Anyone that is willing to pay the proposal fee is allowed to add a proposal.
There will be a vetting process, we are not for example going to allow proposals that relate to giving away $CARB or that come with an expectation of creating a completely new service or feature.
Because there is the opportunity to earn $GRAPH from voting, we need to ensure that people do not create new addresses for the purpose of voting only. Therefore, you will have had to register an Avatar Name to be able to vote.
Because your vote will be done by transferring $GRAPH , it is viewable on the blockchain. However, we are also looking into the usage of our blackhole technology to be able to allow for anonymous voting as well.
At this stage we have decided that we will have 3 time periods - 3days, 7days and 14days.
We have given this careful consideration and have decided that you would not be allowed to change or remove your vote once cast. If we were to allow this, then voting manipulation would be possible.
