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.'
QUBITICA is a community of more than 1000 developers, IT companies and investors from over 20 nations who want to work together to advance blockchain technology. This community has developed the QUBITICA infrastructure and since May 2018 it has been working on new projects under the associated brands and websites. Subcontracting is organized within the community. This requires the holding of QBIT, the paticipation shares in QUBITICA and all related projects. A long-term goal of QUBITICA is the development of project-related Smart Contract Solutions. These projects are treated as independent tasks and subprojects advertised individually. This allows us to achieve a flexible pipeline adapted to the needs of the market. The general developments in Blockchain will grow disproportionately, which is why it is the right time to find an intelligent solution to accomplish these tasks. What sets QUBITICA apart from an IT company operating in this field? QUBITICA is not an IT company, but an association of like-minded developers, IT companies and investors. IT projects will be handled under future brands and websites, and QUBITICA will be responsible for exchanging ideas, prioritizing projects and managing the shares in QUBITICA. QUBITICA's QBIT is an ERC-20 token that honors achievements. This honor is also comparable to shares. Developers receive QBIT for the implementation of projects and thus a share in the assets of the platform. A developer becomes, so to speak, a miner of shares through the power of his programming. He can now keep this QBIT, which represents his share of the overall project, or exchange it for Ether or USD / Euro. The mining of QBIT as part of the development of QUBITICA itself is no longer possible. This process is complete. QBIT is also the unit through which investors can acquire shares in the projects. To do this, buy QBIT either from the developers, any holder or via the platform. A purchase on exchanges is of course also possible. For new projects under other brands, the introduction of additional tokens is possible. QBIT holders automatically receive shares in this token upon issue.
