Ok, this has been discussed before on this forum but only briefly, and not much since google’s Willow came out. Now, according to [this study](https://www.sciencedirect.com/science/article/pii/S2590005621000138#:~:text=However%20as%20with%20Monero%2C%20the,incentive%20for%20a%20quantum%20attacker.&text=ZCash%20is%20highly%20vulnerable%20to,algorithm%20and%20its%20signature%20scheme.), Zcash is much more susceptible to quantum computing than many other blockchains. However, Zcash likely has the ability to respond and reach consensus on a change to prevent this, if done early enough. For Bitcoin, it will difficult to implement change, and there is nothing they can do to stop Satoshi’s wallet from being hacked, even if they make the network more quantum proof. Are there any current ongoing plans to get ahead of this issue? ---

On the contrary, only Zcash is the least vulnerable to quantum attacks. The most ridiculous is the following paragraph: ZCash is highly vulnerable to quantum attack against both its consensus algorithm and its signature scheme. However, the most damaging attack found against ZCash is vulnerability of its zero-knowledge proof protocol ZK-SNARKS, as this obfuscation method requires a trusted set up and therefore the production of a public parameter, which is a public key. If a quantum attacker gains the private key to this public parameter, they will be able to generate tokens at will. Zcash does not have a trusted setup in Halo 2, this is already an extremely backward and outdated article. ---

Yes, that is the exact paragraph that stood out to me, and it definitely didn’t make sense on its face. My first thought was that it would be less vulnerable, especially if using your shielded address. That’s for clarifying that! ---

Good recent thread from Zooko: > Also, previously discussed in-depth: > [@Is Zcash actually quantum private?](https://forum.zcashcommunity.com/t/is-zcash-actually-quantum-private/40706): > > Hi, First I want to express my admiration for the Zcash team (big fan of @daira especially!). I’ve been studying the anonymity and privacy aspects of Zcash in detail. I apologise as I’m not a cryptography pro, I’m just a really serious user trying to understand it as well as I can. My goal is to be post-quantum private, i.e. not have my transactions publicly traceable or linkable by a quantum computer, based on what we know so far about QC. If you do it right, Zcash appears to be by far the m… ---

Nice! Thanks for sharing this Shawn. ---

Quantum computing is like the long awaited return of astronauts on the moon, it’s perpetually only 2 years away 😂 ---

To be fair, the old pools can still be a vulnerability until they are deprecated.
