AI-powered trust infrastructure for African commerce built with GenLayer # Trust Africa Trust Africa is a GenLayer-native trade trust application. Its intelligent contract is the only authoritative source for trades, AI validation, disputes, trust passports, trust reports, and settlement accounting. ## Architecture - `contracts/trust_africa_intelligent_contract.py` owns all authoritative state. - `frontend/index.html` uses `genlayer-js` directly. Reads call contract view methods; writes are signed by the connected browser wallet and finalized before the UI reads the resulting state. - `backend/server.py` is an optional read-only HTTP facade. It calls the deployed contract through `genlayer-py` and rejects every state-changing request. - `backend/trust_engine.py` is retained only as a deterministic historical demo used by demo tests. It is not imported by the production server or browser. The contract uses `gl.nondet.exec_prompt` inside `gl.eq_principle.prompt_comparative` for `validate_trade`, `resolve_dispute`, and `issue_trust_passport`. No deterministic keyword logic replaces consensus. ## Contract methods used by the application Wallet-signed writes: - `create_trade(trade_id, buyer, buyer_address, seller, seller_address, product, amount, evidence)` - `validate_trade(trade_id, evidence)` - `resolve_dispute(trade_id, buyer_claim, seller_response, evidence)` - `issue_trust_passport(business)` Finalized reads: - `get_trade(trade_id)` - `get_trust_passport(business)` - `get_full_trust_report(trade_id)` The caller must be the stored buyer or seller to create, validate, or resolve a trade. Terminal outcomes (`APPROVED`, `REJECTED`, `RELEASE_FUNDS`, and `REFUND_BUYER`) set `finalized` and cannot be processed again. Manual review keeps a trade open and accounts its held amount once, even across repeated reviews. Settlement fields are accounting records only. This repository does **not** transfer USDC or another token. ## Configuration After deploying the contract, set these two meta tags in `frontend/index.html`: ```html ``` …
