Grin seeks to fill in the gaps of the private and light weight MimbleWimble blockchain protocol in oder to deploy a fully functional Grin blockchain and cryptocurrency platform. The Grin cryptocurrency is made to be private, scalable, and open source. The Grin project is fully funded by donations, and did not hold an initial coin offering (ICO), pre-mine, or founder's reward.

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.

The consensus algorithm used by Grin is the Cuckoo Cycle proof-of-work based. There are 2 hashing algorithms involved with Grin.

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.
