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.
Steem is a cryptocurrency that rewards users for community building by posting and upvoting valuable content for others. Steem was inspired from the success of Reddit where the community helped enrich the shareholders. Steem aims to help distribute the rewards to the community members who help create the community in the first place. Steem aims to provide various services to its members such as a source of curated news, Q&A, job boards etc. The founders of Steem came from BitShares with Dan Larimer involved as well. Steem’s main platform, called Steemit, is a social media network built on top of the Steem blockchain. Steemit is similar to popular content-driven social networks like Reddit and Medium, but it rewards users with cryptocurrency for their participation. Fundamentally, the more value a particular piece of content provides to a greater number of people, the more the individuals responsible for creating and curating that content can earn. Users cast votes, creating a hierarchy of content. The more upvotes a post gets, the more it will earn. The platform also allows for downvotes, giving participants more flexibility when it comes to rating content. Steemit is meritocratic, meaning users that hold more currency can cast votes with greater influence. The Steemit community even has another service to offer to its customers. D.tube, which is considered to be very similar to YouTube, is Blockchain based and the users can realize the difference between the traditional video publishing websites and D.tube, as the amount of money earned is also displayed beside the post apart from likes shares and comments. The Steemit community is accused of posting plagiarize contents on their publishing website. The irony seems to be reaching highest levels when the original content doesn’t receive much appreciation and income than the copied versions of it.'
