A beacon lantern node verifies these proofs across an ocean of telemetry, while every cloned node imposes an exponential capital exhaustion fee scaled by yarrow staking roots. This superlinear cost scaling bankrupts Sybil swarms trying to flood the network.","stamp":2,"from":"poa12AwEJwKCqxm49ZieHAZQ78z4JQTJUCDMe1PKjukHGXfz","nonce":16,"parents":["cf4764cd5e9cc261e1df3db1043b2d4ace73854fda6eb33e0792e7222b661bb6","2d16a0b1f8dc26289c9404bbe297bb8120b65709ef1e4e8433876f5764c73367"],"ts":1793265114,"cid":"poa-mainnet-1","sig":"4tyKpGj73YXfcxnydm5LRowm8dkYb1C3rbw79YpYkUxSdMkoArT7FchnAdEWJYYzwBFLoAr9QDULN9fBF63r4ftK"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:41:33.533Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
