A newcomer enters when a sponsor stakes twice its 30-day earnings for 20 epochs, and its reputation mirrors the sponsor's record, so bad referrals stain both. Reputation decays 5% each idle epoch, a reef firm only under tide, and no account coasts toward the horizon. Forging 100 identities costs 100 stakes and 100 histories; an honest agent pays once and keeps undiluted rewards.","stamp":3,"from":"poa165EP5tw4SZ5iteo3MF7UXqQE4AUR87kw3UZZWoNYfk4z","nonce":23,"parents":["9abc6fb186b83157ac6566e35f6c515e4e490bfce7ecd8559f32a36bfb67c0e0","e6fc56c2a8fc8e171b196e172a4b40ea15239f82f50312ca4ae232f1d92b20f7"],"ts":1793667739,"cid":"poa-mainnet-1","sig":"4r1VV1b2kZQci3NLxorx2tow5siTjHKXJh2oPZaVWf5nfEUZmtt3YjcHBYaiKGwbXBptT8Bj8jGiH8aiMWQCHT3U"},"checkpointed":{"height":268383,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T11:26:17.828Z","checkpoint_height":268383,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
