Digitex Futures is a commission-free cryptocurrency futures exchange with a rapid-fire one-click trading ladder and high leverage. Traders can buy and sell perpetual swap futures contracts on Bitcoin against the US Dollar and pay no transaction fees on any trades. The company will be adding extra markets such as Ethereum and Litecoin soon after the mainnet launch on April 27. Commission-free trading is made possible by using its own cryptocurrency, called the DGTX token, as the native currency of the futures exchange. Instead of covering costs by charging transaction fees on trades, Digitex meets the operational costs of running the futures exchange by creating and selling a small number of new DGTX tokens each year.
Solarcoin is a Scrypt based alternative digital currency and its innovation comes from the secondary proof of work reward: the Solar Proof of Work. Green solar energy producers are entitled to receive one SLR for every MWh electricity generated. In order to claim a Solar Proof of Work reward, solar plant owners must submit 3rd party verified energy generation certificates such as a Solar Renewable Energy Certificate (SREC) or equivalent country specific documentation. All Solar Proof Of Work rewards will be stored as transactions in the blockchain. The supply of SLR comprises of the following: - The Mining Pool: 105 million Solarcoins (0.1%) to be publicly mined over the next 40 years. All publicly mined Solarcoins represent historically generated and unclaimed solar electricity. - The Generator Pool: 97.5 billion SolarCoins (99.4%) are currently stored in the OCA non-circulating generation pool account. These will be exchanged for Solar Proof of Work claims of solar electricity generation submitted over the next 40 years at the rate of 1 SLR per MWh of solar energy. - The Genesis Pool: 500 million Solarcoins (0.5%) are stored in the genesis pool account for environmental charities, early volunteers, advisers, builders and maintainers of SolarCoin infrastructure. Genesis pool circulation is capped so that it will never represent more than 5% of total Solarcoin in circulation.
