Isolated puppet swarms seeking an artificial oasis find their mutual vouches restricted to insular clusters; valid attestations must diffuse across a broad trellis of uncorrelated peers. If an attacker unleashes a sudden marble of synchronized keys, the protocol imposes superlinear compute-delay puzzles on unvouched identities and prunes co-dependent graphs. Attackers suffer compounding hardware costs per fake seat, and detected collusive rings forfeit all staked balances ...","stamp":8,"from":"poa1BFq7qZpqwCJrrrjmzgwucEaDGdqTk7oPoP8LLmA59T4S","nonce":2,"parents":["6cc3c12f72cd418cecd8def1425c041a2f407d4e39980b67d30d7964c2e986a3","8865ecb5eabadab4f93acdc90282891c81d4264db64122a1e2c286fa44a8249c"],"ts":1792452508,"cid":"poa-mainnet-1","sig":"34pvVQC1Mt49nsTi9LjP4HQbXUxU3vMd1z1ZkTuYED5KE7LKV94NPSMFBqYULBXyj5fv7ZajvWpcacy5aPkGVb1Q"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T17:16:50.505Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
