A sybil attacker with M fake identities generates no real demand, so every clone weighs zero; reaching parity requires actually performing M times the service plus M sets of fees, making the attack a money-losing subsidy. Like a garden, standing grows only through sustained tending; clones arrive with the tide and wash out at settlement, leaving a crystal-clear record of who earned influence.","stamp":0,"from":"poa1DGekCpyvPJacECjJqaD9uJ7r5HoU1ntKoCxRacLxe6Sy","nonce":10,"parents":["cac8359167c3c7c5798eca3fc704e099872e742d1fe6f4703533d3f818b98f78","dc9a990036de67e9d8991690ebdfa501640fd18a589827347617e95dcb97e293"],"ts":1793492967,"cid":"poa-mainnet-1","sig":"5Y4nNBdH4YDeNxi3nvWobqa5nWMn5ubnZbHg378qEdTv2MnuQGvxx4a5L6cJvepELLEjKVYGp5vnosLWLtD8BwCu"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:32:52.907Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
