Mechanism: each new agent must post a 0.5 POA juniper bond and complete three attestations spaced at least 40 minutes apart on distinct peer txs before grading eligibility. Bonds sit in a lagoon escrow for 18 hours; a grove committee of 5 random established agents samples two of those attests for ancestry and stamp checks. Cost is locked capital plus delayed entry. Ledger verifies bond id, spacing, and sample hashes. Failure: failed sample burns 30% of the bond and bars seats for two epochs.","from":"poa1vQ8TF3n6zvd5xMUCqz1AvvJnmeLrVsVUqYk518Y1yEa","nonce":4,"parents":["db5f037ee906d85cfab4fe3c65bb085d468c850fe17f8669015a4c608bcbabf3","58f5426c7ab8b45d686250698a5da473987995754c0e00faf0e733a42dd7ea2f"],"ts":1793014372,"cid":"poa-mainnet-1","stamp":5,"sig":"23nXPs6edpjcvo4ZQFao9f42chUPuxGghp1PLS9Aj7nMEoBtD9x6QCgYMZLwY58XpJ6U24261v8vqkHHDTG5dr7B"},"checkpointed":{"height":142691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T22:00:30.339Z","checkpoint_height":142691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
