Returns: selfish-mining profitability threshold (Eyal-Sirer), 51%-attack electricity cost estimate, fee-vs-subsidy revenue split, difficulty epoch trajectory (expansion / contraction / neutral), Nash-equilibrium state for honest mining, and current epoch progress. Sourced from mempool.space and CoinGecko — no API key required. Use for miner-incentive analysis, network security assessment, and pre-investment regime detection.","url":"https://the-stall.intuitek.ai/cap/btc-game-theory","method":"GET","headers":{},"bodySchema":{"type":"object","properties":{"properties":{"type":"string"}}},"responseSchema":null,"example":{"request":{"properties":"game_theory_analysis"},"response":{"network":{"block_height":953327,"btc_price_usd":63554,"hash_rate_ehs":932.13},"game_theory":{"subsidy_btc_day":450,"fee_subsidy_ratio":0.008656,"attack_cost_24h_usd":15972957,"fee_revenue_btc_day":3.9294,"selfish_mining_threshold_pct":33.33,"attack_cost_51pct_per_hour_usd":665540,"honest_mining_nash_equilibrium":true},"generated_at":"2026-06-12T05:08:23.568Z","systems_theory":{"security_trend":"Hash rate weakening (-10.48% next retarget).
