Qtum is a decentralized and open-source smart contracts platform and value transfer protocol. Qtum uses proof-of-stake consensus, meaning node operators are rewarded for validating transactions. It is a DGP governed blockchain where community participants can vote to change certain network parameters. Qtum is built on a bitcoin core fork, but the foundation has created its own hybrid blockchain with the help of several key tools. The coin uses bitcoin’s chain because of its simple and stable nature, allowing the foundation to build upon it more easily. As the QTUM project is a hybrid of Bitcoin and Ethereum, its team comprises of members from both Bitcoin and Ethereum community. They also have team members who formerly worked with Tencent, Alibaba, Nasdaq etc. Apart from that, they are backed by some notable VCs and prominent people from the Blockchain community such as Patrick Dai (Project Co-Founder), Neil Mahi (Chief Blockchain Architect/Co-Founder) and Jordan Earls (Lead Developer/Co-Founder). Qtum provides a Turing-complete blockchain stack and is able to execute smart contracts and decentralised applications like the Ethereum blockchain. Qtum builds on Bitcoin's UTXO transaction model and uses the Proof-of-Stake algorithm. It is backed by some highly prominent members of the blockchain community such as Anthony Di Iorio, Xu Star, Bo Shen, David Lee, Jehan Chu and Roger Ver. Qtum sold over 10 million dollars’ worth of its tokens after only 90 minutes, eventually raising a total value of $15.7 million before stopping the campaign early after only 5 days. They raised a total amount of 11,156.766 bitcoins (BTC) and 77,081.031 ether (ETH) in exchange for the 51 million Qtum tokens being distributed to the public. In Qtum’s whitepaper, 51% of the coins were distributed to the public via the crowdfunding campaign. Of the remaining 49%, 29% of the coins would be allocated as community incentives, and the remaining 20% would be distributed to the early backers and development team.
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.
