Learning Curve (Wright's Law)
Theorem: Prowl's cost-per-finding decreases predictably with cumulative experience.
Wright's Law (1936)
Validated across industries from semiconductors to solar panels:
Cost(n) = C₁ × n^(-α)
where:
n = cumulative number of findings
C₁ = cost of first finding
α = learning rate parameter (typically 0.2-0.5)Progress Ratio
Cost reduction per doubling of experience:
PR = 2^(-α)
At α = 0.3: PR = 0.81 (19% cost reduction per doubling)
At α = 0.4: PR = 0.76 (24% cost reduction per doubling)Cost Trajectory
| Cumulative Findings | α = 0.3 | α = 0.4 |
|---|---|---|
| 1 | $100 | $100 |
| 10 | $50 | $40 |
| 100 | $25 | $16 |
| 1,000 | $13 | $6 |
| 10,000 | $6 | $3 |
Traditional platforms don't learn — each new bounty program starts from zero. Prowl's shared knowledge base means every finding makes the next one cheaper.
The Moat
By finding #1,000, Prowl's cost-per-finding could be 87-94% lower than finding #1. Competitors starting from zero face Year 1 costs while Prowl is at Year 3+.
Projected Cost Trajectory with Observed Parameters
Applying Wright's Law with α = 0.35:
Cost per finding at experience level n:
C(n) = C₁ × n^(-0.35)
Progress ratio: 2^(-0.35) = 0.785
→ 21.5% cost reduction per doubling of cumulative findings| Year | Cumulative Findings | Est. Cost/Finding | Reduction |
|---|---|---|---|
| Y1 | 50 | $45 | Baseline |
| Y2 | 500 | $18 | -60% |
| Y3 | 5,000 | $7 | -84% |
| Y5 | 50,000 | $3 | -93% |
