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.
Namecoin is a domain name registry service and was the first coin to fork Bitcoin. Similar to registering a .com or .io domain name, you register a .bit domain on the network. This domain is censorship-resistant and impervious to activity tracking. Governments and large corporations control traditional domain name services (DNS) servers. This control is how the Chinese government, for instance, can block websites that go against their beliefs. To prevent this level of censorship, Namecoin uses blockchain technology to distribute its DNS amongst the users on the network. A pseudo-anonymous founder by the name of “Vince” created Namecoin in 2011. Since then, Vince has disappeared, but a core development team has kept the project alive. The project has several developers listed on the official website and benefits from the contributions of numerous anonymous developers as well. Namecoin has been fully functional for a few years, now, and the development team posts updates several times a month. Namecoin was the first cryptocurrency to use Auxiliary Proof of Work (AuxPoW) for its consensus. By using AuxPow, Namecoin and Bitcoin can be mined simultaneously. In this consensus, the child blockchain depends on the proof-of-work of parent blockchain, which means If a new block is created on Bitcoin blockchain, it will also be added to the Namecoin blockchain. NameID is another technology brought by Namecoin. It serves as an open service for securely registering human-readable names in a decentralized way. NameID is a combination between Namecoin and OpenId, where users can easily convert their Namecoin Identities into OpenIDs. This makes NameID a solution to Zooko's triangle, which states that there are three desirable properties (Human-meaningful, Decentralized, and Secure) for name participants in a network protocol and any participant can only inherit two properties at a given time. Namecoin is among some earliest cryptocurrencies. During its existence in the market, it has seen a high volatility on some occasions, which can be attributed to many reasons. Namecoin has been around in the cryptocurrency market much longer than most cryptocurrencies today; however, despite this, it has not gotten much attention until recently. In 2014, it was among the top ten cryptocurrencies by market capitalisation, which is now changed due to the introduction of hundreds of new cryptocurrencies. Namecoin was abandoned by its creator which can be seen as a red flag by many. The project is currently being developed with the support from its community. The current team has been actively taking the project forward and also provides regular updates on social media channels.
