Zero-Knowledge Proofs

What are ZK Proofs?

A zero-knowledge proof is a cryptographic method by which one party (the prover) can prove to the other party (the verifier) that the information they need to validate is correct without revealing any information other than the validity of it. In doing so, this keeps any related data private and helps prevent the risk of fraud.

For example, if someone needs to use your driver's license to check your age, a dApp built with ZK proofs can provide a credible validation without compromising your personal information, like your name or home address.

Keeping Crypto Out of Smart Contracts

Kadena’s distinct security architecture and integration of Zero-Knowledge proofs keep crypto out of smart contracts. This principle minimizes the risk of vulnerabilities within smart contract logic, while the use of Zero-Knowledge proofs for transaction validation further strengthens security without compromising integrity. With Kadena, developers can confidently focus on innovation, knowing their smart contracts are secure and reliable.

ZK on Kadena

Argument Partnership

Kadena has partnered with Argument, an innovative leader in the ZKP field, to build out a Zero-Knowledge Proof tech stack on Kadena’s blockchain that will pave the way for cross-chain zero-knowledge (ZK) proof messaging. The partnership’s roadmap includes the development of a ZK bridge from Ethereum to Kadena, a ZK light client, and Wormhole integration.

Milestones of the Partnership

Opact wallet

Kadena-grantee Opact Wallet is a strong example of how ZK technology is being used on Kadena. Opact provides privacy and security for blockchain transactions while maintaining institutional compliance, as it prevents malicious activities such as money laundering and financing terrorism. Opact was developed by Hack-a-Chain, a Brazilian Web3 laboratory specialized in zero-knowledge and other advanced cryptographic techniques
