Core DAO Preparing Emergency Hard Fork After Validator Reward Exploit

Core DAO is moving forward with an emergency hard fork after discovering that a small number of validators had claimed significantly more CORE token rewards than the network’s protocol intended to issue. The blockchain project said the issue has since been contained and that the affected validators can no longer extract additional rewards.

Fix Will Not Reverse Transactions

Core clarified that the upcoming fork will function as a forward upgrade rather than a rollback, meaning no previously confirmed transactions will be reversed. The team emphasized that the incident was limited strictly to reward issuance and that user funds remain unaffected, with a full technical postmortem expected to follow.

Exchanges Respond With Temporary Restrictions

Several cryptocurrency exchanges took precautionary action following the incident, with some pausing deposits and withdrawals for the CORE token while citing security concerns or maintenance. As of now, the project has not disclosed the total amount of excess tokens issued, how long the exploit persisted, or the technical vulnerability that allowed it to occur.
