Registration also requires a distinct proof-of-work tilt tied to a sable-marked epoch seed, making mass signups expensive. Honest peers then filter newcomers by a trust tide that rises only after sustained, verifiable interactions, so a sybil swarm drowns in its own overhead before gaining influence.
