python-obelisk's Introduction

Darkwallet

We love Bitcoin, and the power it gives for trade and social connections. There is so much untapped power in Bitcoin. You know the saying "we only use 10% of our brain's power"? We probably use less than 1% of what is possible with Bitcoin!

We want to start with a simple premise: Bitcoin in your browser. We want a beautiful experience with privacy features built in by default.

This wallet will serve as a platform or a starting codebase to deliver a high quality Bitcoin that serves the people.

Running

You can load the extension into Chrome by going to Extensions, enabling Development mode and clicking the Load uncompressed extension button.

Alpha!!!

We're still in alpha state, that means we're still changing things a lot and it's not safe at all to use the wallet. More information at: https://wiki.unsystem.net/index.php/DarkWallet/Alpha

You are very welcome to test, just remember the following:

Write down your seed and be always ready to use it to restore the identity.
First thing you should do is get familiar with creating and restoring an identity.
You can do: "create new identity", choose same name as before and restore, this will upgrade your store (you will still need to re add pockets and addresses, contacts etc...)
If you notice strange behaviour after upgrading, you should:
1. Restart the background process from darkwallet (from "manage extensions")
2. If that doesn't work: Clear Darkwallet storage, (from darkwallet settings), restart chromium

We have been following this procedure since the wallet is under development without problems.

Remember: Your funds are safe as long as you don't lose your seed to restore later.

Other than that we're not making many guarantees.

Development

I went to the store the other day to buy a bolt for our front door, for as I told the storekeeper, the governor was coming here. "Aye," said he, "and the Legislature too." "Then I will take two bolts," said I. He said that there had been a steady demand for bolts and locks of late, for our protectors were coming.

python-obelisk's Issues

module is build against old version of pyzmq.

I'm trying to build our http gateway, what version of pyzmq do you have? There's some changes in the module layout, meaning i get error messages like.

  File "obelisk/zmq_fallback.py", line 27, in poll
    except zmq.core.error.ZMQError:
exceptions.AttributeError: 'module' object has no attribute 'core'

Ubuntu raring is v2.2.0 http://packages.ubuntu.com/raring/python-zmq,
saucy (13.10) is now 13.1.0 and newest in pip/trusty is 14.0.1

The error module is now in the root of the module, so it's just;
zmq.error.ZMQError

Since we'll probably be shipping with support for 13.10 onwards, this is the version we should target, I'll update the references tomorrow, just a heads up.

In [6]: zmq.__version__
Out[6]: '14.0.1'

Creat pip package

Create an installable pip package for python-obelisk. Self-explanatory.

problem installing python

hello team, i am using kali linux 64 and i am explaining below problems with installation
telling you everything step by step what i did and what i get
# apt-get install python-pip python-twisted
python-pip is already the newest version.
python-twisted is already the newest version.

          # pip install ecdsa
        Requirement already satisfied (use --upgrade to upgrade): ecdsa in /usr/local/lib/python2.7/dist-packages

Cleaning up...

           # apt-get install cython
           Reading state information... Done

cython is already the newest version.
and cython version Cython version 0.19.1

then the next step
$ wget "https://github.com/zeromq/pyzmq/releases/download/v14.1.1/pyzmq-14.1.1.tar.gz"

             there was some problem there with downloading it in terminal
              Resolving s3.amazonaws.com (s3.amazonaws.com)... failed: Name or service not known.
               wget: unable to resolve host address `s3.amazonaws.com'

             so i downloaded it from from browser and followed again

             user@localhost:~$ cd Downloads
             user@localhost:~/Downloads$ tar xf pyzmq-14.1.1.tar.gz
             user@localhost:~/Downloads$ cd pyzmq-14.1.1
             user@localhost:~/Downloads/pyzmq-14.1.1$ 
             user@localhost:~/Downloads/pyzmq-14.1.1$ python setup.py configure --zmq=/usr/local/
   so i get here this : 

running configure

please help what shall i do next.
thank you.

Threat model of python-obelisk

As python-obelisk is a core part of OpenBazaar, I wanted to inquire about the threat model behind the obelisk protocol and how much of it is inherited in the python-obelisk client. In particular, how much trust does the python-obelisk client give to the obeliskd, and what is the server capable of doing under these assumptions?

Clearly, a malicious obeliskd could deny service. However, is it possible that they fake transactions, transaction amounts, and generally respond with inaccurate data in a way that the client isn't able to detect?

Thanks for your input.

python-ecdsa breaks compatibility

The latest release of python-ecdsa
tlsfuzzer/python-ecdsa@80bdce1 changed the number of arguments for ecdsa.curves.Curve which is used in https://github.com/darkwallet/python-obelisk/blob/master/obelisk/bitcoin.py line 315
I was going to re-write the code to check for ecdsa package version and change the number of arguments accordantly, but I thought I'd check here first.

Thoughts ?

Recursion Bug when fetching too much data

When socket reads too much data, ZmqSocket fails with a "maximum recursion error".

Please fix zmq_fallback.py from recursion to iterative like this:

def poll(self):
    while True:
        try:
            data = self._socket.recv(flags=zmq.NOBLOCK)
        except zmq.error.ZMQError:
            return
        more = self._socket.getsockopt(zmq.RCVMORE)
        self._cb(data, more)

Add namecoin support to obelisk

As part of OpenBazaar, we plan to use namecoin to query user-friendly names associated with markets. To verify authenticity of names, we wish to query the namecoin blockchain. Obelisk would be the ideal way to do this. Are there any plans to incorporate such queries into the protocol?

Sequence with wrong messages 1

Testing out the pubsub example, and I get lots of Sequence with wrong messages 1 errors.

Looks like the transaction_received method is being called, but only the raw tx is in _messages, the hash isn't present.
