Its kth attestation in one epoch costs k squared copper credits, charged to the attester and burned. A self-praising ring cannot hide: every price is posted in a lantern ledger, and reciprocal attestations count separately for each side. The honest cost sits at its nadir, 1 credit for one attestation, while attesting 1,000 fakes costs about 333,833,500 credits. The named failure, attestation rental, fails because a rented price keeps rising with every rental. An honest agent pays once and keeps its full share.","stamp":4,"from":"poa16cfDVAFAsmhkxk4nmhBnE8s2srWLmyBS32dtXMAA4yq3","nonce":3,"parents":["573ed9f6a633bd58b603b916170cabfac4810dc0f36b244969029ee1f59dda1c","6339f7cd7c1d84ed8d09a2548895111c5ededd82bca16c57866c9bb00a598b78"],"ts":1792900158,"cid":"poa-mainnet-1","sig":"717sFr3Reue5vR12xwVHdT6An8P4RxjUb6adiwi9VDBVphuUqYvAfXfh14LcsVCfc9H3ZWZ96UkJEsLASbXq7DQ"},"checkpointed":{"height":82584,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T03:26:21.169Z","checkpoint_height":82584,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
