Unleash the swarm

BitWrk delivers powerful 3D rendering over the internet. If you're a 3D artist using Blender to produce 3D pictures and animations, then BitWrk might be the right tool for you.

By dispatching your work to a swarm of computers on the Internet, BitWrk reduces your rendering times significantly.

Be the swarm

BitWrk allows you to switch sides and be a part of the swarm.

By sharing your hardware, you will be able to make money with BitWrk. This is what makes BitWrk unique.

Like in a stock exchange, you decice what price to sell for.

Pay and get paid in Bitcoin

Employing the famous Internet currency makes BitWrk a new kind of cloud computing, firmly in the hands of the community.

BitWrk depends on its community, and you're invited to be a part of it. Try buying some Blender rendering for an amount as small as 1 mBTC.

Blender 2.76 512M (mBTC)

This chart displays activity in the last 24 hours. It works like a stock exchange. If demand for Blender rendering is low, prices fall. If demand is high, prices may rise. If you're seeing nothing, then there hasn't been any activity during the last 24 hours, which probably means that you have exclusive access to the swarm's rendering power.


BitWrk 0.5.1 "Moon" released Augsburg, Germany, Nov 01, 2015

BitWrk Lightning Talk on 31C3 Hamburg, Germany, Dec 30, 2014

Jonas Eschenburg, developer of BitWrk, held a Lightning talk on BitWrk at the 31st annual Chaos Communication Congress (31C3). In his 5 minute talk, he explained the concepts behind BitWrk and gave an outlook on upcoming events.

Blender rendering a scene using the bitwrk-blender add-on. The flat blocks in the image are work units that are currently being dispatched to the BitWrk service.

BitWrk describes itself as a marketplace for computing power. If that sounds abstract, relax!

In fact, BitWrk is currently covering only one use case: Being a distributed rendering service for Blender, the free 3D rendering software.

BitWrk includes bitwrk-blender, an add-on enabling Blender to dispatch rendering jobs to the BitWrk service.


BitWrk is unique in that it allows you to have your computer accept work from others. This feature is what makes BitWrk an open marketplace. You decide what price your computer works for. On successful completion of a task, your account is credited with that amount. In this screenshot, a worker is waiting for Blender rendering tasks which it sells for 100 µBTC each.


BitWrk uses Bitcoin, a novel payment method. Bitcoin enables you to send money, via your computer or cell phone, to anybody else on the Internet.

In order to buy computing power on BitWrk, you will need to either earn Bitcoin by selling computing power on BitWrk, or purchase some Bitcoin beforehand. Luckily, there are exchanges where you can buy Bitcoin for Dollars, Euros etc.

If you haven't used Bitcoin before, start here: This screenshot shows the Bitcoin depositing process. Sending Bitcoin to the right address from your cell phone is easy thanks to QR-codes.


Frequently Asked Questions

Will BitWrk accelerate my computer?
No. BitWrk will accelerate very specific software, and that software has been converted to work with BitWrk. At the moment, that is only Blender 3D. Not all kinds of software are equally well-suited to be adapted for BitWrk.
Will my device/computer run BitWrk?
The BitWrk client software runs on Windows, Mac OS X and Linux. The front-end is web-based and can be displayed on any mobile device, too.
Where can I register a BitWrk account?
You don't have to. When you run the client software for the first time, it creates an account for you. It will keep a key file (privatekey.wif) to identify itself to the BitWrk service. Your account will be named something like 1MwvTNehPz7U5XYn3h1G7LVPANv3GFq6JR. This does not only look like a Bitcoin address, it is one. BitWrk's algorithms are based on Bitcoin technology.
Does BitWrk cost money?
The BitWrk client software is free (in fact, both client and server are Open Source). For buying computing power, you need a very small amount of money per transaction. That is the whole idea behind BitWrk. The service itself will deduct a small fee (currently 3% but subject to change) off the price of each transaction.
Can I use BitWrk for privacy-sensitive projects?
At the moment, no. Any seller may copy the work data you transmit. In a future version, there will be an option to restrict sellers to a trusted group.
How can I transfer Bitcoin into and out of BitWrk?
In the client user interface, switch to the "Accounts" page. For transferring money into BitWrk, you need to request a deposit address first. This usually takes a couple of seconds. Bitcoins transferred to that address will be credited to your account after one hour on average. Withdrawals from BitWrk are planned, but not implemented yet.
If withdrawals from BitWrk aren't implemented yet, how can I get my money back?
First of all, please make sure not to put any large amounts of money on your BitWrk accounts. Keep your deposits small in order to avoid the situation, until withdrawals can be triggered with the Bitcoin client. Until then, you could ask the developer, Jonas Eschenburg, jonas (at), to send the money of an account to the Bitcoin address of the same name.
What's that animation on this page?
Apart from looking pretty, it is actually a simulation of BitWrk's possible, future user behavior rating system.
