With only 10 days to complete the mandatory update of Qtum Core wallets for the hard fork on July 31st, all users of the Qtum Core Wallet should update to version 22.1 as soon as possible.
The Qtum Mainnet hard fork will take place at block 2,080,512, approximately 8:40 pm GMT on July 31st (which may be on August 1st, depending on your time zone). The precise block height can me observed at https://qtum.info/
Users of the Qtum Core Wallet, or operating the Qtum Core Wallet as a node or blockchain interface, must update to version 22.1 (https://github.com/qtumproject/qtum/releases) as soon as possible, then the new features for Taproot and evmone will be automatically activated at block #2,080,512.
This mandatory update only applies to the Qtum Core Wallet, not any other types of Qtum wallets.
This update will add Taproot/Schnorr signatures, a new Ethereum Virtual Machine evmone, and bug fixes. See the release notes at https://github.com/qtumproject/qtum/releases/tag/v22.0
If users of the Qtum Core Wallet fail to update to version 22.1 before the hard fork they will temporarily lose control of their coins, and staking wallets will not receive mainnet block rewards.
