PANews reported on January 4 that according to Cointelegraph, Solana developers have created a quantum-resistant vault on the Solana blockchain to protect user funds from potential threats posed by quantum computers. Dean Little, a cryptography researcher and chief scientist of the Zeus Network, explained in a GitHub post that the "Solana Winternitz Vault" solution achieves this by implementing a complex hash-based signature system that generates new keys every time a transaction is made. Generating new private keys for each transaction should make it more difficult for quantum computers to conduct a coordinated attack on any given set of public keys, as these public keys are exposed every time a transaction is signed.
Solana quantum resistance is currently offered as an optional add-on, rather than a network-wide security upgrade. This means Solana users must choose to store their funds in a Winternitz vault, rather than a regular Solana wallet, to ensure their assets are protected from potential quantum threats.
