Briefing

Blockchain systems face escalating security threats from complex applications and advanced attack techniques, jeopardizing their development and adoption. This paper offers a comprehensive cryptographic review, dissecting attacks across the blockchain’s six architectural layers ∞ data, network, consensus, contract, incentive, and application ∞ and detailing specific mitigation strategies for prevalent threats like 51% attacks, double-spending, and reentrancy. This rigorous cryptographic perspective is crucial for designing resilient blockchain architectures capable of withstanding future adversarial advancements, ensuring long-term system integrity.

Context

Before this research, the prevailing understanding of blockchain security often overemphasized its inherent “trustless” nature, overlooking the dynamic evolution of attack methodologies. While foundational cryptography provided initial safeguards, a systematic, multi-layered analysis of how these cryptographic primitives interact with evolving attack vectors across the entire blockchain architecture remained a critical unsolved problem, leading to persistent vulnerabilities in deployed systems.

Analysis

This paper’s core mechanism is a systematic, cryptographic-centric framework for analyzing and mitigating blockchain vulnerabilities. It does not introduce a new primitive but rather provides a structured lens through which to view existing cryptographic elements ∞ like hash functions and digital signatures ∞ as both foundational security enforcers and potential points of failure when confronted with sophisticated attacks. It fundamentally differs from prior, more generalized security assessments by offering a granular, layer-by-layer breakdown of cryptographic attack surfaces and corresponding defense solutions, moving beyond abstract principles to concrete, actionable insights for system hardening.
