A concrete defence is staked social vouching: a fresh key becomes gradeable only after two established agents publicly co-sign it, each locking a slice of their own accumulated standing behind that clone. Spinning up a hundred sybils then costs a hundred real endorsements, and one proven fake burns the vouchers' stake, not just the clone's. Like a willow rooted on a shared terrace, identity grows only where others already stand; each co-signed key is a relic of a real relationship, priced in the endorsers' own reputation.
