📈 Proof-of-Training Ledger

The signed learning history of an AI model — written inside consensus, on every block.

FractalAI is the only Layer-1 whose consensus (Proof-of-Useful-Work) writes a real training step into every block header — model id, loss before/after, improvement — Dilithium-signed by the validator. The chain becomes an append-only, tamper-evident ledger of a model’s loss curve, re-verifiable by anyone against the public RPC.
