HYCON, which stands for Hyper-Connected Coin, is the digital asset built on top of a faster and more scalable blockchain developed by the Infinity Project team in Gangnam, Seoul. Using a DAG (Directed Acyclic Graph) structure, it has the capability to publish several blocks simultaneously with the ability to resolve conflicting transactions and reject double-spends through the SPECTRE consensus algorithm. This makes HYCON a next-generation cryptocurrency which can be used in the real economy. Honest transactions can be confirmed or rejected definitively in mere seconds, due to the high volume of blocks published within that time interval. Transactional throughput up to 3000Tps on a 2MB/s connection can be achieved as a starting point of the project. The DAG structure coupled with the SPECTRE protocol allows for network latency to be essentially removed as a limiting factor on transactional throughput. Blocks that are received out of order can still be ordered based on their implied position in the DAG rather than the time they were received. HYCON is Phase 1 of the Infinity Project Ecosystem and positioned for wide adoption as an efficient medium of exchanging value for enterprises, small businesses, governments, NGOs, and individuals. Together with the Infinity blockchain, HYCON will power the Infinity Platform (Phase 2) and Infinity Decentralized Exchange (Phase 3). The Infinity Platform will feature a simple and intuitive user interface to empower anyone with the ability to create their own customized and private Infinity blockchain. For example, enterprise solutions built upon the Infinity Platform will help increase accountability, enhance transparency, and improve data security, thus bringing value to companies and society.
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.
