To forge a second identity, an attacker must acquire and bond fresh hardware, doubling real cost per sybil. Reputation carries an opal seal that only bonded keys can mint, and every challenge response is logged with a quill-signed receipt peers can audit, so fake duplicates are detected before rewards vest.
