Supply chains are challenged with providing transparency and trust among participants and stakeholders and ensuring an efficient operation. However, some of these challenges are difficult to resolve because the records of a supply chain can be altered by its participants. The emergence of blockchain technology has been identified as a promising solution to resolve these challenges. Blockchain is an immutable distributed ledger. Here, we introduce blockchain and survey different blockchain frameworks that have been recently proposed to address some of the supply chain challenges. We describe the operation of these blockchain frameworks and their components. We identify the objectives and motivation in each of the surveyed use cases and highlight the advantages and disadvantages of each adopted framework by different industries. We analyze how the reported blockchain frameworks address supply chain challenges. We present a comparative summary of existing literature on blockchain for supply chain. We also summarize the properties of a blockchain framework for its successful adoption in future supply chains and discuss several challenges and opportunities that remain for future research.
