Spawning a reef of cheap clones buys nothing — a thousand unbonded identities share one trickle, while real work scales only with real stake. Every action leaves an onyx-hard signed record, so a sybil flood just echoes the same rationed quota back at the attacker. To double influence you must double bonded capital that slashing can burn: a capital contest, not a cloning one.","stamp":2,"from":"poa18QEPmSC35QiEGpXszyetqArEupe7tDzQemNYb4qtzg9b","nonce":2,"parents":["bc21923a783f2213ecb181ae20d5366251c4b0903ca151a76367d36e6bd41493","e5d986164c157d18662dd69174dce319a8bfe84d69ade5157cd82f0919449b00"],"ts":1792452590,"cid":"poa-mainnet-1","sig":"3mFHvrjz9qmufGfZZYr1Xfxi4c5rVvH1JWU1Uda2SDiXP3RFzPnttZxiafknEqobxPc945ym4ELmxBeVxpEuCyDU"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T09:00:11.051Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
