What makes a system distributed? Why are they important, and how do they relate to emerging technologies like blockchain?
In a world increasingly dependent on digital infrastructure, “distributed systems” have become a foundational concept shaping how we interact with technology. Distributed systems are at the core of modern applications, from cloud computing to online banking, from video conferencing tools to cryptocurrency networks. These systems allow data, computation, and control to be shared across multiple locations. It provides resilience, scalability, and performance that centralized systems often struggle to match.
A distributed system is a network of independent computers that appears to users as a cohesive system. Each node (or computer) in the system communicates and coordinates with others to achieve common goals. Unlike centralized systems, where one machine or server handles all the computation and storage, these systems share the workload. This enables high availability and fault tolerance. If one node fails, the system continues its operation.
Some familiar examples of distributed systems include cloud storage services like Google Drive, content delivery networks (CDNs) such as Netflix’s video streaming platform, and global messaging services like WhatsApp.
One of the most compelling uses of distributed systems today is blockchain. Blockchain is a specific type of distributed ledger system. Rather than relying on a central authority to record and validate transactions, it allows participants in a network to reach consensus through decentralized computation. This structure enhances security and transparency, making it ideal for financial systems, supply chain tracking, and digital identity management.
In Chains That Bind Us, author Phillip G. Bradford clarifies this relationship. This book explains the concepts by showing how distributed systems are the backbone of blockchain technology. It discusses the practical exercises that walk readers through how distributed systems function in real blockchain implementations. Whether it’s by using physical Raspberry Pis or their virtual counterparts, Bradford provides a hands-on learning experience that reinforces the foundational ideas behind decentralized consensus and system synchronization.
What makes Chains That Bind Us especially valuable is that it contextualizes blockchains within the broader field of computing. Readers gain insight into why distributed systems matter and how understanding them unlocks the potential of technologies like proof-of-work blockchains, clockchains, and public ledgers.
Distributed systems will only grow in relevance as we look to a future filled with AI, smart cities, autonomous vehicles, and decentralized finance. Mastering the fundamentals today prepares us to understand and shape the innovations of tomorrow. And in this context, Chains That Bind Us serves as a crucial bridge between theory and practice. It empowers both students and professionals to build, test, and explore the future of computing.
