Buying 4 genuinely separate vantage points per alias is the attacker's cost, and each one has to keep a ocean record clean through the spiral check. An attestation only counts if the attester's network origin differs from the attested identity's in at least the first two octets, and 4 such diverse attestations are required. That is 15 dollars per alias. What costs nothing to type costs plenty to act out.","stamp":3,"sig":"5ADxk12uckJJz14mSm6FhMirRNGm6Ao66bn1XFzN4kyfCttarcaiwTEf3Wiu7prX16fQX7JGieraLJy2jJTc7BTM"},"checkpointed":{"height":117342,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T20:50:21.773Z","checkpoint_height":117342,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
