In particular, in the regtests, with incoming peers, we can have multiple transports open with the same node simultaneously (see e.g. lnworker._request_force_close_from_backup). We now use the first few bytes of peer_pubkey, as that is potentially familiar to users, and the first few bytes of sha256(id(self)) to mitigate collisions in case the peer_pubkeys collide. log excerpt: ``` I/P | lnpeer.Peer.[LNWallet, 030f0bf260-e0b33756] | handshake done for 030f0bf260acdbd3edcad84d7588ec7c5df4711e87e6a23016f989b8d3a4147230@163.172.94.64:9735 D/P | lnpeer.Peer.[LNWallet, 030f0bf260-e0b33756] | Sending INIT I/P | lnpeer.Peer.[LNWallet, 03933884aa-5e5dce45] | handshake done for 03933884aaf1d6b108397e5efe5c86bcf2d8ca8d2f700eda99db9214fc2712b134@34.250.234.192:9735 D/P | lnpeer.Peer.[LNWallet, 03933884aa-5e5dce45] | Sending INIT D/P | lnpeer.Peer.[LNWallet, 030f0bf260-e0b33756] | Received INIT I/P | lnpeer.Peer.[LNWallet, 02651acf4a-79696c42] | handshake done for 02651acf4a7096091bf42baad19b3643ea318d6979f6dcc16ebaec43d5b0f4baf2@82.119.233.36:19735 D/P | lnpeer.Peer.[LNWallet, 02651acf4a-79696c42] | Sending INIT D/P | lnpeer.Peer.[LNWallet, 03933884aa-5e5dce45] | Received INIT I/P | lnpeer.Peer.[LNWallet, 030f0bf260-e0b33756] | saved remote_update D/P | lnpeer.Peer.[LNWallet, 030f0bf260-e0b33756] | Received CHANNEL_REESTABLISH ```

Getting started
===============
(*If you've come here looking to simply run Electrum,* `you may download it here`_.)
.. _you may download it here: https://electrum.org/#download
Electrum itself is pure Python, and so are most of the required dependencies,
but not everything. The following sections describe how to run from source, but here
is a TL;DR::
sudo apt-get install libsecp256k1-0
python3 -m pip install --user .[gui,crypto]
Not pure-python dependencies
----------------------------
If you want to use the Qt interface, install the Qt dependencies::
sudo apt-get install python3-pyqt5
For elliptic curve operations, `libsecp256k1`_ is a required dependency::
sudo apt-get install libsecp256k1-0
Alternatively, when running from a cloned repository, a script is provided to build
libsecp256k1 yourself::
sudo apt-get install automake libtool
./contrib/make_libsecp256k1.sh
Due to the need for fast symmetric ciphers, `cryptography`_ is required.
Install from your package manager (or from pip)::
sudo apt-get install python3-cryptography
If you would like hardware wallet support, see `this`_.
.. _libsecp256k1: https://github.com/bitcoin-core/secp256k1
.. _pycryptodomex: https://github.com/Legrandin/pycryptodome
.. _cryptography: https://github.com/pyca/cryptography
.. _this: https://github.com/spesmilo/electrum-docs/blob/master/hardware-linux.rst
Running from tar.gz
-------------------
If you downloaded the official package (tar.gz), you can run
Electrum from its root directory without installing it on your
system; all the pure python dependencies are included in the 'packages'
directory. To run Electrum from its root directory, just do::
./run_electrum
You can also install Electrum on your system, by running this command::
sudo apt-get install python3-setuptools python3-pip
python3 -m pip install --user .
This will download and install the Python dependencies used by
Electrum instead of using the 'packages' directory.
It will also place an executable named :code:`electrum` in :code:`~/.local/bin`,
so make sure that is on your :code:`PATH` variable.
Development version (git clone)
-------------------------------
Check out the code from GitHub::
git clone git://github.com/spesmilo/electrum.git
cd electrum
git submodule update --init
Run install (this should install dependencies)::
python3 -m pip install --user -e .
Create translations (optional)::
sudo apt-get install python-requests gettext
./contrib/pull_locale
Finally, to start Electrum::
./run_electrum

Contributing
============
Any help testing the software, reporting or fixing bugs, reviewing pull requests
and recent changes, writing tests, or helping with outstanding issues is very welcome.
Implementing new features, or improving/refactoring the codebase, is of course
also welcome, but to avoid wasted effort, especially for larger changes,
we encourage discussing these on the issue tracker or IRC first.
Besides `GitHub`_, most communication about Electrum development happens on IRC, in the
:code:`#electrum` channel on Libera Chat. The easiest way to participate on IRC is
with the web client, `web.libera.chat`_.
