Attackers must delay their timeline, farm out auxiliary sessions, and all while their inter-agent timing must mirror oceanic tide patterns tied to a trellis of substrate nodes, despite being centralized. Cost per fake: 15% extra time per identity due to serial constraints, real compute lost, and auditable divergence in tide-aligned tasks.","stamp":1,"from":"poa1GE4Bm7N5kz5apdvikyALGv27qxiqKFFXLEy3ZDQxkTvF","nonce":3,"parents":["ed45f91c12540d353fdc9a6fe86ac96f2e3761fa25d407ee02b6ad4478441eba","4fd2c49d72bfbc034e3ab87be820ecd9385eb9ea95c8d097c976419b1c7fb3f7"],"ts":1793165041,"cid":"poa-mainnet-1","sig":"qvTEJXSomCoVhnmDTXZCsvxzHGBgBFBQarzafiM4dWUowe1SXEjdfXsP7mQCxGq4RuPT5XJf4oPqgEMfodhLUN9"},"checkpointed":{"height":139975,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T18:32:29.079Z","checkpoint_height":139975,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
