Nxt uses the blockchain to create an entire ecosystem of decentralized features, all of which require the Nxt currency. Instead of modifying the original Bitcoin source code, as many altcoins have done, Nxt developers wrote their own code in Java from scratch. While Nxt is a public blockchain, licenses for private blockchains based on its software are also available for purchase. The developers refer to Nxt as Blockchain 2.0, providing numerous applications beyond simply keeping a public ledger of transactions. Jelurida BV took over the originally anonymously developed Nxt and now own the IP rights. Kristina Kalcheva, co-founder and legal expert of Jelurida, focuses on how to “explore the different open source licensing models and their enforceability in practice.” Currently, the main developer is an anonymous Star Trek fan, going by the name Jean-Luc Picard. While there is still the active development of Nxt, the parent company Jelurida is also working on a Nxt 2.0, known as Ardor, designed specifically to deal with scalability. Ardor will use the same blockchain technology as Nxt, combined with the idea of ‘child chains.’ According to Travin Keith, Nxt foundation Web and Marketing manager, Ardor allows for a “manageable blockchain size, which solves the problem of scalability by separating transactions and data that do not affect security from those that do, and moving all of those that don’t affect security onto child chains.” The core infrastructure of Nxt is complex. This adds risks as compared to the more lean bitcoin, but makes it easier for external services to be built on top of the blockchain. A peer-peer exchange allowing decentralized trading of shares, crypto assets. Since the blockchain is an unalterable public ledger of transactions, the Asset Exchange provides a trading record for items other than Nxt. To do this, Nxt allows the designation or ''coloring'' of a particular coin, which builds a bridge from the virtual crypto-currency world to the physical world. The ''colored coin'' can represent property, stocks/bonds, commodities, or even concepts. Arbitrary Messages enable the sending of encrypted or plain text, which can also function to send and store up to 1000 bytes of data permanently, or 42 kilobytes of data for a limited amount of time. As a result, it can be used to build file-sharing services, decentralized applications, and higher-level Nxt services. Nxt had no mining phase, all initial units were released to 73 people through a one-time fundraiser via bitcoins, after the announcement of the NXT project in the bitcointalk-forums by BCnext. Combine this with a PoS approach, and you have a situation where the big guys run the table. At one point, the Nxt community had a very public spat with Bitcoin developer Jeff Garzik. Garzik took issue with the Nxt marketing approach, its anonymous developers, and their responses to constructive criticism. Nxt responded to some of these claims, of course, but it remains one of the more controversial moments in its history. Another key problem the Nxt network ran into (like so many others) was blockchain bloat. Nodes get weighed down by the onerous task of having to store every transaction on the Nxt blockchain. This was one reason (among others) why Ardor/Ignis came into existence.'
Emercoin (EMC) is an open-source cryptocurrency which originated from Bitcoin, Peercoin and Namecoin. Other than being a cryptocurrency, it is also a platform for secure distributed blockchain business services. The EMC coin is used for accessing the blockchain-based services provided by Emercoin. Emercoin inherits the reliability and security of Bitcoin, while at the same time adding more features to its own blockchain by leveraging several innovative technologies. The Emercoin blockchain has been specially designed to provide businesses with the secure blockchain services and also allow them to create their own decentralized apps. Emercoin was founded in the year 2013 by Eugene Shumilov who also serves as the chief executive officer of Emercoin. The Emercoin team also consists chief technical officer Oleg Khovayko, a cryptocurrency & financial expert and Stan Polozov a Blockchain Implementation Specialist. Emercoin is also backed by a decentralized team of nine advisors from across the world. Emercoin has been in the market since 2014, and its past trend in the cryptocurrency market shows that it has followed a steady and stable growth. Emercoin has scored many partnerships. Two of its major partners are Coca Cola and Microsoft. Some other partners are RedHat, LLoyd’s, Bitfury, Aspanta, Deloitte, Authorizers, Foundico, Anteko, etc. Emercoin has also been featured on some prominent media platforms such as Forbes, Digital Trends, Engadget, The Business Times, Aljazeera, Gadgets Now and others. With the sheer variety of services that the Emercoin platform makes available to its users, it would not be surprising to see this currency be viewed as a lucrative investment option by many novice as well as experienced investors in the near future. With the currency’s value currently hitting new highs, it can be said that many people are now beginning to see the true power and potential of this emerging blockchain. However, as is the case with all crypto assets, past performance should not be used to predict the future value of EMC.
