You may have many questions regarding helptab.org. About how this works, how the money flows and what's the best use of the features. Some of the main questions are answered on the homepage, for the remaining questions: this is the page.

If you are missing some specific information, please contact as at contact@helptab.org or via Twitter and Facebook. We'll try to add them swiftly :).


What is helptab.org doing?

Today, most computers have more power than needed for everyday tasks. Sure, gaming and professional use require a stronger machine. But when browsing the internet or writing emails, we are only using a fraction of what our computers can do. As a single user it is difficult to get much benefit from this surplus of computing power. So how to put this to good use?

We want to make donating unused computing power simple!

We believe that "the blockchain" is an interesting new technology. This project tries to bring this technology to a caritative use in a crowdsourcing approach. Essentially, it is breaking up big computing task into many smaller ones, organizing the who does what and what organisation gets what part of the rewards.

Unlike operating your own installation of mining software, using helptab.org requires zero installation and can be started with just two mouse clicks.

We organize users computing capacity and forward the rewards to help organisation.

Every donation is small but at the same times makes an impact.

Mining on your own with day-to-day equipment often yields only a few cents profits per day. But we keep track of every small donation you make - as small as it may be. This prevents your drop of water from evaporating on the hot plate. We catch and collect these drops to give them to single projects according to the voice of our users - you.

Simply spoken: the longer you keep the tab open for a specific project the more a single project will recieve at the end of a payout period. The same applies for the number of users. Many user who keep a tab open for a projcet will donate their computing power exclusively to this organisation.

All you have to do is keep a project page open in the background. Press play. Nothing else.

What is my computer doing?

Long story short: your computer is participating in validating transactions on the Monero blockchain. Which is essentially getting a few input numbers, calculating a value and sending the result back. This is also known as mining and helps to make the Monero blockchain safer.

When using helptab.org you are running a small piece of software in your browser. While running, we will send the mentioned tasks to your computer. Once completed, your computer will send these results back and recieve a new tasks. This is a process that is automated.

Is this safe for me?

Yes, this is safe. Here is what happens from a little technical perspective.

When you visit a page with the donation widget you load a small javascript file that contains the mathematical instructions your computer is asked to compute (what is a hash function?). Javascript can be used for many things (what is javascript?). This can be a sliding menu, an animation or calculator. And like in our case, hashing numbers into other numbers (simply spoken: a calculator). This javascript will be executed within your browser and can not access anything else on your computer. When you press play, your browser opens a so called web socket (what is a websocket?). There is nothing fancy happening in that moment.

Contrary to a regular web request, a websocket allows for a permanent connection. This helps to reduce the time needed for requests and improves efficiency of the whole process (and saves some ressources). This websocket will be used to exchange the calculation tasks and their results. That's essentially all it does.

The donation process itself is achieved with the help of coinhive.com (visit website). This is why you will see connections to their server. They track nothing about you. The only thing they store (for a short time) is the IP address to allow the websocket connection to happen and prevent abuse. They don't know anything about you. We do not give your personal information to anyone.

We do not want access to your addressbook, webcam or credit card. Basically, we just need a mail address to contact you, when you create a user account (and to notify you of any wins). Never will someone from helptab.org ask you for personal information or your personal private blockchain keys.

You can still use most of the website anonymously without an account to try it out.

How do my donations end up where they are supposed to be?

When you are using the donation widget on a project page, you are calculating so called hashes for the Monero blockchain project. We organize this with the help of CoinHive (who provide the mining software) and the helptab.org platform. Coinhive pays us whenever enough hashes have been calculated by all users combined. This depends on how many people are using helptab.org. When many people use it, we get paid more frequently and a higher amount. Especially in the beginning of helptab.org it will rather take weeks than days.

When we get paid, we get paid a certain amount of Monero (short: XMR) as a whole for all projects and users together. The amount mainly depends on two factors: the hashes all users of helptab and the mining reward during that time. The reward can fluctuate and depends on the hasrate of all users of the whole Monero blockchain.

The amount of Monero (XMR) we get is initially paid to our "incomming wallet" of helptab.org. From here on, we send the Monero to dedicated single wallets for each of the help organisation. These extra wallets help to keep stuff seperated and transparent. This also ensures tax authorities don't see your donation as our income but as a donation we just forward. Thus a higher amount of your donations can be forwarded to charity organisations.

To learn how to verify transactions on your own, please see this external guide on verifying Monero transactions.

What do you earn from this?

Our income is an operating fee we deduct from the helptab.org incomming wallet - The vast majority goes to the dedicated wallets for organisations of which nothing is deducted any further (except direct costs of transaction and exchange).

At the beginning, this operating fee will be 30% of all donations. Even when that 30% doesn't cover our expenses, the 70% will still go to the good causes. We will pay for the rest of the expenses ourselves.

When the project covers it's running costs, we will reduce the operating fee deducted from your donations to 15% - so that a whooping 85% of the XMR recieved can be forwarded to your charity organisation of choice. We do not yet know when this will happen, but we'll let you know.

Also keep in mind that the 5% for the "Monthly Giveaway" are already included in our operating share and will not be deducted from the donations.

What equipment and software do I need to support you?

You can use virtually any device that supports a modern browser. Desktops and Laptops work best, mobile phones and tablets sometimes work. It depends a little on the hardware here.

