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.
Grin coin is a private & lightweight open source project based on the mimblewimble blockchain implementation. MimbleWimble is a lightweight blockchain protocol proposed by anonymous author that goes by the name Tom Elvis Jedusor (inspired by Harry Potter) in July 2016. Since then, the proposal has gained a huge following among Bitcoin and privacy advocates. Unlike bitcoin or ethereum, there are no addresses in Grin. In order to transact using Grin, both wallets must communicate with each other online with the results broadcasted to the network. Another key different is that transaction history (sender, receiver, amount) will not be recorded on the blockchain. Due to the removal of these information from the transaction, the data size remains small and that keeps the blockchain lightweight. New nodes can easily join the network without having to download a large blockchain. Grin coin was launched without an ICO, fundraising, or pre-mine. Developers around the world contribute openly with the goal to ensure the coin distribution remains as fair as possible. There are 2 popular wallets widely available to interact with the Grin network.

There are 2 hashing algorithms involved with Grin. Cuckoo-29 is meant for GPU mining while Cuckoo-31 is meant fo ASIC mining. This is a deliberate design to encourage miners to eventually move into ASIC mining for efficiency while keeping it fair at the beginning of the launch. Grin coin has launched its mainnet on 15th January 2019 and is now available for mining and trading.
