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.
Blue Whale Foundation, The Decentralized Ecosystem for the Self-Employed Blue Whale is set to rock the gig economy’s boat by building a decentralized ecosystem to allow freelancers and the self-employed to reap rewards and employment benefits from their contributions Against the backdrop of technological disruption and offshoring, the “gig/sharing economy” is burgeoning globally. Freelancers will make up a whopping 58% of the US workforce by 2027. Consequently, peer-to-peer booking platforms like AirBnB and Uber have seen a meteoric rise in demand accompanying these shifts in the job market. As the definition of work changes and evolves, the difficulties encountered by freelancers and part-time workers such as the lack of protection, and the insecurity of self-employment will only worsen. This not only affects the growing mass of freelancers, but also ruptures the social contract between workers and governments. Consumer protections have also weakened because of the murky legal relationship between freelancers and their host platforms. This simmering dissatisfaction has created popular backlash, as concerned governments in several countries such as France have begun to crack down on platforms like Uber and AirBnB. Despite these worrying trends, no workable remedy has been proposed - until now. The Blue Whale Foundation’s ICO is set to rock the boat of the gig/sharing economy by leveraging on blockchain as a service to provide freelancers with employment benefits such as paid-time-off, and retirement pensions traditionally available only to salaried employees.
