zKeeper won first prize at the ETH Istanbul ’23 Mina Hackathon This initiative employs Mina to deploy the Appchain Mixer, a ZK-rollup solution designed to enable confidential transactions while seamlessly integrating KYC/AML systems. By harnessing zero-knowledge proofs on the Mina platform, users can engage in secure and compliant transactions with heightened privacy features. In the long term, our strategy involves constructing a cross-chain mixer that allows users to deposit in Mina and withdraw from Layer 2 solutions such as Starknet, Optimism, or others. This is achieved through the combined use of lambda-class/mina_bridge and storage proofs technology. Technical Implementation: o1js, leveraging its cryptographic capabilities, plays a crucial role in implementing zero-knowledge proofs to enhance privacy and security. The project’s frontend is built on Next.js, a React framework, ensuring a modular and efficient user interface. Protokit serves developers by facilitating the construction of zero-knowledge, interoperable, and privacy-preserving application chains.