Since donating computing power requires more power than not doing so, mobile device should not be your first choice. To give you an estimate: using helptab.org with standard settings will roughly consume 1% battery charge per Minute on an iPhone 7 (2 Threads, 50% Intensity, yielding 12,5 H/s). With higher settings this can get up to 2% per Minute. Which means after an hours, your battery is flat. Also, with older batteries, consumption could be more. This would also put extra cycles on your battery wear that you might want to avoid. Though the latter is actually only relevant when you use helptab.org a lot with your mobile device - but we want to be transparent and point this out to you.

As such, it makes sense to use something with a power supply, like a regular desktop computer or a laptop. The amount you can donate through your browser varies greatly. There are essentiall three factors that influence your donation.

a) What hardware are you using (the important thing is your CPU, your GPU does not matter at this point). A modern and strong CPU will allow for higher donations.

b) What are your settings? The more threads and intensity you pick - the more you donate.

c) What you are doing on your computer when donating. Doing CPU heavy stuff will leave less computing power to donate.

What are the settings in the donation widget good for?

With the following settings you control how much computing power you donate.This is the donation widget when it is running. It shows your current speed and the total of hashes donated since the page was reloaded.

 src=

There are two factors you can influence:

a) Threads: this is the number of how often the programm is started. A large number isn't always the optimum. On any kind of halfway regular computer a settings between 1-4 will be a good choice. You can try higher numbers, but at some point this will slow down your computer. We suggest the value "2" as a default.

b) Speed: this is the intensity of the donation process running. Selecting a lower value is good when you work intensively on the computer while donating. In this case pick something like 10-30%. If you are just browing the internet, reading mails and doing very little on the computer, you can go as high as 100%. The default value is 50%.

Especially when both settings are set to high numbers, you will feel that your computer is getting laggy. We suggest adjusting your individual settings to a point where you are satisfied witht he donation level and your computers perfomance.

Don't feel bad when you only want to donate a little and choose low settings. This is why we are doing this. Every second by any person will get recorded and forwarded to its purpose.

What does it cost me to support you?

Glad you ask, since we took some efforts to measure all this. Let's take two different computers, one very low power, small and cheap processor, the other a fairly recent workstation with multiple screens. We measured different setups and made the following observations. This should give you a good idea of where your equipment sits. For the calculation we assumed a very expensive rate for electricity of 30 cents (Euro) per Killowatt/hour.

Most likely you live in a place where it is much cheaper. In the USA it would be around 10-12 cents (Euro). Here you can take a third of the price we calculated. It is very cheap to support us.

To put these number into perspective:
here is the power consumption of a few daily tasks. These also heavily depend on the type of oven or dishwasher, but to give you an idea

  • Heating up a frozen Pizza: ~ 1.5 KWh
  • Dishwasher: ~ 0.7 KWh (one run)
  • Small fridge: ~ 0.4 KWh (daily)

So if you have a very big computer, and let it donate at high speed while you are reading mails (for let's say an hour per day), you consume an extra 1.5 KWh per month which equals to one fozen pizza prepared in a regular oven . That same big computer computer would consume 36 KWh when donating 24 hours at very high speeds for a full month. With the current average price for elecricity in the USA, this would be roughly 3 USD per Month. In countries with very high elecricity prices this can be up to 10 Dollars per Month.

But then again, the average user, with an average computer with a few hours per day will be in the area of cents per month.

Do I have to be on the internet

Yes, you need to be connected to the internet during your donation. Your computer will constantly recieve new tiny jobs and will send the results back.

Again, it depends on many factors how much data is consumed. At a hashing rate of about 10H/s it's roughly 1.5 MB per full hour. On a desktop computer with high settings and 100H/s, the consumption will be around 15 MB per hour. And that would already be quite a lot. So we are very easy on your internet. Looking at a few funny cat pictures will cost you about the same.

What can I see on my profile page?

Your profile page (my account) is your single location to adjust your public team name, enabling the automatic start of the donation widget or seeing statistics about your donations. You will get to this page once you log in.

My contributions per project

This is a table and chart that lists all projects you have engaged with by the number of shares you calcuated. These are usually big number that can quickly grow into the millions over time. Thinks of this: When you donate with 10 Hashes per second, you will donate 36,000 Hashes in one hour. If you do this every day for an hour you roughly have one million hashes after one month.

This may sound a little bigger than it is. To put this into perspective: For a million hashes you donated, we will recieve about one dollar-cent (16.05.2018). So for every hash donated we roughly get a millionth of a dollar-cent.

This perspective again makes your contribution look very small. But consider, you are not alone. Small drops swell into an ocean.

My contributions over time

This chart shows how many hashes you have donated during the last 30 days.

Account setting: Always Mining

When you activate this checkbox and save your settings, you allow us to start the donation widget automatically when you look at a charity project page. This is generally a good choice, so you do not forget to click "start mining". We didn't want this active as default, so you have better control over the donation process.

Account setting: Public name

The "Public name" is like a team name. You are free to choose whatever is shown here. If you leave this empty, your stats will be aggregated with the statistics of all other users with an empty field. You will be shown as part of "anonymous". Your personal user statistics will not be affected, no matter what name you put here.

As a matter of privacy we didn't want to use your personal information. So we came up with a little twist:

Think of this, you say something, others can chime in with their donations. Others can have the same name, nobody owns a certain name. When multiple users have the same name, you statistics will be joined for the leaderboards. This way you can raise awareness for a thing or your group by joining forces. It doesn't affect anything, it's just a little fun field to play with. 

Examples of good public names could be something like "Boyscouts Ohio", "Florida Students", "Friends of Benny" or "I like trains".
