Before you start mining for the first time, you need Create Account, used to collect HAC mining rewards.

With fullnode to mining

Before starting full node mining, you need to run full node and wait for all block data synchronization to complete.

First of all, you need to configure the full node according to the Hacash Config Instruction, Modify the configuration to enable mining. The hacash.config.ini file is a required configuration file for a Hacash full node program and contains various configurations. You need to modify the three parameters under [miner] in the configuration file:

[miner]
enable = true
reward = 1AVRuFXNFi3rdMrPH4hdqSgFrEBnWisWaS
message = unknown

Where, delete the semicolon before enable = true indicates that mining is started (semicolon ';' indicates that the comment item does not take effect, and the same applies to other item configurations such as HACD mining).

The string value of the reward parameter is the account address of Hacash, which is used to receive the monetary rewards generated by mining. This address must be generated through a wallet, in a specific format, using an online wallet, a password that is kept strictly confidential and backed up, or a randomly created private key. message is the identifier of the block announcer, which is generally only required for mining pools.

Then, enable the configuration of the API service of the full node, so that the mining terminal can connect to the full node and get the latest mining data and block information:

[server]
enable = true
listen = 8081

Note: Need to wait for the block synchronization to complete, then modify the configuration, and then restart the fullnode for the mining configuration to take effect.

Start mining

Then, download the poworker (HAC PoW miner worker) program for the corresponding operating system in the Hacash Software Release Center and follow the instructions in Hacash Configuration Instructions Modify the configuration of the mining program poworker.config.ini:

connect = 127.0.0.1:8081
supervene = 4

The connect parameter indicates the IP and port of the full node API service to be connected, and the 'supervene' parameter indicates how many threads of mining are enabled at the same time, which is generally consistent with the number of CPU cores on your computer and can exert maximum computing power. For example, if your computer has 2 CPU cores, change supervene = 8 to supervene = 2, if it has 4 cores, change it to supervene = 4, and so on. At this point, the computer's CPU utilization is 100%. It is generally recommended to set aside one core for other calculations: 4 cores for 3 cores and 8 cores for 7. It can also be set freely according to your situation, the lower the value, the lower the CPU utilization. This value doesn't support decimals, has a minimum of 1, and isn't recommended to be larger than the number of CPU cores on your PC.

If there are multiple machines mining at the same time on the intranet, multiple devices can be connected to the same full node to establish a computing power cluster.

Run the hacash_poworker program from the command line or by double-clicking, and you can see the following prints:
