    Subgraph MCP

    MCP server that lets AI query any The Graph subgraph

    5th0G

    Subgraph MCP is a Model Context Protocol server bridging AI assistants and The Graph's decentralized indexing protocol. It lets large language models query on-chain data in natural language without writing GraphQL manually — simply ask and get blockchain data back. Built fully vibe-coded at ETHcc[9], it placed 5th in the 0G track.

  • Phare app hero — interactive globe showing orbital satellite name registrations

    Phare

    Decentralized identity and namespace for orbital satellites

    1stFuture Society2ndENS2ndSpaceComputer

    Phare is a decentralized protocol that brings blockchain-based identity and naming to orbital satellites. By anchoring satellite namespaces on ENS and using smart contracts for ownership verification, Phare enables trustless coordination of space infrastructure at a global scale. It won 1st place in the Future Society track, 2nd place sponsored by ENS, and 2nd place sponsored by SpaceComputer at ETHPrague 2026.
