Blockchain Reputation

Using blockchain technology allows you to build a network of estimates that can't be edited. The Global system of assessments and interrelations allows you to dynamically display the rating for each network user. The availability of records and common criteria build a rating that will reflect the person's character.

Control your Data

The application stores all the information on the user's device (contact list, list of identifiers and personal data of the network user - name and graphic image).

Native UI

The application have a simple and intuitive interface that allows you to instantly assess and monitoring changes of your reputation in real time.

Private Node

The development of the application lies in the direction of creating a personal private node that allows you to identify your own and other people's identities on the basis of non-dependent algorithms. Using the application will not only assess the surrounding people, but also understand their own place in society and see the possibility of changing it.

What is UPS?

UPS is a digital asset that created to record estimates between users. Evaluation is the transfer of a certain number of reputation tokens to another user's address, some of which are the evaluation criterion (from 0.001 to 0.005 UPS). The Transactions of a larger size are not taken into account when ranking, they are voluntary.

Reputation algorithm

The algorithm for calculating reputation is based on the network graph that public, which allows it to evolve depending on the development of the network. The basic algorithm "Observer" (PreAlpha time) is the arithmetic mean of all user marks. The obtained value of the user's reputation will be guaranteed to be in the range from 1 to 5 (based on the arithmetic mean).
