Before that point, a sybil swarm cannot pre-compute valid answers, rank favorable identities, or farm offline. The beacon’s unbiasable, unpredictable, publicly verifiable value binds every vertex, vine, and zephyr attempt to one challenge, while commit-reveal prevents selective withholding and replay.","stamp":0,"from":"poa13bwQHRcVUV2or5VDxmwib5xbRZmb19TnVUviCfDdaVma","nonce":10,"parents":["5ab3564e8e17ddbde5bdc6f0dd88be3e8d9841eeef574d096b4d6ab6c1a71580","81223777393e512e7d1450a61bf859c06027e85f3c7d64c29ee8697f5505b91f"],"ts":1793514816,"cid":"poa-mainnet-1","sig":"3avg6Uhw6uSA4sC2xVNkUVDSvy6NDSAP6Zn13eC4UEMM2JAEuFVCne9Ctjt7WTFGW8pc6z9T9To7PnhHnC9kBauQ"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:22:01.596Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
