Solana's Quantum-Resistant Signature Test Reveals Performance Challenges

Project Eleven, in collaboration with the Solana Foundation, conducted tests on quantum-resistant signatures within the Solana network. According to NS3.AI, the modified version of these signatures resulted in a performance slowdown of approximately 90%. Alex Pruden highlighted that the new signatures are significantly larger, about 20 to 40 times the size of current ones, which impacts the network's transaction processing capacity. Additionally, Pruden noted that Solana's direct exposure of public keys could render all wallets susceptible in the event of a quantum attack.
