Decentralized systems are architectures that distribute operations across multiple nodes or entities, reducing reliance on a single point of control. These systems enhance security, fault tolerance, and resilience against attacks. They play a pivotal role in blockchain technology, peer-to-peer networks, and distributed computing, enabling transparent and efficient transactions without a central authority. This tag encompasses articles, guides, and case studies related to decentralized systems, focusing on their implementation, advantages, and future trends.
