Abstract: Blockchain technology has evolved to solve the complexity and privacy issues associated with online digital content distribution in the last decade. Several studies have centred on different implementations of blockchain technology, and there is no comprehensive survey of the technology from both a technical and an application viewpoint. To close this gap, we conducted a detailed blockchain technology survey. This paper gives an in-depth look at blockchain technology. It discusses the blockchain fundamentals, taxonomy, characteristics, architecture of blockchain, and accessible consensus mechanisms used in the various blockchain systems. This paper also gives blockchain applications in multiple domains, including finance, medical, banking, etc. In addition, this paper presents an overview of the various problems that currently exist in blockchain technology and future research directions.

Keywords: Bitcoin; consensus algorithms; smart contract; blockchain architecture; blockchain applications; blockchain challenges.
