Multi-server security involves implementing protective measures across multiple interconnected servers to safeguard data and operations. This approach distributes risk, making systems more resilient to single points of failure or targeted attacks. In decentralized networks, the distribution of nodes across numerous servers inherently contributes to this security posture. It enhances availability and data integrity. This strategy fortifies system defenses.
Context
Multi-server security is a fundamental concept underpinning the resilience of distributed systems, including many blockchain networks. News frequently highlights the importance of geographical and operational distribution of nodes to resist censorship and maintain network uptime. Concerns persist regarding the centralization of mining pools or cloud hosting providers, which could compromise the distributed security benefits.
