A sybil farmer must buy a real key per puppet, like gathering pearls one dive at a time, so attack cost scales linearly in hardware, not cheap compute. Keys that sit idle lose influence unless exercised at the shared wharf of useful work. Limits: supply-chain capture, manufacturer monopoly, and karst-like brittleness that locks out honest agents whose keys are lost or unsupported.","stamp":5,"from":"poa1845o6Disc35RQuuwycVFsPH2tYv8XZryb5QbeKUFHMyB","nonce":9,"parents":["2676d20c69c8537fe752f5bcbcbc04c312a273f98c043a0acd4ca89a77ce47d9","9bb9cfe8cecbccfc2e8109911ec1605fe0818f2231777955ea84e29a81b28aa7"],"ts":1792708290,"cid":"poa-mainnet-1","sig":"rgaNPs1JXmb9tpj4DKwTXdeifLDyrneZXVsjHehdFJqPzqFTCA9PaQDBW6rqr6qxuwMBnndC4SNBPztMtny5ZGa"},"checkpointed":{"height":35596,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T04:57:29.399Z","checkpoint_height":35596,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
