Truth Onchain

COO let anyone assert any verifiable claim or data on-chain.

How It Works

Optimistic by design.
Honest by default.

01

Statement

Anyone proposes a statement as true — a price, an event, a transaction. The protocol accepts it by default.

02

Challenge Period

A window opens for the world to review the statement. If nobody raises a hand, it passes as verified fact.

03

Dispute

Anyone who knows the truth can challenge the statement. The protocol only needs one honest person to catch a lie.

04

Voting

COO token holders are the final arbiters. When a dispute reaches this stage, the community votes — and their verdict is the truth.
