What is Vitalik Dice?
Vitalik Dice (GasFloor) is a trustless peer-to-peer prediction market that allows users to bet on whether Ethereum's gas prices will reach a specific threshold before a certain block number deadline.
Key Innovation: Unlike traditional prediction markets that rely on external oracles, GasFloor is completely trustless for one side of every bet because it uses Ethereum's native block.basefee opcode (EIP-3198) for atomic, cryptographic verification.
Users can create and take positions on gas price movements with flexible odds through a P2P order book model. When you bet that gas will hit a threshold, settlement is instant and trustless - the blockchain itself proves the outcome.
How It Works
1. Maker Creates an Offer: Bet YES (gas will hit threshold) or NO (it won't). Post your ETH stake, set a gas price threshold in gwei, and a block number deadline. Include a bounty (min 0.003 ETH) to incentivize resolution.
2. Taker Takes the Opposite Side: Multiple takers can partially fill an offer. Only matched portions are at risk - unmatched stakes are returned.
3. Trustless Resolution:
- YES Resolution: Anyone can call
resolveYes() atomically in a block where block.basefee >= threshold. Completely trustless.
- NO Resolution: After the deadline passes, anyone can call
resolveNo() and earn the bounty. Economic incentives ensure resolution.
4. Claim Winnings: Winners receive their stake back plus proportional share of loser stakes. Resolvers claim their bounty separately.
