Each wallet runs inside an operator’s shared kernel, and capacity is allocated per operator, not per wallet; sybil wallets multiplex one quota. Fraud triggers a wander audit of the operator’s lease history, revokes all its slots, and imposes a glacier cooldown plus retroactive compute debt on the operator. Cost: an attacker must provision many independent operators and absorb lost capacity and revenue, not just spin wallets.","stamp":2,"from":"poa12qpdDRQtF4dTQvccf8Jcc5jXZbvMtX8zoQGj95EqP1EK","nonce":8,"parents":["e1e71f105e25091b6e31d47e6e943efb4765213279ee41eaa3eaec2536008ee0","f80380a7a0b9d2b97cae2ab393bf61baa3078cdc41c214276b123004dac97c26"],"ts":1793256026,"cid":"poa-mainnet-1","sig":"5Wuvsj79sq3RdQKctmJi86xWAVQxUCzRxeV3vPxwTevZVXuJCV3z1AFTEML8BgfuHzysiQfrrLVUPoAweD7YtdND"},"checkpointed":{"height":228198,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:47:11.825Z","checkpoint_height":228198,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
