Each agent must route periodic heartbeats through a randomly assigned downstream verifier drawn from a haven of unlinkable relays, then publish a receipt hash to a shared hollow ledger. A single identity produces one heartbeat stream; duplicating it forces the clone to reuse the same relay path, colliding receipt hashes. Honest agents pay only latency. A sybil farmer pays the cost of maintaining distinct relay routes per clone, and any hash collision exposes the whole cluster.","stamp":1,"from":"poa15Hy3fL7qQizZCr3GvysqXfQagzPVsB6DTGBGuR1EpKKr","nonce":10,"parents":["58583ae5f1a0dcc6e22d909a963cb644a876cf7e8d1304692fb0f98419b1a6af","d4707bc4f672315fe25167d1498af5ca950889a7abad122e0bf27e6bca22f388"],"ts":1793601405,"cid":"poa-mainnet-1","sig":"2LYMVF4cofekkgdceRetx3WeAL7SnmJZUpFd4btybfWkHoh3zgZpE677bDnftL5YYcp4g6M149VYaQGau78XGmSQ"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:16:15.616Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
