Overview
The PoW Miner helps get the next block added to the VeriBlock blockchain. It will connect to a local instance of NodeCore, using UCP on port 8501.
You can run the PoW Miner as an individual, or connect to a pool (See: HowTo_run_and_connect_to_PoW_Miner_pool)
This page explains how to run the PoW Miner as an individual.
Note that PoW Mining is separate from Proof-of-Proof (PoP) Mining. Both reward VBK tokens, but are different operations. (See: HowTo_run_PoP_Miner, PoW_vs_PoP_Mining)
Steps
Note: If you are having trouble running nodecore-reference-pow on linux, you may need to make nodecore-reference-pow executable: chmod a+x nodecore-reference-pow
- Ensure that nodecore is running (see: HowTo_run_NodeCore)
- In the NodeCore CLI, run the "startpool" command. This will start the UCP NodeCore protocol on port 8501, which the miner needs.
- Unzip nodecore-reference-pow.zip
- In the bin folder, if Windows then run nodecore-reference-pow.bat, if linux then run nodecore-reference-pow
- Enter the input arguments
- How many threads would you like to mine on? --> such as 2 or 8.
- What host:port would you like to connect to for mining? --> 127.0.0.1:8501
- What address would you like to mine to? --> the default address for your local instance of nodecore, such as "V6RRxmzJAhLkeWTzcFzQkQEgP2hC1e". Run getinfo in the commandline to see the default address.
The Startup console output will prompt for input:
If running a local NodeCore instance, then use the NodeCore CLI to run the command: startpool How many threads would you like to mine on? 2 What host:port would you like to connect to for mining? (Use the port for UPC. Default 127.0.0.1:8501) 127.0.0.1:8501 What address would you like to mine to? V34RwWk5CEp5uE8L4SSpJWcwN29dKu
And then dump output like:
Note: server capabilities are 10011111111
Authentication successful!
Mining subscription successful!

How to run a solo miner
In the NC_CLI, connect to a NodeCore instance and run the startsolopool command
startsolopool VHHqCkYqpJydXZB2uUs7msSKK5c2Xp
Expected response:
By default, your pool homepage will be available in a web browser at:
http://127.0.0.1:8500
And a VeriBlock Proof-of-Work (PoW) miner can be pointed to:
http://127.0.0.1:8501
Remember that by default a solo pool mines to your default address!
You can view that address with the command: getinfo
You may also find the following commands useful ('help' for syntax):
stoppool (Stops the built-in pool service in NodeCore)
getbalance (See the balances of all of your addresses)
setdefaultaddress (Sets the default address of a NodeCore instance)
startcpuminer (Attempts to start the CPU PoW Miner in a new window)
200 success (142.7 ms)
Open up the PoW miner and run like normal (entering threads, host/port - probably the default 127.0.0.1:8501, and the username/address)
Example:
How many threads would you like to mine on? Default=1, Maximum suggested=8 1 What host:port would you like to connect to for mining? (Use the port for UPC. Default 127.0.0.1:8501) Using default = 127.0.0.1:8501 What username/address would you like to mine to? VHHqCkYqpJydXZB2uUs7msSKK5c2Xp Note: server capabilities are 10011111111 Authentication successful! Mining subscription successful!
You should see the miner running, and you should be able to view the local webpage: http://127.0.0.1:8500
FAQ
What is the reward for PoW Mining
35 VBK per block. If pool mining, then that reward will be split among the pool.
Will there be a GPU miner?
Yes.
Can I pass in arguments from the command line?
No, but you can set the properties in a config file such that it can be automated.
Add config file next to nodecore-pow.bat: nodecore_miner_pow.properties, and it will automatically pick up values and run:
#PoW Miner Configuration miner.threadcount=2 miner.address=VC8H4BPSKfKkg1CNK2yKr9P6MD9Zh7 miner.host=127.0.0.1:8501
Troubleshooting
The PoW Miner instantly crashes
Try running the PoW Miner from a command line (instead of just clicking "nodecore-pow.bat") such that you'll see an error output even if the original window exits.
The most likely cause of the window instantly shutting down is that the pool has not been started. If you're running an individual miner, then go to the NC_CLI and run "startpool". (See: NodeCore_CommandLine#startpool)
