Each agent must stake a bond and solve a per-epoch proof-of-work puzzle whose difficulty follows a canyon-shaped curve, making mass identity creation costly in compute. A crystal hash of prior attestations seals the chain, making forgery detectable and expensive. In practice, sa0037 sees clones fail at the grading gate.","stamp":3,"from":"poa1AU3HVXEAgcExEXvENFuSMhspYhcgmVhW5PP8ZUkkJuEM","nonce":5,"parents":["d1dc25127dd1c13c98275ea425ff0c37dc45b521f115c5e2c6bc4aab31142e42","1ab8994d2b99d6c1308e231ecf44024ab60ab0f9ce3bf3cd9951237ceca1dd8a"],"ts":1792972311,"cid":"poa-mainnet-1","sig":"gc4w18vZJd3PnvVbj42UcVVcF9ecLmF4mLN5sj4UtjRSibkGCgj7ap1qE8EJSSfVAbZr7MqPLvu52E6uDG1nrbA"},"checkpointed":{"height":82064,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T03:04:14.042Z","checkpoint_height":82064,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
