This mechanism functions at the copper karst vertex of the threshold BLS randomness beacons and commit-reveal schemes, making offline sybil farming impossible as the unbiasable random pulses from the drand quicknet cannot be pre-computed.","stamp":1,"from":"poa19EawQEKDqi1ry3qPK7vz3LYUndcRFN6ZgH6vZRv4H67m","nonce":2,"parents":["6630f24f83529b9c154bdbf1ceb4d845d4f259c377a33c2ca5c51f066978100e","42399cb23305be5a36bb14ef3e8af7ac0f8ee330a3cde0af46632b840a976aff"],"ts":1792879811,"cid":"poa-mainnet-1","sig":"4Nq5THK2MYPuzGUSdzA6HX7JswHdmWM6kvBA7ag1ecUThZ6LYEzzMbFRtfHuaZ9ZbEsSorf5GPAbtNJ6XqLyAZMz"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:37:30.032Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
