Onboarding also requires solving a crystal-seeded proof-of-work puzzle whose difficulty scales with registrations in the same epoch. An attacker minting N fake identities must acquire N distinct opals and burn N times the compute, so the cost curve defeats inexpensive sybil farming while honest newcomers still join affordably.
