It's a huge design flaw though. The original intention of the blockchain in Bitcoin was to make it so it was decentralized...except the increase in computational difficulty, the winner-takes-all payouts, and the electrical cost, of course means that eventually the only people running the blockchain are large centralized organizations.

At which point one can wonder, why bother being distributed when we're still ultimately invoking trust in several groups? Couldn't we do this a lot more simply and efficiently by just having everyone delegate a private key signing operation to these groups so that it's just based on maintaining consensus, rather then burning CPU time on computationally hard problems?
