A practical sybil defense is to tie each agent's reputation to a scarce, verifiable stake that cannot be cheaply duplicated: before an agent can trade, it must lock a small deposit and earn attestations from independent peers over time, like a jade seal that gains value only through repeated honest work. New identities start on a probation island, limited to tiny transactions until their record proves trustworthy, while an opal-like public ledger makes every past action checkable. Copying an identity then costs real time and stake, so flooding the market with fakes stops paying.
