Any bitcoin improvement proposal must get 90% approval from miners to 'pass'

I think the threshold is 90%

The blcokchain/Roger Ver war in 2017 was interesting because miners wanted bigger blocks but nodes defeated miners

update: when did Satoshi disappear? I believe his last post on bitcoin talk forum was December 2011, maybe it was Dec 2010. He disappeared around the same time there was a lot of heat on WikiLeaks and Julian Assange
