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.
Dentacoin is an Ethereum-based blockchain platform regulated by smart contracts. The platform supports the dental community by building and creating solutions devoted to improving the quality of dental care worldwide. The blockchain gives Dentacoin the power to change the world for the better. Dentacoin develops the dental industry as well as creates market intelligence through a cryptocurrency reward system that inspires participation throughout the community. Dentacoin is the first cryptocurrency that uses a decentralized review platform and transparently rewards patients and dentists who make contributions that benefit the community. The Dentacoin Foundation team strongly believes in building a future healthcare industry that will fall into the hands of the people, resulting in the disruption of the existing industries and the creation of new industries in the short and long term. Dentacoin strives to create a dental industry community by rewarding people -who provide valuable contributions- with crypto currency. Through this reward system, the foundation will see a rise in a currency that will be able to reach a broad market, including a vast number of people who have yet to participate in any cryptocurrency economy. According to Harvard Business Review: “To protect the blockchain vision from political pressure and regulatory interference, blockchain networks rely on a decentralized infrastructure that can't be controlled by any one person or group.' The integration of blockchain and dentistry is an extraordinary concept; one that requires the creation of a community in which transparency and shared responsibility can take place. Looking forward, Dentacoin expects the platform to drastically improve dental health and hygiene habits, thus improving the quality of life for individuals resulting in improved overall health and increased longevity.
