The REPU system (abbreviated from English – "reputation") is a revolutionary project that allows you to completely rethink the way social networks are perceived. REPU is a rating and feedback system based on decentralized blockchain technology. Technology allows you to completely replace the system of “likes” with the rating - both for users and for companies. The rating, subsequently, can be used as an assessment tool in various areas of the individual’s life - starting with professional skills, financial stability, and ending with all possible aspects of behavior and interaction with the public.

Quantler is a blockchain for creating, analysing, sharing and running of decentralized structured investment products. Create structured products (such as an ETF) in equities or cryptocurrencies using themes. As there are a lot of the tokenized products being launched (currently over 1 900 available) the structured products for these assets are lacking behind (such as sector-based ETFs). Using Quantler’s blockchain anyone can create structured products (for regular assets such as Equities and cryptocurrencies) and run them on a decentralized network (much like smart contracts). Quantler also allows for regular assets, for this market Quantler’s solution is more flexible and has a lower costs base (targeted for exchanges, family offices and investment managers). The QUANT token’s intrinsic value is dependent on the AUM (asset under management) by the entire network. Quantler is like a Vanguard or BlackRock, but then in the form of a network.

The Constellation protocol implements a horizontally scalable blockchain architecture known as Extended Trust Chain with a peer to peer layer known as a gossip protocol that can be deployed on a mobile device. Constellation approaches smart contracts with a microservice architecture allowing for highly available services to be chained and composed into distributed applications with just an understanding of each microservice’s SLA (service level agreement) and/or type signature. This architecture ensures high transaction throughput, allowing for consumer grade distributed applications to be built on Constellation.
