The Bitcoin network is an emergent decentralized monetary institution that exists through the interplay of [full nodes](https://messari.io/resource/node), [miners](https://messari.io/resource/mining), and developers. Furthermore, it is set by a social contract created and opted into by the network’s users, which is hardened through [game theory](https://messari.io/c/resource/game-theory) and [cryptography](https://messari.io/resource/cryptography).",
