Sierracoin is the first foundation to develop mining using solar energy. You can pay for mining other crypto currency using electricity and at the same time convert the amount of energy spent into Sierra. Now the cost of bitcoin and other crypto-currencies using the PoW algorithm is determined by the price of electricity spent for extraction of one unit + an added market value. We are going to include our own mining algorithm within the next 1 year, at 200,000 block a hardfork network will be run with the inclusion of solar mining. The first customers will be able to rent solar batteries from our foundation, you can receive crypto currency at your wallet, we will also develop a personal web wallet, with the possibility of PoS mining and the accumulation of sierracoin.
