Conventional differential privacy (DP)\u2014with fixed budgets, centralized noise injection, and no auditability\u2014underperforms in distributed settings. We propose Distributed Adaptive Differential Privacy with Blockchain Integration (DADP\u2010BI): each edge node dynamically allocates budgets by data sensitivity\/query frequency, applies Kalman smoothing to local Laplace noise, and uses smart contracts for on\u2010chain audit. Evaluated on the expanded UCI Heart Disease Dataset (920 samples, 14 attributes including high\u2010sensitivity \u201ccholesterol\u201d and \u201cfastingBS\u201d): Privacy leakage dropped by 49.3% (21.7%\u2009\u2192\u200910.8% for \u201ccholesterol\u201d) and 41.4% (15.2%\u2009\u2192\u20098.9% for \u201cage\u201d); Regression errors fell (MSE: 0.38\u2009\u2192\u20090.22, MAE: 0.27\u2009\u2192\u20090.16), and heart disease classification accuracy rose 7.2 percentage points (77.8%\u2009\u2192\u200985.0%); End\u2010to\u2010end runtime and blockchain latency decreased by 18.5%\u201319.8%, with CPU\/memory usage down 31.8%\/26.7%.
