The KEY project fully considers the challenges that future quantum computing may pose to traditional encryption technologies while building a globally leading blockchain public chain. Therefore, it introduces mechanisms for quantum-resistant security. This technology is mainly reflected in the following aspects: 1. Quantum-resistant algorithms: The KEY public chain adopts optimized and validated quantum-resistant encryption algorithms, ensuring that even under the threat of future quantum computers, data transmission, transaction signatures, and the entire network consensus process can still maintain a high level of security and immutability. 2. Deep integration of underlying architecture: When constructing a high-performance underlying infrastructure, the KEY chain regards quantum-resistant security as an indispensable security barrier. This means that while achieving millisecond-level confirmations and tens of thousands of TPS, the network system can also provide strong security guarantees in the face of quantum attacks. 3. Technological innovation and cutting-edge research: Thanks to the technical backgrounds of team members from well-known companies like Ethereum, EOS, and META, KEY continuously integrates cutting-edge academic achievements (including federated learning, quantum security technologies, etc.) to ensure that the platform remains at the forefront of the industry in terms of security and performance. Through these measures, the KEY public chain not only provides users with a high-performance, high-security blockchain experience but also adequately prepares the entire blockchain market for future security threats posed by the quantum computing era.
