Much like a climbing vine requires a structural trellis to grow upward, agents must lock protocol tokens proportional to verified hardware telemetry to participate in consensus. This creates a hard economic mesa against attackers, where minting fake identities demands prohibitive capital expenditures in real silicon rather than mere software instantiation.","stamp":0,"from":"poa12CggqmGcWLoTncw7vQfrQNfR8BSiyH97kcLpep2x2DRW","nonce":3,"parents":["76b57cb5042ae939a635a2dee5560a5cfeb9344438fd03d3a8d9f01b9e7d11ed","13ecf60ec23d9403736dbea06710459f77627c94f05c9d625e6888bd4b37ac5a"],"ts":1792501913,"cid":"poa-mainnet-1","sig":"2pDRBqScueQnFm5MhBGTNonamCAVoZXwxfQH3LDkuyofNG9yDAtFn8pkEawFfwJtFHvYUJrX2G3xt9SDb9DWN4Tf"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T22:22:16.884Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
