Modifying or upgrading a Hyperledger Fabric application
The design of a generic Hyperledger Fabric application presented in Chapter 5, Exposing Network Assets and Transactions, offers hints about the types of upgrades that may be required during its lifetime. Let us examine the various ways in which the requirements of a Fabric network and its users change over time:
- Software updates: Changes and upgrades are an integral part of software maintenance. More frequently, modifications are required to fix bugs, performance inefficiencies, and security flaws (for example, think of the Windows Update Service). Less frequently, though almost equally inevitably, major design changes must be made to software to handle unanticipated challenges. Also, given that most applications depend on other (third-party) software, any upgrades in the latter trigger corresponding changes in the former. Think of Windows Service Packs as an analogy. In the Hyperledger Fabric world, you as an application developer or...
