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.'
Decentraland is an Ethereum-powered virtual reality platform. In this virtual world, you purchase plots of land that you can later traverse, build upon, and monetize. There’s no limit to what you can do. It’s the first digital platform that’s completely owned by its users. Similar to games like Skyrim and Fallout, Decentraland is an all-immersive virtual universe. However, instead of playing on a 2-dimensional screen, you participate in a 3-dimensional world. It seems to be the logical next step before creating full-blown AI-based games in the physical space à la Westworld. Similar groupings on LAND comprise Districts. Districts are basically communities that revolve around a shared theme. For example, there may be a District just for crypto enthusiasts with cryptocurrency apps and services. The Decentraland team is led by Ari Meilich (Project Lead) and Esteban Ordano (Tech Lead). Ordano previously worked at Bitpay as a software engineer and founded Smart Contract Solutions, Inc. Both founders have also worked together in creating Stremium and Bitcore. Decentraland has been around for longer than you may think. The team hit their first development milestone, Stone Age, in June 2015. This was a simple, pixelated grid that allocated pixels to users through a proof-of-work algorithm. Most recently, they held a Terraform Event in which they sold LAND in the new, 3D world. The team has also partnered with district0x, Aragon, and imToken to provide some of their services. MANA is the token used to buy lands in Decentraland. The Blockchain platform can be incorporated in order to buy or sell the various digital assets available in the virtual world. An unclaimed land would have the same market pricing on every exchange possible and precisely the developers are on a hunt for such since as they can build on top of it, and attract lot of popularity. However, one must keep in mind that the land parcels are different from them and each one of them varies according to the various market conditions of that time. Mana can be a great investment and can be bought by trading and with other Bitcoin, Ethereum, or any other prominent cryptocurrency and on some of the most notable cryptocurrency exchanges. Specifically, Binance and Huobi are two of the best cryptocurrency exchanges that one can suggest for trading Mana tokens. The Decentraland coin isn’t a minable cryptocurrency as it is issued on the Ethereum blockchain, unlike Bitcoin and other similar currencies. So users looking to engage in some Decentraland mining will be disappointed. Instead, it was sold during token sales and is now being traded on exchanges.
