The Rise of Blockchain in Supply Chain Management
Blockchain, the revolutionary distributed ledger technology, has gained significant attention in the world of supply chain management. As globalization and technological advancements continue to transform industries, supply chains have grown increasingly complex, with multiple stakeholders and factors involved. Traditional supply chain systems have struggled to provide effective and reliable traceability solutions, especially as the demand for transparency and accountability in the supply chain has escalated.
Blockchain technology, with its inherent features of immutability and transparency, has emerged as a promising solution to address the challenges faced by modern supply chains. By creating a dependable and secure system for tracking products across the entire supply chain, blockchain ensures complete control over traceability from the origin to the final consumer.
This comprehensive systematic review delves into the evolving landscape of blockchain-based supply chain frameworks, exploring the capability of this innovative technology to revolutionize the industry. The research examines the current state of blockchain-based supply chain solutions, identifies areas for improvement, and investigates the potential synergies between blockchain and other emerging technologies of Industry 4.0 and Web 3.0.
Understanding the Technological Landscape
Industry 4.0: The Convergence of Physical and Digital Worlds
The first three industrial revolutions were marked by the use of steam engines, electronics, and information technology, respectively, leading to the mechanization, mass manufacturing, and automation of production. Industry 4.0, or the Fourth Industrial Revolution, signifies a new era characterized by the convergence of the physical and digital worlds, known as Cyber-Physical Systems (CPS).
CPS enable the interaction between digital infrastructure and physical objects, making information and services concurrently accessible for various purposes. Industry 4.0 technologies encompass a wide range of innovations, including but not limited to additive manufacturing (3D Printing), artificial intelligence (AI), Global Positioning System (GPS), big data and analytics (BDA), Radio Frequency Identification (RFID), blockchain (BC), cloud computing (CC), Internet of Things (IoT), simulation, augmented reality, robotics, and unmanned vehicles.
Web 3.0: The Decentralized Future of the Internet
The convergence of these technologies is facilitated by numerous internet-based innovations, collectively referred to as Web 3.0. This includes artificial intelligence (AI), machine learning (ML), big data, decentralized ledger technology (DLT), metaverse, decentralized applications (dApps), Semantic Web, edge computing, and non-fungible tokens (NFTs).
Web 3.0 aims to enhance the security and privacy of the decentralized internet through the use of blockchain technology. This contrasts with the current Web 2.0, which is regulated by a few large tech companies, offering a more user-centric, secure, and transparent experience. Web 3.0 applications, known as decentralized apps (DApps), function on decentralized networks made up of peer-to-peer nodes or blockchains, eliminating centralized decision-makers and regional restrictions.
