I can't believe I'm just learning about taking bitcoins to space. I'm an aerospace engineering student and will definitely be following this. Is the best place to learn how I can contribute here and the Google group? It's precisely this kind of thing that I want to do as an engineer.
Expect an extensive project update in the next day or two.
Thanks for keeping us updated.
For the people that think that this is fake please post some photos related to this satelites or the company that is going to launch them.
Very cool! Congratulations on this project.
I will donate after the update

The news is out! http://www.prlog.org/12313639-bitcoins-in-space-one-step-closer.html
As you can see from watching the donation address on blockchain.info, we have already made the first $16k contract payment (as well as a 1 BTC payment to Corgan Labs).

Exciting new news coming mid-April.
Ceremonial moon landing anyone? Eh? Eh?
Good luck with this project, Bitcoin wil survive even if all humans on Earth are gone.
I've sent small donation, hope it will help. I've never thought that I'll participate in actual space program

Enjoy small donation from zoidberg.eu. Wanted to buy new shoes, but this project is more important.

What you are intending is not in goodwill of the amateur radio service.
There is a flood of cubesat´s the last years, most of them using frequencys of the amateur radio service, while not providing good services to radio amateurs. This is due that the hardware available is usable on the amateur radio service frequencys.
But none of those is providing something what is of use for the amateur radio service, like transponders, pictures from orbit etc. And also even most of them do not provide all data to decode by amateur radio operators. The amateur radio community should be included in every satellite project, which is not the case with most of the cubesats, while using our frequencys.

I do not think of that a satellite like "BitSat" is of use.
But if done on other frequencys ok.

Is this project working with - https://www.outernet.is/ - who aim to broadcast the blockchain from space.
i had a project for providing cheap internet access to poor countries using this type of sat ....but costs for geostationnary sat is too high to make is possible
Correct, geostationary tends to be considerably more expensive.
Based on your stated plans, I'm wondering what is the goal of this project exactly? One satellite doesn't cover the whole world very well. Is it just local coverage? US only? Not related to BitPay, though?
Let's take a guess...
This sounds high...
http://www.satmagazine.com/story.php?number=602922274
This is an older article, but even considering a 2.5x increase in the price of oil and quite a bit of inflation, launch costs for a 3 cube satellite really shouldn't be more than $0.5 mil today.
And if we look here, for instance, we see that a 3u cubesat launched to LEO costs $325k. But, a geosynchronous orbit costs $1 million.
So... what's the plan? Where is this thing going to broadcast?
Let's take a guess...
Rough cost estimates of a single cubesat:
- Launch: $1m
This sounds high...

Through companies like Eurokot and Kosmotras, the launch costs are currently about US$40,000 per single cube.

hi
the geo one costs is only the sat or launch included?
ok it s only the launch cost
how about the sat itself?

Awesome Project Jeff !

Oh, I'm not talking about cubesats in geostationary orbit--I'm referring to transponder leases on Intelsat and SES satellites. But you're right, orbital slots are tightly controlled. I believe all nations have a slot, which is why you see some satellites flying under the flag of Isle of Man or Bermuda.
You can put deployable solar panels on a 1U. Check out the Ecuadoran Pegasus: http://en.wikipedia.org/wiki/NEE-01_Pegaso
There are many things to keep in mind regarding risk and orbital debris mitigation, but it's a pretty standard punch list. As long as the satellites naturally de-orbits in less than 25 years, all is good. A cubesat at less than 600km only has a 5-7 year mission duration before orbital degradation causes it to burn up on re-entry.
I was not aware with LAICE--thanks for the tip. But it's a 6U, which is considerably more expensive to launch. Still a very interesting project.

Aye! that is true
Another thing about Cubesats in geostationary orbit is power requirements on the satellite itself . At LEO say at 350-400 km on a 1U cubesat, you will get about 2W max power from body mounted solar panels. Now I am not sure how that will scale up when you go in higher orbit, but for transmission from that altitude power requirements would be significantly higher. Someone needs to look into it. How big of a satellite you are planning on launching anyway? it might be hard to fit everything in 1U. Deployable solar panels may be the answer here. But that brings you to sizes larger than 1 U.
Moreover isn't there strict guidelines you have to follow at geostationary spots? cubesats have strict regulation to keep debris hazards in check even when you launch in LEO. Explosive bolts, for example is forbidden. I would imagine there would be stricter restrictions for geostationary orbit.
Edit: @ Syed, It seems you are an UIUC alum (from the outernet.is website). You know about the LAICE project?

Yes, you can definitely make this a university or ELANA, but then you will have no control over the timeframe. One of the PhoneSats that Ames launched was sitting on a shelf for 18 months, literally.
I don't know much about Jeff's plans, but he and I are working on similar projects. Geostationary orbit is going to be way too far away--free space loss will be huge. Even at the higher transmit powers allowed under Part 97/amateur radio satellite rules, a signal will be tough to pickup by a consumer-grade ground station/dish.
The way to get immediate (as in next month) global coverage of transaction broadcasts is by using currently operational GSO satellites.
It would cost about $60,000 a year to have an unencrypted global broadcast at 64kbps.

If it has anything to do with Cubesats, I would like to be a part of it. I have some experience with AGI's STK and my masters thesis has to do with Cubesat science instrumentation.
One thing that you may look at (for launch) is Nasa's ELANA deal ( part of cubesat initiative). If you can go through a university, things would be a lot cheaper.
