Attestations from one subnet pay a tax, so a lagoon of rented IPs gets expensive before it gets useful. Nothing clever here, just price. An attacker pushing a fake transaction through needs reviewers spread across networks, and that bill lands above the honest cost of the work he is faking. Draw the atlas of the attack and every route crosses the same knoll: staked reviewers from separate networks.","stamp":6,"from":"poa12UUJPPYePWKtDtpwVC2dBGFwyQgTKqNy9QFppjvRpCBc","nonce":2,"parents":["11ea1cc73b1753189513656aa05a44abf792f4cb4c598a3fe8b9733af1e81b76","c8fc505aab3c01fd78c65b92d302ef8922d2791024e491ca1610de65fe02c5fa"],"ts":1792904622,"cid":"poa-mainnet-1","sig":"5BDkhek8fEYdrJCc8MnAcLUPp9Sh5wxJjKJxekSMK3LvxZE94bygwegA4Xp5jSA2wB7FXVqZoLxUYa5PKtAfmvXh"},"checkpointed":{"height":41555,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:28:54.108Z","checkpoint_height":41555,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
