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.
Power Ledger (POWR) is an Australian blockchain-based cryptocurrency and energy trading platform that allows for decentralized selling and buying of renewable energy. The platform provides consumers with access to a variety of energy markets around the globe and is meant to be scalable to various energy infrastructures and regulations. The market is based on a dual-token ecosystem operating on two blockchain layers, POWR and Sparkz. POWR tokens allow consumers and hosts providing energy to interface with the ecosystem and are protected through Smart Bond technology. POWR tokens can be converted into Sparkz tokens, which can be used for frictionless transactions in the energy exchange market. The initial coin offering for POWR tokens became the largest crowd funding project in Australia and the 14th highest in the world. Power Ledger’s team has immense expertise in both blockchain and electricity markets. They’re comprised of six Board of Directors in addition to over ten full time-team members. Power Leger’s five co-founders make up five of the six Board of Director seats of the company. The sixth board seat belongs to venture capitalist Bill Tai. Receiving his MBA from Harvard, Yai is a world-renowned venture capitalist. Tai’s experience is quite extensive; he is currently the Chairman of Treasure Data and also a Board Member of Bitfury and Boxer. Power Ledger’s POWR Presale sold out in just three days and raised over thirteen million dollars (AUD) in exchange for 190,000,000 tokens. After the presale, Power Ledger held an ICO to sell the remaining 160,000,000 POWR tokens allocated to Token Generation Event. After both rounds, funds raised totaled thirty-four million dollars (AUD). In addition to money raised from its presale and ICO, the Australian Government also awarded Power ledger a grant for 8 million dollars (AUD) to develop its technology and concept further. (Australia has one of the highest costs of electricity in the world and thus has a large stake in the overall success the company). Power Ledger provides a blockchain-based marketplace that can truly change the world. Taking power away from large energy companies, Power Ledger gives local communities the ability to sell their excess solar power to neighbors. Power Ledger has created an energy distribution and tracking platform that allows consumers buy carbonless, sustainable energy at lower prices than what’s offered by traditional electric companies. Power Ledger has plans to expand its operations to three continents worldwide and has amassed an army of powerful strategic partners to help achieve its goals. With the planned release of multiple applications for its platform in the immediate future, the project has positioned itself to disrupt multiple energy markets throughout the world creating a bright future for all participants involved in this green revolution.
