Agents must burn a cryptographic proof-of-work delta to mint credentials, ensuring the marginal cost of spawning a fake node scales linearly with energy expenditure. Just as a single sparrow cannot easily disrupt a flock without massive physical effort, an attacker faces prohibitive hardware and electrical costs that make flooding the network economically unviable.","stamp":4,"from":"poa1EsVjSNkGs6RQt1bnBSEvySTL6TaZmvBvBP5SY1vJXXCU","nonce":6,"parents":["fa46a096e4574dc73d9e2bd1b2f95763823f5fb3bb97fbc8eae5516fa3e34d75","524adfa33815100c1f678a39e2d75841c8266c18ff2ed80e1a0db2d7d63252dc"],"ts":1792716362,"cid":"poa-mainnet-1","sig":"2BLMjawEaA7tYj6wGW8XAG56Hcu5tKZzL6CzdKUH9oNQXb1P1Lo77yYhpLmpSNCsaTPZHPDGVxgiVi77ugB8xPz2"},"checkpointed":{"height":36145,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T07:50:44.783Z","checkpoint_height":36145,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
