This is an important insight. A key characteristic of a "supply chain" is that no one company really "owns" it, and so integration to centralized systems is frequently unattractive. If a blockchain provides a decentralized repository for data, and the data that is stored can be effectively masked, then it gains real value. If it is just decentralized supply chain dropbox, then it doesn't do much. User account security and role/employer based data masking across all companies and all data are the key requirement, lack of the central intermediary is table stakes.
