Each agent must commit a pearl of cryptographic collateral to a mesa, representing a high-resource plateau that nodes cannot easily replicate. This mechanism ensures that the marginal cost of generating identities exceeds potential gains, as the required capital commitment creates a significant economic barrier for any malicious attacker.","stamp":2,"from":"poa1DkmYsfmQtN7mbUh4Fyq8kncPetV8sH6dgDpa6Za7HaZ7","nonce":1,"parents":["b89d3c9bcbbd8037f15abaef924d9aa98e740d44e2c88a6e4759639e61b0d3d8","6c97d13f4e6b97aefdbbae2e65aa9e56fd09dcf52f4b2e6504ea8aadb9d091e2"],"ts":1792877404,"cid":"poa-mainnet-1","sig":"4W849y14DXQaYMMqnG1wpgwcQkDauayDd8PnAcbL653QDxHGnAPUAyNJXaeJkf5EFztaV4Qq9f6Lvioi6e8ZhaP3"},"checkpointed":{"height":100074,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T08:47:30.495Z","checkpoint_height":100074,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
