Minimalistic python implementation of the Bitcoin networking stack. This library was developed to facilitate measurements in the Bitcoin network for some of my papers. It does include everything that is needed to connect and participate in the network, it does however not contain any crypto implementations other than the checksum mechanism. If you find this work useful please contribute back your modifications or give me a shout. Should you have a nice idea for a project, we're always looking for fun stuff to implement.
To install just checkout the git repository and use the included
setup.py script to build and bundle it:
git clone git@github.com:cdecker/pycoin.git
python setup.py installThe following example creates a connection pool. It rewires the
message handler on each connection to call the on_inv_received
handler on the InvTracker instead, adding the connection as
additional argument. When receiving an inv message it loops through
the hashes and prints their type and hash to stdout.
from bitcoin import network
def on_inv_received(connection, inv):
for item in inv.hashes:
print connection.host, item[0], item[1].encode("hex")
def start():
client = network.GeventNetworkClient()
client.register_handler('inv', on_inv_received)
network.ClientBehavior(client)
client.connect(('seed.bitcoinstats.com', 8333))
client.run_forever()

start()v0.1
This release breaks some of the existing functionality and moves networking code into the bitcoin.network package. The twisted implementation is currenty broken since I concentrate mainly on gevent for my own clients.
v0.1.1 Added listening for incoming connection to GeventNetworkClient.
v0.2
- Removed legacy twisted API
- Increased test coverage (py.test)
- Code is now PEP8 compliant
v0.2.1 Minor bugfix release.
- Added six dependency for compatibility
- Fixed parsing of relay flag in
versionmessage - Bumped gevent dependency to allow support for python 3 in some distant future
