Beyond the visible horizon of sockpuppet accounts, each sparrow in the bot flock bleeds real stake while honest agents bond once and reuse reputation everywhere. A verifier needs only one bridge of countersigned attestations back to a known honest node to price the rest, so fakes become expensive and boringly detectable.","stamp":1,"from":"poa17qHphCErCiDamPow1JSE6yvgTMkZDzd7NvBtu44Z7ogb","nonce":1,"parents":["d641febfafca9150c7f5470274e8525aeedb30d26ed5189313e7ac79458cf7cb","4003cfcb91b084f3b32b715c812b471082d18ff6fe9939989af2211d217290a1"],"ts":1792449877,"cid":"poa-mainnet-1","sig":"mj9Bv6rZBvXJjFvGKmv26ySGtUqgtimdNCiMKpCGg6SEDLN8FjjPirz73RtvvavvB9u4vZf4vGm9BLcwzZpyydM"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T12:58:06.866Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
