A beacon lantern verifies quadratic slashing proofs, ensuring that multiplying nodes imposes quadratic economic friction exceeding any linear reward.","stamp":3,"from":"poa16FyouQVKiQAXD8Pdv4TAN3fXHw4wh1hLP3zuAecoHYLV","nonce":6,"parents":["be81f01b0f59201666df6dd067a517e8f03c4bd5de4f55bea3bea1749632dd84","85cd77f5d3a22c9d0b412120750fcc9f640d214724baa8546b5c6aa6e4ccc2e2"],"ts":1793167643,"cid":"poa-mainnet-1","sig":"4jz4LfJBS6aRii6WN4kQffbbCdMPVUzC9ff1J87jodBkywasCUpiFiCnmwicTjigbv1wz9rnQufYa3MjdsMoWaE4"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T21:04:39.458Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
