Verify

Verify lets the public check the chain without an account. Anyone

with an anchor link can confirm that the documented hash exists on

both chains and that the signing key chain is intact.

Maths

Reputation is computed across five dimensions across anchored

events in the trailing 365 days. Each dimension defaults to 75;

anchored events move the relevant dimension by 1 to 5 points; the

score floor is 0 and the ceiling is 100. The dimensions are

sourced from the Reputation model in prisma/schema.prisma and

are the canonical names used everywhere in the platform.

Five dimensions

• responsiveness: do they respond inside the document's

response windows?

• reliability: do they deliver what they committed to?
• timeliness: do they hit deadlines?
• collaboration: do they engage constructively when changes

are needed?

• documentation: do they keep the record honest with evidence

and updates?

Anchored events

Every reputation event has an anchor when it is item-scoped (the

BlockchainAnchor schema requires an itemId). A counterparty

can fetch those events, verify each anchor independently, and

reconstruct the score without trusting Nebula's API.

Org-scoped reputation events (no itemId) are recorded with the

audit trail but are not chain-anchored individually; they exist

to capture cross-project signals like anti-gaming actions.
