Mining stratum for Spacecoin, Komodo, and other komodo smartchains.


Differences between this and Z-NOMP

  • This is meant for mining Spacecoin, Komodo, and Komodo smartchains
  • Founders, Treasury, and other ZEC/ZEN specific stuff is removed


Please be sure to backup your ./coins and ./pool_configs directory before upgrading

Kill your running pool (CTRL-C)

cd knomp
git pull
npm install
npm start

Install Daemon

Some initial setup

# The following packages are needed to build both Spacecoin and this stratum:
sudo apt-get update
sudo apt-get install build-essential pkg-config libc6-dev m4 g++-multilib autoconf libtool ncurses-dev unzip git python python-zmq zlib1g-dev wget libcurl4-openssl-dev bsdmainutils automake curl libboost-dev libboost-system-dev libsodium-dev jq redis-server nano -y

Now, let's build Spacecoin

git clone
cd spacecoin
zcutil/ -j8
strip src/komodod
strip src/komodo-cli

Now, let's start Spacecoin

cd ~/spacecoin/src

Install Pool

Once SPACE is synced up we can configure the stratum.

We need node and npm installed

cd ~
curl -sL | sudo -E bash -

Now, let's build our stratum and run it. This will install the pool. Then you need to configure knomp and the SPACE pool with the rpcuser/pass from the SPACE.conf file, as well as your pool/fees address.

git clone
cd knomp
npm install
cp config_example.json config.json
# then configure it
nano config.json
cp pool_configs/example/space.json pool_configs/space.json
# then configure it
nano pool_configs/space.json

Finally we are ready to start the pool software

npm start

If all went well knomp should start without error and you should be able to browse to your pool website on your server via port 8080.

More Info:

Disable Coinbase Mode

This mode uses -pubkey to tell the daemon where the coinbase should be sent, and uses the daemons coinbase transaction rather then having the pool create the coinabse transaction. This enables special coinbase transactions, such as ac_founders and ac_script or new modes with CC vouts in the coinbase not yet created, it will work with all coins, except Full Z support described below.

To enable it, change the value in the coins/space.json to "disablecb" : true

The pool fee is taken in the payment processor using this mode, and might not be 100% accurate down to the single satoshi, so the pool address may end up with some small amount of coins over time.

Payment Processing

Please note that the default configs generated are for solo mining. If you wish to create a public pool please modify the configs like in this example config

There is now a config option you can add to your pool_configs/coin.json to toggle making an attempt at a payment upon pool startup.

"paymentProcessing": {
    "payOnStart": true,

Invalid Worker Addresses

You can add an option to your pool_config to have any miners that mine with an invalid address (if they somehow get through) to pay out to an address of your choosing


Sapling and Sapling Payment Support

In coins/space.json file:

"privateChain": true,
"burnFees": true,
"sapling": true

In pool_config:

"zAddress": "zsPoolsSaplingAddress",
"walletInterval": 2,
"validateWorkerUsername": true,
"paymentProcessing": {
    "minConf": 5,
    "paymentInterval": 180,
    "maxBlocksPerPayment": 20,
