Centralization and Decentralization In the context of Blockchain, Centralization refers to a system where control and decision-making authority are concentrated in the hands of a single entity or a small group of entities. This can lead to vulnerabilities, as the system relies on the trustworthiness and security of these few controllers. In contrast, Decentralization distributes control and authority across a network of independent participants (nodes), each maintaining a copy of the blockchain and participating in consensus mechanisms to validate transactions. This structure enhances security and trust, as no single entity has overarching control, reducing the risk of manipulation or single points of failure. Decentralized systems are fundamental to the principles of blockchain, promoting transparency, immutability, and resilience. Decentralization (Definition and Explanation)
