Groestlcoin 22nd March Release – 10 Year Anniversary

Groestlcoin Release March 2024

As we toast to Groestlcoin’s (GRS) 10th year in 2024, let’s celebrate not just a decade of innovation but also our recent leap onto Bithumb with a KRW pairing. This moment feels like a hug from the future, promising us a spot in the bustling crypto scene of South Korea. Amidst evolving tech and shifting regulations, our journey continues, powered by our resilient spirit and your unwavering support. Here’s to us, to GRS, and to the exciting adventures that await.

🤲Help GRS Survive

This year has brought its share of challenges for Groestlcoin (GRS). The delisting from major exchanges like Binance, compounded by the bankruptcy of Bittrex due to regulatory pressures, has significantly impacted our ability to gain traction in the ever-competitive cryptocurrency market. This sequence of events has strained our financial resources, bringing us to a critical juncture in the journey of GRS.

In light of these challenges, we are reaching out to our dedicated community for support. The survival and growth of Groestlcoin now hinge on the collective effort of those who believe in its potential and future. Contributions can make a substantial difference in keeping the vision of GRS alive.

To support GRS, donations can be made in Bitcoin, Ethereum, or Groestlcoin. Every contribution, big or small, is a step towards sustaining and advancing Groestlcoin in these trying times. Here are the addresses where donations can be sent:

  • Bitcoin (BTC) Address: 362mx8pNhvy9eAyPsDYtbq5FFDBNcUFUTZ

  • Groestlcoin (GRS) Address: FWN1qdiRrymSR6jbpbanLYqZpjkEaZouHN

Your support is more than just a donation; it’s a lifeline that can help keep Groestlcoin afloat. Together, we can overcome these challenges and continue our journey towards innovation and success in the cryptocurrency space.

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.

Core lightning 24.02.1

What am I?

Core Lightning is a specification-compliant Lightning Network implementation built in C. It is a lightweight, highly customisable and standard compliant implementation of the Lightning Network protocol. Core Lightning only works on Linux and Mac OS and requires a local or remote instance of Groestlcoind (version 2.16 or above) that is fully synced to the correct blockchain.

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

  • Ability to create new channels
  • Ability to close existing channels
  • Completely manage all channel states, including exceptional ones
  • Performing path-finding within the network, passively forwarding incoming payments
  • Sending outgoing onion-encrypted payments through the network
  • Automatic channel management (auto-pilot)
