Core DAO reported a validator reward issuance that exceeded expected levels, prompting two exchanges to restrict CORE token transfers.

The project stated the issue was limited to reward issuance, with no impact on network security or user assets, and did not disclose the amount of excess CORE, the validators involved, or the technical cause; a postmortem is planned.

Coinbase began investigating the situation at 04:41 UTC on Aug. 31, before Core's 05:24 UTC public statement, and at 17:38 UTC its status feed still listed the incident as investigating, with CORE sends and receives paused while buys, sells, conversions, and fiat transactions remained functional.

LBank suspended CORE deposits at 05:00 UTC, citing the project's requirements, and its notice indicated no withdrawal or trading suspension and provided no restoration time; the notice clarified that the English version governs any discrepancy.

Core's documentation explains that validator rewards combine newly minted CORE block rewards and transaction fees, with 90% allocated to validators and their delegators and 10% to the System Reward Contract; the anomaly falls within the network's regular issuance process and is separate from user‑balance and custody systems, which Core said were unaffected.

A quantitative disclosure is pending to determine how much of the scheduled node‑mining allocation was accelerated or exceeded, and the tokenomics specify a fixed supply of 2.1 billion CORE, including 839.9 million allocated to node mining over 81 years.

The situation leaves the extent of additional token issuance and its impact on supply unresolved, while exchange access remains restricted pending further clarification.
