Returning to the Origin: The Human Centered "Satoshi Nakamoto Consensus" is the Core of Cryptocurrency's Solution to Real Problems Summary: Currently, the cryptocurrency industry is overly focused on improving the performance and efficiency of formal blockchain technology, while neglecting its primary value in solving real-world problems. This article argues that the core of cryptocurrency development should return to Satoshi Nakamoto's design philosophy, focusing on solving practical needs through good human-computer interaction and considering usability as an important component of security. Overinvestment in the efficiency improvement of formal technology, if it cannot effectively serve practical applications, will cause the development of cryptocurrency technology to deviate from its rightful track. The Satoshi Nakamoto Consensus, through human-machine collaboration, directly converts real-world resources into digital value, providing a unique example for the connection between cryptocurrency and the real world. Keywords: cryptocurrency, human-computer interaction, real-world problems, formal blockchain technology, performance, efficiency, Satoshi consensus, availability, security, oracle, consensus layer Since the creation of Satoshi Nakamoto, cryptocurrency technology has been dedicated to the potential of disrupting traditional finance and even broader fields. However, in the wave of technological development, a significant trend is to invest a lot of energy and resources into improving the efficiency of formal blockchain technology, such as increasing transaction throughput, reducing transaction costs, optimizing consensus mechanisms, etc. Although these technological advancements are theoretically attractive, this article believes that the primary issue in the development of cryptocurrency is not simply pursuing breakthroughs in performance and efficiency, but should return to its essence of solving real-world problems and use good human-computer interaction as a bridge connecting technology and users. When designing Bitcoin, Satoshi Nakamoto's core goal was to create a decentralized, trustless electronic cash system, which in itself was an attempt to confront real-world financial pain points. He achieved direct control of users' own assets through a sophisticated UTXO model and asymmetric encryption technology, simulating the usability and security of traditional paper currency. Satoshi Nakamoto's design philosophy of "human-computer interaction solves real-world problems, usability is a safety issue" emphasizes that technology must be easy to understand and use in order to truly be accepted by the public and realize its value. The Satoshi Nakamoto Consensus is one of the core innovations in Bitcoin design. It is not just a technical protocol, but also a unique human-computer interaction mode. Miners participate in the operation and value creation of the network by investing real physical resources - electricity and computing power. They 'feel' and 'manipulate' electrical energy for complex calculations, ultimately converting the calculation results (nonce) into the value of Bitcoin. This process is directly recognized by the consensus mechanism of Bitcoin, realizing the direct conversion of real-world resources into digital value and building a system of human-machine interaction and symbiosis. The Bitcoin network is able to directly 'draw' electricity created by humans from the consensus layer and exchange it for BTC with monetary value. On the other hand, current cryptocurrency projects are overly obsessed with formal technological innovation, often neglecting the construction of user experience and practical application scenarios. Ethereum and other platforms, as typical formal blockchain systems, rely on pre-set rules and smart contracts for their operation. Although its ecosystem has been exploring ways to interact with the real world, such as introducing off chain data through oracle machines, these attempts face fundamental challenges. The data provided by the oracle is not native to Ethereum consensus, and its credibility depends on external mechanisms, which is fundamentally different from the direct absorption of real resources by the Bitcoin consensus layer. Only data recognized by the native consensus of blockchain has the highest credibility and significance, while oracle machines (which cannot penetrate public chain consensus) provide simulated sampling of real-world data and cannot truly integrate real data into closed formal systems. Investing too much time and energy into improving the efficiency of formal blockchain technology may lead to deviations in resource allocation. The cryptocurrency field should pay more attention to how to combine blockchain technology with practical needs through innovative human-computer interaction methods. Satoshi Nakamoto's design philosophy emphasizes that 'usability is a security issue'. A complex and difficult to understand system with intricate operations, even if it is technically secure, is difficult for ordinary users to trust and use, and may instead introduce security risks due to user errors. In summary, the future development of cryptocurrencies should no longer prioritize the efficiency improvement of formal blockchain technology. On the contrary, the industry should return to Satoshi Nakamoto's design philosophy and focus on solving real-world problems through innovative human-computer interaction. The model of human-machine collaboration and direct value transformation demonstrated by the consensus of Satoshi Nakamoto provides us with an important insight. Only when cryptocurrency technology can truly serve the actual needs of users conveniently and securely, improve their quality of life, can its value be truly reflected and sustainable prosperity and development be achieved. Investing energy in improving usability, building practical application scenarios, and addressing real-world pain points is the correct direction for cryptocurrency technology to mature and become widely popular. And these ideas are the core of designing the GEB @ BitAgere system.
