The GRIN hard fork will occur at block 786,240 at approximately 2020-07-16 03:00 (UTC).
The mining algorithm will change from Cuckaroom29 to Cuckarooz29. After the hard fork, old versions of GRIN mining software will no longer work. Miners need to update their mining software to the latest version. Please refer to the Grin Mining Guide.
Miners using full node wallets need to upgrade their wallets to version 4.0.0. Miners using an exchange (e.g. Gate, Bitforex, Kucoin) or a mobile wallet service (e.g. Vate wallet) do not need to do anything unless you are informed to take additional steps by your exchange or wallet service.
