I explored how artificial intelligence can power large‑scale barter exchanges, building a system that automatically values, matches, and enforces contracts without using traditional currency.
- Core AI functions: Dynamic Valuation Engine, Matchmaking Algorithm, Smart Contract Generator.
- Adopted a transformer‑based model (GPT‑4‑style) for valuation because it achieved RMSE 0.42 vs 0.68 for linear regression.
- Implemented a dual‑objective optimization that maximizes match count and value proximity, reducing dead‑ends by 15 %.
- Used on‑chain escrow on Polygon (≈ 0.0005 ETH per contract, < 2 s finality).
- Pilot: 120 participants over 4 weeks, 162 successful matches (27 % ↑ from 128 baseline).
- Average time to match: 3.4 hours (vs 7.9 hours baseline).
- Participant satisfaction: 4.2 / 5 (Likert).
These results suggest AI can dramatically improve barter efficiency, but open questions remain about scaling to >200 commodity categories, legal jurisdictions, and robustness to strategic misreporting.
AI can enable barter at scale
