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.'
Huobi, the third-largest cryptocurrency exchange in the world, recently announced and launched a new currency. The Huobi Token (HT) rewards exchange users for their loyalty with lowered transaction fees while also carrying its own value in tradable pairs against popular currencies. The hope was to bring greater value to Huobi’s millions of users, mostly located in Asian countries. The launch of the Huobi Token follows in the footsteps of other loyalty-building tokens that other exchanges have launched. The first and most successful of these tokens has been Binance Coin (BNB). The creation of BNB secured Binance’s place as the world’s leading exchange. It offered discounted trading fees in exchange for customer loyalty, primarily functioning as a loyalty rewards system. Huobi officially announced its intentions to launch a new token on January 22, 2018. Over the course of 15 days, Huobi would distribute 300 million HT (60% of the total supply) to its pro users who purchased a discounted service package. Each morning, a new batch of HT would become available on a first come, first served basis. Huobi declared this token distribution scheme, “not an ICO,” due to the nature of the offering. Users are buying a specific service package, part of which includes HT that give a discount toward trading fees. The exchange launched the Huobi Token as part of an overall strategy to recover its user base after tightening regulations in China severely restricted cryptocurrency trading. In an interview with CoinDesk, Leon Li, Huobi’s founder, revealed that Chinese rule changes had decimated the trading volume on Huobi by 95% between September 15 and November 1, 2017. The HT token distribution began on January 24 and wrapped up on February 7, 2018. Each day of the distribution, millions of tokens sold out in mere minutes after going on sale. At that point, 300 million HT had been distributed to Huobi Pro members who bought packages. That’s 60% of the total supply currently in public circulation. Another 200 million HT, 40% of the total supply, was set aside. 20% goes toward user rewards and platform operation. The other 20% is vested for four years and constitutes the team reward. Huobi isn’t the first exchange to issue its own token. Binance (BNB), Bibox (BIX), KuCoin (KCS) and Coss (COSS) have all issued their own tokens as well.
