Running the simulator

1. Head into the directory Source_Code and open file main.cpp.
2. In lines 19-35 set the parameters for the simulation. The variables have their standard meanings. The boolean variable invalid is supposed to be set true only when you want a peer to generate invalid blocks
3. Open terminal and run the make command as shown:

180050007_180050082_180050098/Source_Code $ make

4. This generates a file named output. Run the output script as shown:

180050007_180050082_180050098/Source_Code $ ./output

5. This generates peer_info.txt files for every peer which contains the time of arrival of every block in the tree.
6. 4th step would also generate a file tree.txt which contains the description of the edges of the global blockchain tree.
7. If the invalid is set to True, the program also prints the block IDs of all the invalid blocks.
8. To visualise a tree, we have also provided a python script showTree.py which opens tree.txt and prints a tree on the terminal itself. This can be done in the following manner:

180050007_180050082_180050098/Source_Code $ pip3 install treelib
180050007_180050082_180050098/Source_Code $ python3 showTree.py
