Blockchain for Supply Chain Innovation and Transparency: A PRISMA-Based Systematic Review: Enhancing Supply Chains with Blockchain

Blockchain technology is emerging as a revolutionary game changer in supply chain with high promises of addressing the above-mentioned long-standing issues effectively, wherein information transparency and traceability; data security is cause for concern. Through a perspective directed at the roles of blockchain to enhance transparency and enable innovation in various supply chains, this systematic literature review utilizes the Preferred Reporting Items for Systematic Reviews and Meta- Analyses (PRISMA) methodology to investigate recent studies across 20 selected sources. Drawing from broad searches across the Scopus and Web of Science databases, this review is focused on combining main contributions about blockchain applications and its added value for nowadays supply chains. As a result of our work, we have determined that the adoption of blockchain technology allows for improved transparency and data sharing among stakeholders within supply chains in real time securely with more traceability than ever before. The unchangeable ledger of the blockades proved to be quite effective in reducing data asymmetry and preventing information from being manipulated, which is one of the basic fixtures necessary for a more robust supply chain infrastructure. But the literature also uncovers pervasive challenges from technical complexity, interoperability issues to high implementation costs that continue preventing these methods being widely implemented. Despite facing numerous challenges, the implementation of trust bundling on blockchains offers significant opportunities to reduce redundancy and friction within global trade networks. This approach not only facilitates the development of innovative market models that enhance efficiency but also promotes transparency among counterparties across the entire supply chain. This article conducts a systematic literature review that provides useful insights and recommendations for researchers and practitioners seeking to leverage blockchain technology to enhance transparency, strengthen security, and develop innovative services within supply chain operations.
