1  Economy / Collectibles / Super Bitcoiner Keychain (Open Source) on: February 09, 2016, 04:45:12 AM

As a fun project I started designing a keychain that I would like, and to be honest I love the end result.

It's 10 USD payable with Bitcoin (Shipping included, Worldwide).
You can see more information and buy it at:

Here are a few pictures of the keychain:

I'm only selling them with Bitcoin or give them for free to anyone that I believe is a true Bitcoiner, Just for the fun of having a secret community Smiley

P.S. If you think you are a real bitcoiner and have done real work in this sphere, let me know and I'd be happy to send one free of charge for you.
2  Bitcoin / Bitcoin Discussion / The first Montreal Cafe to accept Bitcoin on: October 23, 2014, 12:30:40 AM

Café Aunja – 1448 Sherbrooke West

It’s around a cup of coffee that My Dear Montréal was born.
A warm ambiance, a vintage decor, a welcoming staff and a lulling melody; we almost feel like home.
Café Aunja offers a healthy menu that changes at the whim of the seasons, refreshing drinks and a large variety of oriental tea.
Grade: 9/10

Cafe Aunja is the first and only cafe in Montreal that accepts Bitcoin, located at 1448 Sherbrooke West (Google Map), Downtown, Montreal. This place best described by Google: “Cozy basement-level Persian tea & coffee spot offering sweets, art on the walls & live music.
Also there is a 10% discount if you pay by bitcoin Smiley

“Everything about his place makes you want to loose track of time and wonder about the meaning of life (until you find it). The front space welcomes a new exhibition or performance every other day, while the back end, filled with a large couch, is a cosy haven for the intellect at work. Should you need a little dose of caffeine to keep up with conversation, Cafe Aunja has you covered with over 60 varieties of dried flowers and teas to mix into your very own hot drink. Every teapot is served with a few Persian chickpea cookies (Nan-e Nokhodchi) that literally melt in your mouth. So really, you have no reason to leave.”

3  Bitcoin / Meetups / Tehran, Iran Cryptocurrency Workshop/Meetup on: May 27, 2014, 01:52:02 AM
I’m going on a trip to Tehran, Iran and planning to hold a Bitcoin workshop/meetup in Tehran by mid-summer.

I was wondering if anyone has any experience doing such a thing for their own community to get some tips or maybe slides/materials for the newbies and people that are interested but may not have the technical background, in finance nor computers.

I've been running forum and blog ( for over 1.5 years now (localized in Persian) and have gathered some people around since. My estimation is that there would be around 50+ people, I might print out some stickers or catalogues to hand out too.
Also, if anyone is interested to distribute their commercial goods in this meeting, contact me via private message or email me at info at btctalk dot com (preferably as soon as possible cause I got to have them shipped to Tehran on time)

My main goal for this workshop is to introduce what bitcoin and other cryptocurrencies are and transparency of information, also to get Bitcoin enthusiast together to have a community to keep the meetups going.

I’d try to make a video of the whole presentation and workshop to have it online for people who could not attend.

I've read lots of Farsi articles on Bitcoins related subjects and there are a lot of mistakes and false facts, more than you'd think, circling around in Iranian community, such as some conspiracy theories regarding Bitcoin (lol?)

Any suggestions or critics on the idea would help.

Thank you,

p.s. any donation would be greatly appreciated as I have to rent a place and the fees for the catalogues and all.
I would thank all the donors at the meeting (Video/Photos will be provided to donors in case it’s needed Smiley )

4  Bitcoin / Project Development / Wallet Convertor on: December 01, 2013, 07:24:05 AM

I had a really hard time converting my Bitcoin-QT wallet.dat files to something that is possible to import to Multibit Wallet. (Not that hard but stupid to go all that way for something that should have been simple)
So I ended up writing a python program to do so from now on.

Github :


Bitcoin Wallet Convertor (for now) 1.0 reads the keys from Bitcoin-QT wallet (e.g wallet.dat) and exports them to MultiBit wallet format (e.g multibit.key) but also applicable for imports. In short it's a bitcoin wallet convertor from wallet.dat to multibit.key.

I used jackjack-jj fork of ( to read wallet.dat and it is included in this repository. so you need to install the pywallet dependencies prior to the use of this.

Why should I use this?

To Convert your wallet.dat (or exported wallet from Bitcoin-QT) to:

  • MultiBit Wallet
  • Blockchain Importable format
  • Backup your private keys in a format that would not be as complicated as wallet.dat and less possible to be corrupted

WARNING: the output is not encrypted so take good care of the file!


Usage: [options]


--version show program's version number and exit

      -h, --help show this help message and exit

      --wallet=Wallet                    wallet.dat or the exported wallet from Bitcoin-QT to be converted

      --newwallet=NewWallet          New wallet name (multibit format) (in the same directory as the --wallet


              ./ --wallet ./wallet.dat

              ./ --wallet ./wallet.dat --newwallet ./newwallet.key


  • Less dependencies to
  • Add --passphrase to read encrypted wallet.dat
  • Nicer code! for now it works fine but it could be implemented in less hacky-code style
  • Should be tested on windows too (tested on Mac and Linux so far)
  • Add the other way convertion (Using Import Private keys of
  • Define a standard for wallet format as .OWF


Please support the work by either writing code or donate to 1owfJHTsWrrCpgaaYjC1vbJevuQzYRTYn
It would be greatly appreciated.

I'm going to renew this domain in a week or so, but I really don't have a use for it, and prefer to bitcoin it Smiley

Price is negotiable, although if you got your bitcoins when it was around $12 or even less, help me out on this cause I sold most of mines in those days, Can't say I don't regret... Smiley
6  Economy / Service Discussion / Who is fuzzing users? [HACK ATTEMP] on: September 25, 2013, 06:48:32 AM
I had this in mind a while ago but I guess someone finally did this.

Today I received an email saying:

Authorize log-in attempt

An attempt to login to your wallet was made from an unknown browser. Please confirm the following details are correct:

Time: 2013-09-25 03:16:43
IP Address: (United States)
User Agent: Python-urllib/2.7

It's a while that I haven't used my wallet in any forms (chrome plugin, mobile app, etc)
As the Python-urllib says, it's a script doing this login from a probably proxy with the specified ip.

something fishy is going on in shirt! secure your accounts Wink
