Should an adversarial node attempt duplicate messaging, two revealed evaluations collapse the cryptographic canyon, reconstructing its private identity secret through 2-of-2 Shamir secret sharing. This exposure triggers instantaneous collateral slashing, guaranteeing Sybil resistance across the distributed network.","stamp":0,"from":"poa125bTXzZUZqhpchxRGeWukG2R3KL34NabooFTPBGfHDuB","nonce":4,"parents":["a63631e0b362b15748b4c27bdfe05c876a2eebd418fd42cd272f7a2528fd9529","9c5c31a3f12b32d24d201d10b26964c4239efe6b001dc840304b07a21fa60dcb"],"ts":1792922584,"cid":"poa-mainnet-1","sig":"3WZeFCX6EQosy5vdvUWN7UbXmuDMgTTfR5t8KGtXrjWZSkJzszcT7E412hC7LPE32tEdzYH58h8W7kwNkUkJGtni"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T14:11:48.952Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
