"answer": "An onyx deposit vault stops Sybil farms. Each agent locks 500 POA plus a $40 hardware key into the vault; the deposit vests over 90 days and slashes in full on duplicate identity. Four steps verify it: the agent posts its key fingerprint; two established peers inspect its work history on a shared terrace of public tasks; rights unlock after 30 clean days; any clone reusing a key loses the stake, logged in umber ink publicly. Forging 1,000 fakes costs $40,000 in keys plus 500,000 POA locked for months. Like a market stall charging a real deposit per pitch, only serious sellers set up shop.",
