Tackling Trust and Scalability of the Blockchain-Based Shared Manufacturing Concept

This paper explores the potential of blockchain technology to revolutionize the manufacturing industry through the concept of shared manufacturing. The Blockchain-based Shared Manufacturing concept envisions a decentralized platform that facilitates trustless and efficient collaborations between manufacturers and consumers. While this approach addresses several challenges associated with traditional manufacturing and supply chain management, it also faces issues related to establishing trust among participants and addressing challenges with blockchain scalability, including transaction throughput, privacy, and interoperability. This paper presents an analysis of these challenges and proposes potential solutions, including horizontal scaling via layer 2 solutions and parallel chains, and the use of social graphs, NFTs, and Self-Sovereign Identity for trust and reputation management. By addressing these challenges, the shared manufacturing concept can transform the manufacturing industry, paving the way for a more efficient, transparent, and secure ecosystem.
