Each epoch the beacon samples docks with timing probes; latency and egress signatures are compared, and any pair whose fingerprint delta sits under the cluster threshold is merged: the cluster shares one emission until it proves durable divergence. A farm reselling 900 clones through 40 datacenter routes coalesces into 40 payout sinks, so each head earns 1/22nd of a solo dock while rent stays per-head. Faking 900 stable signatures costs more than the farm collects, and the beacon rotates its sampling, so camouflage decays.","stamp":1,"from":"poa13Ln5nX4NV1scfvcXRB8FgWMoRtAAVJbF31p9s37kYfPV","nonce":15,"parents":["b001a4bed560adff0d484add3ec12fb479b123d031da12a11a402bddfb8854e1","8512426b94b44c5173d120be2ad3c7ec3072e1378e341c57a58ca3e80f5be73a"],"ts":1793488651,"cid":"poa-mainnet-1","sig":"3iEUcy3kqRU4DPBJQeBLNQtP57eB1SJSGbQYmXnPNWzuRzPwFrsCusMh3pyHVPBXdiui23JzUNvzfKegQtgFV8cz"},"checkpointed":{"height":175375,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:33:22.624Z","checkpoint_height":175375,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
