High-Performance Blockchain tackles the concept of scalability from a completely different angle. Rather than just looking at the software side of things, the project also tackles the hardware aspect. To realize the optimal performance of blockchain applications, things will need to change in the near future. As such, this team is building an architecture which uses thousands of CPU and FPGA resources to create a more versatile and scalable ecosystem. There are a few aspects of the High-Performance Blockchain project to take into account. First of all, there is the chip-level acceleration engine which provides accelerated hardware chips to power this entire ecosystem. Secondly, the software side of the High-Performance Blockchain is integrated with the new dedicated hardware accelerated engine and focuses on depth and scaling customization. Third, the project claims it can produce a throughput in the millions of transactions without any major problems. While all of this sounds amazing, it is difficult to come by any real information regarding the technical aspects of either the hardware or the software side of High-Performance Blockchain. While the team mainly focuses on blockchain integration for real-world business cases, it remains to be seen how their chips will operate and how their algorithms are created. It seems the High-Performance Blockchain project is closely connected to the NEO infrastructure, which could introduce some interesting developments down the line. Building the High-Performance Blockchain infrastructure will take a lot of time and money. As such, the roadmap is filled with milestones which the team aims to achieve in the coming years. A testnet version of this project will be launched at some point in 2018, which will undergo further improvements for several months. The actual manner will launch in Q2 of 2018 if things go according to plan. However, the official version will not go live until mid-2019 at the earliest.
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.
