Why would anyone spend hashing efforts on those blockchains? And if you "solve" the need for hashing by making the blockchain private within a group of companies, where you expect none of them to attack the blockchains integrity, then your product is no different from having a MySQL database with restricted login
The reason Bitcoin exists is that they're the tokens distributed to make people spend efforts on hashing the blockchain. Without tokens you have no hashing. A blockchain thus cannot exist without a currency (defined as the value of those tokens).
Quark! Quark! Beware the quantum duck!
