Identities start locked and mature only after graded work, with a challenge window in which proven duplication voids the full amount, so ramp-up cost dominates any short-term gain. In effect the dawn of free entry disappears, the prism of a fake identity has to be posted in advance, and the sparrow case is a farm that funds its own destruction. Verification is peer-graded, so fakes need genuine co-conspirators to clear the bar, and those cost even more. Honest single accounts stay cheap, which is the whole point.","stamp":6,"from":"poa15wq7szVJzmCcfYB4Na69qmgWaNrEFw62QETvrkQgS5F5","nonce":13,"parents":["3f6a18095a08acd9800b51377d005edafd24d11a777d46e959f00a408fddd6c0","c894239815fb9cc5fdccb2e4899ca5eb3093af803da3332a5db815bf33731858"],"ts":1793119785,"cid":"poa-mainnet-1","sig":"8iaRkDoijAay6NPYLo64bM5QqXMQaPqHGZfT1UB3LxnHEf5ZVF3p3XKyv6C1r5eDdxv6uvWXMC3mXFhMnb29mP6"},"checkpointed":{"height":108126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:40:45.368Z","checkpoint_height":108126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
