Problema: i server Will-Executor venivano contattati in sequenza e, su timeout, send_request riprovava 10x con sleep 3s (~130s per server morto). Un solo server irraggiungibile bloccava l'intera operazione (impallamento UI). Soluzione: - ThreadPoolExecutor: ping e push ora in parallelo (tempo ~= server piu' lento, non la somma). Un server morto non blocca piu' gli altri. - Fast-fail per operazioni interattive (ping/info/download): max_retries=0, niente retry-storm. - Feedback live: callback on_each() aggiorna il dialog server-per-server (thread-safe via pyqtSignal di BalWaitingDialog.update). - Push transazioni: parallelo ma con retry per-server mantenuti (no perdita tx). File: - bal/core/willexecutors.py: send_request(+max_retries,+retry_sleep), get_info_task fast-fail, NEW ping_servers_parallel(), push_transactions_parallel(), DEFAULT_TIMEOUT=5. - bal/gui/qt/window.py: ping_willexecutors_task + push_transactions_to_willexecutors riscritti su helper paralleli con feedback live; fetch_will_executors_list fast-fail. - bal/core/util.py: BUGFIX get_value_amount usava in_output (bool) invece di din_output (tupla) -> TypeError. Scoperto dai test ufficiali Gitea. Test (contro il codice refactor): - pytest tests/ ufficiali: 117 core + 65 gui = 182 passed. - smoke/external_zip/windows_overflow/gui_fixes: OK. - parallel_ping_test (nuovo): 0.50s per 8 server vs ~4.00s sequenziale. - ruff: nessun nuovo problema introdotto (codice nuovo PEP8-compliant). Aggiunti i test ufficiali del repo Gitea + REPORT_NETWORKING_PARALLELO.md.
BAL — Bitcoin After Life (Electrum plugin)
Free and decentralized Bitcoin inheritance support for the Electrum wallet. Build time-locked "will" transactions that transfer your funds to your heirs if you stop refreshing them (dead-man's switch), optionally relayed by will-executor servers.
This repository contains a behavior-preserving refactor of the original plugin. The logic was kept byte-identical wherever possible; only the file layout was reorganized to cleanly separate business logic from the PyQt GUI.

build_zip.py builds a clean, zipimport-friendly distribution zip
tests/ smoke + external-zip regression tests
Requirements
- Electrum 4.7.2 — the last stable release exposing
json_db.register_dict, which this plugin relies on. Newer versions removed it. - PyQt6 (bundled with the Electrum desktop GUI).
Installation
Build the distribution archive
python3 build_zip.py
# -> bal-electrum-plugin.zip (prints size + SHA-256 for integrity checks)
The builder writes a zipimport-friendly archive (files only, standard
DEFLATE, deterministic order) to avoid loader errors seen on some Electrum
portable builds.
Install as an external plugin (zip)
- Electrum → Tools → Plugins → install from file → pick the built zip.
- Enable Bitcoin After Life and restart Electrum.
- (Recommended) verify the downloaded zip's SHA-256 matches the value printed
by
build_zip.py.
Install as an internal plugin
Copy the bal/ directory into your Electrum installation's
electrum/plugins/ directory, so that electrum/plugins/bal/manifest.json
exists, then enable it from Tools → Plugins.
Testing
# imports + behavior
QT_QPA_PLATFORM=offscreen PYTHONPATH=<electrum-src> \
python3 tests/smoke_test.py electrum.plugins.bal
# external-zip loading regression
QT_QPA_PLATFORM=offscreen PYTHONPATH=<electrum-src> \
python3 tests/external_zip_test.py bal-electrum-plugin.zip
⚠️ Safety
This plugin builds real Bitcoin inheritance transactions with time-locks. Test on testnet or a fund-less wallet first, and review the generated transactions before broadcasting.
