PROT's Master-Node project is to get rid of the excessive resource consumption caused by mining and the power structure that is partial to some mining groups that were considered to be the disadvantages of cryptocurrency in the past. A cryptocurrency platform developed for the purpose. PROT only pays mining compensation to users who have COIN without POW, so anyone who owns PROT can get additional compensation every day. The PROT project has developed from a Master-Node, POS-based cryptocurrency to a more complete mobile platform, and anyone can easily use and own it, becoming a secure cryptocurrency.
