How Perpetua works
From a claim to a settled price.
Four steps turn an open question into a continuously priced, evidence-backed entry.
- 01
Submit a factual claim
Anyone can propose a falsifiable statement, attach the evidence behind it, and seed its market with NEAR collateral. The claim becomes a page in the encyclopedia.
- 02
Let the market price its confidence
Traders buy and sell YES and NO shares in a continuous automated market. The YES price is the market's running confidence, and it moves with every trade.
- 03
Resolve contested claims with an attested AI jury
When a claim is disputed, a challenger posts a bond to escalate it. NEAR AI Cloud's attested jury reviews the evidence and returns a verdict with an attestation hash recorded against the market.
- 04
Settle the market
After a challenge window in which the ruling can be counter-challenged, the market settles and winning positions are redeemed from the collateral vault.

Verification architecture
Four layers between a claim and a verdict.
Perpetua runs on NEAR Protocol alone. Parameters shown below are read from the active configuration.
- 01
Evidence-backed claims
Every claim is a single, falsifiable statement stored on-chain with its evidence links. The encyclopedia article is generated from the claim, its evidence and the current market, and its page hash is attested so readers can check what they are reading.
Evidence sources 25Claims 24 - 02
Continuous prediction markets
Each claim has a perpetual binary market. YES and NO shares trade against an automated market maker, so confidence is always priced and always moving, with no order books and no waiting for a round to close.

AI jury
A contested claim can be escalated by posting a bond. The market freezes at its current price while NEAR AI Cloud's attested jury of models weighs the evidence. Each vote and the combined verdict are recorded with an attestation.

On-chain settlement
A ruling is not final the moment it lands. It opens a challenge window in which it can be counter-challenged at a higher bond. Once the window closes, the market settles and holders redeem from the collateral vault on NEAR.
