[ANN][GRS] Groestlcoin | 1st to activate Segwit & Taproot

[Ive Gone Parabolic]

Lots going on!

CoinEx has been hacked.

I check this thread regularly. (Most of us are over on Telegram)

Coinex is not a dealbreaker, u can always onboard any of the exchanges I built. Volume is ate the lowest but I think we will work that out with joint effort promoting and catering for the projects already listed in the medias and beyond. As an ambassador for my own business I tend to navigate to the places that have a high likely hood of being fraught with mentally numb dorks. And in the case with u I wasnt wrong.

Electrum-grs is a lightweight "thin client" groestlcoin wallet Android based on a client-server protocol. Its main advantages over the original Groestlcoin client include support for multi-signature wallets and not requiring the download of the entire block chain.

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.

Features
• Encrypted wallet - the file that contains your groestlcoins is protected with a password. You are protected from thieves.
• Deterministic key generation - If you lose your wallet, you can recover it from its seed. You are protected from your own mistakes.
• Instant on - the client does not download the blockchain, it requests that information from a server. No delays, always up-to-date.
• Freedom and Privacy - The server does not store user accounts. You are not tied to a particular server, and the server does not need to know you.
• No scripts - Electrum-GRS does not download any script. A compromised server cannot send you arbitrary code and steal your groestlcoins.
• No single point of failure - The server code is open source, anyone can run a server.
• Transactions are signed locally - Your private keys are not shared with the server. You do not have to trust the server with your money.
• Firewall friendly - The client does not need to open a port, it simply polls the server for updates.
• Free software - Gnu GPL v3. Anyone can audit the code.
• Written in Python - The code is short, and easy to review.
• User Friendly - Support for Groestlcoin URIs, signed URIs and Groestlcoin aliases
• No Lock-In - You can export your private keys and use them in other groestlcoin clients.
• No Downtimes - Electrum-GRS servers are decentralized and redundant. Your wallet is never down.
• Proof Checking - Electrum-GRS Wallet verifies all the transactions in your history using SPV.
• Cold Storage - Keep your private keys offline, and go online with a watching-only wallet. Sign transactions from a computer that is always offline. Broadcast them from a machine that does not have your keys.
• Multisign - Split the permission to spend your coins between several wallets using parallel BIP32 derivations and P2SH addresses ("2 of 2", "2 of 3"). Compact serialization format for unsigned or partially signed transactions, that includes the BIP32 master public key and derivation needed to sign inputs. Serialized transactions can be sent to cosigners or to cold storage using QR codes

This application is licensed under the GPL version 3. 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.

Important:
Store your secret phrase somewhere safe!
The multi-signature and non native segwit addresses starts with a "3" and not with a "F".

Core lightning: A specification compliant Lightning Network implementation in C

Core lightning is a lightweight, highly customizable and standard compliant implementation of the Lightning Network protocol.
Core lightning only works on Linux and Mac OS, and requires a locally (or remotely) running groestlcoind (version 22.0 or above) that is fully caught up with the network you're testing on.

Changelog 24.02.1
• The recover plugin can now detect dataloss and guide you through the recovery process, making emergency recoveries less stressful.
• The logic of the anchor channels has been overhauled and channel fundings and closing should now be more flexible and reliable.
• reckless, our plugin manager, now knows how to create python virtualenvs for each plugin. This allows running multiple plugins with conflicting dependencies. Furthermore it can be told an exact version or commit to install.
• CLN now has a --no-reconnect-private, which tells lightningd not to reconnect private peers. This is useful for service-providers and LSPs if the majority of peers is flaky.
• The newest version of the splicing proposal was implemented. Though experimental we encourage anyone to try it out, as it informs the specification process as well.

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).
