Zcash Developer Zakura Proposes Fix to Stop Quantum Computers Linking Shielded Swaps

A Zcash developer has put forward a fix for a quantum-computing privacy risk

A Zcash developer known as Zakura has proposed a fix meant to stop quantum computers from linking shielded swaps, according to a report from Decrypt published on October 19, 2026.

The proposal deals with a privacy risk for shielded swaps, which are trades made on Zcash using its private transaction features. The concern described in the report is that future quantum computers could connect, or link, these private swaps to each other.

Key points from the report

• The proposal comes from a Zcash developer named Zakura.
• Its stated goal is to prevent quantum computers from linking shielded swaps.
• Shielded swaps are trades that use Zcash's privacy features.
• The report was published by Decrypt on October 19, 2026.

What is confirmed

The supplied material confirms that a Zcash developer named Zakura has proposed a fix aimed at stopping quantum computers from linking shielded swaps. It also confirms the report was published by Decrypt on October 19, 2026.

Why this matters for Zcash users

Shielded swaps rely on privacy features, so a method that links them could reduce that privacy. The proposal is a response to a possible future risk tied to quantum computers, which are a different kind of computer than those used today.

What is still unclear

The supplied material does not describe how the proposed fix works, whether it has been reviewed or accepted, or when it might be used. It also does not say whether the linking risk is possible today.
