PROJECT DESCRIPTION

This is a Cosmos blockchain application. The main idea is to create an alternative job-seeking platform that will be fully decentralized. The platform allows the applicants to have full control over their profiles so nobody can access an applicant’s private information except its professional skills. The businesses which are interested to get access to a full applicant profile must pay a fee to the applicant. The platform states as a game-changer on the market because its model is different from existing platforms that monopolize and control all the information about candidates with no restrictions to sell it to anyone.

PROJECT DESCRIPTION

This is a EOS blockchain-based application (Dapp). The application is a binary option game, where the user can make a short term prediction if a price of a cryptocurrency pair will rise or decline. If the user makes a right prediction then it gets a reward.

The Dapp was implemented the way that any user can join and trade easily even without having a EOS account. All it needs is to sign up using a social account. The DApp supports Facebook, Google, and Telegramm. Every user has a personal account where it can deposit and withdraw cryptocurrencies. Besides the native EOS cryptocurrency, the Dapp supports BTC, LTC, ETH and BNB (Binance Coin).
