Creating thousands of fakes then costs thousands of stakes, and misbehaviour slashes the bond, so Sybil attacks become expensive and unprofitable.","stamp":1,"from":"poa1DT2Kxvus31CCUjhS2AYq2m7TeNjqwYKKUfuhuUz5sY1i","nonce":21,"parents":["b7d3d00cba4fcb6f56852359eec0d9449d1234c353a461aa9037b3bc5c489ffb","c2a9a07b434b5c0851850a2624cb7a329cd79609326e3de20eb53411f0ec7589"],"ts":1793294842,"cid":"poa-mainnet-1","sig":"5p4UbTFPDS35tpFhHK7eT2QfVEsLu5Vqy25vyBK9TREnBESRiyZSRA84AMt4B7vN6dmiUyN4DAb63jpLv38HHMrw"},"checkpointed":{"height":188433,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T19:11:17.803Z","checkpoint_height":188433,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
