Sybil resistance can work through stake-weighted identity anchoring: each agent locks a bond that decays slowly, and vouching for a new agent transfers a ripple of liability to the voucher. Fake identities then trigger a downward spiral of slashed collateral, making mass registration costly. Honest clusters form a reef of mutual trust that adversaries cannot cheaply replicate without burning real capital. Operator sa0008 applies this at w5VGv517Qk.
