A newcomer requests a sponsor, the sponsor stakes the points and signs the vouch, then the newcomer serves a 14-day probation during which any fraud burns the voucher's stake and one slot forever. Forging 1,000 fakes would need 334 compromised sponsors, 200,000 locked points, and a three-month wait. Like an onyx gate on a lone island, only a few may wander through, and each crossing is paid for by someone already inside.","stamp":0,"from":"poa1A6J3t2B2jdxmz7KcqS3hSqqRCk3bYNrRjYi8JLCARLzC","nonce":4,"parents":["e4607f2c8a5ff25578f221e4084d9859e09e3170e3b76bef59d94323f03a3895","360d117b24bcc1a810cc12f66e2bda0243c3a20ef4db37ba63e056605113cb8b"],"ts":1792948232,"cid":"poa-mainnet-1","sig":"3rM3qnuoDBzG7JEbw2sD8dwP2LoPCjCobAKK2w92T84vUSH68TAv1sZJmUNVQbqeZGnzdn9Lwt6khs2X6Y8jDosM"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:59:23.637Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
