Is post-quantum crypto in Web3 real preparation or just long-term narrative building?
Summarize this article with:
The QAN XLINK desktop app release feels like another example of Web3 trying to position itself around post-quantum security before it’s actually needed. Most chains still rely on cryptography that could be vulnerable if large-scale quantum computing ever becomes practical, especially around wallet signatures and asset security. XLINK’s approach leans more toward compatibility than replacement, adding a quantum-safe layer on top of existing Ethereum tools like MetaMask instead of forcing users to migrate. I think that’s the only approach that could realistically work in crypto, because full migration rarely happens unless it’s absolutely unavoidable. That said, I’m not convinced yet whether this is meaningful early infrastructure or just narrative-building around a threat that may still be far off. Where do you fall on this, legit preparation or premature optimization? submitted by /u/Ge_Yo [link] [comments]
