Groestlcoin 22nd September Release

Groestlcoin Release September 2022

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, Groestlcoin and other cryptocurrencies over the past few months.

Groestlcoin 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. Groestlcoin has weathered the storm and will come out of it stronger.

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

What’s Being Released Today?

 

GROESTLCOIN DEVELOPMENT RELEASE

Electrum-GRS v4.3.1

What am I?

If you are an ordinary user of Groestlcoin and simply want the convenience of a web wallet with the security of a real application and support for multi-signature, then Electrum-GRS is the right choice for you.

Changelog Electrum-GRS 4.3.1

  • 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.)
  • Exchange
    - Added Coinbase exchange
    - Removed Binance exchange
  • Binaries:
    - Windows: we are dropping support for Windows 7. Version 4.2.0 already unintentionally broke compatibility with Win7 and there is no easy way to restore and maintain support. Existing users can keep using version 4.1.5 for now, but should consider upgrading or changing their OS. Win8.1 still works but only Win10 is regularly tested.
    - 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, 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 chan 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 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 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 were 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.

Features

  • Multi-currency- GRS Bluewallet supports more than 20 currencies, including USD, AUD, BRL, CAD, CHF, CZK, CNY, EUR, GDP, HRK, INR, JPY, MXN, MYR, or RUB.
  • Multi-language - GRS Bluewallet supports more than 20 languages, including Chinese, Japanese, Portuguese, Spanish, Indonesian, Russian, Ukranian, Italian, German, Swedish, Norwegian, French, Danish or Turkish.
  • Export TXHEX - You can get your transaction HEX (TXHEX) without broadcasting it, and only do it with the relay of your choice.
  • Be in control - On your Groestlcoin wallet your private keys never leave your device. You are in full control of your private keys. You can at any moment generate backups and export/import your wallets, with full control of what to do with your private keys.
  • Multiple wallets support - GRS Bluewallet aims to support the maximum wallet standards. Currently supported: BIP44 (HD), BIP49 (HD SegWit), BIP84 (HD bech32, native SegWit), BIP39 Groestlwallet-compatible (m/0'/0/0), Legacy single-address, SegWit single-address (P2SH). You can have many wallets in a single app at the same time.
  • HD wallets - The Hierarchical Deterministic (HD) key creation and transfer protocol (BIP32), which allows creating child keys from parent keys in a hierarchy. The HD Wallets will generate you different public keys for each transactions.
  • SegWit - SegWit supported in P2SH-compatibility mode and bech32 Native mode. Segwit was a massive upgrade to the Groestlcoin Protocol released in 2017. You will find all wallets with SegWit enabled by default.
  • Full encryption - On top of the phone multi-layer encryption, GRS Bluewallet can encrypt everything with an added password. Biometric security (touch ID, Face ID) is not safe, so you will have an additional password to encrypt your wallet instead.
  • Plausible deniability - A custom made feature thinking about your personal security. GRS Bluewallet allows you to define a different password which will decrypt a fake wallet set up. For any situation you are forced to disclose your access or when you don't want or you can't show your real wallet.
  • Open Source - GRS Bluewallet is built on a public repo, up-to-date and available on the Groestlcoin GitHub. This means that any user can build it and run it on his own, without any custodial dependencies. Verify the code and contribute to the wallet development.

  • Be in control - On your Groestlcoin wallet your private keys never leave your device. You are in full control of your private keys. You can at any moment generate backups and export/import your wallets, with full control of what to do with your private keys.
  • Multiple wallets support - GRS Bluewallet aims to support the maximum wallet standards. Currently supported: BIP44 (HD), BIP49 (HD SegWit), BIP84 (HD bech32, native SegWit), BIP39 Groestlwallet-compatible (m/0'/0/0), Legacy single-address, SegWit single-address (P2SH). You can have many wallets in a single app at the same time.

For any situation you are forced to disclose your access or when you don't want or you can't show your real wallet.

Groestlcoin Eclair 0.7.0

What am I?

Groestlcoin Eclair is a Scala implementation of the Lightning Network. It runs without a GUI and includes a JSON API.

Requirements

  • Groestlcoin Eclair requires Groestlcoin Core 22.0 or higher. If you are upgrading an existing wallet, you need to create a new address and send all your funds to that address.
  • Groestlcoin Eclair needs a synchronized, segwit-ready, zeromq-enabled, wallet-enabled, non-pruning, tx-indexing Groestlcoin Core node.
  • Groestlcoin Eclair will use any GRS it finds in the Groestlcoin Core wallet to fund any channels you choose to open. Eclair will return GRS from closed channels to this wallet
  • You must configure your Groestlcoin node to use bech32 (segwit) addresses. If your wallet has "non-segwit UTXOs" (outputs that are neither p2sh-segwit or bech32), you must send them to a bech32 address before running eclair.

Changelog 0.7.0

  • Eclair now supports cookie authentication for Groestlcoin Core RPC.
  • Eclair echoes back the remote peer's IP address in init.
  • Eclair now supports circular rebalancing.
  • Anchor outputs activated by default.
  • Postgres database backend graduates to production-ready.
  • Alternate strategy to avoid mass force-close of channels in certain cases.
  • Separate log for important notifications.
  • Support for onion messages.
  • Support for option_payment_metadata.
  • Optional safety checks when using Postgres.

Features

  • Ability to create Lightning Network channels
  • Ability to close Lightning Network Channels
  • Completely manage all channel states, including exceptional ones!
  • Supports both Mainnet and Testnet
