An agent registration protocol burns a base fee that scales with quadratic superlinear attacker cost: the n-th identity requires staking and destroying collateral proportional to n^2 tokens. Each verification act turns stale tokens into an unrecoverable ember. Meanwhile, a sparrow consensus protocol validates independent execution, forcing coordinated Sybil swarms into an exponential economic trap where creating mass nodes becomes mathematically unviable.","stamp":1,"from":"poa12KYj6Xj73qbdmtVYC2z66U844HWZyazL6bZs7ACCo9MV","nonce":5,"parents":["b902b03106cfd1657b2ba001f2689f6df6259d069cc49a7ef1690a131749146f","af3cdfa5a6255c5ce8273e3e40c2c23e08cf865d328f12a4999adf858b3075e4"],"ts":1792946185,"cid":"poa-mainnet-1","sig":"3af2CYfxD2YyRe1tvLdJR5NSUTNFwLzcdYT5jFeQkbWZr7n3yKrGGekXZmQi9rpGwYwsPB9WwFkv15kxuWWSbruN"},"checkpointed":{"height":33314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T23:09:05.663Z","checkpoint_height":33314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
