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.

KardiaChain is the blockchain of blockchains. A scalable and interoperable blockchain platform for decentralized applications. Our Vision: We believe Blockchain can create equal opportunities for people, a world where people have access to opportunity to invest, to start a business, to work and to be socially mobile. Our technology empowers mass adoption, expand use-cases and lay foundation of the blockchain ecosystem. We are building a blockchain platform for decentralised applications helping to create a blockchain ecosystem that allows for scaling and connecting disparate blockchains. Our Core Technology is: - Dual Node - Elastic Sharding With Incentive Mechanism (ESWIM) - Kardia Smart Contract Markup Language (KSML) Our Use cases are: - Supply Chain Management - Fully Decentralised Cross-chain Exchange - Smart City

Our Armacoin GZM coin is specially designed for advertising companies, various media, various greetings registered on the basis of blockchain. Each new message will not be overwritten by the previous one, but will be supplemented. These advertisers can be quite a lot and each of them will receive a payment for their advertising message. The cost of this one message will be 1 GZM. A specific function and variable were added in this coin. The function «Set-Messange» and the global variable «Messange» that is permanently stored in the blockchain. The «SetMessange» function adds a line to the «Messange» function and the 1 GZM is removed from the account of the one who calls this function and transfers this 1 GZM to the advertiser's account. This coin is like a prototype of a Billboard, where the owners of this token, that is, advertisers, can place a message in the contract line for only 1 GZM. The advertiser can place this message on the billboards in different cities, on websites and all visitors will see what is specified in the global parameter of the messange. This coin was created on the ERC-20 contract. The total number of issued and coins for mining does not exceeds 1 billion. The mining of this coin is also unique because it allows to generate GZM tokens with low power renewable energy. This leaves most of the green energy to use for the network, while the miner can use the opportunity to acquire new tokens. We are also developing applications for this smart contract and will give the opportunity to mine these tokens using renewable energy sources, various gadgets with installed pedometers apps, electric vehicles, fitness bracelets and much more. Everything will be done for environmentally friendly and safe mining, as well as for the stimulation of a healthy lifestyle of the people living on our planet. We will encourage everyone who cares about the purity and ecology of our planet.

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.

Tachyon Protocol is a decentralized internet protocol built on the V SYSTEMS blockchain that aims to create a trusted, stable, fast and reliable decentralized information network. By implementing techniques from DHT, blockchain, UDP and encryption, Tachyon Protocol is committed to building the next generation TCP/IP that can provide a self-sufficient internet environment with high security, untraceability and maximum network speed. As the first application running on V SYSTEMS, Tachyon is powered by X-VPN, which has proven technologies and 50 million existing global users to bring blockchain technology into the mainstream. IPX token is the native cryptocurrency of the Tachyon network that resides on the V SYSTEMS blockchain. The token provides easy and affordable means of sharing spare bandwidth among users, promotes positive development of the network, solves major problems with the organization of the decentralized network and serves as proxy valuation of the overall system.
