Graft Supernode Mainnet - Simple step-by-step Supernode setup instructions for non-Linux users
a.k.a - Graft: Running a Supernode for Dummies Guide
- GraftNetwork - v1.7.5
- Supernode v1.0.4
by: yidakee (aka el_duderino_007)
This release is for main net launch.
This is a bare minimum install recommended for linux newbies and troubleshooting purposes.
This guide is not intended for linux educational purposes, rather a simple copy/paste procedure to get your Supernode up an running (safely) and see it working properly and learn basic Supernode management, to later be able to follow more advanced setup guides.
In future guide, I'll explain how to set up a Supernode with basic security issues addressed, basic hardening and setting the Supernode as a service so it survives a spontaneous reboot/crash.
Some screenshots show previous versions - be sure to use the correct version as of THIS guide -
Graft Network 1.7.5+ `graft-ng 1.0.4
- Any modern machine with at least 2GB per core, 2GB RAM recommended - some reports show it will work with 1CPU and 1GB RAM
- Current bandwidgth consuption ~300GB - 600GB per month
- VPS (virtual private server) recommended.

Start by selecting a VPS provider, spin up a node selecting Ubuntu 18.04.
Once you’ve fired up your node,
sshinto the server and perform typical maintenance
sudo apt-get update
sudo apt-get upgrade
- If this window shows up, select the first option
- We will now download the latest Graft release, and then the Supernode release
wget https://github.com/graft-project/GraftNetwork/releases/download/v1.7.5/GraftNetwork_1.7.5-ubuntu-18.04-x64.tar.gz wget https://github.com/graft-project/graft-ng/releases/download/v1.0.4/supernode.1.0.4.ubuntu-18.04.x64.tar.gz
- Lets have a look at the downloaded file. The compressed files show up in red
- Now, let's decompress the files and view the directories - these show up in blue
tar -zxvf GraftNetwork_1.7.5-ubuntu-18.04-x64.tar.gz tar -zvxf supernode.1.0.4.ubuntu-18.04.x64.tar.gz ls -la
- Next, lets enter the directory where the GraftNetwork binaries where decompressed into, and have a look inside. You will see there is a
graft-supernodebinary inside - do not use this one! The actual Supernode binary is inside /root/supernode.1.0.4.ubuntu-18.04.x64/
- To go back, simply issue
cdcommand, and you'll be back to the main /root/ directory.
Here is a handy Linux trick. Instead of writing
cd supernode.1.0.4.ubuntu-18.04.x64 try just typing
cd supeand then press Tab. Linux is smart enough to guess what you mean and will autocomplete for you ;)
Great! We’ve managed to install everything.
You now have;
graftnonded- syncs the blockchain, has interactive commands
graft-wallet-cli- wallet management, has interactive commands
supernode- RTA/supernode functions, non-interactive
These will be the only binaries you will use, do not use the others.
We could run
graftnodedand sync from scratch, but who wants to wait 5h doing nothing? Lets "cheat" by directly downloading the blockchain ans save lots of time.
graftnodedand wait a little for it to build the directories - give it 1 minute and then
cd GraftNetwork_1.7.5 ./graftnoded
A soon you see the bottom lines saying
Synced xxx/xxxxxx, you can type
Let's navigate to the directory where the blockchain lives in, delete the current one and download the most current up-to-date. The screenshot shows
testnetand steps are slightly different, but behaviour is identical
cd $HOME/.graft/ ls -la rm -r lmdb curl http://graftbuilds-ohio.s3.amazonaws.com/lmdb.tar.gz | tar xzf - cd lmdb && rm em* && rm lo* cd
Big shoutout to jagerman for keeping a publicly available copy of the blockchain. Thanks man, you rock!
Alternatively, you can use this torrent -> Torrent - Thanks @MV1879!
Brilliant! Now lets go back and start
graftnodedagain, and be almost immediately up to block height.
cd cd GraftNetwork_1.7.5 ./graftnoded
Enterto see the list of commands you can run to inspect the network. Enter
statusto double check your block height against the block explorer -> https://graft.observer
Supernodes run on cold wallet staking, so you should NOT keep your stake wallet on a live server. Especially with this barebone insecure server setup.
Next -> create a wallet for the Supernode stake
I will never use this wallet, so I'm ok with sharing the address and the mnemonic seed for the sake of the tutorial. Don't ever use this wallet address or mnemonic seed word list for yourself, as you're more than likely to lose any funds sent to it. Please keep your real mnemonic seed secret to only yourself at all times, never share it, never lose it!
