YACoin is robust, secure and reliable open source software that is run by a community of volunteers. Anyone is welcome to add to YACoin, whether by contributing code, or if that's not your thing, translations, how-to's or anything else you can think of to benefit YAC. The official YACoin reposity is @ https://github.com/yacoin/yacoin In addition, there is a development thread that you can:
YACoin was created in May of 2013 and was the first to introduce the N parameter of Scrypt. Check out the Technical Info page for more details. We recently passed block 700,000, and are looking forward to 1,000,000! Many coins come and go well before then. We've just got started! Think YACoin has a small community because we don't have the promotional and marketing juggernauts of some other coins?
