Omni (formerly Mastercoin) is a digital currency and communications protocol built on the bitcoin blockchain. It is one of several efforts to enable complex financial functions in a cryptocurrency.[1] Planned features include the development of a decentralized exchange and the implementation of smart property and savings wallets.[2]

«A common analogy that is used to describe the relation of the Omni Layer to bitcoin is that of HTTP to TCP/IP: HTTP, like the Omni Layer, is the application layer to the more fundamental transport and internet layer of TCP/IP, like bitcoin.»[3]


J. R. Willett published the first draft of the Mastercoin protocol in January 2012 as a white paper, in which he proposed that existing bitcoin protocol “can be used as a protocol layer, on top of which new currency layers with new rules can be built without changing the foundation.”[2]

The Mastercoin project officially launched on July 31, 2013, with a month-long fundraiser in which anyone could buy Mastercoins - the digital tokens that the protocol uses to conduct transactions – by sending bitcoins to a special “Exodus Address”.[2] The idea was that as the platform was being developed, the tokens would become more valuable and investors could sell their Mastercoins to realize a return.[4] A nonprofit organization called the Mastercoin Foundation was formed to handle the funds sent to the address.[2]Despite warnings that Mastercoin might just be an elaborate scam, some 500 people invested,[5] sending a total of about 5000 bitcoins worth about US$500,000 at the time.[6]

As of January 2014, J.R. Willet is employed full-time by the Mastercoin Foundation as "chief architect"[7]

As of February 2014, Mastercoin was the world's seventh largest cryptocurrency by market capitalization according to[8][needs update]

In April 2014, MaidSafe used a crowdsale to raise over $7,000,000 in Mastercoins and bitcoins. The value of the Mastercoins (half the currency) subsequently declined, leaving the total from the sale at $5,500,000.[9][10] In July 2014, MaidSafe COO Nick Lambert was among a number of people joining the Mastercoin board as observers.[11]

In March 2015 Mastercoin efforts were rebranded as Omni.[12] Omni's role in bitcoin ecosystem is declared as being a platform for decentralized protocols like Factom and MaidSafe.[13]
