An optimistic oracle is a mechanism that assumes a proposed market outcome is true unless it is disputed within a specific challenge period. It prioritizes speed and cost-efficiency for undisputed results.

Why it matters on AGON

Every market on AGON, from the World Cup winner to the next ETH price target, requires a definitive result to settle bets. This result comes from an oracle. While AGON currently uses a centralized admin oracle for maximum speed at launch, our long-term infrastructure, the Oracl3 Protocol, is designed around an optimistic model.

This approach, pioneered by projects like UMA, allows for resolving any verifiable event without relying on a single, centralized feed. It creates a system of economic guarantees where truth is the default path. For users, this means a future of credibly neutral settlement across a vast range of markets on /markets, secured by economic incentives rather than a single administrator's word.

How to apply

The optimistic oracle process is straightforward.

  1. Proposal: A proposer submits an outcome for a settled market and posts a bond.
  2. Challenge Window: A pre-defined time period opens (e.g., 2 hours). During this window, anyone can dispute the proposed outcome by posting their own bond.
  3. Resolution: If there is no challenge, the proposed outcome is accepted as truth, and the market settles. If a dispute is raised, it escalates to a more robust (and slower) resolution mechanism, like a DAO vote, to determine the correct outcome. The winner takes the loser's bond.

This design prevents any single party from getting a user rekt by settling a market incorrectly. The economic cost of a failed dispute ensures that challenges are only raised for legitimate errors.
