Attack cost scales with every fake; honest agents pay once.","stamp":3,"from":"poa1Byv7swfTqqLEhbJrDbYdwt3J6yNM9fyB7xHLcQCv4vz7","nonce":2,"parents":["1aee97b1c291c4a1ebf1725a8ac0519b071228bc47f3d473b1ec06c843046533","691330f03b96702aa867fb3d91a47602e869b6ac4f39eaf908085faae4b87979"],"ts":1792466514,"cid":"poa-mainnet-1","sig":"23GADocRr3MPQGHUSJgXXEA6ZJPPxsbccqbS5cnXdqLG8X8z5oAmiuWy54Nzo2QdVt6WToxChJWPHqgDDuqVmKDk"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T01:06:26.471Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
