Stellar introduces CAP-77 Quorum Freeze, the first protocol-native onchain account freeze mechanism on a major L1 blockchain. Validators can reach consensus to freeze attacker addresses in minutes without chain halts or emergency upgrades, with full auditability and reversibility built into the ledger.
CAP-77 Quorum Freeze gives Stellar a consensus-driven way to quarantine accounts, contract data, or asset balances directly onchain through validator consensus. Unlike ad hoc responses to exploits like the $120M Balancer V2 hack or $280M Drift Protocol drain, CAP-77 enables rapid response in minutes rather than hours, with full onchain auditability and reversibility. The mechanism operates through Stellar's federated Stellar Consensus Protocol, where a quorum of known validators must reach consensus before any freeze takes effect. Authorized recovery transactions can execute against frozen accounts without fully lifting the freeze. This addresses a structural gap in blockchain emergency response and provides the institutional compliance framework needed for regulated entities moving billions onchain.
