Blockchain-Based Distributed Machine Learning Model Governance

Abstract

This paper proposes a novel approach to governing distributed machine learning (ML) models using blockchain technology. The core claim is to establish a decentralized platform for managing ML model versions, controlling access permissions, and distributing rewards, all while enhancing transparency and trust. The proposed mechanism leverages blockchain's immutability and smart contract capabilities to record model metadata, training data provenance, and participant information. This allows for automated execution of governance rules, mitigating issues associated with traditional, centralized ML model management, such as single points of failure, biased data handling, and lack of transparency. The system aims to foster a more equitable and trustworthy environment for collaborative ML development and deployment. Key performance metrics, such as model accuracy, data integrity, and participant engagement, are inherently tracked and verifiable through the blockchain.
