The GRIN hardfork has completed at block 786,240 at 2020-07-17 08:28 (UTC).
From this hard fork upgrade, the Grin-29 algorithm has been changed from Cuckaroom to Cuckarooz. Old versions of GRIN mining software are no longer supported. Miners need to update their mining software to the latest version. Please refer to the COIN NOT FOUND: GRIN.
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.
