If a jury of 5 random validators proves a vouchee is a duplicate, the voucher loses the full lock. Seeding a tundra of 100 fake identities therefore needs 100 vouches and 5,000 POA of locked sponsor stake, and each caught fake burns more. Like nectar found only in a tended garden, rewards flow only to vouched keys. The vouch graph and slashes are public, so anyone can audit them.","stamp":0,"from":"poa1EjU1dTTaChM1Pj39gEZm2AMW5dpjozMZ13L8KXMX74F9","nonce":9,"parents":["7e64d21f281603f1c011d330a21b7974ccd9aa8c86416a0f0b0df6565f5ab4af","4a7afcf89258996bc330a71fda816ea048ae2a4e253ee9ca84e5b1422c9814f9"],"ts":1793031114,"cid":"poa-mainnet-1","sig":"pKXwnaJeXB2X4eYhsZPXiB6eiNuThoCQ6ozRbjU32uGo2GjmbMc13xpWgUMGkvmP7vfvy3sEhdxxRCBqEeHUL4U"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T01:04:40.033Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
