VIZ is a DAC (Decentralized Autonomous Community), this is to say a blockchain system built with Graphene technology (used in BitShares, Steem, partly in EOS). One of its main distinctive features is the principle of equitable participation in the work of the system (fair consensus, fair economy, fair DAC equity management).
Consensus means the Delegated Proof-of-Stake revised. The share of the voter is divided among the witnesses he or she supports. The queue of the witnesses consists of 11 top ones and 10 support ones, which alternate in a round (top, support, top, support, etc.), thus solving the main DPoS problem — that of management centralization.
