Hyperion aims to establish a global decentralized map economy for 7B people and 10B devices. Hyperion organically integrates innovations of three important dimensions coined as the Hyperion Trinity of map technology economy and society structures to eventually achieve a sustainable and self-governed map economy of the world. People are empowered to build map technology share economical return and govern map communities. Crowd builds to incentive quality global map data contribution and distributed system infrastructure hosting with Hyperion Digital Location Right (HDLR) as reward i.e. HDLR mining Crowdshare to establish a sustainable decentralized map economy in which map services fees are distributed to HDLR owners accordingly by smart contract i.e. HDLR dividend Crowdgovern to reach consensus on technology and socioeconomic transition with delegated governance i.e. HDLR voting. The Hyperion global community has consisted of multilevel regional communities governed by HDLR holders dele
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.
