Digital forensics plays an important role in investigating cybercrimes, data breaches, and other digital misdeeds in an increasingly connected world. With the proliferation of blockchain technology, a new dimension has emerged in the world of digital forensics. This work presents a comprehensive review of the intersection between blockchain and digital forensics, exploring the various ways blockchain technology influences and challenges the traditional practices of digital forensic investigations. This work begins by elucidating the fundamental concepts of blockchain technology, emphasizing its decentralized and immutable nature, cryptographic underpinnings, and its uses in cryptocurrency transactions. Subsequently, it delves into the potential benefits of blockchain for digital forensics, such as providing transparent and tamper-proof logs of digital activities and transactions. However, this chapter also discusses the unique challenges posed by blockchain in digital forensic investigations.
