This chapter will first introduce the reader to blockchain technology and the different types of blockchain systems. The underlying principle on how it achieves consensus and guarantees immutability of records in a completely distributed manner is explained. Some use cases where blockchain can address challenging issues in manufacturing environment are given. A particular use case of end-to-end track-and-trace including the manufacturing process on the shop floor is then explained, and showcased in https://youtu.be/rQC_lmt7ZSo by implementing the blockchain-based track-and-trace system with Hyperledger Fabric 2.0. Additional challenges that need to be tackled pertaining to transaction speed and volume are described. To catalyze the adoption, seamless integration of different blockchain systems is needed. This will involve integrating a number of different blockchain protocols. A discussions and recommended considerations for blockchain interoperability, which allow exchange of information/tokens across different systems running different protocols are then given. Finally, this chapter ends with a summary where some of the best practices for a successful blockchain deployment are discussed.
