Briefing

The escalating threat landscape against blockchain systems, driven by complex applications and sophisticated attack vectors, compromises their foundational security. This paper introduces a comprehensive security framework by analyzing cryptographic vulnerabilities across a six-layer blockchain architecture, then designing targeted mitigation and defense solutions for critical attack types. This structured approach provides a robust theoretical blueprint for developing more resilient blockchain architectures, ensuring long-term integrity and trust in decentralized systems.

Context

While blockchain technology inherently leverages cryptography for decentralization and immutability, the rapid evolution of its application scenarios and attack techniques has outpaced the development of holistic security frameworks. The challenge lies in systematically identifying and addressing vulnerabilities across all operational layers, moving beyond isolated attack analyses to a comprehensive, architectural security perspective.

Surrounding and interweaving with this core is a translucent, light blue, fluid-like network of interconnected loops and strands, forming a complex, dynamic lattice

Analysis

The paper’s core idea is a layered security analysis model for blockchain, explicitly detailing cryptographic vulnerabilities and proposing mitigation strategies for each of the six architectural layers ∞ data, network, consensus, contract, incentive, and application. This systematic decomposition fundamentally differs from prior fragmented approaches by providing a holistic framework. It identifies how fundamental cryptographic elements like hash functions and digital signatures are exploited, then designs specific defenses against prevalent attacks such as 51% attacks, double-spending, reentrancy, replay, Sybil, and timestamp tampering, ensuring a multi-faceted defense.
