For OSx instructions:

Installing Komodo on Ubuntu/Debian


Currently, you will need:

  • Linux (easiest with a Debian-based distribution)
  • 64-bit
  • 4GB of free memory (Minimum 8GB RAM recommended)

Get Started

Log in as the user to your system, and issue these commands to make sure your Linux machine is up to date.

sudo apt-get update
sudo apt-get upgrade -y

Install the dependency packages:

sudo apt-get install build-essential pkg-config libc6-dev m4 g++-multilib autoconf libtool libncurses-dev unzip git python zlib1g-dev wget bsdmainutils automake libboost-all-dev libssl-dev libprotobuf-dev protobuf-compiler libqrencode-dev libdb++-dev ntp ntpdate nano software-properties-common curl libevent-dev libcurl4-gnutls-dev cmake clang libsodium-dev -y

Installing Komodo

cd ~
git clone
cd komodo
git checkout beta

-j8 uses 8 threads - replace 8 with number of threads you want to use or nproc variable

./zcutil/ -j$(nproc)

This can take some time.

When it is finished, let's create komodo.conf

cd ~
mkdir .komodo
cd .komodo
nano komodo.conf

Add the following lines to the komodo.conf file (replace rpcuser and rpcpassword)

  • Press CTRL+O to save the changes.
  • Press CTRL+X to exit nano editor.

Now you can start komodod daemon to sync with the network

cd ~
cd komodo
./src/komodod -addnode= -daemon

You might see some outputs in terminal where you started komodod daemon. So, open a new tab or new terminal window and go to Komodo data directory to see updated logs of Komodo:

cd ~/.komodo/
tail -f debug.log

After tail command it will start showing logs update to you as it syncs with the network. If you want to terminate this command just press CTRL+C.

In another terminal window you can go to Komodo source directory and use komodo-cli command to check the latest update info. like:

cd ~/komodo/src/
./komodo-cli getinfo

This will show you latest info of blockchain and wallet like this:

    "version" : 1000550,
    "protocolversion" : 170002,
    "KMDversion" : "0.1.0",
    "notarized" : 186670,
    "notarizedhash" : "000000308845da840ab9af6c1e09dc02f3118683df065b5ec00b05c9bd58cdae",
    "notarizedtxid" : "6723a10ef4fceab230d4245305d1ed2a916e435abb83269c20daad9bbefd3f0e",
    "notarizedtxid_height" : "mempool",
    "notarized_confirms" : 0,
    "walletversion" : 60000,
    "balance" : 0,
    "interest" : 0,
    "blocks" : 186773,
    "longestchain" : 308867,
    "timeoffset" : 0,
    "tiptime" : 1486411069,
    "connections" : 8,
    "proxy" : "",
    "difficulty" : 1624278.62879530,
    "testnet" : false,
    "keypoololdest" : 1482746526,
    "keypoolsize" : 101,
    "paytxfee" : 0.00000000,
    "relayfee" : 0.00001000,
    "errors" : ""

in this output when you see "blocks" and "longestchain" values showing same, your wallet is in full sync.

Updating Komodo installation to latest version

If you had already installed Komodo from it's source code on your machine, and need to update to latest version just do these commands

cd ~/komodo/src/
git checkout beta
git pull
make -j$(nproc)

if you get any error executing make command, then do these commands:

cd ~/komodo/
git checkout beta
git pull
./zcutil/ -j$(nproc) method will take longer as compare to make command. make command should work every time for you, butin case it doesn't just use method.

IMPORTANT: Backup your wallet

We can not stress enough to take a backup of your wallet.dat file time to time. Here's the reason why:

  • When you send some funds from an address, sometimes the funds used from the unspent transaction outputs (utxo) leaves a change behind. This change doesn't go back to the same address the funds sent from. This change goes to a new address. And this new address is stored in the wallet.dat file located in Komodo data directory on your machine.
  • Sometime your wallet.dat file may got corrupted. It's always good to have backup handy.

