first review of the exercises

[MSilva95]

Some things you need to do:

• modify the titles of the exercises in the readme. Some exercises have the same name repeated mainly in quest 1 several have the name signer, I advise you to check them all. -The exercise "Retrieve Transaction In and Out" on line 18 is not quite clear what is asked to return.
• The exercise "Retrieve Transaction Value" What is note bene? is it Hint?
• The exercise "Send transaction to peer" Is the audit only one question?
• The exercise "Increment" is the title increment or Merkle tree?
• The exercise "Fun and Profit" line 8 is not very clear what is asked to return.

I would like to ask you to always keep the same structure/format for readmes

Title

Instructions

Usage

Relevance (if needed)

Notions

• all readmes end with a blank line at the end
• the name of the exercises must be the same everywhere to avoid confusion. in the exercise in the test and in the title of the readme

Questions:

• Do we really need to have "Relevance" in the exercises?
• Do you think it will be necessary some form of introduction to the blockchain? a video or a readme explaining what it's about?

Thanks for the review.

• Nota bene is information that is not necessarily useful for the resolution, but I will convert it as hint for clarity
• Yes, there is only one question necessary. I can expand to keep a similar format
• Relevance is there to give a bit of context of why we are doing a particular exercice. If you don't see the benefit, I can remove it and add an introductory line when necessary
• I'm counting on them having a general idea of what a blockchain is and to understand details along the exercises, but I will add introductory videos.
