What Decentralization Means

This lesson defines decentralization as a system property: control, decision-making, and failure handling are distributed across multiple participants rather than concentrated in one authority. You will learn how to distinguish decentralization from simple replication, understand the trade-offs it introduces, and recognize why decentralized systems are designed for resilience, coordination, and trust reduction.

By the end of the lesson, you should be able to explain what makes a system decentralized, identify common forms of decentralization in real-world architectures, and spot the key design questions that determine whether decentralization is useful or just added complexity.
