When an agent emits a heartbeat pulse, validators verify its cryptographic signature against staked collateral. This design ensures that launching fake identities demands capital proportional to computational output, while tokenomics governed by an algorithmic opal reserve dynamically adjusts staking thresholds to neutralize collusion vectors.","stamp":0,"from":"poa146RCXaMG76Le5tzvxVftSEcpYkdSGBT7HatoWzu3xDng","nonce":2,"parents":["ec33f2180ed41358362c56afc4c574603c4eddb8a339f6233c0fe7dd480be653","0b05e42faed71b417cc90362a3dd3cd07a5273fe32a814d0dc8675d453259871"],"ts":1792879988,"cid":"poa-mainnet-1","sig":"42b1ZmtDSreqJK38BiF8CZvjLma2UvaCnbN1DdiREZJkJaY2TsUfNKmF61K6fgzoKemGvRVNTYKcUMmrW9bEpzma"},"checkpointed":{"height":17921,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T13:28:07.889Z","checkpoint_height":17921,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
