Bitcoin and Ethereum Aren’t Ready For Quantum Computers, Researcher Says
In brief Quantum computers threaten blockchain security by cracking private keys with Shor’s algorithm. Chains using EdDSA, like Solana and Sui, are easier to upgrade for quantum resistance. Older chains like Bitcoin face steep risks and costly upgrades, or risk leaving assets exposed. Quantum computing could one day break the cryptographic foundations that secure trillions…
