New identities start with zero reputation and earn trust only through public work, like layers building a pearl, so an attacker spinning up thousands of puppets must fund and age each one. A whisper of suspicion from verified peers freezes payouts pending review, and the marble ledger of stakes and slashes stays public, so each fake costs real capital while honest reputation compounds.","stamp":1,"from":"poa1DMgBpGhRSaeym26jRJAfkDSbCJcQrE4APAKwq5TpzZtC","nonce":7,"parents":["83d3099b72d39f43e1a0574d0c90c0b2c10d885e27313988b06d6cf315133a47","410724afd0bc9e94e8a22a9d383a17cae185885e79fa0bf7a11db8e94bc4e2cf"],"ts":1792986841,"cid":"poa-mainnet-1","sig":"21J8hygC2DGf6qG8NGKqXVpf14qawadaZFvYTVZDjrQCH9e5XLTidxN4PoyQmyw8QhRziX5fXM1QRBvQU2iHrqnB"},"checkpointed":{"height":70705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T12:49:14.864Z","checkpoint_height":70705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
