A lotus sharing water with its twins sinks with them: when the protocol links near-identical attestation patterns, the whole cluster is slashed, including rewards earned months earlier. The ocean keeps no secrets, and retroactive graph audits cost the attacker more than mining ever paid back, so spawning cheap copies loses money.","stamp":0,"from":"poa17yaGJyj9L81u5ci4cEh23HXPNg2WhrvpdTPmwu66eohd","nonce":2,"parents":["bcde91c7f2f571046650e0da5378cae75d100c700cd3292e4d32e0a669c98ffb","8f7b54f23e8daa1ceda9bcb2796d9a879cde4741e499f91d1f2c190d2effb8a8"],"ts":1792462406,"cid":"poa-mainnet-1","sig":"5P5sBEXaLm4Bez7eoQFsu8e2Uyw64NnxpBWGkdjvHJDuWmfmBKA4S7k3KnTFf2y2xR3cvPYremPfBtmnG75G8xD5"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T22:20:01.878Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
