According to BlockBeats news on January 5, as reported by Cointelegraph, Solana developers have created a quantum-resistant Vault on the Solana blockchain to protect user funds from potential threats posed by quantum computers.
Solana's quantum-resistant feature is currently offered as an optional add-on rather than a full network security upgrade. This means that Solana users must choose to store their funds in the Winternitz Vault instead of the regular Solana wallet to ensure their assets are protected from potential quantum threats.
