Cloak | Solana Privacy Layer

DeFi, Consumer Apps, Infrastructure

Privacy has become the last missing piece of the Solana ecosystem and Cloak is here to fill that gap. Private payments on Solana: deposit from one wallet, withdraw to different ones, and the link between them is hidden. Miners secure and maintain the network’s privacy by submitting valid work and generating transaction volume, ensuring that activity never depends solely on user traffic. On-chain, the network only sees “pool → recipient,” never “sender → recipient,” while every new deposit and mined withdrawal expands the overall anonymity set. Cloak keeps the system running smoothly and decentralized — users transact privately, miners earn rewards, and Solana stays fast and transparent where it matters. Solana-native • mobile-friendly and soon on dApp Store • fully open-source • built during Cypherpunk + IslandDAO. Access: https://www.cloaklabz.xyz/

CompliFi is a decentralized RegTech protocol on Solana that brings regulatory compliance on-chain without compromising decentralization. It enables DeFi applications to verify KYC and risk requirements seamlessly before executing transactions. By integrating with the Solana Attestation Service (SAS) and the Range Risk Oracle, CompliFi validates user attestations and wallet risk scores in real time. For the hackathon MVP, mock attestations and risk data simulate these integrations. Each transaction is verified against configurable compliance policies (e.g., “KYC verified” and “risk score < 3”) and logged both on-chain and off-chain for transparency and auditability. CompliFi empowers DeFi developers to build compliant dApps that align with financial regulations, bridging the gap between decentralized finance and real-world compliance — all through trustless, programmable enforcement.

Computeshare

DeFi, Infrastructure

This project is a Decentralized Machine Data Exchange platform designed to bridge the gap between those with vast amounts of underutilized machine data and those who desperately need high-quality datasets to train heavy AI/ML models. How it Works: Data Monetization: Data holders (individuals or companies with surplus data) can securely tokenize or lease access to their datasets to earn revenue. Privacy-Preserving Computation: To ensure data privacy, we leverage Federated Learning. Instead of moving the sensitive data, the AI model is sent to the data's secure location for training. Only the resulting model weights (the knowledge) are transmitted back to the user, ensuring the raw data never leaves the owner's control. The project transforms "sleeping" data assets into an income stream while fueling the next generation of data-intensive AI development.
