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.

INVERSE is a DeFi based platform that provides an array of smart-contract features with integrated time-based options. Users have the opportunity to speculate on the drop in value of a suite of Defi coins by utilizing the multiple 'tracking vaults' on the platform. XIV, the protocol's native token, is used to unlock these vaults, and then staked within these vaults for no more than 7 days. As their name implies, these vaults track the real-time price movements of select DeFi tokens (i.e. COMP, AAVE, UNI, YFI). After 7 days, if the value of the DeFi asset being tracked has dropped by a certain percentage, the user will gain a significant percentage yield on the amount of XIV held within the tracking vault. If the price of the DeFi asset does not drop in value beyond the predetermined percentage by the end of the 7-day staking period, the user will forfeit a portion of their staked XIV. Rewards will be automatically disbursed to the user’s web3 browser wallet at the end of the 7-day staking period. Ultimately, INVERSE offers users the option to hedge against the volatility of select crypto assets.

Adrealm aims to rebuild the digital advertising ecosystem and cultivate a self-sustaining open ecosystem for all participants to achieve advertising efficiency. Built on ERC-20 standard of the Ethereum platform, Adrealm connects advertisers, service providers, content publishers, developers etc on its decentralized public ledger ensuring privacy and no third-party management of data. Thanks to its three-tier architecture made of an on-chain layer, off-chain layer, and a service layer, speed and efficiency can be guaranteed and the industry pain-points such as fraud, low-quality ads, and data leakage can be overcome. Adrealm relies on a particular consensus mechanism called Proof of Valid Traffic (PoVT) that makes high-quality ads and traffic the fundamental criteria for the operational success of transactions.

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.
