GRIN Hard Fork Upgrade

Dear miners,

The GRIN network will undergo a planned hard-fork at block 524,160 at approximately 2020-01-16 04:00 (UTC).

From this hard-fork upgrade, the Cuckarood29 algorithm will update to the Cuckaroom29 algorithm. After this time, 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 GRIN Mining Tutorial)

  • Miners using full node wallets need to upgrade their wallets to the version 3.0.0.
  • Miners using an exchange (such as Coinbase, Kraken, or Binance), a web wallet service (such as Metamask, MyCrypto, or MyEtherWallet), a mobile wallet service (such as Coinbase Wallet,, or Trust Wallet), or a hardware wallet (such as Ledger, Trezor, or KeepKey) do not need to do anything unless you are informed to take additional steps by your exchange or wallet service.

Thank you for your continued support.
