We live in an advanced knowledge based information society. Whole society has been affected by the power of knowledge and, rapidly changing economic structure. Knowledge and information are no longer recognized as personal culture or qualification but as asset in itself. Unlike the spot market, there’s no distribution system in knowledge market in comparison to the growth of the value. Current knowledge market can’t reward suppliers for their information. As a result, people neglect or waste knowledge property. To solve these problems, blockchain system, AI and big data are needed. Blockchain can provide the high-quality information by preventing users from manipulating and proper reward to the information providers. Users and provider will be properly connected by AI and big data. The IAN project is a platform that connects users and providers directly to trade knowledge with IAN Coin as a payment for cultural content.
