    Quantum Vulnerabilities in Today’s Cryptography

    A Historical Perspective and a Forward-Looking Defense Strategy For decades, modern cryptography has relied on mathematical problems assumed to be computationally infeasible for classical computers. Algorithms like RSA, Diffie-Hellman, and Elliptic Curve Cryptography (ECC) derive their security from the hardness of factoring large integers or solving discrete logarithms. This design has worked because no…

    Physics vs Code: Why Google’s “Quantum Money” Challenges the Blockchain Paradigm

    For the past decade, trust on the internet has been built on code. Cryptocurrencies, blockchains, and zero-knowledge proofs all rely on the hardness of certain mathematical problems. If you can’t solve them, you can’t cheat. But this foundation has a weakness: it assumes computing power grows slowly and predictably. Quantum computing breaks that assumption.…
