Of course they use a private "blockchain", it's called a database (actually probably multiple databases). All of those numbers and letters just let them identify stuff quickly and efficiently. They don't actually use a blockchain since a centralized database is vastly more efficient than a blockchain. They have no use for a blockchain anyways. M6 = block
