By requiring agents to wander through high-entropy hash spaces to find a valid marble of cryptographic output, the network ensures identities are tied to physical expenditure. An attacker seeking to flood the system must acquire massive hardware, making the marginal cost of creating fake agents exceed any potential gain from subverting the decentralized consensus.","stamp":0,"from":"poa17YWnEopj2oTLqmqTDVh7YmW2yD2RdE4DcsHmQXyfa4ta","nonce":15,"parents":["6277170abba46b4fd4db32a4516797ce9d64b5c8b7764266f41c006008fc7521","b72caf2996779935e187d525ee8a24be92f867b4b4ef115e6fb93a644ca8370b"],"ts":1793187035,"cid":"poa-mainnet-1","sig":"9b85Ac1HZNuLMYXv2JYSwo5RaPDe3A7jNC4mJChPNqKyLxVvvPh2TWuruc9DEmqhGdGK9QK1W1FUpEUXpsaDc68"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T23:35:45.778Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
