 +====== Chia Network ======
  
 +<callout type="warning" icon="true">The following page was built and tested on Linux!</callout>
 +
 +**There are public nodes for Chia, HDDCoin, STAI and BPX Network where you can try connecting to if experiencing connection issues: [[user:zyzonix#public_blockchain_nodes|Zyzonix - Public Blockchain Nodes]]**
 +===== Install Chia-Blockchain from Repository =====
 +
 +To install the [[https://chia.net/|Chia-Blockchain]] software from a repository on Debian, add Chia's official repository:
 +
 +**1.** Install required packages:
 +<code bash>apt-get install ca-certificates curl gnupg</code>
 +
 +**2.** Get the repositories GPG key:
 +<code bash>curl -sL https://repo.chia.net/FD39E6D3.pubkey.asc | sudo gpg --dearmor -o /usr/share/keyrings/chia.gpg</code>
 +
 +**3.** Paste repository URL to sources list:
 +<code bash>echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/chia.gpg] https://repo.chia.net/debian/ stable main" | sudo tee /etc/apt/sources.list.d/chia.list > /dev/null</code>

 +===== Auto start Chia-Blockchain on system startup =====
 +
 +It is possible to start Chia-Blockchain and forks of it automatically after system startup through a system service on Linux. 
 +This guide shows how to add a system service for Chia under ''/etc/systemd/system/'':
 +
 +**1.** Create the service file:
 +<code bash>nano /etc/systemd/system/chia.service</code>
 +
 +**2.** Paste the content:
 +
 +<callout type="warning" icon="true"> **The content of the service file depends on the way you installed Chia-Blockchain and on what you would like to run automatically (Node, Timelord, ...) ** </callout>
 +
 +If installed chia via ''.deb'' package use this content:
 +<code bash>
 +[Unit]
 +Description=Chia Blockchain Node Autostart
 +Wants=network-online.target
 +After=network.target network-online.target
 +StartLimitIntervalSec=0
 +
 +[Service]
 +Type=forking
 +Restart=always
 +RestartSec=1
 +User=root
 +ExecStart=/usr/bin/chia start farmer -r
 +ExecStop=/usr/bin/chia stop all -d
 +
 +[Install]
 +WantedBy=multi-user.target
 +</code>
 +
 +Otherwise if installed chia from source:
 +<code bash>
 +[Unit]
 +Description=Chia Blockchain Node Autostart
 +Wants=network-online.target
 +After=network.target network-online.target
 +StartLimitIntervalSec=0
 +
 +[Service]
 +Type=forking
 +Restart=always
 +RestartSec=1
 +User=root
 +Environment=PATH=/usr/local/chia-blockchain/venv/bin:${PATH}
 +ExecStart=/usr/bin/env chia start farmer -r
 +ExecStop=/usr/bin/env chia stop -d all
 +
 +[Install]
 +WantedBy=multi-user.target 
 +</code>
 +
 +You can edit the line ''ExecStart'' if you wish to start something different than Node or Timelord, use ''chia start --help'' to view all possible start arguments.
 +
 +For example to start Node and Timelord edit ''ExecStart'' and change it to (only works when installed from source):
 +<code bash>ExecStart=/usr/bin/env stai start farmer timelord -r</code>
 +
 +This services were tested for [[https://github.com/Chia-Network/chia-blockchain|Chia-Blockchain]], [[https://github.com/STATION-I/stai-blockchain|Stai-Blockchain]] and [[https://github.com/HDDcoin-Network/hddcoin-blockchain|HDDCoin Network]].

 +===== Plotting in RAM (Linux) =====
 +
 +<callout type="warning" icon="true">At least **''512GB''** RAM is required for RAM plotting.</callout>
 +
 +This section show how to create plots in RAM, which is extremely fast and doesn't wear out NVMe's like disk plotting does.
 +Also with older hardware (from 2014) it is possible to create plots in under 30 min. 
 +
 +==== Using bladebit ====
 +
 +<callout type="warning" icon="true">**Remind** that this guides uses the official ''bladebit'' plotter from Chia that is only able to plot ''k32'', if you wish to plot bigger plots have a look at one section below!</callout>
 +
 +Nevertheless it is recommended to have a NVMe or SATA SSD installed where the plot can be saved after plotting. Otherwise the time of writing the plot to a hard disk would make this way of plotting very expensive because server hardware clearly consumes more energy than other hardware. 
 +
 +The best way of RAM plotting is plotting while moving a already plotted other plot to a hard disk. So when shutting down the plotting machine keep one plot on the SSD storage, this plot can be moved to the a HDD next time while plotting a new plot in RAM after the next startup.
 +
 +To create plots in RAM use this command:
 +<code bash>
 +chia plotters bladebit ramplot -r <count-of-threads> -c <contract_NFT-only> -n <number-of-plots-to-be-plotted> -d </path/to/SSD>
 +</code>
 +
 +**Parameters:**

 +<panel>
 +^ Parameter  ^ Setting                                                      ^ Example         ^
 +| -d         | Destination path to temporary SSD storage (NVMe/SATA)        | ''/mnt/SSD1''   |
 +| -r         | Threads to use (Depends on CPU)                              | ''250''         |
 +| -n         | Count of plots to plot                                       | ''4''           |
 +| -c         | Contract ID (if plotting NFT plot) (starts with ''xch...'')  | ''<contract>''  |
 +</panel>
 +</WRAP>
 +
 +==== Using tmpfs ====
 +
 +First create a "static" ''tmpfs'' with [[https://wiki.debian.org/RamDisk|ramdisk]] in ''/etc/fstab'' though adding the following line:
 +<code bash>
 +ramdisk  /ramdisk  tmpfs  defaults,size=495G,x-gvfs-show  0  0
 +</code>
 +Adjust the value of ''size'' on your needs! **There should always be some space left for the OS!**
 +
 +After updating the ''fstab'' file run the following command to mount the ''tmpfs'' for the current session, from now on the OS will mount it automatically after each boot.
 +<code bash>mount -a</code>
 +
 +Finally you can use the default Chia plotter to create the plots. **Remind that it will be faster than on a NVMe but much slower than bladebit!**
 +<code bash>
 +chia plots create -k33 -b200000 -c <contact-id> -t /ramdisk/ -d </path/to/final/directory> -r <count-of-threads> -x
 +</code>
