The major goal of U◦OS project is to design a consensus algorithm with an individual influence score metric, that facilitates effcient score redistribution, motivates users to participate actively in the network development and prevents centralization. Modern blockchain solutions have problems with scalability, security and effciency, and to solve those problems, U◦OS protocol introduces the DPoI (Delegated Proof of Importance) Consensus Algorithm. This consensus algorithm combines the advantages of DPoS and PoI, and delegates validation rights to a limited number of accounts, based not only on the stake value of the protocol members, but also on the their transactional activity, in order to achieve high levels of effciency and scalability within the network.
