Blockchain has emerged as a prominent and reliable solution that can enable and ensure secure information sharing over wide area networks. In an era of digitalisation, blockchain technology is finding wide applications in multiple fields including implementing traceability in the supply chain. In this direction, this chapter explores its potential application in implementing a blockchain-based traceability system for textile and clothing (T&C) supply chain. It examines the necessity and concept of a traceability system, followed by enlisting advantages of blockchain technology for implementing traceability. Further, a case-based example has been used to explain blockchain application in implementing traceability in T&C supply chain. Finally, it mentions the challenges and limitations of such blockchain-based traceability system that can be addressed through further research.
