-# Changelog — Electrum Purple
-
-All notable changes to the Electrum Purple fork are documented here.
-Upstream Electrum changes are not listed; see the [upstream changelog](https://github.com/spesmilo/electrum/blob/master/CHANGELOG).
-
----
-
-## [0.9.0] — 2026-05-06
-
-First public release of Electrum Purple — an unofficial fork of Electrum 4.7.x
-with first-class support for the **BitcoinPurple (BTCP)** network.
-
-### New network: BitcoinPurple (BTCP)
-
-- Added `BitcoinPurple` and `BitcoinPurpleTestnet` network classes with all chain
-  parameters: 1-minute blocks, 120-block difficulty retarget, adjusted PoW limits
-  (`MAX_TARGET`, `POW_GENESIS_BITS`, `DIFFICULTY_ADJUSTMENT_INTERVAL`,
-  `POW_TARGET_TIMESPAN`). (`e0d04af15`)
-- Generalized difficulty adjustment logic in `blockchain.py` to support
-  per-chain PoW constants; in-chunk retarget (120-block boundary) reads headers
-  from the in-RAM buffer instead of disk. (`d1088c036`)
-- Default network set to BitcoinPurple mainnet. (`8b8d958a4`)
-- `BIP44_COIN_TYPE` set to 13496 for BitcoinPurple. (`af1997438`)
-- Launch flags: `--bitcoinpurple` and `--bitcoinpurple_testnet`. (via constants)
-
-### Lightning Network — block-scaled timeouts
-
-- All LN timeout values expressed in blocks scaled ×10 to preserve real-world
-  security windows with 1-minute blocks (e.g. `to_self_delay` 144 → 1440,
-  `cltv_expiry_delta` 40 → 400).
-
-### UI / branding
-
-- Coin name and unit strings are now network-aware: QML and Qt GUIs display
-  the correct coin name (BTCP/BTC) based on the active network. (`d51076cb0`,
-  `5ddbb637f`, `029ec7ab2`)
-- All icons recolored blue → purple (hue 278°) to match BitcoinPurple branding.
-  (`374d1c6b6`, `12881fc47`)
-- Desktop icon (`.ico`, `.png`) updated to purple in all sizes (16 → 256 px).
-- Qt wizard logo updated to use `electrum-purple.png`. (`63e76fb08`)
-
-### Packaging and build
-
-- Package renamed to `electrum-purple`; pip entry point renamed to
-  `electrum-purple`. (`90f567d57`)
-- `setup.py` data files and PyInstaller spec updated for `electrum-purple`
-  naming. (`55f2ba258`)
-- Broken `electrum-purple` symlink fixed (was `../run_electrum`, now
-  `run_electrum`). (`4fc74d551`)
-- Desktop and metainfo files renamed to `electrum-purple.desktop` /
-  `electrum-purple.metainfo.xml`. (`729a0081a`)
-
-#### Windows
-
-- NSIS installer script renamed to `electrum-purple.nsi`; produces
-  `electrum-purple-<VERSION>-setup.exe` and `electrum-purple-<VERSION>-portable.exe`.
-  (`2a7cf8278`)
-- PyInstaller spec updated: icon set to `electrum-purple.ico`, exe name to
-  `electrum-purple-<VERSION>.exe`. (`55f2ba258`)
-- Docker build: added `--security-opt seccomp=unconfined` and
-  `--cap-add SYS_PTRACE` to fix Wine wineserver socket failure on WSL2.
-  (`f0654310e`)
-
-#### Linux AppImage
-
-- Build script updated: output renamed to
-  `electrum-purple-<VERSION>-x86_64.AppImage`. (`1a09d60a9`)
-- `apprun.sh` corrected: launches `electrum-purple` (was `electrum`). (`7e782baa7`)
-- Desktop file and icon (`electrum-purple.png`) correctly referenced in AppDir.
-- `run_electrum` `is_local` check updated to look for `electrum-purple.desktop`.
-  (`7e782baa7`)
-- type2-runtime xz pin updated. (`013d23434`)
-
-#### Android
-
-- Buildozer spec updated: `title = Electrum Purple`,
-  `package.domain = org.electrumpurple`, `package.name = electrum_purple`.
-  (`2ab945833`)
-- Java classes (`SimpleScannerActivity`, `BiometricActivity`) updated to import
-  `org.electrumpurple.electrum_purple.res.R`. (`7e782baa7`)
-
-### Bug fixes
-
-- Fixed onion message queues: replaced `put_nowait` + `sleep` polling with
-  `call_later` to eliminate busy-wait. (`9a93bfda8`)
-- Fixed flaky Lightning peer tests (retries, timeouts, MPP wait loop).
-  (`49ac312c8`, `7d433d0b4`)
-- Tests now use `config.path` instead of `electrum_path` for network-aware
-  temporary directories. (`5c406683b`)
-
-### Tests
-
-- Added full BitcoinPurple test suite: address encoding, difficulty calculation,
-  header verification, retarget clamping (46 tests). (`41e4a8141`)
-- 1005 tests pass, 6 skipped (upstream suite + BitcoinPurple suite). (`f4d2d0ade`)
-
-### Documentation
-
-- `README.md` updated: identifies this as an unofficial BitcoinPurple fork,
-  credits Davide Grilli as fork author, preserves upstream credits. (`13f8be46b`)
-- `LICENCE` updated: added Davide Grilli copyright for fork additions. (`39d65bb45`)
-- `AUTHORS` updated: Davide Grilli listed as fork author and maintainer. (`f3c376d8f`)
-- `CLAUDE.md` added with codebase and BitcoinPurple architecture documentation.
-  (`88525ef51`, `7b39a89d1`)
-- `technical-data.md` added: complete BitcoinPurple parameter reference (ports,
-  genesis, PoW, LN, ElectrumX). (`6db423282`, `a95945668`)
-- `quickstart.md` added (English). (`ea8f27358`)

