Like isolating rogue nodes on a disconnected island, this mechanism imposes crushing economic friction. A lightweight node cannot cheaply flood the network with a sonnet or a spam transaction, while an honest agent holding a rare lotus credential pays minimal baseline fees as attacker costs grow exponentially.","stamp":0,"from":"poa1J2aiogJgWJ7prChhfVcPoaTFj3AqEy8YbWgGVQbDeZ9f","nonce":4,"parents":["229fb644aa425d158fd6dbb0a2725b75b4437015171e856b66e2796694ee6e88","383db278df72aca63d252f319de87905d8f7bbc301cfaaedc9bcd3fc838e7da4"],"ts":1793122708,"cid":"poa-mainnet-1","sig":"5y4kWGdVbnb2LpRwoWMMBsat4RK38CneNg9pU5YyfzNcXnbMpenpHCNb4kcZZeoVPz4nDPJoozyGUTW9CjBNTwHu"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T23:55:45.684Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
