Groestlcoin Development & Technical Discussion / GRSPay v1.5.4.0 released
Last post by jackielove4u - June 22, 2022, 08:50:34 PM

GRSPay: a free and open-source cryptocurrency payment processor which allows you to receive payments in Groestlcoin with no fees, transaction cost or a middleman.


GRSPay is a non-custodial invoicing system which eliminates the involvement of a third-party. Payments with GRSPay go directly to your wallet, which increases the privacy and security. Your private keys are never uploaded to the server. There is no address re-use, since each invoice generates a new address deriving from your xpubkey or zpubkey.

Groestlcoin Development & Technical Discussion / C-lightning 0.11.1 released
Last post by jackielove4u - June 22, 2022, 08:48:57 PM

C-lightning: A specification compliant Lightning Network implementation in C


C-lightning is a lightweight, highly customizable and standard compliant implementation of the Lightning Network protocol.
C-lightning only works on Linux and Mac OS, and requires a locally (or remotely) running groestlcoind (version 2.16.0 or above) that is fully caught up with the network you're testing on.

Changelog 0.11.1
• Protocol: we now support opening multiple channels with the same peer.
• Protocol: we send/receive IP addresses in init, and send updated node_announcement when two peers report the same remote_addr (disable-ip-discovery suppresses this announcement).
• Protocol: we more aggressively send our own gossip, to improve propagation chances.
• Plugins: cln-grpc first class GRPC interface for remotely controlling nodes over mTLS authentication; set grpc-port to activate.
• Database: With the sqlite3:// scheme for --wallet option, you can now specify a second file path for real-time database backup by separating it from the main file path with a : character.
• Protocol: pay (and decode, etc) supports bolt11 payment_metadata a-la lightning/bolts#912
• JSON-RPC: invoice has a new parameter deschashonly to put hash of description in bolt11.
• JSON-RPC: pay has new parameter description, will be required if bolt11 only has a hash.
• JSON-RPC: pay has new parameter maxfee for setting absolute fee (instead of using maxfeepercent and/or exemptfee)
• JSON-RPC: listforwards has new entry style, currently "legacy" or "tlv".
• JSON-RPC: delinvoice has a new parameter desconly to remove description.
• JSON-RPC: new setchannel command generalizes setchannelfee: you can now alter the htlc_minimum_msat and htlc_maximum_msat your node advertizes.
• Config: htlc-minimum-msat and htlc-maximum-msat to set default values to advertizes for new channels.
• JSON-RPC: listpeers now includes a pushed_msat value. For leased channels, is the total lease_fee.
• JSON-RPC: getinfo result now includes our_features (bits) for various Bolt #9 contexts
• Docker build for ARM defaults to groestlcoin, but can be overridden with the LIGHTNINGD_NETWORK envvar.
• Developer: A new Rust library called cln-rpc can be used to interact with the JSON-RPC.
• JSON-RPC: A new msggen library allows easy generation of language bindings for the JSON-RPC from the JSON schemas.
• JSON-RPC: listchannels now includes the funding_outnum.
• JSON-RPC: coin_movement to 'external' accounts now include an 'originating_account' field.
• JSON-RPC: Add exclude option for pay command to manually exclude channels or nodes when finding a route.
• Database: Speed up loading of pending HTLCs during startup by using a partial index.

Features
• Creating channels.
• Closing channels.
• Completely managing all channel states (including the exceptional ones!).
• Performing path finding within the network, passively forwarding incoming payments.
• Sending outgoing onion-encrypted payments through the network.
• Automatic channel management (autopilot).

Important Announcements / Groestlcoin Core v23.0 Release...
Last post by jackielove4u - June 22, 2022, 08:47:57 PM
A new major Groestlcoin Core version 23.0 is now available for download, so it is recommended to upgrade to it if you are running a full Groestlcoin node or a local Groestlcoin Core wallet.


v23.0 is now the official release version of Groestlcoin Core. It is recommended to upgrade to this version as soon as possible.

What's new in version v23.0?
This is a major release of Groestlcoin Core, featuring the technical equivalent of Bitcoin Core v23.0 but with Groestlcoin specific patches.

Changelog 23.0:
https://github.com/Groestlcoin/groestlcoin/blob/23.0.0/doc/release-notes/release-notes-23.0.0.md

Important:
• There is no warranty and no party shall be made liable to you for damages. If you lose coins due to this app, no compensation will be given. Use this app solely at your own risk.
• Encrypt your wallet. This can be done by clicking the settings menu from inside the wallet. Make sure your password is secure and do not forget it.
• Make a copy your wallet.dat file as a backup and move it to a secure location:
Location Windows: Navigate to C:\Users\Username\AppData\Roaming\groestlcoin\wallet.dat (or open windows explorer and enter %appdata%\Groestlcoin\wallet.dat)
Location Mac: Finder -> Go {Hold Option] -> Library -> groestlcoin -> wallet.dat (~/Library/Application Support/groestlcoin/wallet.dat)

WARNING:
While this branch has been extensively tested to be compatible with the existing Groestlcoin v2.11.0, v2.13.3, v2.16.0, v2.16.3, v2.17.2, v2.18.2, v2.19.1, v2.21.0, v2.21.1 and 22.0.0 network there is the possibility that we missed something. ALWAYS BACKUP YOUR GROESTLCOIN WALLET BEFORE UPGRADING.

How to Upgrade?
Windows: If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
OSX: If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications. Users running macOS Catalina need to "right-click" and then choose "Open" to open the Groestlcoin Core .dmg.

Last post by jackielove4u - June 06, 2022, 05:14:21 PM
The following were tested in Linux archlinux 5.15.44-1-lts, some dependencies can be different in other distros.
If you have issues make sure:
     - HyperVM is enabled in bios (to enable 64bit in virtualbox)
     - Hyper V is uninstalled on Windows
     - Disable mcafee anti-virus, Malwarebytes and roquekiller
     - Disable sleep/hibernate mode on windows

Create a Arch VM as a building environment (it will be accessed via SSH) Follow the instructions at: https://itsfoss.com/install-arch-linux-virtualbox/

You will need an aur.archlinux.org account to publish a package. You need to have a new Public SSH key (generated below) and your public GPG key registered with your account.

Set port forwarding rule on virtualbox:
name: SSH
protocol: TCP
hostport: 22222
guest port: 22

sudo systemctl enable sshd
sudo systemctl start sshd

#Export your key (or export private key on Kleopatra):
gpg --export-secret-keys $ID > my-private-key.asc
# Copy the key to the VM. To copy the exported secret-keys you can use SFTP client on portnumber 22222
#To import the key, run:
gpg --import my-private-key.asc
#Setup a passphrase for the secret key when asked
gpg --edit-key $ID
passwd
#Enter existing passphrase then press enter twice and consider the warnings from the tool and its implications before proceeding.
