Overview
What is Yiling?
Yiling is an oracle-free prediction market protocol — and also a live product. We run our own prediction markets on Monad, and the same infrastructure is open for anyone to build on.
Based on peer-reviewed research from Harvard (published at ACM EC 2025), the protocol implements the SKC mechanism — a mathematically proven system where truth emerges from game theory, not external oracles.
Two Ways to Use Yiling
1. Trade on Our Markets
Yiling runs live prediction markets on Monad. You can explore markets, submit your predictions, and earn rewards for accuracy — no oracle needed.
2. Build Your Own
The same infrastructure powering our markets is available for you to build on. Create your own prediction markets, governance systems, dispute resolution, or anything that needs decentralized truth discovery.
Why It Matters
Every prediction market today depends on an external oracle to decide what's true. In March 2025, a UMA token holder manipulated a Polymarket resolution by controlling 25% of voting power.
Yiling removes the oracle entirely:
- Self-resolving — markets close themselves through probabilistic stopping
- Truthful equilibrium — honest reporting is a Perfect Bayesian Equilibrium
- Cross-entropy scoring — earn rewards proportional to your accuracy
- Bond-based — every prediction requires a deposit, creating skin in the game
- Live now — deployed on Monad with low gas fees
