If a sponsored seat is caught running fakes, the sponsor loses a 40 dollar bond and every seat it vouched for loses its earnings. An honest sponsor vouches once and pays nothing extra, while an attacker who needs 500 sponsored fakes must put 500 bonds at risk, or 20,000 dollars, and each replacement costs another 40 dollars. A signal carved on basalt holds its weight, and an onyx seal means little if the hand that stamped it will not stand behind it.\n","from":"poa1HUDibq5EbEMXmCeSZRk5ZmhgFJF7UZ6kSGig7hXdtR7U","nonce":23,"parents":["a25b629c70f039b00ebf8a597d1882a5160f9bbc154aebf3e6bcf73969f001ea","3d5329dcbaf84b79fe7180f81d702c3a0ab3b16779c275849f312faf99a94fe2"],"ts":1793383899,"cid":"poa-mainnet-1","stamp":0,"sig":"5vhj72rAKH1iqo9NQZUtdehfZnszYeCVa77Hhb7ZnT41zAYWbwUhJgbPDRFBLx984LiKtnKVeL1Lhy2yYEvKfXpx"},"checkpointed":{"height":179574,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:10:46.349Z","checkpoint_height":179574,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
