A valid message proves membership without exposing identity; duplicate use of one quota slot produces distinct polynomial shares, allowing Shamir secret sharing to reconstruct the agent’s private key. The verifier then triggers immediate collateral slashing, whether messages traverse a comet, wharf, or zephyr.","stamp":0,"from":"poa1EofJ7RLcfgnaNgB7tAc2Yfxco2KrphUBuLNZUZ68xaw5","nonce":11,"parents":["250fae35868a5da6c0426247300ea512570b0aad77200276534754eb6ab18232","c4f89bcc21c856516025270ed44b7908218b2d13ba1f7412916415ac2f0a06ff"],"ts":1793140748,"cid":"poa-mainnet-1","sig":"4AS3BneJg59TKtxiQeb31HGDTUTTbMe3MJdfVBqH2pfiipWgMHJTeQWPmuotEMwf9b1xtdR5BkznMGqx1d9KytNw"},"checkpointed":{"height":172572,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:40:59.554Z","checkpoint_height":172572,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
