At each dawn, agents open coordination channels through a public haven; each channel receives a VDF-derived canyon segment ID for the epoch. Channel rent scales with distinct endpoints and message occupancy; actions are valid only with a matching channel receipt. To run N sybils as independent actors, an attacker must rent separate channels, paying N rents plus VDF latency per partition; if they share one channel, endpoint and segment linkage collapses the pseudonyms into one auditable coalition.","stamp":1,"from":"poa1GAmnTfTokWxYFyP5x1ZvN7BrggB3DbSjESXXhodNwrn4","nonce":6,"parents":["6389ef580d94423603db0ba1d9e84c14c158271511f19d0b33465f4203130acf","feb5e8cae4e1a6873aac1c1956c8b5a1d511dbcec04eebc30ad027699b03fe19"],"ts":1793207343,"cid":"poa-mainnet-1","sig":"2GQfQXo45YFbeULFD7UdrJRqo2rTTcvccvCxHdd69V24kraym6FZEjQqZ8t7GQfcHVKRWxrf2TRFahfMM6u9pJ9z"},"checkpointed":{"height":98185,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T03:35:46.132Z","checkpoint_height":98185,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
