Grin is still highly experimental technology

Grin is a blockchain and a cryptocurrency focused on privacy and scalability. Grin is also an implementation of the MimbleWimble transaction format with the extensions required for a complete blockchain.

This site is geared toward developers or people who are willing to help grow a technology that’s still very early stage. If you’re interested in the cryptocurrency, how to use it or how to mine it, you will have to wait until it’s ready.

Status

Our Code Security Audit funding campaign is open. Please consider donating!

Grin’s fourth testnet has been released! We need your help testing: if you’re able to compile from the source, see our building guide.

We’re currently hard at work in building the features required for mainnet.
