I really wonder why u guys still try to solve 'decentralized mining' where u migh start with decent definition and maths measurement for that first.

There is only clear central like fiat or xrp, hyperledger ... even PoS is here imo

Or

Open PoW blockchain where hardest competition and highest degrees of freedom = highest friction does ensure the killing of any too big to fail / monopolist over time.  Even the inner force of a potential monopolist that a central dictated coin has no value will stop him to grow over a specific ownership, wouldn't it?

Increase the degrees of freedom, get rid of artificial limits that are lowering  some miners risks (... bandwidth...)
