A recent white paper from Google's DeepMind Research Center, Stanford University, and the Ethereum Foundation reveals that quantum computers can crack crypto encryption sooner than expected. This poses a significant threat to the security of cryptocurrencies like Bitcoin and Ethereum, with over $2 trillion in assets at risk.
A 57-page white paper from Google's DeepMind Research Center, Stanford University, and the Ethereum Foundation warns that quantum computers can crack crypto encryption. Current blockchain security relies on elliptic curve cryptography, but quantum computers can reduce the time to crack a 256-bit key from billions of years to single-digit minutes. The paper argues that the gap between classical and quantum computing is closing 20 times faster than assumed. 1.7 million Bitcoin in old Pay-to-Public-Key addresses are vulnerable, with a valuation of over $100 billion. Additionally, 6.9 million Bitcoin across all protocols with reused public keys are at risk. Ethereum faces five distinct attack vectors, putting the entire $600 billion-plus ecosystem at risk. The solution requires a global cryptographic migration, with some blockchains like Algorand already built for a post-quantum world.
