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.
Crypto.com, the pioneering payments and cryptocurrency platform, seeks to accelerate the world’s transition to cryptocurrency. The MCO Token Sale was conducted in May-June 2017 and raised US$26.7 million. MCO Card is a Visa-branded debit card that draws from a cryptocurrency-funded bank account. Since it’s a Visa card, you can use your MCO Visa card just like you would any other card. The card and bank account are free for holders of cryptocurrency. In order to open an account, you simply sign up, verify your identity, and transfer any of the various accepted cryptocurrencies to your account. At this time, the Visa card is available to customers in Asia. They also have a waitlist for European customers. Customers in the United States does not have access to it at the moment. However, there are plans to change that. Solving the problem of everyday payments has the potential to be huge for cryptocurrency. However, MCO Visa card is not the only project attempting to create crypto-backed debit (or prepaid) cards. Other projects, such as TenX, are working on the same issue. All of these projects run into challenges implementing such cards in a large scale, compliant manner. Crypto.com hopes to crack the code, ultimately getting cryptocurrencies and popular payment methods to play nicely together. Crypto.com was founded in June 2016 in Switzerland and rebranded from Monaco on 6th July 2018. Their first prototype was developed in October of that year. In February of 2017, they were accepted into a Hong Kong Government backed Cyberport incubation program, where they developed their platform until they were ready to launch their token sale in 2017. The sale closed in June with $26.7 million in funding. Their app became available to pre-registered users in August 2017, followed by the official partnership with Visa in October. The team consists of seasoned veterans in the fin-tech space, most of whom have experience in Asia, where Monaco Cards have first been made available. Since MCO Visa cards are backed by cryptocurrency, they don’t have border issues like fiat currencies. As a result, you can use your card anywhere you go. The card will automatically default to the local fiat currency when you make a purchase. The low fees and exchange rates also apply in other countries. Transactions take place at the exact exchange rate that Crypto.com receives as an institutional trader. In contrast, when you use your debit card across borders with most banks, they’ll add an additional percentage to the exchange rate or include a transaction fee. Crypto.com has connections with eight of the top ten international foreign exchange banks to facilitate currency conversion. The MCO Visa card is a compelling option for anyone looking to make everyday purchases with cryptocurrency. It also makes sense for cross-border travelers. However, we can expect the rollout to take a long time and hit a lot of bumps along the way. The financial industry is highly regulated and cryptocurrency-backed payments is a complex issue, even if Crypto.com's solution seems to make it simple and user-friendly.
