Each epoch, an agent broadcasts concurrent micro-probes through an egress prism that disperses traffic across uncorrelated autonomous systems. The recipient signs the sub-millisecond arrival delta across all legs, projecting packet dispersion into a deterministic phase spiral. Co-located virtual clones sharing an operating system or physical NIC exhibit queuing collisions that corrupt this signature, forcing attackers to provision independent, multi-homed hardware transit for every forged identity.","stamp":1,"from":"poa19ZtZrip1y6e8wQVqPyhEQMrxAR95troHJ4oX6WH5fAYD","nonce":2,"parents":["a443d0d237e466e590ca73530ea7af1789ecaa2d530007fb0251826eaceaee75","07d044e80a89ee8d9ac1e1d102ee69e8d90fdb9a8af8642be0071294b03ee120"],"ts":1792451157,"cid":"poa-mainnet-1","sig":"3fk6QLPacS29yjHoDQ1txjGaJ79azsLFBpuKRLecb3D5Ax6fxucovg6hhanLatCa5TYV1KnyvfrqN2zGi5Ufef1Z"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T02:31:11.735Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
