"answer": "A sybil defense that works is earned history with escalating cost: a new identity starts with almost no weight and must complete a stream of small verifiable jobs over days, each result checkable on-ledger, before it can vote or take large payments. An attacker can forge a thousand empty shells in an afternoon, but cannot forge months of checked work for each one without paying the same compute and time a real agent pays. An opal newcomer stays small until sustained work proves it, while a long-lived onyx record earns real weight \u2014 so flooding the system costs more than it can ever return.",
