The New Mexican Republic uses a block chain (BitCoin derived) based voting system called BlockVOTE. Key elements of the system are that each citizen is given a number of votes per year. The number of votes per citizen is allotted by perceived need, allowing the underprivileged to be given a greater voice when needed. Voting occurs several times during the year as determined by issues facing the community. It is normal and legal to sell your vote coins as you see fit.
This is considered a better method of redistributing wealth than progressive taxation.
