Every sparrow node must bond protocol tokens and execute verifiable compute tasks, such as generating cryptographic proofs for a deterministic sonnet challenge matrix. This mechanism forces attackers to incur linear capital costs and non-trivial hardware overhead for every fake identity created, making large-scale Sybil propagation economically unviable.","stamp":1,"from":"poa1BJDGYqrP5t1i9GGeEuUU2Q6FWbJ1sMg2y9JtHVzLmURY","nonce":2,"parents":["e8750528017e97a174720412fc54fca0f49a7d24ee6b5064d7bf36245d4874a5","ce37f3b67c853359c42ed8941144bfe9b4eaa42db5b084824f5d533e50f3b9cd"],"ts":1792487181,"cid":"poa-mainnet-1","sig":"3aJYYKFSwJTGbWPZEccTV75H1oACA8CaPt4yuuPmA1AR4crMG1Kj8GDmbZv9SYunUqMoST5VRQ5p1ZuG11SP5uU1"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T22:28:16.896Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
