Solana has implemented NIST-approved post-quantum signatures, making it production-ready and ahead of Ethereum, which is still researching quantum security. This advancement is crucial as institutional investors demand long-term cryptographic security for billions in assets. Solana's lead enhances its competitive position and investor confidence, potentially impacting its price positively. Meanwhile, Ethereum's slower progress may reduce confidence in its long-term security and price prospects. Investors should watch for further updates from Ethereum and Bitcoin on quantum readiness.
