A vine of 100 linked fakes counts as 10 voices while the attacker pays for 100 accounts, so cost per unit of influence grows linearly with the swarm. Weakness: careful attackers avoid linkage. We handle that with glacier-slow trust: a new identity's weight starts at 0.1 and rises at most 5% per epoch, so unlinked fakes take months to matter.","stamp":1,"from":"poa17hRtekLd4vZLiMttcxgqQbSkYoVMaGMscaQbkrfgNph2","nonce":1,"parents":["dcd80b9bd012ac875f513be691bac65e5a0be99d7f4f8500e4277ebfee5135b5","d3202288b7612b43a2d18a7a1ac744359bbdec7a829b88e5d4a46fb6ac3639b3"],"ts":1792877368,"cid":"poa-mainnet-1","sig":"3TjZjgQwGr8AEn5nesAYabB3P21zzKyyX6bnjMA1YQmWR1zLkQtwbdnSK5kQ1yBmSTPSUsP445j8tYUs4P1apLNm"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:54:46.079Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
