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.
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.
