The hyperledger fabric is pluggable so a consensus algorithm can be chosen to be neither compute or network intensive. Finding a suitable correct algo and verifying its correctness is an interesting task and that is where much of the secret sauce which give this business value could be.
In my opinion this is a good use case for blockchain. I wish them good luck.
