Blockchain Integration in Cloud Computing: Ensuring Transperancy & Security

Blockchain technology, with its myriad real-world applications such as faster cross-border payments, identity management, smart contracts, cryptocurrencies, and supply chain management, has solidified its place as the next innovation akin to the Internet.Despite previous attempts to develop digital currencies being thwarted by security1 and trust issues, blockchain stands out due to its decentralized nature, controlled by its users and resistant to alteration or forgery, fueling significant market hype and demand.Moving beyond its origins in cryptocurrency, blockchain has found utility in various sectors, paving the way for its simplification and wider adoption.Its key characteristics including decentralization, integrity, immutability, verification, fault tolerance, anonymity, audibility, and transparency are highly desirable.This paper provides an in-depth analysis of blockchain technology, examining its evolution, applications, benefits, cryptographic principles, challenges in distributed ledgers, and extensive usage in financial transactions.Through a detailed review, the critical challenges, and diverse applications of blockchain across different fields are discussed, particularly emphasizing its role in transaction systems, and summarizing various cryptocurrencies.Additionally, the paper offers suggested solutions to address the identified challenges, contributing to a comprehensive understanding of blockchain technology and its potential impact.
