Discussion Post on PQC - Quantum Vulnerabilities of Blockchains

Very interesting topic @Harvesto … from what I have read about this topic QC mostly poses a threat to discrete log or integer factorization-based public key signature techniques. Currently, the discrete log issue in an elliptic curve group is what makes bitcoin work. The ECDSA signature algorithm includes this. If quantum computing becomes a reality, it would be foolish to keep this module in place. To be more realistic, this should be amended in a few years with a soft fork, which is likely t…

I’m nominating this response by @Gift82822546. It’s a great response to a question, provides additional resources to back up the reasoning being applied, and does a great job of confronting overly simplified implications of QC. Plus, it was easy to follow the reasoning.
