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.
IOST is building an ultra-high TPS blockchain infrastructure to meet the security and scalability needs of a decentralized economy. Led by a team of proven founders and backed by $40 million from world-class investors, including Sequoia and Matrix, IOST aims to be the underlying architecture for the future of online services. The powerful consensus algorithm “Proof-of-Believability” enables next-gen transaction throughput speeds while ensuring nodes stay compliant, using factors including IOST token balance, reputation-based token balance, network contributions and user behaviors. A faster grade Byzantine Fault Tolerance mechanism, microstate blocks, Atomic Commit protocol and a dynamic sharding protocol (Efficient Distributed Sharding) all ensure transactions are safeguarded, consistent and lightning fast while reducing storage, configuration costs and processing power for validators. Anyone is able to participate in every layer of our system, from using services on our blockchain to running a node and validating transactions. Our rules and code are open for all to see and no preconditions will limit participation. IOST aims to fundamentally disrupt previous methods of business by creating a self-operated, trustless network that maximizes network value for all parties. The project places great emphasis on decentralized and secure ways of storing information. It also provides for Dapps and smart contracts, and anyone who is familiar with blockchain technology knows just how integral these two concepts have become. Adhering to the quintessential egalitarian values of blockchain technology, IOST is creating a censorship-resistant and trustless network that is open to all, using blockchain technology to cut out middlemen and maximize network value for all parties. Terrace Wang, Kimmy Zhong, and Ray Xiao, who are extremely brilliant, have co-founded the project. In addition to these original three, the project has 12 employees and 4 advisors. It is also worth noting that Ryan Bubiski, a co-founder of CodeAcademy and a winner of Times Most Influential People award plays a major role in the advisory board of the project. The team has partnered with about sixteen blockchain and cryptocurrency oriented companies such as Sequoia, Nirvana Capital, and DFund. The project, therefore, has strong investors.'
