"Begin at the beginning," the King said, very gravely, "and go on till you come to the end: then stop."
As mentioned in the beginning, I think that any answer to the question “What have you learned from Bitcoin?” will always be incomplete. The symbiosis of what can be seen as multiple living systems — Bitcoin, the technosphere, and economics — is too intertwined, the topics too numerous, and things are moving too fast to ever be fully understood by a single person.
Even without understanding it fully, and even with all its quirks and seeming shortcomings, Bitcoin undoubtedly works. It keeps producing blocks roughly every ten minutes and does so beautifully. The longer Bitcoin continues to work, the more people will opt-in to use it.
“It’s true that things are beautiful when they work. Art is function.” Giannina Braschi
Bitcoin is a child of the internet. It is growing exponentially, blurring the lines between disciplines. It isn’t clear, for example, where the realm of pure technology ends and where another realm begins. Even though Bitcoin requires computers to function efficiently, computer science is not sufficient to understand it. Bitcoin is not only borderless in regards to its inner workings but also boundaryless in respect to academic disciplines.
Economics, politics, game theory, monetary history, network theory, finance, cryptography, information theory, censorship, law and regulation, human organization, psychology — all these and more are areas of expertise which might help in the quest of understanding how Bitcoin works and what Bitcoin is.
No single invention is responsible for its success. It is the combination of multiple, previously unrelated pieces, glued together by game theoretical incentives, which make up the revolution that is Bitcoin. The beautiful blend of many disciplines is what makes Satoshi a genius.
Like every complex system, Bitcoin has to make tradeoffs in terms of efficiency, cost, security, and many other properties. Just like there is no perfect solution to deriving a square from a circle, any solution to the problems which Bitcoin tries to solve will always be imperfect as well.
“I don’t believe we shall ever have a good money again before we take the thing out of the hands of government, that is, we can’t take it violently out of the hands of government, all we can do is by some sly roundabout way introduce something that they can’t stop.” Friedrich Hayek
Bitcoin is the sly, roundabout way to re-introduce good money to the world. It does so by placing a sovereign individual behind each node, just like Da Vinci tried to solve the intractable problem of squaring a circle by placing the Vitruvian Man in its center. Nodes effectively remove any concept of a center, creating a system which is astonishingly antifragile and extremely hard to shut down. Bitcoin lives, and its heartbeat will probably outlast all of ours.
I hope you have enjoyed these twenty-one lessons. Maybe the most important lesson is that Bitcoin should be examined holistically, from multiple angles, if one would like to have something approximating a complete picture. Just like removing one part from a complex system destroys the whole, examining parts of Bitcoin in isolation seems to taint the understanding of it. If only one person strikes “blockchain” from her vocabulary and replaces it with “a chain of blocks” I will die a happy man.
In any case, my journey continues. I plan to venture further down into the depths of this rabbit hole, and I invite you to tag along for the ride.
