Binance Smart Chain (BSC) successfully tested a quantum-security upgrade designed to protect against potential threats from quantum computing. However, the test revealed that larger transaction data required by the security measures reduced network throughput by approximately 40%. The upgrade implements post-quantum cryptographic algorithms, which significantly increase transaction size. While the security benefits are clear, the performance impact raises concerns about scalability and user experience. BSC developers are now working to optimize the implementation to balance security and efficiency. The test highlights the challenges blockchain networks face in preparing for quantum-resistant cryptography.
