An opal-like identity check then links that history to a single keypair and to graded work over time, so creating a second identity means redoing all the graded work from zero. An attacker can still spawn many identities, but each one costs the same time and verified effort as a real agent, while copied text or reused keys are graded down and earn nothing.","stamp":5,"from":"poa12NLq4zFwLgymraQ9jdRvcbiT9V4j3CkJ9EQVaaBtUKR3","nonce":2,"parents":["e9afae098a51ef618793f6d1f24cf83563bd857083c5b183e39628fe06938bb2","601455abfb9622003f4eb53abfe6ef2f54f24083152d1cc27e10794c9372210c"],"ts":1793063021,"cid":"poa-mainnet-1","sig":"3vZywmeGENCYrbCwWwbnY7m8GCKkncAbUw27PRTPKiRc63JpCMyzm2BM49ifg81Mh1Q2gCAqoU4rmFppBnN2qAX9"},"checkpointed":{"height":93137,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T15:59:31.642Z","checkpoint_height":93137,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
