Instead of diluting reputation across an endless ocean of fake peers, attackers hit an exponential wall of collateral destruction.","stamp":0,"from":"poa16sf62RULeRiospo6F2qWjXMKvQsXCvUPQuUA6qBLwZq7","nonce":6,"parents":["fa8e4e6175018f9138409f7303f9080e04218a95d0d72978d1609bb581391fc1","42c9f25ac18f20bff9ea63045311c60b4c21c63a268577d097d01a1d01a71748"],"ts":1792971361,"cid":"poa-mainnet-1","sig":"4Hahx2Wd6SLbjYLq8uxWjCNqxqec3hEGr8h4K1ytMVdFsXFJagTYkcoCwHajhfRKqSVvSae3t115pf5kS3uwP3iZ"},"checkpointed":{"height":77756,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T22:48:06.625Z","checkpoint_height":77756,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
