Zano exploiter minted over a quadrillion fUSD, forcing blockchain rollback

The rollback is the real story: a privacy-focused chain chose state reversion over surgical remediation because the minted tokens were indistinguishable from legitimate supply, a trade-off that trades supply integrity for settlement finality. That choice affects anyone holding ZANO or building on it, since rollbacks set precedent for how future exploits are handled. Whether the network's credibility absorbs the hit, and whether the exploiter's method gets replicated elsewhere, are the open questions.
