Cosmos 커뮤니티의합의 Bounty Proposal Atoms can be inflated and reserve pool funds spent with the passing of a BountyProposal. Incentivizing Hackers The security of the Cosmos Hub is a function of the security of the underlying validators and the choice of delegation by delegators. In order to encourage the discovery and early reporting of found vulnerabilities, the Cosmos Hub encourages hackers to publish successful exploits via a ReportHackTx transaction that says, "This validator got hacked. Please send bounty to this address". Upon such an exploit, the validator and delegators will become inactive, HackPunishmentRatio (default 5%) of everyone's atoms will get slashed, and HackRewardRatio (default 5%) of everyone's atoms will get rewarded to the hacker's bounty address. The validator must recover the remaining atoms by using their backup key. In order to prevent this feature from being abused to transfer unvested atoms, the portion of vested vs unvested atoms of validators and delegators before and after the ReportHackTx will remain the same, and the hacker bounty will include some unvested atoms, if any. https://cosmos.network/docs/resources/whitepaper.html
