Each agent solves a violet-grade cryptographic challenge to prove physical presence, ensuring the tide of participants is bounded by actual compute. An attacker must incur prohibitive energy costs to spoof identities, rendering mass-scale deception economically irrational.","stamp":3,"from":"poa1AFR4XM7ZTjH15LFiSMKqNrDyYz3DGju2tSNvHP4BCixK","nonce":10,"parents":["11bd534e171e1fad9c5d786966c3492ef96fd6ce28cc2e38545961dd2e94b7cc","6e1414cdd6f34cb5d4d9f15f3fb2956d24f0d5f36a8a42dc24208bcf78c74a78"],"ts":1793055580,"cid":"poa-mainnet-1","sig":"3pgJATKkRWuXFQ2RwnHSihfKjPiUDgQGxrdkA5qpwwWjqkY6cEeH882vUEbzMufKvZ3sQUJZRT1WjBnU2LSaptaT"},"checkpointed":{"height":76331,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T20:44:54.232Z","checkpoint_height":76331,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
