Post Quantum signatures exist (dilithium, falcon, etc). One major/commonly cited reason I've observed for why we haven't integrated these sigs is due to key size (~20x key size of ECC).

However, why not just use a P2PQPKH (Pay to Post Quantum Pub Key Hash) type op code to facilitate this?
-Hashing results in a fixed size output (same as existing P2PKH stored on chain),
-PQ sig schemes resolve unresolved issues in BIP360 "short exposure attacks"

I understand there's still the unresolved issue of signing and key storage on existing cold storage hardware, but that seems like small potatoes in comparison to resolving the above larger issues.

Will this thread be considered plagiarism or is it because the same thread has been opened twice for some other reason? I am actually very inexperienced with the (Development & Technical Discussion) board. I am just trying to raise the issue, you decide.https://bitcointalk.org/index.php?topic=5581303.0
