Vertcoin is a decentralized currency owned by its users, a P2P cryptocurrency in the same vein as Bitcoin and Litecoin. Like its two predecessors, Vertcoin exists solely as a currency, and it uses proof of work to reach distributed consensus. Unlike its two predecessors, however, Vertcoin is dedicated to keeping its mining functions decentralized, so contrary to most PoW coins, it’s ASIC resistant. Branding their project as “The people’s coin,” Vertcoin’s team believes that ASIC resistance invites a fairer, more democratized currency for both users and miners. Along these lines, Vertcoin sports its very own 1-click miner, a program meant to make mining more accessible to the general public. The motivation of Vertcoin was the fact that Scrypt-based ASIC mining chip that is used to mine Scrypt derivative coins such as Litecoin and Dogecoin is entering the mass market. That coupled with strong mining pool causes the strength of a cryptocoin to drop as it becomes easier for a specific party to pull a 51% attack and even monopolize the network. Scrypt-Adaptive-Nfactor was created to address that issue. Vertcoin is zero premined and as of the current design, only 84 million coins would ever be created. Vertcoin is said to be the next generation of coins due to its unique hashing algorithm. There may be more altcoins created based on this hashing algorithm in order to defend their network against ASIC miners. Like most all pre-2015 coins, Vertcoin took a deathblow after Mt. Gox was hacked, throwing the entire market into a crypto winter. As such, it was relatively inactive until the revival last spring/summer. Since then, it has had steady climb up the market cap ladder. A 2014 International Business Times article mentions Vertcoin as a potential Bitcoin successor. The article notes that it ''hopes to offer an alternative. By taking the foundations of Bitcoin and making some adjustments, Vertcoin punishes miners who use powerful machines and work together in 'pools' to monopolise the mining market.'' On July 1, 2014, Vertcoin released a wallet supporting Stealth Address transactions. On December 13, 2014 (block 208301), Vertcoin forked from Scrypt-Adaptive-N proof-of-work function to Lyra2RE as a proactive defense against emerging Scrypt-Adaptive-N capable ASICs. On August 10, 2015 (block 347000), Vertcoin forked from Lyra2RE to Lyra2REv2 because a botnet was controlling more than 50% of the hashing power of Vertcoin network. On May 7, 2017, Segregated Witness (SegWit) feature was activated in the main network. SegWit update includes the Lightning Network technology that was also demonstrated in action during the same day.'
Dragonchain is one of the newly launched cryptocurrencies that is attracting crypto enthusiasts following its relaunch. The coin seems to be leading on the technology front irrespective of its market capitalisation trends, which is why it's also being anticipated to be Ethereum’s competitor. Dragonchain is a hybrid blockchain platform, where sensitive business logic and smart contract functionality is held by the owner. Its cryptocurrency is denoted by the symbol DGRN & has a total supply of 433,494,437 coins. Dragonchain uses serverless smart contracts from its pre-built library. This feature is unique to this cryptocurrency, as it can create smart contracts, with or without cryptocurrencies. Dragonchain was developed by Joe Roets who is its CEO and Chief Architect with a team of 4 core developers. The team is backed by a strong advisory board with Jeff Garzik on board who is established icon in the Bitcoin network. It was developed after exploration of 20 use cases and applications. It was released under the Apache 2 license in October 2016 to integrate real business applications onto a blockchain, protect business data and operations, currency agnosticism and multi-currency support. The launch of Dragonchain Foundation, a non profit corporation, in January’17 maintains the ownership and responsibility of Dragonchain’s open source code. Enterprises can easily design smart contracts in a variety of languages like Python, Node, C# & Java. The contracts can be specific to their business needs to include both private internal and public blockchain interactions. The Currency Smart Contracts help organizations to retrieve and transfer specified currency amounts between wallet addresses and check balances which can be run on schemas like ERC20, ERC223, etc. Dragonchain helps enterprises to leverage their models using blockchain by allowing development and integration before the economic model is known. Monetization can be applied after sufficient real data is available & system is functioning. DragonChain’s platform is establishing a niche in the crypto world with its layered security feature. The 5-layer security model adds great credibility to their overall goal of facilitating business integration into the blockchain. Additionally, DragonChain is seen as a strong rival to Ethereum because of the platform’s ability to scale; an issue that Ethereum has been notorious for. As of January 2018, the DragonChain team is raising funds and finishing development of the platform. Although the exact date is currently unannounced, the DRGN platform is expected to fully launch sometime this year.
