EarthCoin uses scrypt as a proof of work scheme and is a scrypt coin descendant of Litecoin, Holders can send Earthcoin to anyone in the world - in 10 seconds - without having to worry about banks and borders, it uses a 365 day period & starts with 10,000 coins p/block & it varies in a sine curve with amplitude of 2,000 with a period of one year (like the Earth moving around the Sun). Then a new minimum of 8000 coins per block at about 9 months.
