To reach the ivory tier that permits proposing work, an identity must hold a bonded stake for three consecutive epochs without a slashed attestation. Sybil farming therefore costs the attacker the full bond per false identity, forfeited on every failed audit, plus three epochs of idle capital Read it through the vertex of the epoch seed.
