Solana Is Now ‘Quantum Resistant’—What Does That Mean? – BitRss

Solana developers have created a quantum-resistant vault that uses a decades-old cryptographic technique to protect users’ funds from potential quantum computer attacks. The solution, called Solana Winternitz Vault, implements a hash-based signature system that generates new keys for each transaction.

The vault addresses a known vulnerability in blockchain technology: quantum computers could potentially crack the cryptographic algorithms that secure digital wallets. When users sign transactions, they expose their public keys, which theoretically could be used by sufficiently powerful quantum computers to derive their private keys through the Elliptic Curve Digital Signature Algorithm. (These stories might help you understand a bit more about that topic.)

The vault currently exists as an optional feature, not a network-wide security upgrade, so there is not really a f…
