When it comes to supply chain, companies are always looking for ways to eliminate, or at least control, problems that arise at various stages of the process. The limitations to data-sharing with key parties in the supply chain as well as cybersecurity are examples of common problems. This is where the idea of blockchain comes in. Blockchain is a public ledger that stores all information in one secure and reliable system to which all parties have access. Blockchain provides extensive information of the product’s origin and stages of transport to ensure its quality. Blockchain is transforming the supply chains of all industries, particularly that of aerospace and defense.
