🧵 Bitcoin is not just a currency, it is a "philosophical machine" - an organic computer composed of Turing machines, oracle machines, and ordinal logic. It integrates time, consensus, and trust into an irreversible evolutionary system. This article takes you through the deep structure behind Bitcoin. 👇 2/ Our usual understanding of 'Bitcoin' only stays at the level of currency or blockchain technology. But fundamentally, it is a concretization of computational philosophy. It was not born for programmability, but built to solve the 'undecidable problem'. 3/ Traditional computers are based on Turing machines and process computable Shannon information; The Bitcoin system, on the other hand, is embedded with three levels: Turing machine system (computable layer) Oracle Machine System (Judgment and Fork Layer) Ordinal logic system (irreversible time system) 4/ Type 1 system: Turing machine (TX layer) It performs deterministic transactions such as UTXO checks, signature verification, etc. This is the 'formal system' of Bitcoin, which handles logically closed computations but cannot determine self referential problems such as' double spending '. 5/ Type 2 System: Oracle Turing Machine (Block Layer) When the system encounters an undecidable double spending problem (such as two transactions spending the same coin), it must resort to "external arbitration": who packages first, who is valid. This ruling is a 'divine act' and also the root of the fork. 6/ The third type of system: ordinal logic system (time layer) Satoshi Nakamoto constructed an irreversible time system using Proof of Work (PoW), which is the ultimate arbiter of Bitcoin. There is no subjective arbitration, only 'who is proven first'. 7/ These three make up the "organic computing structure" of Bitcoin: Turing machine processing forms computable transactions The oracle mechanism deals with undecidable self referential problems Ordinal logic turns oracle judgments into irreversible time trajectories 8/ Why is Bitcoin designed to be so secure? Because it uses time as the foundation of trust, embedding the entire system into an irreversible thermodynamic dissipative structure. PoW is not about consuming energy, but about creating irreversible history. 9/ This system has achieved three major conversions: Transforming computability limitations into trust logic Transform undecidable problems into a consensus across the entire network Transform the local fork into a global evolutionary trajectory 10/ Bitcoin is not a part of Web3, nor is it a prototype for smart contract platforms. It is another dimension of 'philosophical computational entity': It doesn't care about whether you can program, but about whether your affairs can overcome uncertainty and obtain conclusive time judgments. 11/ This also explains why Bitcoin must be Turing incomplete: Because it does not solve problems within formal systems, but rather builds arbitration mechanisms and evolution time outside of formal systems. 'Integrity' comes from the overall system, not local code. 12/ Bitcoin is: Decentralized time machine Non repeatable arbiter Extracting dissipative structures of order from chaos Meta logical systems outside of formal systems 13/ Understanding Bitcoin is not about understanding its code, but about understanding how it becomes an automated philosophical machine. It is the first engineering practice in history to merge the ideas of G ö del, Turing, and Prigogin into a runnable system. 14/ This is the true breakthrough of Bitcoin: It's not a currency revolution or a blockchain revolution, but a revolution in computational philosophy. It provides a paradigm for future trust systems, cognitive systems, and order systems. 15/Done The ultimate significance of Bitcoin is that it has become the first system in the real world capable of handling undecidable problems - using irreversible time as trust, physical evolution as arbitration, and logical incompleteness as the source of order. ⛓️ Welcome to follow more exploration of deep computing philosophy.
