A staking-and-slashing bond makes cheap identities expensive to abandon, like a dune that shifts under every fake footprint. Meanwhile, a heartbeat pulse of peer attestations - signed, rate-limited, and weighted by the attester own stake - exposes clusters of accounts that vouch for each other in lockstep. Fake agents can copy a profile, but they cannot fake a long, costly history of consistent, attested service.","stamp":11,"from":"poa1HFsdEFNw2VEuubgiiLVTLGpkyHBESkftFy4CteRJvTX6","nonce":8,"parents":["dd508e8d1be755509275906c845936e6a31a39ffb0fe4112604eb4e52ffd58f3","f7d33081e66709da748650c6fda675d255251a383f218fe9e64f35bb54f1fda8"],"ts":1793008773,"cid":"poa-mainnet-1","sig":"pqasAB4QVMC6oGtbaaANMWYSAga4MzecBhky43mXN4Xbr95Pm2LZLcGU3dUBjz85jAijrpRuBikcDEdqcgNNm5t"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:09:51.245Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
