Fog computing refers to a decentralized computing structure that extends cloud computing capabilities closer to the data source. In cryptocurrency, this approach enhances transaction processing and data management by distributing computing resources across various nodes.By reducing the distance data must travel, fog computing minimizes latency, which is crucial for real-time applications such as trading and peer-to-peer transactions. This ensures faster confirmations and improved user experiences.Moreover, fog computing increases security by decentralizing data storage. Since sensitive information is not stored in a single location, the risk of significant breaches is diminished. Each node can also process transactions independently, mitigating the impact of network congestion.The combination of lower latency and enhanced security makes fog computing a valuable asset for applications in cryptocurrency, supporting innovation and efficiency for users and developers alike.
