The goal of this project is generate bitcoins with the required number of leading zeros using Erlang actor model.
- Created a distributed bitcoin mining application based on the Erlang actor model, in which multiple actors distributed over three client nodes generates hashed bitcoin strings and compares the number of leading zeroes in their SHA256 cryptographic hash function.
Steps 1:
1. Sever -
- Give name to the server along with the cookie:
erl -name akash@{ipaddress} -setcookie {cookiename}
2. Client Supervisor-
- Give name to client along with the cookie:
erl -name akash@{ipaddress} -setcookie {cookiename} #same cookie name
Steps 2:
1. Sever -
- Compile and Call the start method -
c(bitcoinMinerServer).
bitcoinMinerServer:start(MinNumberOfLeadingZeros).
2. Client Supervisor-
- Compile and Call the start_link method -
c(bitcoinMinerClientNodeSup).
bitcoinMinerClientNodeSup:start_link({host name}).
eg. hostname : akash@{ipaddress}
The following output was obtained while mining for coins with 4 leading 0's.

CPU time: (Time in usermode) + (Time in kernel mode) = 30.028 Real time: 8.97 Maximum number of machine/Nodes : 3 Maximum numbe of Actor user: 3 * 500
1) bitcoinMinerServer Contains functions for starting the 3 client nodes by sending start processing message
with{minleadingzeros} value.
2) bitcoinMinerClientNodeSup Contains functions to spawn 500 actors and supervises them on a single node using
actor model.
3) bitcoinMinerClientActor/bitcoinMinerActorProcess: These files contains the core business logic of mining
bitcoin methods. bitcoinMinerClientActor spawns the logic process and also calls the start_link method of
bitcoinminerActorProcess method upon recieving the message from parent node. bitcoinMinerActorProcess responsible
to generate the hashed strings with SHA256 by concating the gatorlink Id with random string and chevks for the
leading zeros. Upon finding the required numbe of zeros. It sends a message back to client node supervisor
which inturn relays the message the "foundCoin" message to the Server.
4) calstatsScheduler Contains function to start the CPU times.
