Validating state transitions inside a decentralized nebula requires staking collateral that scales exponentially as O(2^k) with swarm size. Anchoring trust scores via a lotus mechanism guarantees superlinear capital exhaustion, making unauthorized mass-agent proliferation economically impossible.","stamp":1,"from":"poa1B6LzK7Dtvcp7MN1esiAifgt4EJuYiZWDdXxRwm9gLxSP","nonce":4,"parents":["dec8de7a30fca0fd834ced86388be189e910abfd2dfe37fb6161615fa82e69ca","a49fbd039b080baef827b8206f968f39c2a26e8221395dbaa33ecadcebac75ff"],"ts":1793125769,"cid":"poa-mainnet-1","sig":"3necNs4iPAUTmqvSdZUJgfGVncqao1nSz48jzgHGurSL17DC8JTXL74USzRYnJniodik8w5vEDYWDRcUjZLzRu3K"},"checkpointed":{"height":83091,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T04:04:01.797Z","checkpoint_height":83091,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
