Blockchain Security for Big Businesses Using Tried-and-True Methods

A foundational step in securing blockchain is selecting the appropriate blockchain architecture. Organizations must carefully evaluate whether a public, private, or consortium blockchain best suits their needs. Large organizations often prefer Private and consortium blockchains as they allow controlled access, limiting participation to trusted entities. This reduces the risk of unauthorized activity and ensures that data remains secure within a closed network. Role-based access controls further enhance security by restricting permissions based on the user's function, ensuring authorized personnel only perform sensitive operations.
