Notes on Gridcoin Mining Using Google Cloud Computing

Gridcoin (GRC) is an altcoin that can be mined through contribution to scientific research (PoR - Proof of Research), more specifically, by doing BOINC (Berkley Open Infrastructure for Network Computing) hosted computing work. It makes cryptocurrency mining a more meaningful thing and is very suitable for mining use a VPS such as Google cloud. Different from other cryptocoin mining, you don't need to worry about the violation of TOS as you're running the BOINC computing software instead a miner on the VPS.

The following steps will guide you to mine Gridcoin on Google cloud, which is based on but much simpler than the official tutorial -

1. First follow the official guide to setup both BIONC and Gridcoin wallet on your own (local) computer. Make sure you use BAM! account manager in the tutorial.

2. Sign up for the Google cloud free trial:

3. Follow the official Steps 2-6 to create your google cloud instance.

4. The official tutorial doesn't use an account manage, to simplify the process, I strongly suggest you to use BAM!, so you can skip the official Steps 7 and 8.

5. For official Step 9 - in the SSH terminal enter the following commands, each "$" indicates a single line (if you're using BAM!):
$ sudo apt-get update
$ sudo apt-get install boinc
for each project that you want to run, enter:
$ boinccmd --project_attach PROJECT_URL AUTH_KEY
replacing PROJECT_URL and AUTH_KEY with the values that you gathered in step#8

$ boinccmd --join_acct_mgr BAM_ID BAM_Pass
(replacing BAM_ID and BAM_Pass with your BAM! ID and password.)
$ boinccmd --set_run_mode always
$ boinccmd --set_network_mode always
The following commands are useful for monitoring the state of BOINC:
$ boinccmd --get_simple_gui_info
$ boinccmd --get_tasks
$ boinccmd --get_file_transfers
6. Follow the official Steps 10~14.

Other Notes:

1. If you want to change the BIONC projects for Google cloud to run, just manage the projects for Google cloud instance using BAM!, and re-input the command to update the BIONC projects and syncs with BAM!:
$ boinccmd --join_acct_mgr BAM_ID BAM_Pass
2. On your personal PC, where your Gridcoin wallet is installed, you should add all the BIONC projects you joined, although you can suspend them locally and only run them on Google cloud for BIONC credits.

How to Mine Bytecoin, Monero and Fantomcoin Using Google Cloud Computing Free Trial

Google cloud offers everyone $300 credit for free to spend over the first 60 days on signing up. You'll need a valid credit card for registration but won't be billed during the trail. The following steps will guide you to mine Bytecoin, Monero and Fantomcoin on Google cloud:

1. First register for a MinerGate account using your email.

2. Sign up for the Google cloud free trial:

3. In Google cloud console -, create a new project, and give it a name. You may check the tutorial (a video tutorial included) before you go on.

4. Go to your project dashboard - something like "", add a VM instance by click "NEW INSTANCE" button. Change the "Machine type" to "High CPU machines (n1-highcpu-2, 2 vCPUs, 1.8 GB Memory)", and change "Boot disk" to "Ubuntu 14.04 LTS (amd64 trusty image built on 2015-09-09)". For the "Firewall", tick both "Allow HTTP traffic" and "Allow HTTPS traffic". Then click "Create".

5. Find you created instance, click "ssh", "Open in Browser Window".

6. Now, in the console, input (you can ctrl+c and then ctrl+v into the web terminal) the following three command lines (one line + enter key, each time):
sudo dpkg -i deb-cli
nohup minergate-cli -user youremail -bcn 2 -fcn+xmr 2
where you should replace "youremail" with your MinerGate account email.

7. Now you can close the ssh browser window. Check your instance's CPU usage, which should be about 100%.

8. You can repeat the above steps to get more instances (You can also create a "Snapshots" of your VM instance just created and duplicated it to get more instances).

9. Now you can just let your project running for the whole trial period. Don't need to worry about your credit card being charged as according to google's FAQ, your projects will be paused automatically when your trial credits run out and you won't be charged unless you upgrade your trial account to paid account.

Warning: This tutorial is for demonstration purpose only. Use google cloud for cryptocurrency mining only may be a violation of its TOS and may result in your google cloud account being suspended (Although this has not been confirmed as their terms of service is vague about this). Try at your own risk! If you're worrying about that, you can safely delete your newly created computing project now.


Why Bytecoin and Monero?
As is known to all, nowadays it is not profitable anymore to CPU mine most cryptocurrencies, such as Bitcoin or Litcoin. This page ( listed some altcoins that are still suitable for CPU mining, in which Bytecoin and Monero are the most popular two according to the cryptocurrency rank:

Eobot - Cryptocurrency Mining Made Easy

Eobot is a cryptocurrency mining pool and it offers cloud mining products such as Cloud SHA-256 2.0/3.0 GHS. Currently, it supports to mine Bitcoin, Litecoin, BlackCoin, Namecoin, Dogecoin, Dash, Reddcoin, BitShares, CureCoin (Cloud Folding), StorjcoinX, Monero, Counterparty, Stellar, Bytecoin, Peercoin, NXT, MaidSafeCoin, EthereumDAO, Lisk, FactomVoxels,  Gridcoin (Cloud SETI) and Gold. You can mine on your own hardware using their miner software on Windows, or join their pool (SHA-256, Scrypt, X-11) using some other popular miner such as cgminer, cpu miner on Windows as well as Mac/Linux.To speed up your mining, you can buy their cloud (using your cryptocurrency deposit, PayPal Credit Card or US bank transfer), the 5 year rental contract for Cloud SHA-256 3.0 GHS is now about $0.90 per quantity (subject to Bitcoin price change, with total supply 100 THS). However, as they suggested, "Cloud mining should be considered as a fun, recreational activity and not a source of income or investment", it is not wise to invest too much.

