Decred Reveals Mainnet Inflation Bug That Minted 2,077.97 DCR, Rules Out Chain Rollback
AI Market Summary
Decred disclosed a long-standing mainnet inflation/double-spend vulnerability exploited Aug 16–17, minting ~2,077.97 DCR before a patch could be deployed. Although the team will not roll back and the incremental issuance is small versus historical subsidy shortfalls, the incident highlights consensus-risk and emergency-response gaps, which can weigh on risk appetite across smaller L1s and marginally pressure broader crypto sentiment in the near term.

Decred said a mainnet inflation vulnerability was exploited between Aug. 16 and 17, leading to the creation of about 2,077.97 DCR, according to information circulating on X and cited by ChainThink.
The project said the flaw has been present in the consensus code since mainnet launched in February 2016. It stemmed from improper handling of edge cases when the regular transaction tree interacted with the stake transaction tree, enabling double-spending of inputs.
Decred noted the issue was submitted via its bounty program on Aug. 12, but was exploited before a patch could be deployed. The team said it will not roll back the chain, citing the goal of minimizing disruption to users.
Decred added that the roughly 2,000 extra DCR does not change the network's 21 million supply cap and is well below the historical subsidy shortfall tied to missed votes and other factors, which it said exceeds 215,000 coins. The team has built an additional double-spend monitoring service and plans to strengthen its emergency upgrade signaling mechanism.
