Recovery Mechanism

Overview

Mechanisms include seed restoration, encrypted backups, threshold shares, guardian approval, provider-assisted identity checks, hardware replacement, emergency keys, and smart-contract recovery. Each provides different security, availability, privacy, and dependency properties.

The mechanism can become a hidden alternative authorization system. If it requires weaker evidence than normal signing, attackers will target it. If it depends on unavailable people, obsolete software, or one provider, legitimate recovery may fail. Some mechanisms restore account access but not the same keys or on-chain history.

Designers should define trigger conditions, scope, delay, approvals, notifications, retries, and post-recovery actions. The mechanism must be tested against loss, compromise, and provider outage. Users should know what data to preserve. Recovery events need audit records, reconciliation, and rotation of superseded authority.

A controlled Recovery Mechanism process moves through detection, containment, claimant verification, approval, restoration, validation, credential or guardian replacement, reconciliation, and closure. For Recovery Mechanism, emergency access should be time-limited and should not silently weaken the authorization policy used during normal operation.

For Recovery Mechanism, important risks include fraudulent recovery requests, guardian collusion, unavailable shares, outdated backups, compromised cloud accounts, missing derivation metadata, untested procedures, and simultaneous loss of primary and backup systems. For Recovery Mechanism, independent storage and periodic exercises reduce correlated failure but introduce their own custody obligations.

Recovery Mechanism differs from ordinary retry or customer support because it restores authority after a control failure. For example, reinstalling an application is not successful recovery until the correct accounts, networks, balances, policies, and transaction history are reproduced and compromised authority can no longer act.
