- Create the purchase input transaction.
- Purchase the StealthNode.
- Set the certified node address.
1. Do you have what it takes to run a StealthNode?
Operating a StealthNode is a commitment and requires some familiarity with Unix-type system administration. If you don't have that expertise, or don't want to put in a little time to learn, then you may not be a good fit for operating a StealthNode.
The community can offer some assistance, but at the moment it is not the team's priority to make operating a StealthNode "user friendly" in any way, nor will the team entertain requests to make special tools to that end. Validators for high performance blockchains are expected to be technically proficient, and the lack of "user friendly" tools selects for such individuals.
2. Determine the price.
The price of a new StealthNode is always increasing. Prices go up each time someone purchases a StealthNode and each time a block is minted, because the money supply increases. For this reason, it is necessary to determine the approximate price of a new StealthNode before you buy.
The latest price can be found at the StealthMonitor price history tab under the heading "Next StealthNode Price". It is a good idea to add at least 2 XST to this price to ensure that the price does not increase beyond the funds you have allocated.
If you don't have the funds to purchase a StealthNode, stop here.
3. Acquire the XST
XST can be acquired from Bittrex. After you have purchased enough XST for a StealthNode, we recommend taking custody of your coins by sending them to your own wallet.
Since you will be running a StealthNode, you can set up a wallet on your StealthNode server (see below).
4. Choose a hosting service.
The recommended resources needed to run a StealthNode are 2 cores, 4 GB RAM, and 40 GB SSD storage. Keep in mind that these needs may increase if the Stealth blockchain increases in use. A good hosting provider is OVH, with an acceptable VPS option costing only 10.55 USD per month, as of the time of writing.
Please keep in mind that the Stealth client runs behind Tor by default. Some hosting providers block Tor services. You will need to do your research about any hosting provider you consider.
5. Build the Stealth client and bootstrap.
To build and bootstrap the client, please see the instructions for the recommended operating system.
These instructions should fully synchronize your Stealth client in about six hours, depending on the speed of your server.
6. Encrypt and backup your wallet file.
Keeping your wallet secure requires several steps:
Create a strong password and store it securely. Write it down, put
it in a safe, and/or add it to your password keeper program. Don't
lose this password. Let's use
BADPASSWORDas an example (don't use this as your password!).
Encrypt your wallet with the
StealthCoind encryptwallet BADPASSWORD-- this command will shut down the client.
Make a backup copy of your wallet and put it on your local
machine. From your local machine, use the command
scpor similar to copy and transfer
wallet.dat. Let's imagine your server's IP is
scp 10.1.1.101:.StealthCoin/wallet.dat Stealth-Wallet-Backup-01.dat-- This command makes a local copy of
Stealth-Wallet-Backup-01.dat. Make sure you either backup your computer (e.g. with Time Machine on OSX or similar on Windows), or make a specific backup of this file on a USB drive that you store securely. Remember where you put any and all backups.
Restart you client. The client stops with
StealthCoind stopand starts with simply
Unlock your wallet. You will need your wallet fully unlocked to
run a StealthNode. Don't worry, this can be secure if you choose
to use a correctly configured owner key, as discussed below. The
command to unlock your wallet is
StealthCoind walletpassphrase BADPASSWORD 999999999-- This command unlocks your wallet for 999,999,999 seconds (over 31 years).
7. Determine your Owner key.
The following steps are laid out in detail, so seem lengthy. In reality this should only take a few seconds. The only difficult part is transferring the extended key that you copy on your mobile device to your desktop or laptop workstation. A password keeper, like Bitwarden or LastPass shared on both devices might be helpful.
The first step is to obtain your HD extended public key. The extended public key is a way to derive addresses without being able to spend funds. It is not good to reveal your extended public key because it allows others to determine which funds are yours, but they cannot take your funds with it.
Obtaining the Extended Public Key from Ledger
A) Select the "Accounts" pane.
B) Select the Stealth account
C) Edit the account.
D) Show the advanced information.
E) Copy the extended public key.
Obtaining the Extended Public Key from the StealthSend Mobile App
A) Select the account to use.
B) Select the account to use.
C) Copy the extended public key.
Use the Client to Obtain the Owner Key
The extended public key is a way to derive practically unlimited addresses (each address corresponds to a public key).
If you used the StealthSend mobile wallet in the previous step, you will need to transfer your extended public key from your mobile clipboard to your desktop. There are many solutions. The best is probably to put it in a password keeper (like Bitwarden or LastPass) that you use on both devices.
