Introduction: Linda is a hybrid masternode coin that promises great ROI, and supports PoW (Proof of Work) and PoS (Proof of Stake). Since many of us can't afford a full Linda masternode yet, the next best thing to do is earn some interest on your coins by staking them. This guide will cover how to purchase your VPS, setup your VPS, setup your wallet and eventually how to stake your Linda coins with the Lindad Ubuntu command line daemon. 2. Purchasing a VPS from Vultr: The easiest and best way to ensure maximum return for your staking is to setup your wallet on a VPS which will always be on. Below are the steps for purchasing a VPS from Vultr which will run you $5/month currently. a. Visit the following URL: (Using my reference code will get you $10.00 in free credit to use after your first month) b. After you have clicked the link, create an account or click deploy now to get started. c. Step 1: The first screen you see should show you a list of locations for your new server. Choose the best location for your location.

2 d. Step 2: Further down the screen you will need to select your server type. You will want to select Ubuntu version 16.x as seen below. e. Step 3: Choosing your server size is easy. I highly recommend the $5.00 per month option as it will be enough memory and space for the job. Do not select the $2.50 a month option as compiling with only 512MB of RAM will be difficult.

3 f. Steps 4-7: You can keep these all set to default unless you see a feature that you require. g. Step 8: Enter the hostname and server label for your new server. You can create an actual hostname and point your hostname to your IP if you wish. Otherwise, you can just put a simple made up name here and just connect via IP in the future to your new server. h. Last step is to click on the Deploy Now button and watch your server get prepared in minutes. You will see a Installing text next to the server in the list while the process completes. Once the server is completed, it will show Running as the status. At that point click Manage and proceed to the next step. 3. Setting up your VPS After your VPS is ready, follow the steps below to prepare your VPS for use. a. Connect to your VPS: After you have clicked on the Manage link in the previous step. You should see a screen similar to the one below with your server details.

4 b. There are a few ways to access your server at this point. The first and highly recommended way is via Putty for Windows. I recommend this because it will allow you to copy and paste commands from this guide. The second way is by clicking on the View Console link at the top of the page that looks like a computer screen with symbols >_ at the top of the page. To connect via the console, simply click that icon at the top of the page. For a guide on connecting with Putty, visit the following URL: Follow the guide to connect to your server via the IP address which will be shown on the Manage page as seen above. c. Once you are connected, we can get started. You will want to login using username of "root" without the quotes and then your password which will also be displayed on the "Manage" screen above. Click on the eye icon to view the password or the paper icon to copy it. Please note that you cannot paste into the console view, you can only paste if you are using putty. d. You should now be logged in at this point and you will see a prompt similar to the one below: root@servername:~# e. Install dependencies: Run the following commands one at a time in order to satisfy the requirements for setting up the Linda wallet. Hit the y key followed by clicking ENTER if you receive a prompt to confirm download.

5 apt-get install build-essential libtool automake autotools-dev apt-get install autoconf pkg-config libssl-dev libgmp3-dev libevent-dev bsdmainutils apt-get install libboost-all-dev unzip add-apt-repository ppa:bitcoin/bitcoin apt-get update apt-get install libdb4.8-dev libdb4.8++-dev f. Create a Swapfile: Since we will be compiling the Lindad command line daemon, we will need a swapfile, or the compile process will run out of memory. This example will create a 2G sized swapfile which is optimal for a 1G VPS. This is how we create one: fallocate -l 2G /swapfile chmod 600 /swapfile mkswap /swapfile swapon /swapfile Now let's make this permanent so that if your VPS restarts, the swap will turn on automatically: echo '/swapfile none swap sw 0 0' sudo tee -a /etc/fstab g. Let's Setup Your Firewall: This is an important step that should be taken seriously. Basically we want to close all ports and only allow access via SSH / Putty if you need it and close everything else. We will also open a port for the Linda daemon to communicate with the nodes. Type the following commands: ufw allow ssh ufw allow 33820/tcp ufw enable You have now setup and enabled your firewall. You only need to add ssh above if you plan on connecting via putty or via ssh. If not, you can type the following to disable it again.

