PANews 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 showed that the new signatures are 20-40 times larger, causing transaction speeds to plummet by approximately 90%, severely damaging its high throughput advantage. More seriously, Solana's public key design is 100% exposed to quantum risks, a risk higher than that of Bitcoin and Ethereum.

Bitcoin and Ethereum are currently urgently developing quantum security solutions and preparing for "Q-Day." The CEO of Project Eleven warned that if they wait for the threat to materialize before taking action, it could take up to four years to fix it. This test exposed the security and performance dilemma of high-performance public blockchains and is also accelerating the implementation of quantum defenses in the industry.
