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.
Factom is the first usable blockchain technology to solve real-world business problems by providing an unalterable record-keeping system. By creating a data layer on top of the Bitcoin blockchain, Factom’s distributed ledger technology secures millions of real-time records in the blockchain with a single hash using cryptographic isolation. Businesses and governments alike can use Factom to document their information so that it cannot be modified, deleted or backdated. Factom’s technology decentralizes record keeping by ensuring that the integrity of stored data remains intact, providing complete transparency, while at the same time maintaining user privacy in an increasingly digital world. The Factom project began in 2014 which puts it on the older end of the blockchain spectrum. The team has made steady progress since then. They released the first version of Factom in early 2015 and had their token sale in the middle of that year. In August of 2015, they were accepted into the Plug and Play FinTech accelerator and were chosen as one of Austin’s A-List start-ups in May 2016. Based out of Austin, TX, the core team has multiple members with several years of experience in the blockchain space. Peter Kirby, Factom Co-founder and CEO, and Abhi Dobhal, VP Product Management, previously worked together at CoinTerra, Inc – a producer of ASIC miners for Bitcoin. The price of a Factoid is directly tied to the amount of network usage. As more businesses join the network, it will become more costly to submit Entries which will, in turn, affect the Factoid price. Once the number of Factoids being burned outpaces the 73,000 that are created each month, the currency will become deflationary. This may drive the price up even further.
