TrustLayer - Reputation Infrastructure for Qubic

TrustLayer is decentralized reputation infrastructure for Qubic's DeFi ecosystem, solving a fundamental problem: how do protocols assess user trustworthiness? THE PROBLEM: Every lending protocol, DEX, and marketplace launching on Qubic must evaluate user risk. Without reputation data, all users are treated identically, forcing full collateralization regardless of track record. This creates capital inefficiency, higher friction, and poor user experience. THE SOLUTION: TrustLayer evaluates wallet behavior using a multi-signal scoring model organized into 4 core categories (Account Maturity, Transaction Patterns, Behavioral Trust, Network Effects). The POC uses simulated data for these categories to generate transparent reputation scores (0–1000), enabling risk-based rates, safer lending, and early fraud detection. POC DEMONSTRATION: The working prototype includes 5 realistic user profiles. Alice (score 1000) receives 3% APR and 10x leverage. Bob (score 211) receives 12% APR and 1.5x leverage. Same protocol, different reputation—dramatically different outcomes. WHY INFRASTRUCTURE: TrustLayer is not a DeFi app; it is foundational middleware. Every lending platform, DEX, marketplace, and DAO on Qubic will need reputation scoring. By standardizing reputation at the protocol layer, TrustLayer enables shared, portable trust across the entire ecosystem. QUBIC INTEGRATION: This POC validates the scoring logic and demo experience. Qubic’s computational model enables complex on-chain scoring that would be prohibitively expensive on gas-based chains. Smart contract deployment of Q-Rep to the Qubic testnet is planned immediately post-hackathon. WHY NOSTROMO: We have validated the concept with a functional POC demonstrating clear ecosystem need. We are ready for Qubic testnet deployment and seek Nostromo’s support for ecosystem alignment, protocol partnerships, and launch guidance to make this core infrastructure production-ready.
