Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

A response to the GRS Shill cries

First of all, I think it is right to say that it wouldn’t be fair for the recent reddit to be entirely attributed to the recent 130% rise in GRS price – The price has gone a lot higher when SegWit was activated and a lot higher in the runup to the previous release announcement (22nd September) and was arguably at the ‘floor’ when it was discovered by us.
I’d like to give a little bit of a backstory on the recent discovery of GRS by a small group of people in a hope you realise this isn’t just shilling some shit-coin for a pump and dump. It was never our intention to come across as shilling and certainly not our intention to attract ‘pump and dump’ groups. We merely searched for SegWit-activated coins, and the main one that kept popping up was Groestlcoin, in posts that didn’t even mention Litecoin or Vertcoin. We thought that it was worth investigating further and decided to do some more research, and the more we found we more we realised that this was a genuine diamond amongst the rocks. 254th in market cap, first to activate SegWit, Lightning Network in full development, the list was endless – and seemingly nobody knew about it which was insanity.
In several places we saw that no marketing was done or being actively planned, and it was up to the community to market the coin if they wanted to whilst the 20+ developers keep cracking on to try and be the first to more developments.
We contacted the lead developer, ‘Jackielove4u’ and started a plan to try and market the coin, first by creating a Discord channel for discussions and then by trying to get their great features out to the world and aim for slow-and-steady growth.
In hindsight, a bit more finesse would have been better and the reddit posts got a little out-of-hand, if I didn’t know any better I would have seen GRS as a coin being shilled too on Reddit, and I have accused people of doing the same with Vertcoin in the past. So I thought I’d try to clear up some misconceptions and give one targeted response post to the cries of shilling and try to give the facts to the best of my knowledge, whilst trying to give an unbias opinion as much as I can based on my views and the views of the response that we’ve had.
PROS:
• Segwit Enabled Enabled first)
• Low-Power Mining – This is a selling point but people have said the power consumption is on-par with Vertcoin. I think the mining uses 2 rounds of Groestl algorithm hashing to make it more secure but is still very low on power consumption and hardware wear
• Lightning Network currently in development
• They have had an easy miner solution since 2015 – Although I’d be the first to admit it is a little clunky, but is openly on Git for improvements.
• 3 iOS wallets (Including a shared wallet), 11 android wallets (1x Secure BIP147, 1x Including sending GRS via SMS, 1x ability to use NFC tags as encryption keys), 11 blackberry wallets (Secure), 3 web wallets and 10 desktop wallets with varying features / designs – More to come on the differences soon.
• Over 80 electrum servers
• Working testnet
• Hosts their own block explorer
• Officially maintained by the Bitcoin Debian packaging team
• Ubuntu PPA available
• ASIC resistant, profitable CPU and GPU mining (And has an ARM miner apparently!) We’re just brushing the surface of the great tech that is being developed by the GRS developers.
CONS:
• Elephant in the room – The name. People have called it ugly, most don’t know how to pronounce it (It’s Groosel-coin). The developers are open to a rebrand pending a community vote in 2018.
• I’ve heard a few times ‘that logo looks like a cross between google and wordpress’. Again the logo is open to rebrand/redesign pending a vote (open for suggestions/examples!) but there is some significance in it. The ‘2’ in the logo is for the 2 rounds of Groestl algorithm hashing that is used.
• Obviously little or no marketing up until this point. Marketing is important (if not vital) for the success of a coin so we’re trying to spread some awareness.
• Lots of internet posts saying that it is a scam coin. From what I can see it seems to be because the coin has been ‘pumped-and-dumped’ a few times? By that logic, most coins are scam coins? The block reward dropped 6% a week when it was first launched specifically to prevent pump-and-dumps.
• Rumours of a pre-mine of 0.2% (240,000 coins) when it was first created. I haven’t gotten to the bottom of this to confirm or deny, but if it was true it seems to have been given as rewards for some early marketing (where those odd naked women pictures come from) and some early bounty rewards to get the ball rolling. No pre-mine is ideal but its personally something I can look over now if it IS true.
• Over 70% of the mined coins are owned by the top 100 addresses. Again, this is clearly an issue that many other coins also are facing (albeit some to a lesser extent). I can only guess that the more time that passes being a lesser-known coin, the greater risk that this becomes as the same miners mine for a longer period of time. Not sure if this matters much but it’s also worth noting that 24% of the mined coins appear to be on Bittrex currently.
TL:DR – Trying not to shill GRS, just trying to get the word out. Criticisms about the coin have been noted by the developers and they are very open to change and improvements suggested if they are the popular vote. I recommend that you research more into the coin, coin the discord on https://discord.gg/8VURndr and make a decision based on your own research whether you'd see something in, and like to support the coin.
Apologies for such a long post..

Groestlcoin ivendPay Integration

ivendPay and Groestlcoin cryptocurrency have announced the start of integration.
IT company ivendPay, the developer of a universal multicurrency payment module for automatic and retail trade, intends to integrate Groestlcoin cryptocurrency — one of the oldest and the most reputable Bitcoin forks into the payment system. Groestlcoin is characterized by instant transactions with almost zero commission and is optimal for mass retail trade where micropayments are mostly used.
According to Sergey Danilov, founder and CEO of ivendPay, Groestlcoin will become the 11th cryptocurrency integrated into the payment module. The first working vending machines for the sale of coffee, snacks and souvenirs, equipped with ivendPay modules, served the visitors of the CryptoEvent RIW exhibition at VDNKh in Moscow and accepted Bitcoin, Go Byte, Dash, Bitcoin Cash, Ethereum, Ethereum Classic, Zcash, Bitcoin Gold, Dogecoin and Emercoin. ivendPay terminals are designed and patented to accept payments in electronic money, cryptocurrencies and cash when connecting the corresponding cash terminal. Payment for the purchase takes a few seconds, the choice of the payment currency occurs at the time of placing the order on the screen, the payment is made by QR-code through the cryptocurrency wallet on the smartphone.
The interest in equipping vending machines with ivendPay terminals has already been shown by the companies of Malaysia and Israel, where first test networks would be installed. ivendPay compiles a waiting list for vending networks interested in buying terminals and searches for an investor to launch industrial production. According to Sergey Danilov, the universal payment terminal ivendPay for the vending machine will cost about $500. The founder of ivendPay has welcomed the appearance of Groestlcoin among integrated cryptocurrencies, as it is another step towards the realization of the basic idea of digital money - free and cross-border access to goods and services for everybody.

updating a .gs to retrieve CoinMarketCap data following their transition to new API

Hi, I have been using the following simple .gs to pull CoinMarketCap prices but it is broken now with their migration to their new API.
