A Barrier Chain refers to a blockchain system designed to enhance security and performance by limiting access to certain functionalities or data. This setup creates layers or barriers that regulate who can interact with specific blockchain features or information.

The primary motivation behind a Barrier Chain is to protect sensitive data while still allowing necessary interactions. For instance, only authorized parties can access confidential information or execute specific transactions, which helps prevent unauthorized access and potential vulnerabilities. Barrier Chains can also improve scalability. By segmenting access, these systems can handle more transactions efficiently.

Instead of having every participant involved in all activities, only those with permission can engage with certain functions, streamlining the process. These chains often find use in applications requiring strict access controls, such as finance, healthcare, or supply chain management, where protecting sensitive information is paramount. Overall, Barrier Chains serve as an innovative approach to enhance security and functionality in blockchain networks.
