🤖 AI Summary
To address the high adoption barrier of deep reinforcement learning (DRL) and the lack of trustworthy mechanisms for collaborative training, this paper proposes the first blockchain-enabled decentralized DRL crowdsourced training framework. The framework integrates a permissioned blockchain (Hyperledger Fabric), federated reinforcement learning, differential privacy, and smart contracts to ensure verifiable training, traceable accountability, and fair reward distribution. Evaluated on CartPole and traffic signal control tasks, it achieves a 23% faster policy convergence compared to conventional federated learning and improves model robustness by 37% under adversarial participant attacks. Its core contributions are: (i) introducing the first DRL crowdsourced training paradigm; (ii) resolving trust bottlenecks and the privacy-utility trade-off in multi-party collaboration; and (iii) providing a novel pathway toward scalable, secure, and production-ready DRL deployment.
