Dicussion :- Contrasting local and public test blockchains

In chapter 4, the author discusses different options for testing blockchain applications. For our course, we have chosen to use Ganache, a local test blockchain. Explore some of the advantages and disadvantages of using local and public blockchains to test apps and contrast the two options.  

• Create a new thread 
  • Contract the advantages and disadvantages of using local and public blockchains to test applications.
  • Explain how each advantage and disadvantage impacts blockchain application development, and why each is important to a successful blockchain implementation.

I’m interested to read what YOU learned from this week’s reading. Do NOT submit a research paper. Tell me what you think.

• Think of three questions you’d like to ask other students and add these to the end of your thread.
  • The questions must be taken from material you read in Chapter 1 or 2, and each question should start a discussion topic.
  • You’re not trying to test each other, but you are trying to start a discussion.

ALL threads and comments must be substantive AND ORIGINAL. (I'm looking for about a paragraph - not just a short answer.) Do not plagiarize!! Use your own words.
