Network isolation refers to the practice of separating a blockchain network or its components from external networks. This is often done to enhance security and reduce the risk of attacks or unauthorized access. By isolating a network, sensitive operations can be conducted without exposure to potential threats from outside sources.In many cases, network isolation is employed by organizations and projects that handle large volumes of sensitive transactions or data. It can involve using private networks or specialized configurations that restrict access to specific users or nodes. This helps protect against hacks and ensures that the integrity of the blockchain is maintained.Additionally, network isolation can facilitate regulatory compliance by limiting data exposure and allowing for more secure handling of user information. Overall, this practice plays a crucial role in maintaining the security and efficiency of blockchain operations.
