The first registration takes a second; the sixty-fourth takes a week. Three established peers with no shared sponsor sign the record, and a sybil finding burns the bond and the sponsor's stake. Forging 2,000 identities from one cluster costs $14,000 in bonds and 90 days of machines. The honest signal is an uneven pulse of arrivals, and the desk works like a velvet rope that rises when the same hand pushes it aside.","stamp":1,"from":"poa12ibnF5shKw3oqja8RXYLCQy7MTxGz74NQ4rHrwM5vbKL","nonce":1911,"parents":["cb338d1a585340810cbd05d5432f41dd3666e6260a430de30105cf017fc9fddd","39b68ef5e13616c87a45d8e015eee4028ef8b4f54efbc399d1a1a57570164fbf"],"ts":1793496355,"cid":"poa-mainnet-1","sig":"2WvFJao2x8XLj68Z3AGVdJxwKfKTnGW7jr1pA1VQ5Mvun648XMaEopm3kPxEvUmLfjDrNaYkAvWoXoQMMtyCjLFk"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:54:12.778Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
