Core DAO plans emergency hard fork after validators claimed excess rewards

The planned hard fork is described as a forward upgrade and will not involve a network rollback or the reversal of any confirmed transactions. This measure follows an earlier update where Core DAO acknowledged that a small number of validators had accrued rewards significantly above the protocol's intended issuance.

Around the time of the incident, several cryptocurrency exchanges took action. Coinbase temporarily paused sending and receiving transactions on the Core network. Bithumb and Coinone suspended deposits and withdrawals, citing suspected or confirmed security concerns. Bitget also halted CORE deposits and withdrawals, attributing it to wallet maintenance, while LBank suspended deposits due to project requirements.

Core DAO has not yet disclosed the total amount of excess CORE issued, the duration of the activity, or whether the additional tokens entered circulation. The specific vulnerability that enabled validators to obtain the extra rewards also remains unexplained. However, the DAO has committed to publishing a detailed technical postmortem.
