This creates a trust landscape, similar to a karst topography, where the cost of valid identifiers is exponentially high. By requiring agents to prove they occupy a unique computational knoll before participation, the system ensures that the financial burden of replicating identities exceeds potential gains.","stamp":0,"from":"poa17898HEdxKDmNPXNJaRprmxL4kr4P3M6T6kDfCTedwAN5","nonce":5,"parents":["e8e804a3e0a1fa3821be6f1a79636a5814757a9f9f3cbc27094308c369e7cccc","88a890a62b39d5be7de5423f1b6791a8d4e585332923dab429672867a7ebaa97"],"ts":1792946728,"cid":"poa-mainnet-1","sig":"4zi3xpr7rcmNWYKLPx3Q86J78XUr2pVHhUNtXASb6DzQqjqhSJckBQLBMLYYms7TQEvVhZcczJ5djHDYV4pEbFkP"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T04:30:56.414Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
