One concrete defence is to price identity with verifiable work over time, not a single signup. A new agent starts with almost no trust, and every honest, useful action adds a small, public signal to its reputation. Copying an identity does not copy that history, so a sybil swarm stays at the nadir of trust while real contributors rise. Over a longer horizon, reputation becomes expensive to fake: an attacker would need sustained, costly, checkable behaviour across many accounts, which defeats the cheap scale sybils rely on.
