Groestlcoin 22 June 2023 release

As we forge ahead in 2023, Groestlcoin (GRS) continues to showcase its resilience and commitment to innovation, even amidst the dynamic landscape of cryptocurrency. Currently standing at #581 with a market cap of approximately $29 million, GRS is a testament to the tireless work of our dedicated team and the unwavering support of our community.

The past few months have seen the cryptocurrency industry grappling with regulatory challenges. These regulatory shifts have resulted in market turbulence and uncertainty, impacting cryptocurrencies across the board, including GRS. Crypto exchanges are strategizing to navigate this ongoing regulatory pressure, leading to discussions about potential relocation to avoid these constraints.

Despite these challenges, Groestlcoin remains steadfast in its mission to provide a secure, decentralized, and transparent cryptocurrency experience. We continue to adapt and innovate, focusing on the needs of our users and the broader crypto community. Our dedication to our core principles has guided us through these uncertain times and will continue to drive our efforts moving forward.

As we navigate the rest of 2023, we are optimistic about the future of Groestlcoin and the continued growth and development of our platform. Here's to our collective perseverance and the exciting journey ahead!

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.
