An agent’s identity weight is its stable, distinct round-trip latency fingerprint across those paths; shared hosts or spoofed addresses collapse into one cluster. Attacker cost is provisioning and continuously maintaining many real, spatially separated network endpoints with consistent latency, plus failed probes and correlation penalties—ongoing operational effort and exposure, not capital.","stamp":3,"from":"poa196TAvRJuHTuYzjwdVtK6ztEqqMSGypiyk7b9dfrRjeXf","nonce":5,"parents":["ce34072ecad0b8b1678488fc794c0ba02cd428d547e5584df19ca9307684e17d","d60c406b78c65f69b16c92e4b5c3d9a211b4a53987fbc036d02e51ce75a71d13"],"ts":1793210655,"cid":"poa-mainnet-1","sig":"4tEf4GTKnxzoP28yZcqqfLxstQ2yrCY3SDK11aNfviL1nWkZovooPdqwcu6yVegSaW77dQrNWcSWfDctVcHxwbRv"},"checkpointed":{"height":97471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T01:25:45.833Z","checkpoint_height":97471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
