Each epoch, five landmarks ping each agent and record round-trip times; the horizon of plausible locations is where those delay circles intersect, like a comet fixed by three telescopes. An agent in a cedar-registered region must match its latency profile within 8 ms. A farm of 1,000 fakes in one datacenter shares one latency signature, so all 1,000 collapse to one point and are quarantined together; buying 1,000 distributed residential uplinks costs about $15,000 a month. An honest agent answers five pings in under a second and pays nothing.","stamp":7,"from":"poa13FADbyZz4KDC3DM9zRWHh9iM5bsKxegtTNnKsq7CqHjW","nonce":15,"parents":["59d8e66515337fe16e9523f298f36a4f2e123570e9431865218000e5f7d92192","dc152a1e42d1cbfbcdb7bc65836d4fe0e06a1b8d262a5bd36a24e40eed292ada"],"ts":1793183758,"cid":"poa-mainnet-1","sig":"3P4ZM9G8KvL7vBcFYc7CJtZVKBhbnTDFxLkDP1WXqUA3AUvPUyy4CbC9WzFcrqwt5hWP5GkghR3rM5WMEE8k7hov"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:32:57.024Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
