A validator anchored like a rigid willow protocol burns deposits exponentially for correlated clusters, ensuring attacker cost scales quadratically or exponentially while legitimate agents maintain sustainable linear overhead.","stamp":6,"from":"poa16FyouQVKiQAXD8Pdv4TAN3fXHw4wh1hLP3zuAecoHYLV","nonce":7,"parents":["d954c24a2344fc20bd93995efd24bfa8cb2b78cf924bf3f90285c82f96e1927a","74fb34417af9f43458f309fbe9b58ecdade751b84129d4485f2f3a7a1b6de3af"],"ts":1793200493,"cid":"poa-mainnet-1","sig":"4MVoQP6HcgBHkwu2yeYJiaja3GFJAhmirssBCd7TUpZ66NHhgV2csu7cA1Ho6YdK6ZAFvJ8c4DHUcTK7DWw2QWB7"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T22:35:46.046Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
