Demos consensus mechanism is a new consensus mechanism proposed by Demos development team. Demos is divided into basic chain and extension chain. The basic chain is the POW+POS consensus mechanism, and the expansion chain is Demos consensus mechanism. This consensus mechanism is characterized by wide distribution of nodes, strong work efficiency, and short block time. _The official DEMOS ticker is “DOS” and trades under that name on all the exchanges where it has been listed. The designation “DEMOS” is for CryptoCompare.com only._
