Using the definition of blockchain as: "A blockchain is a type of distributed ledger technology (DLT) that consists of growing list of records, called blocks, that are securely linked together using cryptography." Then, no, you don't need "blockchain" for that. You don't need it to be distributed. You don't need them to be linked using cryptography. In fact there are good reasons not to use blockchain, such as "I don't want my competitors seeing the exact details of my business transactions". I've heard, "oh but we can fix that with encryption", and then silence when asked "so how are you going to distribute those keys?" etc. Looked into this for large medical supply chain company. Blockchain isn't merely no use, it's actively unfit for purpose.
