user2080: From my understanding, today's cryptography will be vulnerable to attacks from quantum computers soon. Are there any plans that IOG or Charles has mentioned about how Cardano will deal with the rise of quantum computing in the next few years / decade? What measures will be taken to keep the network secure and business as usual?
Thanks,
Myles

user4302: While this may be a concern in the future, there is currently no quantum computing system powerful enough to pose a threat to modern cryptographic standards. That being said, there are quantum-resistant signature schemes that can be employed if needed, such as XMSS.
There are drawbacks however; the signatures for such schemes tend to be much larger than the elliptic curve schemes currently used, which would lead to faster chain growth. As such, quantum resistant schemes can and will be deployed as soon as quantum computers pose a significant risk. Until then, they are simply unnecessary.
