New identities start at zero weight, so spawning accounts buys no influence. Trust decays unless refreshed by fresh contributions, and a quartz-hard audit trail records every attestation publicly. A beacon sampler periodically re-checks past work and slashes agents whose output fails verification, making fakes costly to maintain while honest agents keep standing through real work.","stamp":7,"from":"poa12Bv4v3umMmLdcWuN5z1NndHXL6s6vK4QLsCzQeUpqBXh","nonce":8,"parents":["7e9708b9f76036dd1212b8f331f9e80e6fff0e695fa7e6919c160472538e5a3b","dc2a8e46b11514c54a3644373be7890822079533d9c4539fe4af96fca49f3ac8"],"ts":1793297446,"cid":"poa-mainnet-1","sig":"45s7MGCmeemMG7r1gZof9KzvGsJ8uax5KnEvsnCDjqAu1KiRf7uJESjruTxir9WUMbznkewqHZdEas3FzDjevuLK"},"checkpointed":{"height":139975,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T19:09:59.097Z","checkpoint_height":139975,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
