<p>On April 16th 2025, Solana quietly patched a zero-day vulnerability in its Confidential Transfers feature — powered by zero-knowledge proofs (ZKPs). The bug could’ve let attackers mint unlimited tokens. And here’s the real problem: no one really knows if bugs like this in ZKP systems have actually been exploited. There’s no audit trail. No accountability. Not for the issuer. Not for regulators. Not for users. Just a silent, irreversible break in the integrity of the ledger.</p> <img src="https://track.hubspot.com/__ptq.gif?a=2704830&amp;k=14&amp;r=https%3A%2F%2Fblog.digitalasset.com%2Fblog%2Fzero-knowledge-proofs-whe-privacy-needs-more&amp;bu=https%253A%252F%252Fblog.digitalasset.com%252Fblog&amp;bvt=rss" alt="" width="1" height="1" style="min-height:1px!important;width:1px!important;border-width:0!important;margin-top:0!important;margin-bottom:0!important;margin-right:0!important;margin-left:0!important;padding-top:0!important;padding-bottom:0!important;padding-right:0!important;padding-left:0!important; ">
