Launched in Australia, this type of digital coin happens to be employed to conduct deals on the energy market. The alias itself points that way – the cryptocurrency is in use to buy and sell sources and items of electricity. The energy traded within the platform is from renewable sources only, especially when the production reports any surplus amount. Every bit of electricity is tracked from the generator to the point of consumption. It's a Ledger, and everything has to be audible and auditable. The dual-coin system represents another distinctive feature of Power Ledger. The Ethereum-based is known as POWR, and the other coin of the same branch is Sparkz - one of the top crowdfunding enterprises around the globe.
