PLONK zk-SNARK framework, optimising efficiency and providing greater flexibility for cryptographic processes. This reduces operational overheads and accelerates proof generation and verification, making it suitable for practical use cases.
