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.
DAOstack is an operational stack for DAOs, a comprehensive toolkit for decentralized collaboration at scale. It provides the governance and economic framework needed for collectives to self-organize around shared goals and interests. DAOstack is based on a fully open, modular and upgradable architecture. DAOs are open, self-organized collectives coordinated by economic incentives and self-executing code, cooperating around shared goals. Powered by the network effect, DAOs provide a revenue model and incentive for the production of open, shareable resources (such as open-source code and a music file). With the creation of more open resources, the DAO will be able to scale indefinitely while keeping its agility and coherence,and in many cases out compete existing corporate structures. DAOs have attracted top talents in the blockchain space, holding promise for more efficient and resilient organizations. Despite this, they have lacked critical elements to be successfully deployed so far, and in particular an adequate decentralized governance system. DAOstack is an operating system for DAOs. With DAOstack, thousands of open-source creators can jointly produce decentralized applications (DApps), while distributing individual ownership in the product to contributors of value. Crowd curators can cooperatively own and manage multi-valued ranking systems to compete with Yelp, TripAdvisor, or YouTube. And autonomous networks can run their collective investment or insurance fund. We believe DAOs will radically change the way people organize, from startups to corporations, to nonprofits and even nation-states. DAOstack develops the foundational elements needed to enable this transition to the future of work.
