Anyone built something where AI computation get cryptography receipts

We're a small proof-of-useful-work project. The validators don't mine — they verify AI computations (matrix multiplications + activation functions) and get consensus weight for it. The part that matters to you: submit any GEMM workload up to 256×256 and we return the result plus a cryptographic receipt — a SHA-256 commitment chain folded into our ledger state, verifiable by anyone forever. Free, no token, no signup beyond an API key we generate in seconds. Honest limits: we verify GEMM + elementwise activations (GELU/sigmoid/ tanh/exp), not full transformer graphs yet. Attention is on the roadmap. The verification cost curve is published (615ms at 64³ → 157s at 1024³) — we priced our own clamp and labeled every tier. The logs: [pouw-verify] CONFIRMED lines, epoch crossings, claim-decrees folded into the ledger — every claim has a receipt.