If you are not sure when to take backup of your wallet.dat file, just take backup of it according to how often your use. If you use it regularly, then just take a backup of your wallet.dat file at then end of day. If not so often then maybe twice a week or depending on your use adjust your time period of taking backup.

You can find your wallet.dat file under linux at ~/.komodo/wallet.dat.

To backup you can take a copy of this file and make archive of it.

# To copy
cp -av ~/.komodo/wallet.dat ~/wallet.dat

# To rename file
mv ~/wallet.dat ~/wallet_backup_DATE_HERE.dat

# example
mv ~/wallet.dat ~/wallet_backup_21May2017.dat

# To make archive
tar -czvf ~/wallet_backup_21May2017.dat.tgz ~/wallet_backup_21May2017.dat

Installing Komodo on OSX


Ensure commandline tools from apple/xcode are installed. Issue the following command in a terminal.

xcode-select --install

brew is needed to install dependencies. If you have latest brew installed in your system already, skip this and install the deps directly.

/usr/bin/ruby -e "$(curl -fsSL"

These are the dependencies needed to install with brew.

brew update
brew upgrade
brew tap discoteq/discoteq; brew install flock
brew install autoconf autogen automake
brew install gcc@8
brew install binutils
brew install protobuf
brew install coreutils
brew install wget

Clone the Komodo repository

git clone

Get the Zcash params:

cd komodo

Compile Komodo

git checkout dev
./zcutil/ -j8

This can take some time, so let's create a configuration file in the mean time using a new terminal.

Create configuration file

The configuration file should be created in the following directory:

~/Library/Application\ Support/Komodo

Create the directory if it's missing:

mkdir ~/Library/Application\ Support/Komodo

and create the configuration file by entering this in terminal:

echo "rpcuser=komodouser" >> ~/Library/Application\ Support/Komodo/komodo.conf
echo "rpcpassword=`head -c 32 /dev/urandom | base64`" >> ~/Library/Application\ Support/Komodo/komodo.conf
echo "txindex=1" >> ~/Library/Application\ Support/Komodo/komodo.conf
echo "bind=" >> ~/Library/Application\ Support/Komodo/komodo.conf
echo "rpcbind=" >> ~/Library/Application\ Support/Komodo/komodo.conf

Run Komodo

If the build went well, run komodo:

cd ~/komodo/src
./komodod -daemon

To track progress of downloading the Komodo blockchain:

tail -f ~/Library/Application\ Support/Komodo/debug.log

or get info with the getinfo command:

./komodo-cli getinfo

Installing Komodo on Windows 64-bit


  1. First download komodo windows binaries and place the files in a new folder on the Desktop called kmd ('C:\Users\YourUserName\Desktop\kmd') .

Open a Command Prompt for the following steps.

  1. Next we'll create the Komodo directory in the AppData directory.

mkdir "%HOMEPATH%\AppData\Roaming\Komodo"

  1. Next we will create our komodo.conf file.

notepad “%HOMEPATH%\AppData\Roaming\Komodo\komodo.conf”

When Notepad opens click Yes to create the komodo.conf file. Copy the information below and paste it into Notepad.
















After pasting, save and exit Notepad.

  1. So now that you have created your komodo.conf file you are ready to download the zk-snark proving key and; verifying key.

While the keys are downloading let's paste following command to create the directory for ZcashParams: HTML

mkdir “%HOMEPATH%\AppData\Roaming\ZcashParams”

One the keys have finished downloading we'll paste this command to move the keys to our newly created ZcashParams directory: HTML

move “%HOMEPATH%\Downloads\sprout-proving.key” “%HOMEPATH%\AppData\Roaming\ZcashParams” && move “%HOMEPATH%\Downloads\sprout-verifying.key” “%HOMEPATH%\AppData\Roaming\ZcashParams”

  1. Now we can run komodod.exe HTML


  1. Komodod should start synching. You can check progress by running HTML

"%HOMEPATH%\Desktop\kmd\komodo-cli.exe" getinfo

  1. To stop komodod, run:

"%HOMEPATH%\Desktop\kmd\komodo-cli.exe" stop
