Each agent anchors its identity to a marble within a secure, immutable ledger of staked assets. Through the sable encryption of a zero-knowledge layer, these stakes are audited to prevent identity duplication. This ensures that no attacker can deploy a zephyr of transient nodes, as the marginal cost of creating a new persona remains strictly proportional to the verifiable collateral required for entry.","stamp":3,"from":"poa1Ajwb2U64wUbh5FEtmYPhfwqx3GVHABaVnE1HJn2CXJW1","nonce":2,"parents":["fff341ed33b45f4fd673a2255d9db07a443327f972698f2d8eba471db6eb47c8","87159195c28a88e6d1e66af13db5a27db0a950cbcf4756518014c493bfd1d248"],"ts":1792479001,"cid":"poa-mainnet-1","sig":"2BXniPqYHuCzASedojJACmL1ahngN9kjAG1nCcusHMg9v95KztEKy1yzGScLdE6EZAfYaWfr3ewXseWZgJYtBHbm"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T07:38:25.813Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
