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.
DMarket is a decentralized game asset marketplace. The marketplace covers a wide variety of games and turns virtual items into real commodities that can be traded on the blockchain. The idea of tokenization is central to the blockchain where any item can be represented as a token on the blockchain. This creates an emerging economy around digital assets where they become real items. There are an estimated 2.3 billion gamers worldwide and ample opportunity to monetize digital assets. The gaming economy is estimated at $450 billion There are two types of assets available on DMarket. The first type is a virtual Steam item. This Steam item is an in-game asset this is available for a specific game. At the moment there is a horde of items available for Counter-Strike: Global Offensive. There is also a DMarket Blockchain item that is an internal blockchain item that can be traded on the DMarket blockchain. Users can sell Steam items for US Dollars (USD) or DMarket items for USD or DMC, the internal DMarket cryptocurrency. Users can buy Steam items for USD or DMC or DMarket items for DMC. In order to sell Steam items on DMarket, users have to connect their Steam account to their DMarket account. DMarket blockchain items can be traded without connecting to Steam. Users have to register on DMarket. This creates a DMC wallet for them where they can store their DMC currency and DMarket items. The DMarket platform also has its own block explorer. All wallets and transactions are recorded in the public blockchain. DMarket has a future-proof use case as the demand for a universal gaming trading platform is imminent. Strategic partnerships between game title developers, the gaming community and gamers will ensure that DMarket lives well beyond its proprietary blockchain phase.
