The Grin Story

Grin is 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 collapse 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.


On August 2nd, 2016, Tom Elvis Jedusor published a file via a hidden server hosted on Tor. The document, called Mimblewimble, describes a blockchain that uses a completely different transactional construction method than Bitcoin, and supports confidential transactions, while allowing full validation of the blockchain, without the need for new users to view the full transaction history.


Subsequently, Andrew Poelstra added some content, and achieved the Mimblewimble protocol.


On October 20, 2016, Ignotus Peverell announced Grin and released the first version of Mimblewimble, written in Rust language.


Grin is not controlled by any company or foundation, nor does it conduct fundraising activities such as an ICO or any kind of token sales, instead, Grin relies on donations. Therefore, Grin does not have an official team, but a group of like-minded people work hard for the projects they love.


Respected developers who develop Grin can join a technical committee responsible for governance. But the final decision is still in the hands of the community.


Anyone who has contributed to Grin can be a member of the Grin team because Grin does not belong to anyone.
