GRS September 2022 Release Update

With a global rising cost-of-living crisis, cryptocurrency is currently seeing its greatest challenge yet. Satoshi Nakamoto created Bitcoin in light of the last financial crisis in 2008 in an effort to provide an alternative, unregulated, market-controlled currency. The western world is now on the brink of another financial crisis, with the aftermath of government Covid-19 contingency efforts and now the Ukraine-Russia war putting strains on people's wallets, the next couple of years will prove or disprove the fundamental idea of cryptocurrency. It currently appears the world of cryptocurrency is slightly in “limbo”, waiting for how everything pans out and that is largely reflected in the price movements of Bitcoin, Ethereum, GRS and other cryptocurrencies over the past few months.

GRS has been fairly resilient over the course of the past few months, despite unfortunately being unfairly delisted from Binance, which highlighted further the requirements of being available on as many exchanges as possible, big or small. GRS has weathered the storm and will come out of it stronger.

Did you know?

GRS is rated #6 for active Github contributions in the last 12 months, and rated #10 in the last 3 months!

Once again there have been significant technological pushes over the past few months that will be announced below.

C-Lightning 0.12.0

Electrum GRS 4.3.1 Update (Mainnet + Testnet)

Click here for more information, download links and more for Electrum-GRS

What’s New? (Android-Specific)

  • fix “Child Pays For Parent” not working on Android
  • Revert to defaulting the UI language to English
  • Bring kivy request dialog more in-line with Qt
  • kivy: fix deleting “local” tx from history
  • kivy: fix paying amountless LN invoice
  • kivy: dust-valued requests could not be created for LN.

What’s New? (Server & Desktop)

This version introduces a set of UI modifications that simplify the use of Lightning. The idea is to abstract payments from the payment layer, and to suggest solutions when a lightning payment is hindered by liquidity issues:

  • Invoice unification: on-chain and lightning invoices have been merged into a unique type of invoice, and the GUI has a single ‘create request’ button. Unified invoices contain both a lightning invoice and an onchain fallback address.
  • The receive tab of the GUI can display, for each payment request, a lightning invoice, a BIP21 URI, or an onchain address. If the request is paid off-chain, the associated on-chain address will be recycled in subsequent requests.
  • The receive tab displays whether a payment can be received using Lightning, given the current channel liquidity. If a payment cannot be received, but may be received after a channel rebalance or a submarine swap, the GUI will propose such an operation.
  • Similarly, if channels do not have enough liquidity to pay a lightning invoice, the GUI will suggest available alternatives: rebalance existing channels, open a new channel, perform a submarine swap, or pay to the provided onchain fallback address.
  • A single balance is shown in the GUI. A pie chart reflects how that balance is distributed (on-chain, lightning, unconfirmed, frozen, etc).
  • The semantics of the wallet balance has been modified: only incoming transactions are considered in the ‘unconfirmed’ part of the balance. Indeed, if an outgoing transaction does not get mined, that is not going to decrease the wallet balance. Thus, change outputs of outgoing transactions are not subtracted from the confirmed balance. (Before this change, the arithmetic values of both incoming and outgoing transactions were added to the unconfirmed balance, and could potentially cancel each other.)

Exchanges:

  • Added Coinbase Exchange pricing information
  • Removed Binance Exchange pricing information

Binaries:

  • Dropped support for Windows 7
  • Bump bundled Python version (win, mac, appimage) to 3.9.11, (android) to 3.8.13. (note these include a fix to an openssl DOS-vector CVE-2022–0778)
  • Windows: bump pyinstaller to 4.10 and wine to 7.0.
  • Appimage: fix the “ — portable” flag for AppImage, and for pip installs.
  • Appimage: fix AppImage failing to run on certain systems.
  • Source-only: we now also distribute a “source-only” Linux-packager-friendly tarball, in addition to the current “normal” tarball. The “source-only” tarball excludes compiled locale files, and generated protobuf files, and does not vendor our runtime python dependencies (the packages/ folder).
  • Linux: fix os.chmod when running in tmpfs on Linux.

QT GUI:

  • macOS: fix opening “Preferences” segfaulting for some.
  • More resilient startup: better error handling and fallback.
  • Some improvements for high-DPI monitors.
  • Fix duplication of some OS notifications on onchain txs.
  • Better handle unparseable URIs.

Library:

  • Fix LN error/warning message-handling, and fix regression that errors during channel-open were not properly shown in GUI.
  • During LN channel open, do not backup wallet automatically.
  • Imported wallets: fix delete_address removing too many txs.
  • Fix potential deadlock in wallet.py.
  • Fix “Automated BIP39 recovery” not scanning change paths.
  • Labels of payment requests were not propagated to history/addresses.
  • Better default labels of outgoing txs.
  • Bypass network proxy for localhost electrum server.
  • Security fix: remove support of “file://” URIs from BIP70 payment requests, which could be used to trigger “open()” on arbitrary files (see https://github.com/spesmilo/electrum/security/advisories/GHSA-4fh4-hx35-r355)

Hardware Wallets:

  • Ledger: add progress indicator to sign_transaction.
  • Smarter pairing during sign_transaction.
  • Keepkey: fix pairing with the device using a workaround.

Lightning:

  • Watching onchain outputs: significant perf. improvements.
  • Enforce relative order of some msgs during chan reestablishment, lack of which can lead to unwanted force-closures.
  • Fix: in case of a force-close containing incoming HTLCs, we were redeeming all HTLCs that we know the preimage for. This might publish the preimage of an incomplete MPP.
  • Support for LNURL-pay (LUD-06)
  • Updated trampoline feature bit in invoices.
  • The claim transactions of reverse swaps are not broadcast until the parent transaction is confirmed. This can be overridden by manually broadcasting the local transaction.
  • The fee of submarine swap transactions can be bumped.
  • Better error handling for trampoline payments, which should improve the payment success rate.
  • Channel backups are removed automatically when the corresponding channel is redeemed.
  • Remove support of “legacy” (without static_remotekey) LN channels. Opening these channels was never supported in a release version, only during development prior to the first lightning-capable release. Wallets with such channels will have to close them.
  • Handle NotEnoughFunds when trying to pay LN invoice.
  • Handle NotEnoughFuds when trying to open LN channel.
  • When closing LN channels, future (timelocked) txs were not shown in history.
