Bitcoin is two things:

• digital, yet absolutely scarce, property (for some, bitcoin is also a form of money, though this claim would require to address Mises' regression theorem): in this case, it's "bitcoin", with lower case "b";

• A decentralized, trustless, peer-to-peer, open-source, censorship-resistant financial network: "Bitcoin" with an uppercase "B".

In the Bitcoin protocol are codified:

• the first law of monetary economics (any quantity of money is optimal for any economy as long as its quantity is fixed and sufficiently divisible): the bitcoin supply is fixed (21 mln btc). Therefore the entire marginal, subjective value theory (from which the previous law derives) is codified into Bitcoin.

• the principle of equality before the law, on which the entire structure of non-arbitrary law (the non-aggression principle), and therefore freedom, rest: no node or miner is privileged.
