Asphodel Onchain Randomness Cuts Bias Costs to 0.8Ξ

Asphodel's Prologue processes game state end-to-end onchain. Randomness uses RANDAO, extended to 8191-block windows via EIP-2935, costing ~15k gas overhead. Withholding bias costs ~0.056Ξ per slot; 16 slots (0.8Ξ) rigs 1-in-4.3B lottery odds. Systems break EIP-4399's 4-epoch lookahead for UX, relying on economic pricing instead.
