This guys explains how boscoin platform works with detailed boscoin review.
Lets say you have an idea and you are looking for public financing. You can receive that financing through boscoin platform and essentially through their congress network.
So you write a proposal and criteria such as how much money you need, how much time it will take, what the milestone are and you send it in the form of trust contract. The trust contract are in human readable lanuguage.
The member of the congress will receive this proposal and they will review it. To be a member of congress you need to hold 40,000 boscoins and run a boscoin node.
You need to be very active in voting or downvoting on proposals.
