I’m thinking more like an opt-in protocol.
It’s an interesting thought experiment, because every miner would benefit from lower difficulty - small miners and bitaxes especially - but coordination is a hard problem.

GM! Yes coordination will be an issue. I think there are players out there who will not agree / keep increasing hash rate (51 attacks). But to be honest I don’t know the mining business well enough, I started 1-2 yrs ago with a NerdMiner, now with a BitAxe 😂
