Core DAO: CORE Transfers Frozen, Emergency Hard Fork Announced. What Our Chain Measurement Shows

If you hold CORE, one question currently comes before the price: the question of where it sits. If your holding is on an exchange, it may have been stuck since 31 August, depending on the provider. Coinbase has paused deposits and withdrawals on the Core DAO network, and several other trading venues have followed. The project itself speaks of validators that received markedly more reward than intended, and is preparing an emergency hard fork. We therefore went beyond the reports and queried the chain itself. On 2 September 2026 we retrieved and analysed around 13,000 blocks of the Core mainnet individually. The result yields three numbers that appear in no report: the number of block-producing addresses rose from 21 to 23 on 28 August and fell back to 21 on 31 August. In the early hours of 31 August the chain lost 181 blocks against its otherwise exact cadence. And at no point during that period did it stand still for longer than five seconds. What happened at Core DAO and who the transfer freeze affects Core DAO is an independent blockchain with its own token, CORE. Unlike a token that lives on Ethereum, it runs its own validators, which build blocks and are rewarded for doing so. That is precisely where the incident sits. On 31 August 2026 the project disclosed that a small number of validators had accumulated block rewards well above the issuance provided for in the protocol. A day later, on 1 September, Core stated that the matter had been contained and that the validators concerned could no longer draw excess rewards. According to the project, the incident affected only the issuance of rewards; user balances were said to be untouched. To close the fault permanently, Core is coordinating a hard fork with the validators. You are affected in the first instance if your CORE sits with a provider that has paused deposits and withdrawals on the Core network. You are affected in the second instance if you hold CORE in your own custody and want to move it over the coming days: in that case you should know whether and when the hard fork takes effect. What is not affected is your holding as such, because a forward upgrade does not reverse confirmed transactions. Validator, block reward and hard fork: the three terms in one sentence each A validator is a machine with staked capital behind it that is entitled to propose and confirm new blocks, and is paid for doing so. The block reward is the amount the protocol pays out to those validators per block; its size is fixed in the software and is not open to negotiation.
