The goal of this project is to build a mining system that can find strings which when encoded using SHA-256 hashing function contains "n" number of leading zeroes where n is specified as input. This system as the value of n grows becomes computationally intensive and this is efficiently handled by using Actor Model in Erlang where the work or process is scaled across various threads. This increases the utilization of he CPU and thus efficiency of the mining system.

erl -name <username>@<IPAddress> #Creating a node

c(mining.erl). #Compile Erl file

mining.begin_erlserver(). #Starting a server in the node

mining:calculator('<username>@<IPAddress>',<workunits>). #Running the Miner

 username: Your sytems username
 IPAddress: Your systems Ip address
 worknits: Desired number of workers

Hashing performed on a string size of 500 and finding hashes with 4 leading zeroes.

From our test we found our code works best with 1000 actors with CPU to Real time ratio of 8.31216. So we wll further perform tests using 1000 actors on a string size of 150 to find a coin with highest number of leading zeroes.

CPU time: 18569145 ms Real Time: 223372 Ratio( CPU to Real time) : 8.31216

We found a bitcoin with 7 leading zeroes with 1000 workers on a string of length 150.

The largest number of working machines we were able to test our code is 8