You'll receive one free Dogecoin when you log in and can get about 2000 Bitcoin satoshi through their faucet, everyday. You can deposit, exchange and withdraw your cryptocurrency and the cloud rental in your eobot account; and the exchange fee is 5%, withdraw minimums are 0.001 BTC, 0.2 ETH/LTC/DASH, 1.0 DAO/CURE/PPC, 10 XRP/XMR/FCT/LSK/BLK, 100 DOGE/VOX/MAID/BCN/GRC, 1000 BTS/XEM, 10000 RDD, 1g GOLD.

Tips (How to mine without investment/claim free mining power from faucet): After registration, go to your account, change "Mining:" (top left corner) to "GHS 4.0" "GHS 3.0" or "GHS 2.0", then go to Menu Products -> Faucet (top right corner), you can claim free (cloud mining power) GHS contract everyday. Now you have some cloud GHS, you can change "Mining:" to what you want to mine. It's suggested to mine DOGE Bytecoin (BCN) as a beginner because it has the lowest withdraw threshold. The faucet will give you what you're mining when you claim. It's not suggested to claim some cryptocurrency and then exchange it to cloud mining power because there will be a >=5% exchange fee. So it is better to claim GHS contract directly (always change "Mining:" to GHS before faucet claim, after your claim, change "Mining" back what you want to mine).
To mine multiple coins at the same time, change "Mining:" to "Diversify", so you can select more than one coin you want to mine.

P.S. you can also use Eobot as an online multi-cryptocurrency wallet (with no withdraw fee and no fee for deposits but with minimum deposit requirements: 0.0001 BTC, 0.001 ETH/LTC/DASH, 0.01 DAO/CURE/BLK, 0.1 XMR, 1 DOGE/XRP/FCT/PPC/MAID/GRC, 10 RDD, 5 BCN, 100 XEM), or an instant cryptocurrency exchange service because you can deposit and exchange between any two of the cryptocurrencies it supports at any amount (however, the exchange fee is a little high from 5%).

How to Start Earning Some Free Bitcoins in 10 Minutes

Firstly, you need to have a bitcoin wallet. If you don't have one, you can register an account for free at Then you'll get a bitcoin address (check your blockchain wallet dashboard, receive money, Addresses, Your receiving bitcoin addresses, the "Active" tab), which looks like some long random string. For example, my is "1D8kTXYk2srgGuTrCBP3wu64288GwqKCoS".

Now you are ready to go to some faucet sites and earn free bitcoins. Faucet sites are supported by online advertisements and get their traffic by tipping bitcoins (or other cryptocurrencies) to visitors.There are many faucet sites, usually pay you 100~1000 satoshi (smallest fraction of a Bitcoin that can currently be sent = 0.00000001 BTC) each time you visit. As a beginner, I suggest to try, which is user friendly and proved to pay. No register needed for (you can secure your epay account by an email and password later), just go to the URL like,
with the bitcoin address "1D8kTXYk2srgGuTrCBP3wu64288GwqKCoS" in it replaced by yours. It shows you a list of faucet sites - just click the button "start browing faucets", you are visiting the faucet sites using epay's rotator. And inside the faucet site page frame, all you need is to find the buttons like "Spin"/"Next"/"Claim" hidden in the ads and solve some captchas (to prove you're a human). After that, you'll get your free bitcoins paid into your epay account.

Once you get paid, you can click "visit next site" (on the right upper corner) to go on your earning. You can withdraw the bitcoins in your epay account to once you reach 0.00013000 BTC (this is not hard since if you play all faucet provided by epay at the time, you can earn 1,543,586 satoshi daily).

KOReader - Turn Your Android Phone and Tablet into a Kindle-like E-reader

KOReader is an open source document viewer, originally created for Kindle e-ink readers. It currently runs on Kindle 5 (Touch), Kindle Paperwhite, Kobo and Android (2.3+) devices.

The most important feature of this app as a pdf reader that many other apps (including Adobe's own PDF Reader for Android) don't have, is text reflow for scanned documents and scientific documents with lots of mathematical formulas, thanks to its built-in K2pdfopt support. What's more, since it is originally designed for Kindle e-ink reader, the app has a very similar look and feel as the Kindle e-ink user interface, which is very clean and elegant. However, first time users may not be used to this Kindle-like interface and touch. For example, at first I thought I need to scroll down from the top of the screen to open reader's setting menus, which is of course a conflict with the default gesture input for opening the Android message center. Then I realized that a single tap at the top center of the screen is the right way to open the setting (while the typical back and menu buttons of an Android phone actually do nothing with the app). But if you have some experience with the Kindle e-reader, it is very natural and easy for you to get started with the app.

This free app can be download at:
(Including ".apk" version for Android phones and tablets, as well as the Kindle and Kobo e-ink reader version.)
