Decentralized distributed systems have become pivotal in modern digital ecosystems, offering robustness, scalability, and autonomy. However, conventional access control mechanisms fall short in ensuring secure, transparent, and tamper-evident data operations within these systems. This paper explores how blockchain technology can be employed to enforce access control policies and enable auditability in decentralized infrastructures. We investigate prior implementations, analyze architectural models, and identify research gaps. The findings support blockchain's potential in decentralizing trust and improving compliance through immutable logs and smart contract-based enforcement mechanisms.