Ideally, you should do this on a local and secure machine. If you absolutely need to, you can use the VPS, but after using the wallet dont forget to delete it. Keep your mnemonic seed in a very safe place in case you need to restore it in the future.
Open a new Terminal window, and fire up the
graft-wallet-clito generate a new wallet. Follow the instructions, and you will receive a wallet address and the 25 word mnemonic seed. Do not lose the seed!
Oh !!! I almost forgot... never, ever, lose your wallet seed !!
cd cd GraftNetwork_1.7.5 ./graft-wallet-cli
- Copy the wallet address to somewhere handy, you will need it a a bit to configure the supernode.
Now, let's start the Supernode
You will need to start a new Terminal session - if you close the current terminal window, it will kill the current process, in this case
graftnoded- in future tutorials we will explain how to use
screento solve this, but for now we're keeping it simple.
So, open a new Terminal session,
sshinto your VPS, and enter the Supernode directory
cd supernode.1.0.4.ubuntu-18.04.x64 ls -la
- We need to edit the
config.inifile to add in your stake wallet address - so have that handy! We will use
nano, one of many linux text editors. Once inside the file, use your arrow key to navigate to
wallet-public-address=and paste in your Supernode stake wallet address we generated earlier. Remember, this is a real mainnet, not a testnet tutorial, so please make sure the address starts with an
- To save the file, look at the bottom row of the screen and press
CTRL+xon your keyboard. It should now say
Save modified buffer?- simply type
yand press enter.
- Let's start the Supernode. Before we do so, lets quickly do a patch fix that should not be required in the future.
sudo apt install libboost-all-dev
- Start the Supernode to get it running without stake for now, to grab some final info.
- If you check back on
graftnodedTerminal, you should start seeing the Supernode announcements to the network
Now literally take a 15 minute break. No, seriously, take 15 minutes to stretch your legs, make some coffee, feed your pets, water your plants etc ... and let the Supernode start talking to its peers and collect some data for the next part. Even is your Supernode is not staked yet to receive RTA ts fees, it is still working as a proxy node.
After 15m, let's check out your Supernoode outputs. Two ways to verify if your Supernode is healthy is by checking it's peer list and ID info.
First, lets check if the Supernode list is working right. Be sure to input your Supernode IP in the follwoing command, as per the screenshot. Don't forget the to substitute
Your_Server_IPwith your actual server IP.
Open a new Terminal window! If you close the Terminal window running the Supernode, you will kill the process.
curl --request GET http://Your_Server_IP:18690/debug/supernode_list/1
It looks kind of weird, but that output is a positive sign. You can also use a browser to see the same output using
http://Your_Server_IP:18690/debug/supernode_list/1- You won't be needing this, but is one way to check if your Supernode is working properly.
Next, let's check the Supernode for the info we need to activate it on the network. Issue the following command, but substitute
Your_Server_IPwith your actual server IP. You will see the wallet address you previously configure in
config.inialong with an ID_Key and Signature. We will need these in a bit to stake the Supernode to activate it and start earning rewards.
curl --request GET http://Your_Server_IP:18690/dapi/v2.0/cryptonode/getwalletaddress
You can also use a browser to get this info. Just use the url
It may be easier to visualize and copy/paste for the next part - funding the stake wallet!
- Send the amount you wish to stake to the Supernode stake wallet created earlier, the one in
Once the coins have been unlocked, you can issue the staking command. The syntax is pretty simple.
stake_transfer <SUPERNODE_WALLET_PULIC_ADDRESS> <STAKE_AMOUNT> <LOCK_BLOCKS_COUNT> <SUPERNODE_PUBLIC_ID_KEY> <SUPERNODE_SIGNATURE>
Looks intimidating, but it's pretty simple. Remember a few steps back when you requested the
To remind you, just pop this into your browser. Don't forget to change
Your_Server_IPfor your actual server IP
- So now, go to your wallet and lets complete the
stake_transfercommand, In this case, I will be setting up a Tier 3 node. The ammounts does not need to be exact. Select the number of blocks you want to stake for. 720 blocks is just about 24h. Minimum 50, maximum is 5000 blocks = 1 week
Now, just wait 6 blocks for the transfer to go through and your Supernode will have been activated!
