Overview

Intro

Helena is a prediction market platform, delivering real-time forecasts on fundamental blockchain events and trends. In contraposition with other prediction market platforms, its behaviour is based on periodic competitions, compensating periodically the best insight providers with economical prices and reputation. This underneath logic is managed through a side-chain infrastructure, enabling :

• High tps on prediction markets

• Trust-less assignation on prices

Basic behaviour

Helena is based on a sidechain infrastructure using Ethereum mainnet to trutlessly compensate providers, and xDai chain to bet on prediction markets. The overall behaviour of the platform can be summarized to 4 simple steps:

1. Bob subscribes to Helena with Dai on Mainnet

2. Bob receives freshly issued xP+ (our internal token) on xDai

3. Bob bets on xDai

4. Bob claim his price at the end of month, receives price on Mainnet

The previously mentioned behaviour is shown in the following picture, and explained on the following sections.
