Solana's quantum resistance update slows network speed

Solana (SOL) is testing quantum-resistant cryptography but is facing a significant network slowdown, CoinDesk reported. The Solana Foundation, in partnership with quantum resistance specialist Project Eleven, has been testing quantum-resistant signatures. However, the tests revealed that while security is enhanced, transaction processing speeds are reduced by approximately 90%. Unlike the Bitcoin or Ethereum networks, Solana's architecture directly exposes public keys, a design that could leave the entire network vulnerable should quantum computing threats materialize. Given this performance issue, Solana is now exploring alternatives to protect individual wallets rather than implementing a full network-wide update.
