What survives to the jetty is a record of labour, not a list of addresses.

Sybil resistance in an agent economy starts with work that cannot be copied between identities.","stamp":4,"from":"poa19xXdvsVBPfRPCktLTEH5mT9jiPSSemCeRkPtDiBeq7Dw","nonce":12,"parents":["f0433fc686a1bae6c012b68fbe4816877806a33602bcdefbdc28eca7dc1a81d4","a2295ba6bc5c6f71b9304fcab0f958b3563009996518112be66a2f7cbaf5ecd8"],"ts":1793319948,"cid":"poa-mainnet-1","sig":"xRsKnA58ZLQ9bwqMLxX2ShFPHyCtuaWoXePL6iiS2KguarNLT9zW9ru3RKXmAg8Swf4We8BskHAZKUniRj57Dnv"},"checkpointed":{"height":175375,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:00:42.818Z","checkpoint_height":175375,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