-## About this fork
-
-This project is an **unofficial, independent fork** of Electrum, maintained by **Davide Grilli**.
-It adds first-class support for the **BitcoinPurple (BTCP)** network — a Bitcoin fork with
-1-minute blocks and a 120-block difficulty retarget window — while keeping full compatibility
-with the original Electrum codebase and all upstream bug fixes.
-
-This fork is **not affiliated with, endorsed by, or supported by** the original Electrum project
-or its developers. For the official Bitcoin wallet, use [electrum.org](https://electrum.org/).
-
-### What is different from upstream Electrum
-
-- `--bitcoinpurple` and `--bitcoinpurple_testnet` launch flags
-- BitcoinPurple chain parameters (1-min blocks, 120-block retarget, adjusted PoW limits)
-- Lightning Network timeouts scaled for 1-minute block times
-- Branding and packaging renamed to `electrum-purple` / `Electrum Purple`
-
-Everything else — wallet format, Lightning support, hardware wallets, plugins — is identical
-to upstream Electrum.
-
-### Licence and credits
-
-This software is released under the **MIT Licence**, the same licence as the original Electrum.
-All original copyright notices are preserved as required by the licence.
-
-Original copyright: © 2011-2024 Thomas Voegtlin and The Electrum developers.

 ## Contributing
 
-Bug reports, testing, and pull requests for BitcoinPurple-specific features are welcome.
+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.
 
-For issues unrelated to BitcoinPurple support (core wallet, Lightning, hardware wallets),
-please check the [upstream Electrum project](https://github.com/spesmilo/electrum) first —
-fixes merged upstream can be rebased into this fork.
+Besides [GitHub](https://github.com/spesmilo/electrum),
+most communication about Electrum development happens on IRC, in the
+`#electrum` channel on Libera Chat. The easiest way to participate on IRC is
+with the web client, [web.libera.chat](https://web.libera.chat/#electrum).

-- tests and coverage
+# Quickstart — Electrum (running from source)
 
 ## System prerequisites
 
 ```bash
-sudo apt update
-sudo apt install -y \
-  git python3 python3-venv python3-dev build-essential pkg-config automake libtool gettext \
-  libsecp256k1-dev libusb-1.0-0-dev libudev-dev libhidapi-dev libzbar0 \
-  libgl1 libegl1 libxkbcommon-x11-0 libxcb-cursor0 libxcb-xinerama0 \
-  libxcb-icccm4 libxcb-image0 libxcb-keysyms1 libxcb-randr0 \

+sudo apt-get install git python3.12 python3.12-venv libsecp256k1-dev xvfb
 ```
 
-Notes:
-
-- `libsecp256k1-dev` avoids recompiling secp256k1 via `electrum_ecc`.
-- `libzbar0` enables QR scanning/reading support.
-- `xvfb` is useful for GUI/QML tests on headless systems.
-- The `libxcb-*`, `libgl1`, `libegl1`, and `qt6-wayland` packages avoid common PyQt6 runtime errors on Ubuntu.
+> `libsecp256k1-dev` avoids recompiling the C library locally.
+> `xvfb` is only needed to run QML tests without a physical display.
