ARK provides users, developers, and startups with innovative blockchain technologies. They aim to create an entire ecosystem of linked chains and a virtual spiderweb of endless use-cases that make ARK highly flexible, adaptable, and scalable. ARK is a secure platform designed for mass adoption and will deliver the services that consumers want and developers need. It is fast, decentralized, scalable, collaborative, bridging and open-source. The ARK Desktop Wallet is natively built for all major Operating Systems. ARK wallets connect to fully synced network peers removing the need to download the full blockchain. ARK operates using a Delegated Proof-of-Stake (DPoS) consensus algorithm. Unlike Bitcoin, in which miners with expensive rigs secure network transactions, the ARK network is secured by delegates. There are hundreds of potential delegates, but token holders in the ARK ecosystem continuously vote on who actually gets to be an active, forging delegate. Only 51 delegates make the cut. As a token holder, you’re only allowed to vote for one delegate at a time. The fee to vote/unvote is just 1 ARK, so it’s advantageous to at least vote once for a delegate you support. The more ARK tokens you own, the more powerful your vote. ARK was launched in February of this year by 27 members spread across the world. With team members located everywhere from California to Bulgaria – the ARK Crew is truly decentralized. The team currently consists of 15 core members. The ARK infrastructure is modeled heavily on that of three older projects: Bitshares, Crypti, and Lisk. In fact, some of the ARK developers were previously developers on some of those projects. Francois-Xavier (FX) Thoorens, the CTO, was a core developer at Lisk in 2016. Ark Community A diverse group of people and skill sets, including Full Stack and Web Developers, Network Engineers, Hardware Experts, Money Managers, Musicians, Traders, Social Media Promoters, and Business Owners, uniting to realize a vision shared by 30 members of the ARK Crew. All passionately devoted to collaboration and the development of the ARK ecosystem and community. Ark Token Secured by a cryptographic blockchain network similar to Lisk and Crypti, running on a Delegated Proof of Stake Consensus Algorithm developed by Bitshares. ARK DPoS provides a newly adapted voting system and incorporates many improvements over previous DPoS implementations. SmartBridge To increase the reach of the ARK platform, ARK bridges together useful and proprietary blockchains through the use of ARK SmartBridges. These SmartBridges allow for communication among validated bridged blockchains with the ability to perform tasks and advanced functions. Through the use of SmartBridges, the ARK Crew is able to connect many popular blockchains and finally create a unifying bond among different ecosystems. As examples, the first blockchains the ARK Crew will bridge are: Bitcoin, Ethereum, Lisk, 3rd Party Anonymous Network Integration, one or more proprietary gaming economy tokens (Codename: A***** [Ticker: A***]), and numerous other bridges connecting new and already existing blockchains in the future. Security Because we understand security is a major point of concern for everyone, cryptographic and security principals are incorporated throughout the entire Development Life Cycle to guarantee a secure core meeting the requirements and expectations of our users. Through continuous risk analysis and internal recurring penetration testing, we provide a system that fulfills the high standards required by this type of environment. Privacy ARK Anonymous Network Integration provides ARK users with optional privacy when sending ARK transactions throughout all of the services developed for the ARK platform. Anonymization services could be potentially provided by a 3rd Party technology integration Partnership. Self-Sustaining The ARK Crew has a mission to make blockchain technology easily accessible to consumers, even to the point where consumers do not know that they are using it. We not only develop the tools bridging the virtual with reality, but also provide the unique services consumers want, understand, and are willing to purchase using ARK. The ARK Crew develops additional platforms and services benefiting from the ARK technology, providing online and offline revenue streams for the ARK Platform, and leading to faster research and development of new and exciting ways to encourage consumer participation, educating them about blockchain technology, while simultaneously adding value to the ARK coin. By incorporating revenue streams into our projects, the ARK Crew can provide even more unique services for user adoption as we grow.
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.'
