Grin is a cryptocurrency project committed to providing privacy, scalability, and fungibility with several unique properties: It uses a privacy protection blockchain format named MimbleWimble; very little data is saved on the blockchain, making it cheaper and easier to run complete nodes; Mimblewimble is developed by an anonymous group operating all over the world; there is no pre-mined PoW mechanism, therefore fair and decentralized.
Grin is the first project attempting to realize the MimbleWimble protocol. It aims to allow everyone to trade or deposit modern currencies through Grin without having to worry about external control and oppression. Its electronic transactions open to the public are free from censorship and restrictions.
