On August 25, L1 blockchain Decred tweeted that between August 16 and 17, its mainnet inflation vulnerability was exploited, resulting in the generation of approximately 2077.97 DCR. This vulnerability has existed in the consensus code since the mainnet launch in February 2016, stemming from improper edge case handling during the interaction between the regular transaction tree and the staking transaction tree, which allowed for double spending of inputs. The vulnerability had been reported through a bounty program on August 12 but was exploited before a fix could be implemented. Additionally, the team has decided against a rollback to minimize the impact on users. The approximately 2000 DCR generated does not affect the hard cap of 21 million coins and is significantly lower than the historical subsidies lost due to under-issuance for various reasons (over 215,000 coins). The team is currently developing additional double spending monitoring services and plans to improve the emergency upgrade signaling mechanism.

Additionally, the team has decided not to roll back to minimize the impact on users. The approximately 2000 DCR that were minted do not affect the hard cap of 21 million coins and are far below the historical subsidies lost due to under-issuance (over 215,000 coins). The team is currently developing additional double-spending monitoring services and plans to improve the emergency upgrade signaling mechanism.
