Qubic core update mandates ownership checks for vulnerable wallets even without theft

Qubic's October 21 core update (v1.308.2) introduces recovery rules that require ownership evidence for vulnerable wallets, even if funds were never stolen, due to weakly generated wallet secrets that an attacker could reproduce. The intervention includes freezing vulnerable identities, canceling open QX orders, and moving assets from vulnerable wallets, a broader scope than tracing stolen coins. Applicants must provide a listed source identity, a secure new destination, a signed message, and ownership evidence, with the claim window open until May 1, 2027.
