Analysis: Solana exposes the highest quantum risks, with an unsolvable dilemma between performance and safety.

CoinFeed reported on April 4th, citing Coindesk, that in response to the threat of quantum computing, Solana partnered with Project Eleven to deploy quantum-secure signatures on its testnet, achieving a working testnet. However, tests revealed that the new signatures are 20-40 times larger, causing transaction speeds to plummet by approximately 90%, severely impacting its high throughput advantage. More seriously, Solana's public key design is 100% exposed to quantum risks, a higher risk than Bitcoin and Ethereum. Currently, Bitcoin and Ethereum are urgently developing quantum-safe solutions and preparing for "Q-Day." Project Eleven's CEO warned that waiting for the threat to materialize before fixing it could take four years. This test exposes the security and performance dilemma of high-performance public blockchains and is also accelerating the implementation of quantum defenses in the industry.
