CHECKDATASIG/MUL Coin splitter

Licence: MIT Licence
Author: Mark B. Lundeberg
Language: Python

This is a special release of Electron Cash augmented with a coin-splitting tool for the November 2018 Bitcoin Cash hard fork. The tool can be started via:

• Tools menu | Coin splitter, or,
• Addresses tab: right-click on an address | Split coins.

By using this tool, you can create transactions built on a history involving the new OP_CHECKDATASIGVERIFY. Such transactions are impossible to replay on other nodes / chains that do not support this opcode. In a secondary mode, you can also create OP_MUL-based splitting, though with some limitations.

A detailed usage guide can be found here: doc/coinsplitter_user_guide.md (中文版请访问这个链接：doc/CoinSplitterUserGuide_CN.md)

Since Electron Cash 3.3.3, the mainline client has been checkpointed so as to only connect to BCH servers. In contrast, this release is being maintained up-to-date but with the checkpointing reverted, and with a healthy list of BSV servers included, so you can connect to both BCH and BSV. Enjoy!

For the technically inclined / curious, the primary code additions appear in this file and this file.

Standard instructions for Electron Cash (the base software) follow:

Electron Cash - Lightweight Bitcoin Cash client

Licence: MIT Licence

Language: Python

Getting started

Electron Cash is a pure python application forked from Electrum. If you want to use the Qt interface, install the Qt dependencies:

sudo apt-get install python3-pyqt5

If you downloaded the official package (tar.gz), you can run Electron Cash from its root directory (called Electrum), without installing it on your system; all the python dependencies are included in the 'packages' directory. To run Electron Cash from its root directory, just do:

./electron-cash

You can also install Electron Cash on your system, by running this command:

sudo apt-get install python3-setuptools
python3 setup.py install

This will download and install the Python dependencies used by Electron Cash, instead of using the 'packages' directory.

If you cloned the git repository, you need to compile extra files before you can run Electron Cash. Read the next section, "Development Version".

Development version

Check out the code from Github:

git clone https://github.com/Electron-Cash/Electron-Cash
cd Electron-Cash

Run install (this should install dependencies):

python3 setup.py install

Compile the icons file for Qt:

sudo apt-get install pyqt5-dev-tools
pyrcc5 icons.qrc -o gui/qt/icons_rc.py

Compile the protobuf description file:

sudo apt-get install protobuf-compiler
protoc --proto_path=lib/ --python_out=lib/ lib/paymentrequest.proto

Create translations (optional):

sudo apt-get install python-requests gettext
./contrib/make_locale

For plugin development, see the plugin documentation.

Running unit tests:

pip install tox
tox

Tox will take care of building a faux installation environment, and ensure that the mapped import paths work correctly.

Creating Binaries

To create binaries, create the 'packages/' directory:

./contrib/make_packages

This directory contains the python dependencies used by Electron Cash.

The make_packages command may fail with some Ubuntu-packaged versions of pip ("can't combine user with prefix."). To solve this, it is necessary to upgrade your pip to the official version:

pip install pip --user

Linux (source with packages)

Run the following to create the release tarball under dist/:

./setup.py sdist