6 ufw deny ssh ufw enable 4. Setting up the Linda wallet Let's Setup your Linda wallet. a. Now let s download and compile the Linda wallet. Please note that the make command will take a little bit of time. Go make yourself a snack while you wait. cd ~/ git clone cd Linda/src make -f makefile.unix cp Lindad /usr/local/bin cd../.. rm -r Linda b. Now let s start the Lindad demon in order to create the files we need. Once you type the first command below, wait about 30 seconds and type the next command to stop the demon after the directories are created. Lindad -daemon (Hit ENTER) (Wait 30 Seconds) Lindad stop c. Get the Bootstrap Files: Use the commands below to get the latest Bootstrap files which will drastically decrease the syncing process. Once we are done, we will restart the Lindad deamon. cd ~/.Linda/ wget

7 unzip -o bootstrap_latest.zip cd.. Lindad -daemon (Hit ENTER) d. Encrypt Your Wallet: Let's take a moment and encrypt your wallet with the following command: Lindad encryptwallet "your password" ***DO NOT FORGET THIS PASSWORD*** Now restart the Linda daemon: Lindad -daemon (Hit ENTER) e. Get Started: Although you have the latest bootstrap, you may be a little behind and the wallet will need to sync a while longer. Because we used the bootstrap though it should now be a matter of an hour or less instead of days. Below are some commands to track the progress. Lindad getinfo Will display something like: root@servername:~# Lindad getinfo { "version" : "v g", "protocolversion" : 60032, "walletversion" : 60000, "balance" : , "newmint" : , "stake" : , "blocks" : , "timeoffset" : -1, "moneysupply" : , "connections" : 60, "proxy" : "",

8 } "ip" : " ", "difficulty" : { "proof-of-work" : , "proof-of-stake" : }, "testnet" : false, "keypoololdest" : , "keypoolsize" : 100, "paytxfee" : , "mininput" : , "unlocked_until" : 0, "errors" : "" Look for the "blocks" line and you should note that every time you repeat the command the block will rise more and more. When it stops for more than 30 seconds or more, that will mean you are now in sync. Feel free to continue with the next steps though while you wait and proceed with the setup. f. Create Your Wallet Address: While your wallet is syncing, let's create a new account address for address 0, and make a note of it: Lindad getaccountaddress 0 Now let's save your address to a text file in case you need it down the line for easy access. Lindad getaccountaddress 0 > linda_wallet_address.txt To view your address at any time you can type the following: Lindad getaccountaddress 0 g. Send Your Coins: Now that we have the wallet setup and your address has been established, let's send coins to it. Copy the address from te output on the above commands and send from your exchange or wallet of choice. You can check to make sure your transaction made it to your new wallet by running: Lindad listtransactions Once your funds arrive, we can now get ready to stake your coins in the next step.

9 It is important to remember that in order for your coins to stake, they will need to mature in your wallet for 24 hours after they have arrived. h. Let's get Staking: Follow the steps below to unencrypt your wallet for staking and get the process started. Lindad walletpassphrase "the password you set above" Now, you can check on your staking status: Lindad getstakinginfo And the output should be something similar to this: Lindad getstakinginfo { "enabled" : true, "staking" : false, "errors" : "", "currentblocksize" : 0, "currentblocktx" : 0, "pooledtx" : 1, "difficulty" : , "search-interval" : 0, "weight" : 0, "netstakeweight" : , "expectedtime" : 0 } If you see "enabled" : true, then your wallet is staking. You will need to wait 24 hours before you see "staking" : true. You can estimate your next payout time by looking at "expectedtime", but keep in mind it is just an estimate, and is not a guaranteed time. And there you have it, you're successfully staking Linda on Ubuntu 16 Linux. 5. Backup your Linda wallet It is important that you backup your wallet somehow. Use any SFTP or SCP program to connect to your VPS, and backup your wallet.dat file to your local desktop or laptop. That file is located here: ~/.Linda/wallet.dat

10 Additionally, you and also use Vultr to take a snapshot of your newly completed VPS. a. From the "Manage" screen. Click on the "Snapshops" tab towards the top. b. Next, under "Take Snapshot" enter a Label for your snapshot like "Linda Wallet Server". c. Click "Take Snapshot" d. You can use that in case something happens to your server to restore a full backup of your server to a new instance. 6. You are done!
