Teku Installation

You'll need to create a few folders in the Home directory to store the keystore and password.

1) Create a new folder in your Home directory called "keystores-teku"

2) Copy and paste your keystore file into that folder, as shown below

2) Navigate back to the Home directory and create another folder called "passwords-teku"

3) Create a new text file where you will enter your keystore password

You can create a new text file by clicking on the icon in the bottom left hand corner of Ubuntu, then searching "Text Editor" and click this icon

4) Enter your keystore password (nothing more, nothing less) as shown below:

5) Save the file as the EXACT same name as the keystore, but ending in .txt rather than .json

If your keystore file is named: keystore-m_12381_3600_0_0_0-1646941924.json

Your password file is named: keystore-m_12381_3600_0_0_0-1646941924.txt

6) Save the password text file in the "passwords-teku" file as shown below:

Note: The last two lines of this code need to be updated with your specific information.

• --validator-proposer-default-fee-recipient

  • Input the address where you'd like to receive fees

• --validator-keys=

  • This points to the location of your keystore and password. You need to update both parts with your specific file names (they are separated by the colon)

  • The keystore name in this example is:

    • keystore-m_12381_3600_0_0_0-1646941924.json

  • The password file name is:

    • keystore-m_12381_3600_0_0_0-1646941924.txt

Copy this code into the terminal after updating last 2 lines:

Teku Startup - Kiln

If you maximize the terminal window, it will be easier to read.

Somewhere in the startup text, you should see "Loaded 1 Validators: XXXXXXX" as seen at the bottom of the previous screenshot

Once you have successfully loaded the keystore, you're ready to deposit the 32 Kiln ETH.
