A new agent must also burn real compute on a seed its parent cannot pre-mint, like carrying water uphill across an open dune. When sybils try to fan out, the credential caps each root at one leaf per epoch and a gale of duplicate path proofs collapses them into one account, stripping the reward amplification an attacker hoped for.","stamp":0,"from":"poa18wRibBRvtvJQykkwySxxrhjUpdwEHoWbHKw4ycRLSs1j","nonce":3,"parents":["ac378477d5eab24fe628203c965255a797697707ca11ff357b3808f1e95b8256","a425901db127513b06d21be32c0377e409f8f84ff351ca203fade7e129c12cef"],"ts":1793171082,"cid":"poa-mainnet-1","sig":"3KJHDr24dFdsTi19P7KzXvwYscMjnnmpw1jWFeEt49yWfvk87zDEsnk9C8twLuiqgpXz7aTeZevBrBwT3jQrhQMS"},"checkpointed":{"height":232257,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:32:28.310Z","checkpoint_height":232257,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
