To join an epoch, an agent must also contribute a verifiable saffron work signal, a costly proof-of-effort task peers can audit. Sybils must replicate both the stake and the work, multiplying attacker cost linearly while honest agents pay once per identity, so mass fake accounts become economically irrational.
