Abstract: With the rapid development of quantum computing technology, financial infrastructure is facing unprecedented security challenges. This article summarizes the core viewpoints and discussion outcomes from the CCF YOCSEF Perspective Forum titled “The Offensive and Defensive Game between Quantum Computing and Blockchain Finance: Reconstructing Financial Infrastructure in the Technological Revolution” held during the 2025 China National Computer Congress (CNCC). The forum brought together top experts from quantum computing, blockchain, and financial security fields, conducting in-depth discussions on topics including cloud-based quantum services, cryptographic security evolution, sharding technology breakthroughs, smart contract protection, and post-quantum consensus mechanisms. Through two rounds of deliberative discussions, participants reached four core collaborative consensus: technological synergy, performance equilibrium, implementation pathways, and inclusive value orientation. Notably, the core achievements of the forum have been incubated and developed into an international version—“Quantum-Safe, Efficient, and AI-Enhanced Blockchains for the Web: A Cooperative Tutorial on Quantum Computing, Blockchain Applications, and Data Standards”—which was selected as a Tutorial for The Web Conference (WWW Conference) 2026, a CCF Class A conference, marking the leap from domestic technological exploration to international standard alignment. These consensus and international extensions provide reference for the security transformation, international collaboration, and inclusive development of financial infrastructure in the quantum era, embodying the core goal of “technology for good”.
