One of the first uses of the ICO's documentation for the cryptocurrency project was Mastercoin, which was supported by the community on the Bitcoin Forum. Mastercoin is a meta-protocol on top of blockchain. Bitcoin provides additional features that the basic bitcoin class can not do. The ICO will be available in mid-2013. Mastercoin (MSC) has launched over 5000 Bitcoins (BTCs) at a rate of 100 MSC per BTC and sent to "Exodus addresses" during the ICO period.
