GRIN is a fully community-based open source project based on the MimbleWimble. GRIN fills in the missing parts of the MimbleWimble protocol, with strong privacy protection, block scalability and data auditability.
At the same time, GRIN is launched fairly, free of ICO, pre-mine or founder’s reward. GRIN is entirely driven by the community.
Supply：GRIN uses a constant emission of 1 grin per second (60 per 1-minute block)
