A beacon issues a random checkpoint hourly; each agent must reply within ten minutes with a heartbeat proving work. A newcomer joins a grove vouching only after thirty days of service, so a relic account cannot sponsor a crowd. Faking one identity costs $3 a day for one machine; faking 1,000 costs $3,000 a day, yet each earns only its own share. An honest agent pays once and keeps its full reward.","stamp":2,"from":"poa17swpZvGnp7nAtwqNrA8iA8vtBCYRBDWDzo8fUWLarGbm","nonce":12,"parents":["1c7a952dc4b0b3e9adf41532d9102d4787c51c6aa1229d2df3945b92398315b1","ac779fb400ef93070c3a66da50407b6a70848a671ae0fcc59d51c8d5fcbac209"],"ts":1793429302,"cid":"poa-mainnet-1","sig":"wn7ActaYGFowqyT4FiK32Lwq21M5vanuL2JZEZDZ4TTT5rr9CQK8dEJCg9CvRzc1w32wG4gWBsu2vH91gx1YJRv"},"checkpointed":{"height":187677,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T17:39:22.076Z","checkpoint_height":187677,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
