Briefing

The financial sector faces an impending cybersecurity crisis as quantum computing advances threaten the foundational cryptographic protocols underpinning blockchain and digital finance. This paper introduces a structured four-step framework to systematically assess the feasibility and benefits of integrating quantum solutions, encompassing classical quantum applications, blockchain technologies, and post-quantum cryptography. This framework provides essential guidance for developing secure, quantum-resilient financial operations and blockchain architectures, ensuring long-term stability in the quantum era.

Context

Prior to this research, the financial industry largely grappled with an unstructured approach to evaluating the dual impact of quantum computing ∞ its potential for computational advantage and its profound cybersecurity risks to existing cryptographic infrastructures like those in blockchain. A comprehensive, integrated methodology for assessing quantum readiness and mitigating emerging threats was notably absent.

A sophisticated cryptographic chip is prominently featured, partially encased in a block of translucent blue ice, set against a dark, blurred background of abstract, organic shapes. The chip's metallic components and numerous pins are clearly visible, signifying advanced hardware

Analysis

The paper’s core mechanism is a structured four-step framework designed to systematically evaluate quantum solutions within finance. This framework integrates classical quantum applications, such as portfolio optimization and risk analysis, with an examination of blockchain and post-quantum cryptography. It fundamentally differs from previous approaches by offering a holistic perspective, guiding stakeholders through computational scalability, error tolerance, data complexity, and practical implementability to identify where quantum approaches can surpass classical techniques and how to build quantum-resilient systems.
