Seal is a blockchain powered product authentication and services platform which will provide consumers and manufacturers with product trust. Seal enables anyone the ability to confidently, quickly and economically verify the authenticity of any product which is Seal enabled. Seal is the best way for anyone to check if a product is genuine or fake. Seal combines NFC chips, which are embedded into physical products, the Seal app, and the Seal Network to provide a fast, simple, and secure way to provide products authenticity and other services. By facilitating a secure tokenized version of a physical product, Seal allows product-specific services to operate such as transferring ownership, theft prevention, insurance, but also brand activation campaigns and product analytics. Seal lets brands earn money every time their products change owners. For the first time in history, brands can earn money from items sold through the secondhand trade, while simultaneously protecting their markets from counterfeiters. Using the power of the blockchain, authenticity can be checked and ownership can be transferred decades from now, even if the product itself is discontinued, as long as people contribute to the decentralized Seal network. Seal Network is designed for adoption by brands. Its business model allows brands to charge fees for services. For the first time in history, brands can earn money from items sold through the secondhand trade, while simultaneously protecting their markets from counterfeiters. Every time products change hands, the brand earns a fee, turning their products into revenue streams. This offsets the costs of equipping the products with NFC-chips while providing a lucrative revenue stream where brand monetizes their authenticity. By using the power of the blockchain, authenticity can be checked and ownership can be transferred decades from now, even if the product itself is discontinued, as long as people contribute to the decentralized Seal network.
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.
