Science seems to be the world’s first decentralised blockchain. Anyone can start a new parallel chain but for that chain to take over the old one, enough people have to build on top of it rather than building on the old. This is why refuting old claims becomes harder with time.
Interesting, like a platform for ideas under one banner. Some banners have lower critical mass requirements but require boundaries enforced by "enemies" or "others". family -> country -> religion -> science -> "progress" -> humanity -> life
