Mankind made a huge leap forward regarding human organization when it implemented the Constitution. Man was no longer to be ruled by kings and despots, but by a document that stipulated the rule of law. Still, we had the issue of who was going to interpret these laws and who was allowed to add new rules.
Now, we have made another revolutionary leap forward in human organization. We don’t need a third party – kings, governments, courts – to interpret the laws anymore if we have self-executing smart contracts that eliminate the need to trust these third parties. Trust is established through mass collaboration and clever code. On top of that, everyone is free to opt-in, to submit new rules, and to participate in a set of rules. No one is forced to participate. You can always secede. We have had many secessions in the blockchain space. Bitcoin Cash seceded from Bitcoin Core, Ethereum seceded from Ethereum Classic etc. It is therefore a peaceful means to organize human beings.
This is, in my opinion, the fundamental revolution of blockchain: a peaceful trust machine for social agreements and human organization.
