Open-source blockchain for confidential transactions based on the MimbleWimble protocol
Grin is one of the first adopters of the MimbleWimble protocol. The development and launch of Grin are community-driven. The funding, for example, comes from donations and revenues from “swag” sold on the Grin’s website. No single entity controls the network and there is no premine and founder rewards.
Some contributors are credited by the community for their big contribution, such as Tom Elvis Jedusor for his formulation of MimbleWimble, Ignotus Peverell for starting the project, and more. The launch of Grin is exciting for a lot of communities, like Bitcointalk who accepts Grin as payment for those who got IP-banned on the forum.
