Gate News update: On April 4, Project Eleven partnered with the Solana Foundation to deploy post-quantum signatures on the test network, simulating how the network would operate after replacing the existing cryptographic algorithms. Initial results show that post-quantum signatures are roughly 20–40 times larger than current signatures, causing the network’s transaction processing speed to drop by about 90%, directly undermining Solana’s design advantages known for high throughput and low latency.
In addition, Solana’s public-key design exposes the entire network to quantum attack risk 100%. Attackers can choose any wallet and attempt to recover the private key, making the risk higher than for Bitcoin and Ethereum. Although Bitcoin developers are urgently looking for post-quantum solutions and Ethereum is preparing a “Q-Day” response plan, Solana is already ahead of the industry in post-quantum security experiments and currently has a post-quantum testnet that can actually run. Project Eleven CEO Alex Pruden said: “If the industry waits until quantum threats truly arrive to start fixing things, it may take four years.”
