Update: the issue is contained and the malicious validators can no longer draw excess rewards. We're now coordinating an emergency hardfork with validators to deploy the permanent fix. This is a forward upgrade, not a rollback. Assets remain safe. Full post-mortem to follow.

Core Network — Status Update We're aware of an issue causing a small number of validators to accrue block rewards above the protocol's intended issuance. The root cause is identified and mitigations are in progress. User assets are safe. This affects reward issuance only, not the network's security or the custody of any funds. Full post-mortem to follow once contained.

Core steps its block reward down every year instead of halving it @Coredao_Org caps coredaoorg:native at 2.1 billion tokens, a figure its documentation describes as exactly 100 times Bitcoin's 21 million. New supply enters through block rewards, the tokens paid to the validators producing each block, spread across an 81-year schedule per Core's whitepaper. Rather than cutting the reward in half every four years the way Bitcoin does, Core steps its emission rate down at every 10,512,000th block. At the network's roughly three-second block time, that lands about once a year. Each step is far smaller than a Bitcoin halving but is more frequent, with the schedule running until the full 2.1 billion cap is distributed.
