From Physical World to Cyberspace to Cypherspace: Understanding the Essence of Blockchain Technology
Blockchain has become a buzzword lately. However, what the real problems that blockchain technology can essentially solve remains not crispy clear. In this research presentation, we present a framework that distinguishes the problem space that blockchain technology aims to address from other problem spaces. It is argued that the problem space that blockchain technology is in is the Cypherspace, which is different from the physical space where we live our lives daily, and the cyberspace where we access, share and process data to support or enhance our daily lives. Within the Cypherspace, we not only want to mirror our physical world, but also improve our physical world; and most importantly, we not only want to uniquely identify ourselves or events or objects or entities, but also want to automate many processes that are critical to our daily lives, such as guaranteed contract execution, C2B ecommerce and many DAO-oriented activities. The differences between the 3 spaces are discussed, and examples are discussed. The ideal and intended interfaces between the spaces are discussed. The interfaces are extremely essential for the information exchange between the spaces between physical space and Cypherspace for the smart contracts to be executed. Some general templates with sample code are proposed to help the design of the interfaces for the Cypherspace. And the re-design capability of the blockchain technology in regulating or perfecting some imperfect phenomenon in the physical world is discussed with recent research result about overcoming digital divide and China’s poverty elimination issues.DAO and smart contract structures are discussed to define the essentials of applications that blockchain technology is designed to tackle. A prototype system is also proposed to create common interface standards for the Cypherspace to facilitate the more widespread applications of blockchain technologies.
