ME News message, April 4 (UTC+8). As Bitcoin developers urgently search for quantum-safe solutions, Ethereum prepares for its “Q-Day,” and Solana is trying to address potential threats ahead of time. Project Eleven is collaborating with the Solana Foundation to deploy quantum-safe signatures (Post-Quantum Signatures) on the testnet, simulating 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 current signatures, causing the network to process transactions drop by roughly 90%, directly undermining Solana’s design advantage known for high throughput and low latency. In addition, Solana’s public key design exposes 100% of the network to quantum attack risk; hackers can choose any wallet to attempt to recover private keys. The risk is higher than what Bitcoin/ethereum face, with technical and community coordination challenges. Solana is leading the industry in quantum-safe experiments, and it has already secured a quantum-safe testnet that can be 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)
