In this paper, we propose that distributed network infrastructure and curation markets based on block chain can solve major problems that have caused public tragedy in traditional content sharing networks. We also illustrate how they can incentivize a distributed content sharing system to self-evolve into a value-generating and mutually-beneficial community ecosystem with a content-sharing platform Innerlight. In this system, anyone who creates valuable things to society will get a reward and the greater the contribution is, the greater the reward is.
