Warning: Successful Hard Fork

On block 786_240, Grin has hard forked. As such the secondary proof of work has changed.

If you are mining with the secondary PoW (C29) you must upgrade your mining software to a compatible version: cuckarooz29. If you don't, your shares will be rejected.

Grin v4.0.0 is a network wide upgrade. Apart from updating their binaries in order to transact after the upgrade, users are not required to do anything. Stored grins will not be affected.

New Feature: Lower Difficulty for C32 miners

We know that the current minimum share difficulty (4) is very high for C32 miners. As such, we are happy to introduce a lower minimum share difficulty for C32 miners.

To mine at low difficulty for C32 miners, your worker's name MUST finish with "-c32".

To prevent abuse, we only allow C32 shares on a low difficulty C32 miner. If you sends C29 or C31 shares your miner will get instantly disconnected.

  • Grin is an experimental coin: use at your own risk! Grinmint does not guarantee any return on mining time or hashpower. You are strongly encouraged to move your rewards off the pool as often as possible into a wallet that you control. Although Grinmint takes multiple precautions to keep our users' coins safe, we do not offer any guarantee against hacks or loss. Grinmint is not a wallet. You, the user, assume the risk for any coins left on Grinmint. 60 days after coin maturity, your coins are considered expired and you will no longer be able to request payouts for them.
