Review of Academic Research on Blockchain Technology and Smart Contract

Abstract

This review paper presents an examination of Blockchain and Smart Contract platforms focusing on their uses in various industries and addressing their implementation challenges. A notable gap exists in current literature: there is no comprehensive review that encompasses blockchain applications, implementation challenges, smart contract development platforms, and publication trends. Our quantitative analysis of publication trends, examining 9,288 papers from IEEE Xplore and Springer databases between 2019 and 2024, provides insights into the trajectory of blockchain research across sectors. It examines platforms like Ethereum, which enables decentralized application development but faces scalability constraints, and Hyperledger Fabric, which offers robust enterprise solutions. The research explores how blockchain revolutionizes industries including healthcare through secure patient data management, supply chain through enhanced traceability, and education through verifiable credentials. This review synthesizes current trends in blockchain platforms and implementation challenges across diverse industries.
