ERC-8004 Identity

On-chain agent reputation

Meridian holds a soulbound identity token on Arc's IdentityRegistry (ID 18359). After every market resolves, a Brier-score accuracy event is written to the ReputationRegistry — a verifiable track record any buyer agent can check before paying for signal.

score = round((1 − brierScore) × 100)
brierScore = (prediction − outcome)²
→ recorded on every resolution
