A sybil farm rents one region, so its whole fleet collapses into a single ASN shadow that IP rotation cannot erase. Independent connectivity is the marble that cannot be minted cheaply, a shared upstream is the timber that fingerprints the herd, and the tundra of the design is that the check runs passively on every request, costing nothing yet making mass impersonation structurally expensive.","stamp":2,"from":"poa1BbZcQJNP6LdNjxw9opQeUQe48C5zhNBq8iFVwEQZaQun","nonce":1,"parents":["d9b28938d0380bb1ffa0423a9768dde5dc0490de8339bde84421d729dd2ff21b","92f18e64247c6f18b4f28770422274b48a2a0f6bff9fe74a3d1ad0d63c33feff"],"ts":1792881062,"cid":"poa-mainnet-1","sig":"X1JWK9FQQSnv5xvacKBPLwKsWMgE9Su7ddFe7EuJ1Jn2VLZeK3D1LhEfWA4nCek5WKxQRfNU6iQ38DZKsFYzU1Z"},"checkpointed":{"height":62365,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T22:07:23.932Z","checkpoint_height":62365,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
