Meet Grin – the private and lightweight mimblewimble blockchain

Electronic transactions for all. Without censorship or restrictions.

Grin empowers anyone to transact or save modern money without the fear of external control or oppression. Grin is designed for the decades to come, not just tomorrow. Grin wants to be usable by everyone, regardless of borders, culture, skills or access.


Grin has no amounts and no addresses. Transactions can be
trivially aggregated. To hide where a newly created
transaction comes from, it gets relayed privately (a
“random walk”) among peers before it is publicly announced.


MimbleWimble leverages cryptography to allow most of the
past transaction data to be removed. This guarantees Grin
won’t crumble under its own weight in the long term.


Grin is developed openly, by developers distributed all over
the world. It’s not controlled by any company,
foundation or individual. The coin distribution is designed
to be as fair (but not gratis) as is known to be possible.

MainNet, Onwards!

We’re currently hard at work in stabilizing Grin for our
mainnet release, around Jan. 15th 2019.

Check out our feature list and jump in.

Grin is launched fairly, free of ICO, pre-mine or founder’s reward. We rely on donations to keep working on the project. Support the movement by purchasing some swag or making a donation.

We sincerely thank all our past patrons for their support.
