Cryptocurrencies may face one of their biggest challenges once quantum computers become powerful enough to break today’s encryption standards.
If quantum systems can efficiently break algorithms like RSA or ECC, they can theoretically derive private keys from public ones, exposing wallets and transactions.
What will change:
- Wallets must adopt quantum-resistant cryptographic methods
- Future blockchains need quantum-secure algorithms
- Users and developers must upgrade their security models
While the threat is not immediate, preparing now ensures that digital finance remains secure in a quantum-powered future.
