Analysis: The Solana quantum threat experiment reveals the difficulty of balancing security and speed.

As Bitcoin developers urgently seek quantum security solutions and Ethereum prepares for "Q-Day," Solana is attempting to proactively address potential threats. Project Eleven, in collaboration with the Solana Foundation, has deployed post-quantum signatures on its test network to simulate network performance after replacing existing encryption algorithms. Preliminary results show that post-quantum signatures are approximately 20–40 times faster than current signatures, causing a roughly 90% decrease in transaction processing speed, directly impacting Solana's design advantages known for high throughput and low latency. Furthermore, Solana's public-key architecture exposes the entire network to 100% quantum attack risks; hackers could attempt to recover private keys from any wallet, posing a higher risk than Bitcoin or Ethereum. While facing technical and community coordination challenges, Solana is at the forefront of quantum security experimentation and already possesses a practically operational quantum security testnet. Project Eleven CEO Alex Pruden stated, "If the industry waits until the quantum threat actually arrives before starting to fix it, it could take four years." (CoinDesk)
