cooperative delegation

Definition

The way KERI addresses the security-cost-performance architecture trade-off is via delegation of identifier prefixes. Delegation includes a delegator and a delegate. For this reason we may call this a cooperative delegation. This is a somewhat novel form of delegation. A major advantage of cooperative delegation is the delegator’s key management protects the delegate’s via recovery by the delegator. With cooperative delegation, any exploiter that compromises only the delegate’s authoritative keys may not capture control authority of the delegate. Any exploit of the delegate only is recoverable by the delegator.
