> You are still trusting the validators (miners) either way, correct? And how is it more efficient? Who can be a validator (miner) is controlled by the consortium, and therefore the blockchain algorithm doesn't need be to as computationally expensive as bitcoin's proof of work, which is designed to contend with the fact that anyone can be a miner. Instead it can just serve the purpose of enabling a distributed ledger.
