When receiving the history of an address, the client behaved unexpectedly if either of two checks failed. The client checked that the txids in the history are unique, and that the history matches the previously announced status. If either failed, it would just log a line and do nothing. Importantly, the synchronizer could even consider itself is_up_to_date, i.e. the GUI could show the wallet is synced. This is now changed such that: - if the txid uniqueness test fails, we simply disconnect - if the history is not consistent with previously announced status, we wait a bit, make sure is_up_to_date is False in the meantime, and then potentially disconnect See rationale for these in the comments. related: https://github.com/spesmilo/electrum/issues/7058#issuecomment-783613084

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`_.

.. _pycryptodomex: https://github.com/Legrandin/pycryptodome
.. _cryptography: https://github.com/pyca/cryptography

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
