Evidence of feasibility
What the TRACE prototype demonstrated
TRACE has been built and tested. Here is what the prototype proved, what it did not prove, and what the results mean for the question of scaling.

Research prototypes are often dismissed as academic exercises. TRACE was designed from the outset to answer a practical question: is this technically feasible, and does it work under realistic conditions? The testing results provide a clear answer on both counts.
The prototype was built using real technology — IOTA's public blockchain network, an actual PostgreSQL database, and working software agents that apply real EU compliance rules. It was tested with synthetic datasets calibrated to reflect realistic Kenyan agricultural supply chain conditions: pesticide application patterns, GPS coordinates in Kirinyaga County, temperature profiles from refrigerated transport.
The system correctly approved a shipment with full, clean data. It correctly blocked a shipment where pesticide levels exceeded EU limits. It correctly blocked a shipment where farm GPS was missing. And when the IOTA network was temporarily unavailable, the system entered a graceful queued state — no data was lost and no crash occurred.
Fraud detection was also confirmed: when a saved record was deliberately altered to simulate tampering, the system immediately detected the fingerprint mismatch and flagged the record as compromised.
The key finding for funders and policy makers is this: the technical feasibility of using a feeless DAG-based ledger with autonomous compliance agents for ESG certification has been demonstrated. The cost barrier that makes conventional blockchain solutions impractical for smallholder farms does not exist with IOTA.
