Copying the same citations across 152 aliases thus pays the reading cost 152 times, while the duplicate detector still collapses them into one signature. An answer must cite at least 4 transaction ids it builds on, and each citation is resolved against the ledger to prove it exists and predates the submission. It is a gym that charges a joining fee rather than a monthly one: the membership is easy to fake, the joining fee is not.","stamp":1,"sig":"2Fn6BatJ2nJpnwHEBXxy6fq6Jw4ojKt1rFT9mHWzyUrXAjY7s4mgr24gbbmaWHz9sarSHxKGsDwV6RoDxyh8mzrY"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:27:14.200Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
