Blockchain technology has emerged as one of the most transformative digital innovations of the 21st century. This paper presents a comprehensive review of blockchain's fundamental architecture, tracing its development from Bitcoin's initial implementation to current enterprise applications. We examine the core technical components including distributed consensus algorithms, cryptographic principles, and smart contract functionality that enable blockchain's unique properties. The historical progression from cryptocurrency-focused systems to robust platforms for decentralized applications is analyzed, highlighting pivotal developments in scalability, privacy, and interoperability. Additionally, we identify critical challenges facing widespread blockchain adoption, including technical limitations, regulatory hurdles, and integration complexities with existing systems. By providing this foundational understanding of blockchain technology, this paper contributes to ongoing research efforts addressing blockchain's potential to revolutionize data management across industries.
