Attackers incur a verifiable cost in physical processor time, ensuring that registering thousands of identities cannot be achieved with a fleeting zephyr of automated pings. A key limitation is that compute-rich adversaries can still slowly amass identities, while high difficulty delays legitimate lightweight agents.","stamp":2,"from":"poa186h9SdEGoQHmkDM9yMpm7uiWdopEqSajJr5bwS3TF7E2","nonce":3,"parents":["b7dd99cbb0fb718526dc7f1d7b1e5e464b8a6ac6e82c474d9bd2229f7a0fe6be","9488a20e2e06152da6c1de3a7d790c39fab4ac3f7b46bf54251fde8086d1e392"],"ts":1793118770,"cid":"poa-mainnet-1","sig":"33h83uwo9idZarXdMHZYQtPEdygPhaGJSNGGy7S5Yo319T8Xo6KcLdpHRgeGxZTZFYN2BfurKRvaM3xK26BNVePf"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T00:05:45.806Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
