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.'
BITKAN as an App serving cryptocurrency users and integrating market, information, mining monitoring and wallet, it provides four language versions, namely Chinese, English, Russian and Japanese. Now it has more than 5 million users from 170 countries around the world. BITKAN provides quotations and candlestick charts of more than 2,200 kinds of cryptocurrencies from more than 50 major cryptocurrency exchanges around the world.

BITKAN provides wallet services for digital asset transfer, such as BTC, BCH, DASH, ETH, SAFE, and it has provided stable and secure wallet service for the assets of 170,000 users. The team will launch the first blockchain-concentrated community around the blockchain industry based on the BITKAN platform: K Site. The community will encourage users to produce high-quality contents, and users can get profits in the form of cryptocurrencies by publishing high-quality contents. The communities created by users in the community will be presented in the form of 'K Site'. The creators can set up the 'K Site' to pay for admission or join for free. By composing high-quality contents, it can attract other users to join in and form their own 'K Sites'. Users having joined in can read the contents of the 'circle' or post their own content in the 'circle'. On the other hand, users can also set a certain content for paid reading, the more people who read, the greater the income. Users can also reward the content to encourage the author to continue to compose more and better content. KAN will be used to pay for the platform services of BITKAN. If a user keeps sufficient amount of KAN will enjoy a certain percentage discount for service fees, and service fees will be deducted from KAN. The main project team comes from BITKAN, which currently provides price monitoring, news and information, mining monitoring, wallet and other services for cryptocurrencies. Users can store cryptocurrencies simply, conveniently and safely through the BITKAN app. At the same time, they can check the market price of cryptocurrencies of major exchanges in real time, get timely and fresh industry information at home and abroad, and set up price reminders by BITKAN app. And it has real-time mining monitoring, which allows you to master the running condition of the mining machine whenever and wherever possible. The token is called 'KAN'. A strict limit of 10 billion KAN will be issued, and will never be increased. KAN will be issued according to the Ethereum ERC 20 standard. KAN's profit comes mainly from the payment fees, exchange fees and membership service fees from the BITKAN platform. BITKAN is already online. The team is currently developing the 'K Site' feature which is a decentralized crytocurrency-concentrated & content payment community. KAN will be online as the same time as the 'K Site' feature, which is scheduled in May 2018.
