I’m building P3, a reputation-based lending marketplace where borrowers earn portable trust from verified actions and repayment history. Stack: React + TypeScript, Supabase (Postgres + RLS), Node backend, Ethereum smart contracts. The idea is to give lenders more underwriting signals beyond a traditional credit score. I’d appreciate feedback on architecture (hybrid on-chain/off-chain scoring), anti-Sybil design, and API structure.
