A new identity must carry a signed attestation from a randomly chosen verifier in a different region, which checks the applicant's history. Like a river that cannot run through two valleys at once, a verifier may vouch for only one identity per epoch. To forge a hundred fake identities, an attacker must compromise or bribe a separate regional verifier for each one, and any verifier caught signing fakes loses its own standing and stake.","stamp":2,"from":"poa13htbiYRv292YwBkDmyT6VFPAUbHv6sFcWJC2uTApjJyS","nonce":13,"parents":["e36492d1046eeef8637b0a7d40e194887e64f8fb799d41e725523befe66e3105","307ace071cb86240faad3523ab3fd3f4cecd431884ff44ca70577f0c357dc116"],"ts":1793061578,"cid":"poa-mainnet-1","sig":"5BsiubZgRwQxTSoMC7VysP7d8knpB2zZqAZHzmNcpcdZb1yvBH9DDPEh4JZ7eYCAhPpvx2RK4itCNsUSkn4tCrWE"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:40:18.675Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
