To address performance degradation caused by non-IID data and privacy leakage and trust bottlenecks arising from centralized architectures in federated deep learning (FDL), this paper proposes a blockchain-empowered decentralized FDL framework. The framework integrates zero-knowledge proofs, Practical Byzantine Fault Tolerance (PBFT) consensus, and differential privacy, deploying lightweight smart contracts on an Ethereum sidechain to ensure verifiable model updates, anonymous participant identities, and robust Byzantine node detection and removal. Evaluated on an industrial IoT dataset, the framework achieves 98.2% model accuracy, reduces communication overhead by 37%, attains >99.4% success rate against Byzantine attacks, and complies with GDPR requirements. This work is the first to deeply integrate verifiable computation with decentralized consensus in FDL systems, establishing a novel paradigm for secure, trustworthy, and efficient collaborative modeling in intelligent enterprise scenarios.
