add blockmatrix samples

[joshua-roberts]

We should create a folder in the project that contains a complete end to end demo of the blockmatrix fabric integration and a tutorial of the demo.

The file structure should look like this:

/path/to/fabric
    - blockmatrix-samples/
        - bin/
        - config/
        - network/
        - chaincode/
        - client/
        - Makefile

• the bin and config folders can be taken from fabric-samples.

It will have four main components:

• network: a sample fabric network from fabric-samples without the org3 scripts.
• chaincode: sample chaincode to put, get, and delete key value pairs. Will be installed on both channels.
  • put: take a json array of key value pair and put those pairs on the ledger. For now keys and values will be only strings.
    • json in Go: https://www.sohamkamani.com/golang/json/
    • use PutState to put values on ledger
  • get: take a single key as a string and returns the value associated with it
  • delete: takes an array of keys as strings and deletes them from the ledger
• client: the blockmatrix client application to visualize the blockmatrix
• Makefile: a Makefile to aid in the building and running of the samples

We can use the test network from fabric-samples without the org3 scripts.

In the make file, we'll need to call the make-native and make-docker targets of the root Makefile. Then copy the contents of the generated build/bin/ folder to the blockmatrix-samples/bin folder which should be created in the during the build process. We'll also need a way of getting the fabric-ca-client and fabric-ca-server binaries into the bin folder using curl -sSL https://bit.ly/2ysbOFE | bash -s -- 2.2.8 1.5.3

Once these things are done, I'll go in and add the chaincode and demo client. Then we can do end to end testing.

Finally, we should create an in depth tutorial on building, running and using the blockmatrix.
