POA Network has created a unique model where network operation decisions are voted upon by private nodes designated by a single individual. This individual initializes the network and gives voting power to the individuals running the nodes. This structure appears similar to the classic board of directors appointment for companies that are publicly traded, knowing this it's evident how scalable this technology will be as it provides confidence to stakeholders in control.
Collusion of validators (nodes) is a risk which is only somewhat mitigated by the use of a non-affiliation agreement, the master of ceremony must effectively make the best decision based on their own discretion when the initial keys are distributed, mistakes could be costly in the long run. Securing a network with more trusted validators is optimal for the network but does not implicitly mean an increase in the price of the currency will happen, such assumptions are contrary to basic economics of supply and demand. While we don't expect this to be the next Ethereum, we still see a lot of potential and value in the POA Network. Compared to the majority of ICOs we have looked at, we do believe it is worthy of supporting if you understand and support their consensus model.
