Agentic AI fraud prevention for African mobile money. 6 CAMARA APIs via Nokia Network as Code with hash-chained audit. Africa Ignite Hackathon 2026 (GSMA + Nokia). # TrustMesh **AI-Orchestrated Network Trust Scores for Africa's Mobile Money Economy** TrustMesh is an agentic AI fraud-prevention platform that orchestrates 6 CAMARA APIs through Nokia's Network as Code to produce a real-time composite trust score for every mobile money transaction — with tamper-evident audit certificates regulators can independently verify. > Africa Ignite Hackathon 2026 — GSMA + Nokia > Theme 6 (Open Innovation) · Team `akhona_3761` --- ## The problem Across Africa, mobile money fraud costs around **$4 billion every year**. Roughly **70% of it involves a SIM swap, device change, or stolen identity** — signals operators already have, but no one stitches together at the moment of risk. Mama Thandi runs a spaza shop in Khayelitsha. Last month a customer asked her to send R10 000 — the SIM had been swapped four hours earlier. The transfer cleared. The money was gone. TrustMesh exists so that the next R10 000 doesn't. --- ## How it works ``` Transaction → Orchestrate 6 CAMARA APIs → Composite trust score (0–100) → Decision: APPROVE / FLAG / BLOCK → LLM-explained reasoning → Hash-chained audit certificate ``` | Signal | Weight | Source | |---|---|---| | SIM Swap | 30% | CAMARA SIM Swap API | | Device Swap | 20% | CAMARA Device Swap API | | KYC Match | 20% | CAMARA KYC Match API | | Number Verification | 10% | CAMARA Number Verification (OIDC) | | Location Verification | 10% | CAMARA Location Verification API | | Device Status | 10% | CAMARA Device Status API | Every decision is locally validated against domain-specific intents and recorded in a hash-chained audit chain. The audit certificate from a USSD call is the same certificate a regulator inspects via REST — provable consistency across channels. --- ## Four channels, same engine | Channel | Audience | Status | |---|---|---| | **REST API** | Fintechs, mid-market lenders | Live | | **USSD** | Spaza shops, anyone with a feature phone | Live (Africa's Talking) | | **OIDC** | User-bound …
