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.
