Block Chain Development discussion 5
Chapter 8 describes the process of maintaining blockchain apps after deployment. Create a new thread, choose one aspect of app maintenance from the material in chapter 8, and describe the life cycle problem and how addressing your chosen problem in a blockchain environment differs from a traditional application development life cycle. Then think of three questions youd like to ask other students and add these to the end of your thread. The questions should be taken from material you read in Chapter 7 or 8. Youre not trying to test each other, but you are trying to start a discussion.
You must do this following:
1)Create a new thread.As indicated above, choose one aspect of app maintenance from the material in chapter 8, and describe the life cycle problem and how addressing your chosen problem in a blockchain environment differs from a traditional application development life cycle. Then think of three questions youd like to ask other students and add these to the end of your thread. The questions should be taken from material you read in Chapter 7 or 8. Youre not trying to test each other, but you are trying to start a discussion.

Promotion Process
Promotion
Process
Constraints
Every code change is tied to a change request
Developers sign their modification using GPG
Master branch integrity is preserved by the
pull request process
The pipeline builds and tests the code for pull
requests
The pipeline publishes the smart contract to
the artifact repository when changes are
tagged
Each organization receives a notification when
a new version is available
