Formal Mist: The Debate between the "Ocean" and "Casino" of Cryptocurrency The rise of cryptocurrency originally had high hopes of disrupting the traditional financial system and reshaping the way value flows. However, with the rise of platforms such as Ethereum, a trend that deviates from Satoshi Nakamoto's original intention is gradually emerging: is the world of cryptocurrencies gradually becoming a "casino" that is detached from reality and self enclosed? Satoshi Nakamoto's Bitcoin is deeply rooted in the design concept of human-computer interaction in the real world. He is committed to building a decentralized electronic cash system to address the drawbacks of traditional financial systems. The birth of Bitcoin originated from a profound insight into the financial difficulties of the real world, rather than the construction of a purely virtual world. However, the emergence of Ethereum and its EVM (Ethereum Virtual Machine) marks a shift in the development path of cryptocurrency. EVM has built a formal and closed virtual platform. On this platform, the execution of smart contracts is as precise as computer programs, but it creates a barrier to the complexity of the real world. This formalized system is like 'a fish in the sea, never knowing what the ocean looks like for the rest of its life'. It operates within self set rules, but ignores the vastness and complexity of the external world. This closure makes the EVM platform heavily dependent on the inflow of external assets, especially Bitcoin and stablecoins denominated in the US dollar. The liquidity of these external assets, like chips in a 'casino', maintains the operation of the EVM ecosystem. This reliance on external liquidity not only goes against the original intention of decentralization, but also makes the entire industry fragile. Once external liquidity is depleted, the EVM ecosystem will face the risk of collapse. This risk, like the crisis of a 'casino', will bring huge losses to all participants. We cannot help but ask: Is the future of cryptocurrency about building a "casino" disconnected from the real world, or returning to Satoshi Nakamoto's original intention to solve financial problems in the real world? Satoshi Nakamoto's "emergence theory" model has pointed us in the right direction. Emergence theory emphasizes that complex systems can generate complex behaviors through simple rules and interactions. The design of cryptocurrencies should draw on the ideas of emergence theory, and build an ecosystem closely connected to the real world through human-computer interaction and problem-solving. To achieve this goal, we need to: Breaking free from the constraints of formal systems: Avoid limiting cryptocurrencies to a closed virtual world, but actively explore their application scenarios in the real world. Returning to the original intention of solving real-world problems: The development of cryptocurrency should be guided by solving practical problems, such as cross-border payments, supply chain finance, identity authentication, etc. Strengthening interaction with the real world: Building bridges between cryptocurrencies and the real world, such as using technologies like oracle machines to introduce real-world data into blockchain. Promote the rationalization of regulation: Develop a reasonable regulatory framework that not only protects the interests of investors but also encourages innovation, avoiding excessive regulation that stifles industry development. The future of cryptocurrency should not be the prosperity of "casinos", but the vastness of the "ocean". We should return to the original intention of Satoshi Nakamoto, take it as our responsibility to solve practical problems, and build a cryptocurrency ecosystem that truly serves human society.