Once copied to your desktop, issue the command
command in the Stealth client. For example:
Here the extended public key is represented as
xpub661My..., truncated for
formatting. This command, if fully typed out would return:
Notice that two pubkeys are given, one
external and one
change. You can use either, but
best hygiene is to use the external pubkey. In this example it
If these pubkeys come from a Ledger device, then any funds or StealthNodes at these addresses are protected by the Ledger hardware. It's the most secure way to own a StealthNode.
Copy the Owner pubkey you choose to a text file.
8. Determine the Manager, Delegate, and Controller keys.
The StealthNode Manager, Delegate, and Controller keys are critical for the operation of a StealthNode. They can be changed, and different people can be assigned to different keys, to divide labor. The function of the various keys are summarized on Medium under the heading "New StealthNode Manager Authority".
To obtain three different keys, run the these commands, saving the pubkey from each.
Command to obtain the Manager key.
Command to obtain the Delegate key.
Command to obtain the Controller key.
By now you should have four different pubkeys, each corresponding to a different address. You should have these pubkeys saved in a text file for when you purchase your StealthNode. It is recommended to label these pubkeys in the text file so you know which is which in Step 10.
9. Create the purchase input transaction.
A StealthNode can be purchased from any address, but, at the moment, only through a full client. There is no StealthNode purchasing or management functionality built into Ledger Live or the StealthSend mobile app.
First, create a purchase address with the command:
Now, send the price of the StealthNode to this new address. You can send from anywhere, like Bittrex, Ledger Live, or the StealthSend mobile app.
It is IMPORTANT to send all of the purchase price as a single transaction. We will call this transaction the "purchase input transaction".
Note the transaction ID (TxID). TxIDs look like this:
Use your purchase input transaction TxID to determine the
vout of the purchase funds. Here I
will issue the command with the above TxID. In this transaction, 2
XST were sent to the address
gettransaction command to
display all of the information about the purchase input transaction.
I will use the above TxID as an example, though it is not a purchase
This transaction exists on mainnet, so you can issue it yourself to study the output.
The following image shows how to identify the
vout of the 2 XST sent to
Of course you will be looking for the vout with your purchase price.
vout of the 2 XST is
0, circumscribed in red.
10. Purchase the StealthNode.
You now are ready to purchase your StealthNode.
The purchase command help is:
If you have assigned a distinct Delegate, you will want to determine
what percent of the block rewards they will earn for their services.
Let's assume 10%, which will be expressed as
Also, it will be good to determine the most updated StealthNode price:
Get this number and add
0.1 to it,
as it is always increasing, though very slowly.
As of writing, the StealthNode price is
13137.896512. This increase ensures
your purchase will not be rejected because you didn't offer enough
for a StealthNode.
Use this new price as the fifth argument to

11. Set the certified node address.
Your StealthNode is highly configurable, allowing for a great deal of operational flexibility, so you can maximize profits and minimize maintenance. One helpful configurable setting is the so-called certified node address. This setting allows your StealthNode to have preferential connections to the rest of the network, creating a network core of highly connected validators. Read more on Medium.
Since StealthNodes are not yet available on mainnet, I will demonstrate with testnet commands.
A) Determine your IP address.
You can determine this from your hosting provider's account administration tools.
I'm running the StealthNode aliased
HolyGrail at IP
184.108.40.206. As of writing, this
setting actually needs correcting.
B) Determine the StealthNode authority keys.
The command to display the keys is
getstakerauthorities, which returns
both addresses and pubkeys.
The Owner, Manager, and Delegate can all change the certified node
address. Typically, however, this setting is managed by the Delegate
because the Delegate key (and hence the Delegate's server) signs the
blocks. For the HolyGrail StealthNode, the address is
C) Send the fees for updating the certified node address.
It only costs 0.01 XST to make changes to StealthNodes. The command
for sending is
This command returned the TxID
D) Determine the
vout for the fee
You will find the
vout for the 0.01
XST you sent to the Delegate address. See Step 9 above for how to
vout. For example, I
issued the command:
vout of the 0.01 XST for this
E) Issue the
Now we have everything we need to update the certified node address.
This change is achieved with the command
setstakermeta. The help for this

not a public key, but the key of a
key-value pair, in this case
value in this key-value pair is the IP address
220.127.116.11. Putting it all
together the command to update the certified node address for the
HolyGrail StealthNode is:
This command returned the TxID
