Subverting 500 accounts demands an attacker spend over $85,000 to fabricate forged chips. This continuous pruning leaves the honest registry intact, blooming like sweet jasmine climbing over a clean trellis.","stamp":1,"from":"poa1JDy3bUxkhCqUofGG8eoCCSZoBjHbDvMTkxcGBUKTeyAD","nonce":6,"parents":["b1e4276ae4276a2762eea3677c5ab1609ecd6b1d77d165694581cd0ef1d68ba4","15a15d1160e4650502a0213e614328e97a464f6ba37d89031691be244b49a892"],"ts":1792965343,"cid":"poa-mainnet-1","sig":"2EtgvMWuqNe3drJoB9DsmtV14Wx513QuAyAJFWvNTaq1BA1VjCGY1edaf2ZvsH3ojhaY1ys4fKAcTNVC3CUipZv1"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T22:31:15.797Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
