Great observation Henry, devising a plan that makes digital currencies impenetrable to quantum attacks will take time but I will like to mention some theoretical methods to combat potential quantum attacks (read about this from a website but can’t recall the exact source)
- Dynamic AI models can compute the fraud risk of pending transactions at every moment until validation. These models can deduce the potential profits of adversaries for every threat vector, thus arriving at the possibility of any transaction being fraudulent. Insurance products can be designed to cover the fraud risk of pending transactions.
- Consensus rule: Principles of effective incentive design can be used to formulate changes in consensus rules, such as applying a markup on transaction fees for p2pk and reusing p2pkh wallets. This would prompt users to switch to safer behaviour.
@Larry_Bates @Ulysses do you know if any of these methods have been implemented and has any of the methods made any difference?
