About Feathercoin:

Feathercoin was conceived as a coin that is lighter than light, hence the featherlight name. The coin takes its lightness and suitability for featherlight payments from its faster block processing (one block every minute) and the supply of 336 million coins (of which about 278m are currently in circulation).
The initial blog post from Peter Bushnell about the release of Feathercoin on bitcointalk dates back to April 16th, 2013. Feathercoin, as one of the oldest Altcoins, has proven the test of time. It is also still being actively developed by its founder and a small but strong open-source community contributing to the project.
Feathercoin is an upgraded and customized version of Bitcoin. Users have very easy access to two wallets (FeathercoinCore and Electrum) that work exactly like Bitcoin, but with faster block processing. In addition to these desktop wallets, Feathercoin is supported by various mobile wallets and block explorers.
