BTS — Beat The System
A parimutuel prediction-market engine designed so that bets lock before an event window — removing the last-second sniping that advantages high-frequency bots.
How it works
1
Bet before the lock
Each market has an immutable cutoff. At the lock time, new bets are rejected on-chain — no late entries, no reordering games.
2
Shared parimutuel pool
YES and NO stakes form one pool. Odds are simply the pool ratio; a 6% fee is taken from the pool at settlement.
3
Oracle settlement
After the observation window, the market resolves from the defined rule. Winners claim pro-rata; one-sided or unresolved markets refund in full.

Status
- Built & verified locally: parimutuel smart contracts and an autonomous settlement daemon, tested end-to-end against a local chain.
- Not enabled: real deposits, real-money wagering, and a live public market.
- Deliberately untested claims: we do not claim BTS is "HFT-proof" or that it neutralizes paid-feed advantages — that requires experiments we have not yet run.
