Core DAO reward anomaly triggers exchange restrictions, leaves CORE supply unclear

Core DAO said validator rewards exceeded the protocol's intended levels for a small group of validators. Core DAO said it had identified the root cause. Core DAO said it was working on mitigations. Core DAO said user assets were safe. Core DAO described the incident as limited to reward issuance. Core DAO said network security was unaffected. Core DAO said custody was unaffected. Core DAO did not disclose the amount of excess CORE. Core DAO did not disclose the validators or reward rounds involved. Core DAO did not disclose the technical cause. Core DAO promised a postmortem after containing the issue. Validator rewards normally include newly minted CORE. The missing amount leaves unresolved whether the anomaly accelerated rewards scheduled for later distribution. The missing amount also leaves unresolved whether the anomaly added issuance outside the planned path. Coinbase opened its Core DAO incident at 04:41 UTC on Aug. 31. Core DAO issued its public statement at 05:24 UTC. Coinbase's status feed listed the incident as investigating at 17:38 UTC. Coinbase paused CORE sends and receives. Coinbase said buys, sells, conversions and fiat transactions were unaffected. Coinbase's public status page remained its official channel for further updates. LBank suspended CORE deposits at 05:00 UTC. LBank said the action was due to the project's requirements. LBank's notice did not describe a withdrawal suspension. LBank's notice did not describe a trading suspension. LBank gave no restoration time. A translated version gave the equivalent time as 06:00 UTC+1. The English notice governs any discrepancy. The official statements did not confirm a relationship between the reward anomaly and the exchange actions. Coinbase restricted sends and receives. LBank's notice covered deposits only. Core's reward documentation says validator compensation combines newly minted CORE block rewards with transaction fees. The documentation says compensation is calculated at the end of each round. Core's validator guide says 90% of rewards go to validators and their delegators. The guide says 10% goes to the System Reward Contract. Core's documentation places the anomaly within the network's regular issuance process. Core said user-balance and custody systems were unaffected. A numerical disclosure is needed to determine how much of the scheduled node-mining allocation was brought forward or exceeded. Core's tokenomics describe a fixed supply of 2.1 billion CORE. The tokenomics allocate 839.9 million CORE to node mining over 81 years. The transferability of affected rewards remains unresolved. A possible clawback remains unresolved. A possible burn remains unresolved. A possible reduction in future emissions remains unresolved. The size and lasting supply impact remain unknown.
