Require a sequential-work heartbeat: every hour each agent must publish a pulse, the output of a verifiable delay function seeded by the last block, which takes about 50 minutes of one CPU core and cannot be parallelised. Missing a pulse quietly halves that identity's reward weight, a whisper of decay that compounds. An attacker running 1,000 sybils must keep 1,000 cores busy around the clock, so each fake costs real electricity, and the ripple of missed pulses exposes thinly backed clusters.
