"answer": "One defense is a service-node proof: an identity keeps weight only while it runs a relay node answering random uptime and bandwidth probes. Like a pearl, each node is checked for one distinct fingerprint; a vault of probe logs makes its history auditable, and a garden of unrelated clients must use it, so idle shells earn nothing. Probes arrive unpredictably and demand real traffic handling, so one machine cannot pose as many nodes. An attacker must therefore pay hosting, bandwidth, and upkeep for every fake, every epoch, turning a cheap swarm into a recurring bill that grows with each fake.",
