Bitcoin server running on an N900
 

If anyone is using Bitcoin, the distributed digital currency, you can now run the Bitcoin server on your N900, thanks to a port by user doublec at the Bitcoin forum.

You can read about it and download the executable from here:
http://www.bitcoin.org/smf/index.php?topic=2125

This is the non-gui version of Bitcoin (the GUI version uses the wxWidgets library and will be harder to port). Here's how it looks:

loving my N900 sooo much due to this very kind of thing...thanks for finding it!

Re: Bitcoin server running on an N900
 

how much battery charge is lost by leaving this running in the background?

Re: Bitcoin server running on an N900
 

I only run it when plugged in to the charger or to a USB socket. But I'm one of those who has never been able to get a full day out of the N900 battery if I leave WiFi on.

Power consumption is very heavy for the first six hours while Bitcoin is downloading the cryptographically-signed block chain. You absolutely can't do that bit on battery power, nor can you do coin generation on battery power.

If you're just doing transactions, the data "chatter" is fairly light and I don't think it would be a battery life dealbreaker.

The page is gone now, but seeing as there is an armel package of bitcoind in Debian, what would porting to fremantle or harmattan take?

Is there a guide on porting from Debian to Maemo? I know of optify, but didn't find much more. (Well, there's scratchbox)

Re: Bitcoin server running on an N900
 

There is no point mining with a N900 even if you could time travel back to the early days and mine the easy hashes, now you wouldn't even mine one block as faster miners would claimjump your blocks every time until the heat death of the universe, your wasted batteries and CPU cycles would just add to the wasted enthropy.
Use this console app as designed for a portable bitcoin wallet, write a QT app if you want a nice GUI frontend.
If you want to get fancy get a square brand credit card reader and utilize the magread app code to add ability to convert national currency to bitcoin so you can accept a credit card for a mobile point of sale.

Re: Bitcoin server running on an N900
 

I don't think anyone is seriously considering to use their phones to mine for bitcoin.

But as a mobile payment tool, I'd love it.

Re: Bitcoin server running on an N900
 

A silly calculation.
Based on http://blockexplorer.com/q/nethash - I make the difficulty at the time of release about 600, rising to 1200 a month later.

At current prices - if you had started bitcoind when the original release was posted in this thread on your n900, and then left it running for about 3 months, you would have around 3 bitcoins likely by now, worth about $3000.

Re: Bitcoin server running on an N900
 

Hey! Just running bitcoind can earn you bitcoins? Without mining?

Re: Bitcoin server running on an N900
 

No. You need to mine to earn bitcoin. But still, as said above, don't bother; even in shared mining pools and even if you have free (to you) power, you'll still not make enough to make it worth it, and probably shorten the life of your hardware noticably.

Re: Bitcoin server running on an N900
 

The only way to realistically mine anymore is using video cards with special drivers working in a mining pool. From what I understand most mining anymore is done with supercomputing clusters on behalf of Wall Street hedge funds.

Best quote from the bitcoin dev thread in 2010
In 2010 N900 = $600US
in 2013 100BTC =~$10,000US

A bit off of the thread topic, but has anyone seen this?
https://bitpay.com/960000/donate
a Bitpay appeal for donations to the Maemo community, is this legit?

Re: Bitcoin server running on an N900
 

never seen it, and it's hard to tell how legit or not it may be..
BTW there's a Maemo eV general assembly coming up, so please please anyone who's a member or wants to be one needs to be there.

Re: Bitcoin server running on an N900
 

Oops. https://talk.maemo.org/showthread.php?t=95856
The donation address is good!

Re: Bitcoin server running on an N900
 

Unfortunately that is not true any longer!
The bitcoin handler Bitpay has terminated our account for not being used and we currently cannot receive bitcoin donatins.

Re: Bitcoin server running on an N900
 

Why not just have the board make a new wallet and post the receive QR code?

I really hate the concept of storing crypto in an institutional wallet where they can abuse it in all ways that holding a real crypto wallet is immune from. It is the difference between holding cash or gold in a sketchy uninsured vault owned by some rando guy with a generally bad reputation who is always hounded by a corrupt asset seizing government vs your own hidden vault or buried treasure chest. I suppose the concern is anyone with the spend keys could empty the wallet vs a organizational bank account with two signers.

I am sure there is any number of cool zero-trust ways to set up a split key layer cryptographic sum interface so any two or three fractional key holders from the collected Maemo officers could combine to send a 'spend' command to the blockchain for the main wallet. If not there has to be any number of maths PhD candidates who would love to hack that challenge for a published paper and it would be quite useful to any number of organizations who wish to dump banks.(yes there are various problems with each crypto currency as well as volatility vs fiat currency).

Re: Bitcoin server running on an N900
 

As far as I understand the reason to choose an institutional provider was to enable immediately converting the bitcoin donations to euros and transferring then to our bank account, preserving the paper trail in doing that.

The board has no intention in hoarding assets as bitcoins so this was the simple solution.

It just turned out not to be that good as it indeed left us in the mercy of the exchange ageny that could terminate our account just like that.

Re: Bitcoin server running on an N900
 

Yea...
It is the musings of someone who wishes that we could live in a world without the suspicion and reality of fraud.
The on/off ramps between crypto and cash are the arreas with the most friction. I hope the receiver wallet is not still active and funneling any Maemo donations into blockexplorer pockets though.

Re: Bitcoin server running on an N900
 

I've been running a home-based bitcoin server on an N900 (Cortex-A9 ARM processor) for a few months now. So far, the experience has been pretty good. Lets We researched and tested each of the cryptocurrencies and here is our experience about the casino. The device is cheap ($80), small enough to fit in my pocket and has enough horsepower for my needs. With the price currently hovering at about $100 the device is actually becoming quite affordable for those who don't have a lot of money to throw away on hardware.

Re: Bitcoin server running on an N900
 

ArthurT41, your very first post on TMO is spamming your crypto casino.
Please report his post and I will delete mine once ArthurT41's is gone.

Re: Bitcoin server running on an N900
 

I reported it the day it was posted, seems no-one cares :(

Re: Bitcoin server running on an N900
 

It should only need one more report to delete the post (linked below) for spam.
