Verge coin started its cryptocurrency journey in 2014, going by the name of DogecoinDark. The reason it was created was to create a truly private cryptocurrency. The founder of Verge felt that Bitcoin wasn’t anonymous, so he decided to build a new blockchain where transactions could not be traced. Verge uses multiple anonymity-centric networks such as TOR and I2P. The IP addresses of the users are fully obfuscated. The Core QT wallet has built-in TOR integration as well as SSL encryption which adds an extra level of security. Verge is an open source project with an active team of developers from all over the world. The development team is always in close contact with the community. Verge is not a private company funded through an ICO or premining. Wraith Protocol is a technology upgrade package that enables our users to be able to send and receive payments privately across our blockchain by enabling stealth addressing services. Additionally this update removes our QT wallet users off of clearnet and migrates everyone to SSL enabled Tor. Verge focuses on security and maintaining user anonymity just like Monero; so that is its latent upside. Many investors are also applauding its unique technology. Having been improved and integrated with the Wraith Protocol technology, verge users are now able to effortlessly switch between private and public ledgers on the Verge blockchain. Before this, private and public ledgers were mutually selected, meaning that they could not co-exist on a very similar blockchain. But investors are today free to use whatever ledger they want. A good example was when Wraith Protocol switched ON – one will not be able to view the transaction data, not even via the blockchain explorer. Additionally, Verge makes obscure the IP addresses in both instances. When coupled with Wraith Protocol Verge certainly becomes the only undetectable cryptocurrency. Furthermore, transaction speed on Verge is light speed at 5 seconds only, using Simple Payment Verification technology. Verge also maintains a community feel since it’s not a private company. Community members are responsible for the direction of its technology and where the coin heads next. It currently offers a number of secure mobile wallets, including the Tor Android Wallet, which offers mobile anonymity, another big plus over Bitcoin. Verges offers five different Proof-of-Work algorithms for mining. They include; Lyra2rev2, Scrypt, X17, blake2s and myr-groestl. Offering a choice of five different algorithms promotes inclusion, since a wider variety of users will now have an opportunity to not only mine but influence the network. Should one algorithm demand greater mining resources, users get an option of just switching to a different one.
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.'
