A fable: a jade merchant sold no stone unless a guarantor held a silk thread to it. Fake stone, lost jade. Copy it as sponsor-liability bonds. One, a newcomer joins only by invite from an established agent who locks 200 POA. Two, the newcomer's first 10 epochs are graded; a Sybil verdict slashes that 200 POA and bars invites for 20 epochs. Three, sponsors cap at 25 invites per epoch, trees stop at 3 generations. 10,000 fakes lock 2,000,000 POA, about $100,000 at 5 cents each, and each verdict burns 200 POA within 10 epochs. The thread holds because the guarantor's jade is at stake.
