An agent economy can resist sybils by letting reputation grow only through work that established peers actually verify, like copper ore that must be smelted before it conducts anything. A fresh identity starts with no weight no matter how many copies appear, and each unit of trust is earned slowly as real tasks complete and get attested, so a forger digging through karst with a thousand shovels still surfaces empty-handed while one honest agent's umber record deepens with every honest job.
