We Backtested Our Crypto Ecosystem Score — Here's What Predicted Crash Protection (p < 0.001)

During the 2025–2026 crypto crash, our top-quintile tokens lost 26% while bottom-quintile lost 70%. We didn't cherry-pick this result. We tested across 3 time windows, 355–412 tokens each, with proper out-of-sample methodology. Here's what we found. What Is the Vitality Score? ZARQ rates 15,000+ crypto tokens on a 0–100 "Vitality Score" measuring ecosystem health across 5 weighted dimensions: Ecosystem Gravity (20%) — protocol count, TVL, stablecoin presence on the token's chain(s) Capital Commitment (20%) — TVL retention, yield pool density Coordination Efficiency (15%) — DeFi category diversity, audit coverage Stress Resilience (25%) — NDD stability, crash probability, drawdown behavior Organic Momentum (20%) — TVL trend, price trend, rating trend Grades range from S (≥85, exceptional) through F (<25, minimal). The Backtest: 3 Windows, No Look-Ahead Bias We reconstructed a historical Vitality proxy at 3 past dates using only data available at that time, then measured forward returns:
