From the Internet of Information to the Internet of Intelligence

Abstract--In the era of the Internet of information, we have gone through layering, cross-layer, and cross-system desi gn paradigms. Recently, the "curse of modeling" and "curse of d i-mensionality" of the cross-system design paradigm have res ulted in the popularity of using artificial intelligence (AI) to op timize the Internet of information. However, many significant rese arch challenges remain to be addressed for the AI approach, inclu ding the lack of high-quality training data due to privacy and resources constraints in this data-driven approach. T o add ress these challenges, we need to take a look at humans' cooperati on in a larger time scale. T o facilitate cooperation in modern h istory, we have built three major technologies: "grid of transporta tion", "grid of energy", and "the Internet of information". In this paper, we argue that the next cooperation paradigm could be the "Internet of intelligence (Intelligence-Net)", where intelligence can be easily obtained like energy and information, enabled by the recent advances in blockchain technology. We present so me recent advances in these areas, and discuss some open issues and challenges that need to be addressed in the future. The Internet has become one of the major foundations for our socioeconomic systems by enabling information exchan ge among people and machines.
