Lab 02 – Writing Chaincode

V2.2

Introduction

Now that you have a running business network, you can write, install, and run smart contracts, called chaincode, to interacts with your blockchain. Chancode makes up your blockchain application and provides the only way for users to read from, and append to, the blockchain.

In this lab you’ll examine several chaincode files, run the sample chaincode presented in your textbook, and run tests on the chaincode to assess its functionality.

Lab Deliverables:

To complete this lab, you must create a Lab Report file and submit the file in iLearn. The Lab Report file must be a Microsoft Word format (.docx), and have the filename with the following format:

BLCN532_SECTION_STUDENTID_LASTNAME_FIRSTNAME_Lab02.docx

• SECTION is the section number of your current course (2 digits)
• STUDENTID is your student ID number (with leading zeros)
• LASTNAME is your last name
• FIRSTNAME is your first name

To get started, create a Microsoft Word document (.docx) with the correct filename for this lab. You’ll be asked to enter text and paste screenshots into the lab report file.

NOTE: All screenshots MUST be readable. Use the Ubuntu Screen Capture utility (see the lab video.) Make sure that you label each screenshot (i.e. Step 2.1.3) and provide screenshots in order. For commands that produce lots of output, I only want to see the last full screen when the command finishes. Provide FULL screenshots, NOT cropped images.
