Solana testnet deploys quantum-safe signatures, with transaction speeds decreasing by approximately 90%

According to Coindesk, Solana partnered with Project Eleven to deploy quantum-safe signatures on the testnet, enabling a functional testnet. The tests showed that the new signatures increased in size by 20-40 times, resulting in about a 90% reduction in transaction speed. Solana's public key design is fully exposed to quantum risks, posing a higher threat than Bitcoin and Ethereum. Bitcoin and Ethereum are currently developing quantum-safe solutions. Project Eleven's CEO warned that fixing the vulnerabilities after a threat emerges could take up to four years. This test highlights the security and performance challenges faced by high-performance public blockchains and accelerates industry efforts to enhance quantum defenses.
