All-Pay Auction Inefficiency

Theorem: Traditional bug bounties are all-pay auctions, which are provably inefficient. Pooled bounties achieve higher total effort.

The Problem with Traditional Bounties

In a standard bug bounty, every hunter expends effort (compute, time) but only the first valid finder gets paid. This is an all-pay auction — all participants pay, one wins.

The Math (Baye et al., 1996)

In an all-pay auction with n symmetric players:

Expected effort per player = B / n²    (for 2 players)
Total effort = B × (n-1) / n²

As n → ∞, total effort → 0 per player (free-rider problem)

Consequences

Rational hunters underbid — they spend less effort than would be socially optimal because the probability of being the first finder decreases with more competition. This means:

• Codebases get less thorough audits than they should
• Hunters specialize in "quick wins" rather than deep analysis
• Subtle, complex vulnerabilities go undiscovered

Prowl's Cooperative Model

In a Pool, sponsors and the operator share the reward proportionally. This converts the all-pay auction into a cooperative game where:

Optimal effort (cooperative) > Optimal effort (all-pay auction)

The operator's incentive is to maximize finding probability (not to minimize wasted effort), because sponsors are funding the compute. This aligns incentives toward thoroughness.

Multi-Agent Amplification

Multiple agents sharing context and coordinating coverage means the cooperative effort exceeds what any individual agent would produce — even with unlimited budget. The inter-agent communication protocol creates a multiplier on effort that doesn't exist in any traditional bounty model.
