Time chain is a new business model that generates value for the time users spend using mobile phones, and returns value to users through the concept of blockchain. The system generates TMC rewards by calculating all user’s Internet behaviors. After obtaining TMC, users can consume in the symbiosis ecology. The attributes of the blockchain will make TMC highly liquid. At the same time, decentralization makes value exchange more efficient, merchants have lower customer acquisition costs, and users directly obtain usage benefits.
