Interpreted Prediction
The novelty of postquantum signature schemes introduces risks, as the ecosystem is still understanding their failure modes, and past promising designs have been broken, highlighting the potential for disaster if a blockchain adopts an insecure choice.
AI Evaluation Notes
The prediction highlights the risks associated with adopting new post-quantum signature schemes due to their novelty and potential for failure. While it's difficult to definitively quantify the accuracy without a specific blockchain adopting a broken scheme and leading to a disaster, the general concern about vulnerabilities in post-quantum cryptography has been validated by ongoing research and discoveries of flaws in candidate schemes [cite: i].
