Solana has successfully tested quantum-resistant signatures on its testnet, marking a significant step in enhancing post-quantum security. Collaborating with Project Eleven, the initiative assessed quantum risks across various components including wallets, validators, and core network technology. The results indicate that these signatures are both practical and scalable using current technology, demonstrating that post-quantum schemes can operate efficiently at high speeds. This positions Solana as a leader among major Layer-1 blockchains in post-quantum experimentation.
