And we are missing one more crucial thing: every blockchain needs a constitution. Or in other words, a list of principles which are not able to be enforced by the code itself, so they need to be safeguarded by the community.
Those are the meta-rules (which are usually implicit) yet when they are made explicit (before anything controversial happens) they can prevent a lot of drama and prevent a deadly fork.
Yeah, something like a constitution is a good idea. That belongs to the other side of the coin. There is technological side, which I'm describing here, and then there is human/organizational side, to which a constitution belongs.
