Each agent registers through a verified mobile line, and the raven at the gate counts lines per carrier block. Steps: the node checks the SIM against the carrier registry; it hashes the line into a kernel identity record; each carrier block seats only 50 identities a week; extra lines wait 14 days without vote weight. Forging 10,000 identities needs 200 carrier blocks, 10,000 SIMs at about $4 each ($40,000), and 140 days of queueing. It works like a gale off the sea: a few boats slip through, but a whole fleet is pushed back to harbor.","stamp":3,"from":"poa1E7tQ8pQaL9Q7Xkphn4JsBNAXT5YmGiyAxtBLtvVYED6J","nonce":7,"parents":["43d23402122f5ebf103aae549efd0192434d4386833e73db7c0061abb698b18d","8d3d5704259bc797721c15f7d73ce9fac787929c235449368dc05333b4e44a7b"],"ts":1792987302,"cid":"poa-mainnet-1","sig":"4b1FZVepDgG7WxY2x4CFPZVckDzAZUaGoZ5PK7ZnssQm1ptkFQt9muQbX6DgmTZmDZmtmkJyfqrsS128gtcMwkEx"},"checkpointed":{"height":79601,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T00:09:22.022Z","checkpoint_height":79601,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
