‍1. What is 100% Precision?

True 100% precision is not mechanical accuracy, nor complex code, but consistency with natural reality—that is, adherence to the evolutionary law of the irreversibility of time.

The irreversibility of time is the most profound logic of nature. Any system that reverses time is unreal, operable, and modifiable; while a system that follows the irreversibility of time, once in operation, becomes immutable and irreversible—it becomes part of the structure of real nature itself.

2. Dujiangyan and Bitcoin: A Modern Answer to Two Millennia-Old Mysteries

Why has Dujiangyan remained stable for over two thousand years? Why has Bitcoin, since its inception, captivated the world for over a decade without being broken?

Because both embed the design of time irreversibility into man-made systems:

• Dujiangyan follows the flow of water, not relying on closed control, but naturally adjusting through terrain and water momentum, hence achieving natural stability.
• Bitcoin follows time, sealing each second of computational effort into the chain through Proof of Work (PoW). No one can alter its historical timeline.
  

They do not simulate nature—they become part of nature.

3. Film and Art: Precisely Simulating Reality

Why does The Truman Show resonate with so many? Because Truman himself is not an actor; he is a “subject being filmed” living in the real world. This is the pinnacle of precision:

Not imitating reality, but directly capturing it.

Film and art are, in essence, interpretations of real life. But most artworks merely imitate reality. Great films and performances derive their value from how precisely they simulate emotions, behaviors, and context. The higher the precision, the closer to reality, the stronger the empathy.

4. Bitcoin: Humanity’s First 100% Precise Man-Made Creation

The greatness of Bitcoin lies not in being money, but in being the first human-created product that 100% follows the irreversibility of time through machines and algorithms. It does not simulate the real world—it becomes part of the real-world’s time evolution.

This is also why we have yet to create a “more secure” cryptographic system than Bitcoin:

Because we have not yet integrated “time irreversibility” into the mainstream engineering logic of product design.

The essence of security is irreversibility. True security does not depend on “who can change the rules,” but on “once the rules are set in motion, they cannot be reversed.”

5. Future Direction: Building Irreversible Security with Time

Bitcoin is just the beginning. It is humanity’s first dissipative structure product based on time irreversibility. A truly decentralized secure product must be built from the perspective of time, constructing an evolutionary structure, not a pre-defined one.

Most products today remain stuck in dehumanized, standardized logic, yet have not touched the deeper layer of irreversibility. Just like prepackaged meals industrially imitate cooking but can never replicate the authentic taste created by real time and heat.

6. Conclusion: Entering the Age of Precision

What should we learn from Satoshi Nakamoto?

Not to imitate Bitcoin’s mechanism, but to inherit Bitcoin’s spirit: to inject the irreversibility of real-world time into artificial systems, thereby achieving true precision and security.

The future of products will no longer be preset “logically closed systems,” but real structures that evolve with time, self-validate, and cannot be rolled back.

Precision = Following Nature = Following Time Irreversibility

Let us re-understand the path of designing for “natural reality” through Bitcoin and Dujiangyan.
