Mastercoin / Omni is a digital currency built on top of the Bitcoin blockchain. Its features include the development of a decentralised exchange and the implementation of smart property and savings wallet. The Master Protocol facilitates the creation and trading of smart properties and user currencies as well as other types of smart contracts. Mastercoin enables the Bitcoin eco-system to become more decentralized. The Mastercoin project was launched on 31 July 2013 with a one-month long fundraiser. Those interested in obtaining Mastercoin may send bitcoin to an 'Exodus Address' where the funds collected would be used to fund the development of Mastercoin. Around 500 people invested in Mastercoin sending roughly 5000 bitcoins to the Mastercoin project.
Airbloc Protocol redefines how data is collected, monetized and utilized. Leveraging blockchain technology and token economics, it seeks to facilitate more transparent data flows between data owners, data providers and data consumers. Ultimately, it aims to return data ownership back to data owners, provide applications with tools to collect and monetize data legitimately, and allow data consumers to purchase explicitly consented data with an auditable source of provenance for their business intelligence, research, and targeted marketing purposes.
