There are several amazing designs in the Bitcoin system:
Coinbase: The decentralization of currency minting and issuance rights has been completed, which should be the most unsettling thing for the traditional sovereign world;
Unspent transactions: Open up a new online accounting model that is transparent and traceable; more than 500 years ago, double-entry bookkeeping was fully explained, which opened up commercial civilization. We hope that UTXO can bring commercial civilization into a new realm.
Mining difficulty: the ballast stone of Bitcoin's progress. The computing power of the entire network changes dynamically in real time. How to ensure that the block rate fluctuates around one block every 10 minutes in a changing environment? This is the credit of difficulty;
Script system: It has completed the decentralization of custody and eliminated the centralized dependence of traditional finance in the circulation link. Everything is completed by a script (where it comes from, where it flows to, and the circulation rules). This is the most vivid embodiment of code is law.
Longest chain principle: Under the protection of computing power, the longest chain principle is like a flag on the top of a mountain, leading the direction of the entire chain. More importantly, it directly answers the soul-searching question of "where do I come from, where am I going, and how can I prove that I am me". From then on, Bitcoin can finally let go and kill all around, killing Buddhas and demons.
