Bob wants proof that the key is genuine before paying, while Alice doesn't want to reveal the key before receiving payment.</p> <p>Traditional escrow mechanisms don't completely solve this problem.</p> <p>The zk-barter project explores combining cryptographic verification with smart-contract escrow to make such exchanges more trust-minimized.</p> <h2> Technologies and concepts </h2> <p>The project explores:</p> <ul> <li>Solidity smart contracts</li> <li>Zero-Knowledge Proofs (ZKPs)</li> <li>Groth16 proof systems</li> <li>libsnark</li> <li>Cryptographic commitments and verification</li> <li>Smart-contract-based escrow</li> </ul> <h2> Current development </h2> <p>This is an ongoing research and prototype project. The cryptographic circuit implementation and integration still require substantial work. It is not production-ready or independently audited.</p> <p>I'm sharing the source code publicly to document the project and its development.</p> <p><strong>Explore the repository:</strong> <a href="https://github.com/Rushidev-Jain/zk-barter" rel="noopener noreferrer">https://github.com/Rushidev-Jain/zk-barter</a></p> <p>Feedback and technical discussion are welcome.</p> cryptography smartcontract forntier solidity
