CS 765 Assigment-2

Environment:

Make sure python v3 is installed on your system.

Running instructions:

• Navigate to code directory:

$ cd code/

For stuborn mining without any attacker: navigate to stubborn_mining directory.

For mining with attackers: navigate to selfish_mining directory.

• basic command to run event simulator:

$ python3 main.py --peers [PEERS] --z0 [Z0] --z1 [Z1] --transaction-mean-gap [TRANSATIONMEANGAP] --att1 [ATT1] --att2 [ATT2]

• for printing blockchain:

$ python3 main.py --peers [PEERS] --z0 [Z0] --z1 [Z1] --transaction-mean-gap [TRANSATIONMEANGAP] --att1 [ATT1] --att2 [ATT2] --print-blockchain

• for visualizing the blockchain:

$ python3 main.py --peers [PEERS] --z0 [Z0] --z1 [Z1] --transaction-mean-gap [TRANSATIONMEANGAP] --att1 [ATT1] --att2 [ATT2] --visualize-blockchain

**Note: If u want to print and visualize, add both --print-blockchain and --visualize-blockchain flags to the basic command (order dosen't matter).

PEERS - No.of peers

Z0 - z0 fraction of low speed distribution

Z1 - z1 fraction of low CPU speed distribution

TRANSACTIONMEANGAP - transaction mean time.

ATT1 - attacker 1's hashing power ATT2 - attacker 2's hashing power

• to visualize graph of nodes: $ python3 graph.py --generate
