Gladiator Arena (Always-On Colosseum)

Overview

Gladiator Arena is a persistent colosseum loop where bouts resolve autonomously on a fixed schedule. Gladiators take wounds every bout, creating a negative-EV game that nobody self-triggers.

Why AutoLoop Is Structurally Required

Two independent reasons:

1. Timing as attack surface: if an entrant could trigger the bout, they could pick the block in which the VRF reveal lands and only submit if their gladiator benefits.
2. Negative-EV free-rider: every entrant takes 5-20 vitality wounds per bout, only one wins the pot. Rational gladiators reason "let someone else pay gas." Everyone reasons identically, so nobody triggers.

Game Mechanics

• Gladiators: minted at a fixed fee with initial vitality (e.g., 500). Vitality decreases with each bout via VRF-derived wounds.
• Bouts: require 2+ entrants. Each entrant pays an entry fee. Winner is selected proportionally to vitality (weighted VRF).
• Wounds: 5-20 vitality per bout for every entrant, derived from keccak256(randomness, gladiatorId, "wound"). Gladiators hitting minVitality fall.
• Prize pool: entry fees minus protocol rake. Victor receives via pull-payment.

Revenue Model

• Gladiator mint fees (100% to protocol)
• 5% rake on every bout prize pool
• AutoLoop gas fees on each tick
