ME News message: On April 4 (UTC+8), as Bitcoin developers urgently search for quantum-safe solutions, Ethereum is preparing for “Q-Day,” and Solana is trying to respond to potential threats in advance. Project Eleven is currently partnering with the Solana Foundation and, on the test network, has deployed quantum-safe signatures (Post-Quantum Signatures) to simulate how the network would perform after replacing the existing cryptographic algorithms. Preliminary results show that quantum-safe signatures are about 20–40 times larger than the current signatures, leading to a drop of about 90% in the network’s transaction processing speed, directly impacting Solana’s design advantage, which is known for high throughput and low latency.

In addition, Solana’s public-key design leaves the entire network 100% exposed to quantum-attack risk. Hackers can choose any wallet and attempt to recover the private key. The risk is higher than the technical and community-coordination challenges faced by Bitcoin and Ethereum. In quantum-safe experiments, Solana is leading the industry and already has a quantum-safe testnet that can run in practice.

Project Eleven CEO Alex Pruden said, “If the industry waits until quantum threats truly arrive before starting to fix things, it may take four years.” (Source: ODAILY)
