WEBDOLLAR — Currency of the Internet. Easy to mine, gereat project, real potential, maybe the first blockchain product that will reach mass adoption. As I write this tutorial almost 6.000.000.000 WEBD are mined from a total supply of 42.000.000.000. Difficulty is pretty high so mining in browser is not rewarding. Here’s how to achieve at least 100k hash power per second for free.

Step1 — Create a Google Cloud Account

Make sure you have a Google Account. Open www.google.com and search “Google cloud”. Click the “Try now” link.

Login with your Google Account, choose your country and accept the terms and conditions.

In the next step complete your personal information, including credit/debit card for billing.

IMPORTANT: You will not be charged unless you spend all the $300 received for trial. So no worries here, I will explain how to stop mining when you reach the $300 limit.

Click “Agree and continue”

Step 2 — Create your Virtual Machine Instances

After your account is set up, click on “Compute Engine” section and you can star creating your VM instances.

.. and now, this:

Before you start clicking around this step, you should know that:

  • you cannot have more than 64 cores in trial (at least I couldn’t)
  • each Region has a maximum vCores limitation (most o them have 24 cores), so make sure to create VMs according to the maximum allowed. No worries, Google will let you know if you can deploy the vm or not. You will figure it out
  • In the “Machine type” dropdown, in order to have more cores available you need to create a billing profile. Just click the link and you can then choose 24 and 64 vCores machines to deploy
  • In the boot disk section click “change” and choose Ubuntu 18.04 LTS (not minimal, just LTS)
  • In the right side o this panel you have the cost per hour information. WRITE THAT DOWN because after you created all your machines you have to sum all costs per hour and divide the $300 to the total. This is the total number of hours you can keep the VMs on. Ater that, you will be charged. Make sure you calculate this numbers corectly. For example: If you have a total of $3 per hour you will have 100 hours of trial (300 /3). That is 4 days. Remember this so you can switch them off and not get charged.

Check the Firewall check-boxes and hit “create”

Repeat the step and create your VM instances.

If creating your instances you reached the vCPU limit or you can’t build the VM you will get something like this:

Put the mouse over the red circle and learn what went wrong.

Try to change the Region and CPU numbers until you make it. Remember the overall limitation so you know when to stop.

After you reached the limit, you should have something like the picture above.

STEP 3 — Install the WebDollar miner

For each instance in your list, click “SSH”. A new window will open that will take you to the Ubuntu Console. Before you start installing the miner make sure you have two things available to copy — paste:

  1. A pool link. My favorite: WMP Pool: https://mine.webdollarminingpool.com/pool/1/WMP/0.02/bdda9527a040d9063e22e1dccc4d860b84227ff73232f5c418054112114a6ea4/https:$$pool.webdollarminingpool.com:443
  2. Your secured WEBD wallet. Here’s how to get one:
  • go to www.webdollar.io (or just visit the POOL LINK ABOVE)
  • in the bottom — right corner click the “Wallet” tab to show your addresses
  • click the lock icon to encrypt the wallet and set a 12 words password. You can generate a random one right there, MAKE SURE YOU SAVE THAT AND KEEP IT SAFE.
  • click the down arrow to download the address.
  • open the downloaded file with notepad and let it oppen. ALSO SAVE THIS FILE AND KEEP IT SAFE. THIS IS YOUR ADDRESS worth millions.

If you see this, you are on the right track:

Now, to install the miner, type the following in the terminal (for each terminal) and hit “ENTER”:

git clone https://github.com/WebDollar/Node-WebDollar.git Node-WebDollar1

Affter the clone is ready, type:

cd Node-WebDollar1

Type “enter” and then type:

bash install-miner.sh

Hit “ENTER” and now wait.

Ater the install is over (no more scrolling in terminal) you will be adviced (in red color) to run source ~/.profile . Type it and hit “ENTER”.

One more thing: BUILD THE ARGON2 CPP MINER for best miner performance. Type:

bash build-argon2.sh

..and hit “ENTER”. You will be asked what type of miner you wish to optimize. You choose 1 (CPU), then “ENTER”. You then type y and “ENTER”. You are then asked how many cores you want to use for mining. You will choose the maximum. On this line the terminal will inform you on how many cores you have available. So, for example, if it says you have 16 you type 16 and hit “ENTER”

Now you have installed the minner.

STEP 4 — Start MINING

Remember the pool link and your notepad WEBD wallet? now it’s time to use them. First, the address:

  • type cat > x.webd and type “ENTER”
  • paste the whole text in the notepad file you have oppened and hit “ENTER” (yes, the long text starting with { and ending in }
  • hit CTRL+D

You now have your secured minning address on your Virtual Machine.

Type npm run commands and hit “ENTER”. The commands will appear on the screen (in blue, from 1 to 11–1 or 20.. whatever)

Now, import your address:

Type 4 and hit “ENTER”

You will be asked for your address path. Type x.webd and hit “ENTER”.

Now, you must set your address as the minning address. Type 7 and hit “ENTER”. Now, type 1 and hit “ENTER”.

Hit CTRL+C and end commands. Now, to make sure your VM instances will mine regardless of you having a computer connected to the terminals, you must run a screen on the servers.

Type screen and hit “ENTER”. Press “SPACE” until you can run commands again.

Type npm run commands and hit “ENTER”.

Type 10 and hit “ENTER”.

Now, you are asked to type in the POOL LINK. Just paste the pool link and hit “ENTER”. I mine in WMP pool: https://mine.webdollarminingpool.com/pool/1/WMP/0.02/bdda9527a040d9063e22e1dccc4d860b84227ff73232f5c418054112114a6ea4/https:$$pool.webdollarminingpool.com:443

And you are now minning. You do this on all VM instances and you must have about 100k hash power or even more, depending on how many VMs you are allowed to create.

Happy onest mining! ;)
