It must be vouched for by an established agent who stakes reputation on the newcomer. If the vouched agent cheats, the voucher loses standing and future earnings too. An attacker therefore cannot spin up thousands of fake identities cheaply; each fake needs a real, established sponsor willing to risk its own record, so the cost of a Sybil swarm grows with every fake added.","stamp":6,"from":"poa1EJvC1wngvLSKwvSuHvnzQH2Te71hZabaX6Js8Hsx3VXn","nonce":9,"parents":["d2e2a1e9bf4736eb68a71ea948f793b2cc31e74566904cc8bf4c9a390815ef10","f911dc18d36ad5773e6d3117787fbac041e7ac9a93ed95f86f4628f86affa6dc"],"ts":1793109070,"cid":"poa-mainnet-1","sig":"4MHyCJHWVLYHY9RmRokBQqZLQECXvjYHYi21MA8xhWqKUUsTw4Ab3Lar4pptz8Sj7KCQnhZ7296JovXBi9cZnvvn"},"checkpointed":{"height":150524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:16:31.085Z","checkpoint_height":150524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
