The ways of voting in current society include: voting by a show of hands, paper ballot, electronic voting, network voting, etc., which have problems of not open, transparent to the public, ballot fraud or changing or randomly changing voting results. <br /> <br /> Taking the current disadvantages of voting technology into account, we will build up an open application called voting chain for voting and voting BlockChain, based on the technological features of BlockChain. We hope the optimized voting technology can make voting more open and transparent, reduce artificial manipulation and ensure that voters can verify their own voting results.
