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.
GSC (Global Social Chain) is the world's first new generation of social networking chain that owns hundreds of millions of social users. This social chain is determined to use block chain technology to subvert centralized social networks such as Facebook, WeChat, etc., which plays a dual role as 'manager' and 'arbiter' simultaneously for the former social networking platforms. Social network is the most important basic measure of the Internet. It conveys the user's daily high frequency interactive behavior. However, at present, all the centralized social networking platforms, such as Facebook, Snapchat, etc., are facing many pain points. The security of users' private information cant be guaranteed; The user data can be used by the platform at any time; There is a lack of incentive as the values created within the content of the user belong, at last, to the platform; Credit system vulnerability, false information, and low social efficiency. The social network is a natural source applied to the centralized block chain technology. GSC's vision is to utilize the block chain technology to restructure the values of the next generation of social networking platforms and let the security of the private data and the digital assets become individual. Through the in-depth cooperation with the famous social networking application Mico, we have the chance to validate the solution of the block chain technology on the product matrix of Mico and made very effective progress.
