Bihu is a Chinese platform that has recently released a coin-based mechanism for encouraging people to write posts. The design is far from unique; incentivizing online content creation is something that very many people care about. However, as development of these systems moves closer from theory to practice, there are a number of challenges that need to be addressed: self-voting, plutocracy and bribes. These systems are also vulnerable to attack, but unfortunately, these systems can still be used to subsidize wealthy individuals and cartels.
