Distributed Systems

Definition ∞ Distributed Systems are collections of independent computers that appear to their users as a single coherent system. These systems achieve fault tolerance and scalability by replicating data and computation across multiple nodes. Blockchains are a prominent example of distributed systems, characterized by their decentralized and immutable ledger.
Context ∞ The ongoing development and adoption of distributed systems, particularly in the realm of blockchain technology, are subjects of considerable attention. Discussions often involve the challenges of achieving consensus, ensuring data consistency across disparate nodes, and managing network latency. Future advancements are expected to further enhance the robustness and performance of these complex computational architectures.
