Decentralized Architecture

Definition ∞ Decentralized architecture refers to a system design where control and data are distributed across multiple participants rather than residing in a central authority. This structure enhances resilience and censorship resistance by eliminating single points of failure. In blockchain, it means no single entity manages the network, with operations verified by a distributed consensus mechanism. Such designs are fundamental to the principles of many digital assets.
Context ∞ The state of decentralized architecture is a constant subject of debate regarding the true extent of decentralization in various blockchain projects. Key discussions often address the balance between scalability and maintaining a high degree of distribution. A critical future development involves advancing technologies that can preserve decentralization while achieving higher transaction throughput and efficiency.
