What am I?
Groestl Nodes aims to map out and compare the status of the Groestlcoin mainnet and testnet networks.

- Shows IPv6 nodes
- Supports both main net and test net
- Node Checker – Check the status of a remote node
- Ability to download node data by CSV, JSON or TXT format
- Ability to download unique address data by CSV, JSON or TXT format
- Shows last seen time for each node
- Shows uptime for each node

AGCore is an Android app designed to make it easier to run a Groestlcoin Core node on always-on Android appliances such as set-top boxes, Android TVs and repurposed tablets/phones. If you are a non-technical user of Groestlcoin and want an Android app that makes it easy to run a Groestlcoin Core node by acting as a wrapper, then AG Core is the right choice for you.

Its been a while and I have been neglecting the community here on reddit. A lot of things are new, I'll try to keep it as brief as possible.
"My client is saying something about an 'IBO' wtf is this shit? Is Blackcoin DOOMED?!"
Well, fear you not. Blackcoin is still going forward, but as Blackcoin Lore. The IBO message is relating to rat4's new project of which he is working towards. I wish him all the best on that. The #1 question that I get though, "Should I burn my BLK?" I will give a suggestion that I hope others will find fair.
Blacknet is experimental, not yet released, not yet proven, so if you are willing to risk some of your BLK to be a part of something new, then go do so. Should you expect that it gets released? To a degree, yes. Rat4 always has done well. For me personally, I hadn't burnt my BLK as I am skeptical on the distribution and community upon release. However, I do not want to deter anyone from not participating if they can afford the risks associated with new technology.
"What in the fak is going on with development? Is Blackcoin DOOMED!?"
Janko departed to work on some exclusive blockchain projects of which he had told me about. I'm excited for him and again, wish him all the best. He handed me the title of Lore to continue. Now at the time, I hadn't expected rat4 to also call it off. Lateminer and myself have taken up development under "Lore".
"What does that mean for the original wallet? Is Blackcoin DOOMED!?"
No, not at all. So this maybe a little confusing but bear with me. Rat4's client will continue as Blackcoin Lore. This is the same as how Bitcoin Core treated Bitcoin upon Satoshi's departure. There will be two identities of Blackcoin. The protocol, and the software. The protocol always and will always belong to you, the community. That will always be shaped in the way that holders of BLK will believe is best for BLK. However Lore will be under direction of us to maintain consistency.
To further confuse things, and I'm sorry, Lore previously meant Blackcoin stuff on later Bitcoin. This hasn't been a direction that I had agreed with. Sure the core is stable to that of Bitcoin, but you also share the vulnerabilities. I really do believe that the direction is going forward with rat4's old client and having BLK adapt to it's own challenges. Therefore, Lore is becoming Blackcoin "More" and rat4's client is becoming "Blackcoin Lore". Both of which will be developed by the same team. Consider More as a temporary bridge while Lore goes forward as I understand that there are some serious updates that BLK needs that More provides right now.
"I keep up to date and have known about this for the past month or so! What is really going on?"
Well, I and others need to eat and build ourselves before we can work on projects such as BLK, especially taking over development which is massive. Lateminer has been working every evening on fixing up More while I had to take a break on updating rat4's client to be more 'modern' and with it. The project shift couldn't of come at a worse time for myself as I have been trying to launch a product for my business and couldn't delegate more time than I'd like to. But, delegating time I am.
So updates on this:- Lateminer is pushing a new Blackcoin More release this week.- The new Blackcoin Lore wallet, continuation of the old wallet, has a massive new build and RPC API overhaul.- The RPC API isn't complete yet, I just need to finish it off, then we should expect a new release of BLK Lore.
Things are still happening. But thats just development, you can't focus on development and not anything else.
"Is Blackcoin going to be delisted from X? Is Blackcoin DOOMED!?"
No, likely not. We have strong ties to the best leaders in the industry of which we are currently on.
- Bittrex - The most advanced exchange in legal for the US
- CoinEgg - Chinese community exchange
- ShapeShift - Instant conversion to Blackcoin
- cryptoID - Long time friends of Blackcoin for the block explorer with a few BLK specific features
- Coinomi - The multi wallet kings from Spain
- CoinGecko - Bobby and crew from Malaysia, the best coin market cap tracker. We are planning on doing some giveaways with them shortly.
"Why no Binance?"
Well though I do see that Binance is vastly popular, we have to consider legalities of platforms. Binance doesn't have a jurisdiction of which they are lawful to. We don't know where their servers are at. Their employees are mostly private. Those raise red flags to me. That doesn't mean that I am against it. I wouldn't mind putting in a request however, I'm not ready to stick to a strict weekly update that they require until my company's project is launched and new Lore and More is out. At that point, we will update them weekly as well as provide them all information that they require on a regular basis of which we do for every other service of which we are on.
"But the ranking of BLK! WTF!?"
Yeah, I get that. Honestly, I'm not surprised. BLK really nose dived after China called it quits on crypto. 80% of our volume was there and we had the strongest ties with that community. It was devastating and heart breaking to see it collapse almost overnight. The QQ group and Wechat group is still around, still have some die hards. I'm not surprised it had happened.
"We have not heard from you where had you been!?"
Well, I had wanted to walk away from BLK a few times. Usually if there is a team taking care of the project, I feel as if I can focus more on my company. Yet, hadn't left. Mostly everyone else left, I'm still here. I have been keeping the twitter and other things going and as well as established the Proof of Stake Alliance with other projects such as PIVX, Peercoin, Komodo, Navcoin, BitBay, Particle, Phore etc. and we all keep regularly in touch almost every day.
"So what does the Proof of Stake Alliance do?"
Well, all the devs can pool resources together to make the core technology even more sound. While we believe that 3.0 is safe and doesn't have any serious flaws, we do want to improve on it. We are working on a sort of PoS 3.1 which will be basically a total overhaul of the structure of PoS instead of actually changing the security of it.
"PoS 3.1??! Sounds exciting!"
Yes, we originally were running with the name of PoS 4.0 but, since it isn't a security upgrade, but still massive, we decided not to call it that unless there actually is a reason to update the security to ensure that the coin is protected.
"I have a question!"
Leave it below.
I really don't want to let anyone down, or left feeling insecure with their choice on Blackcoin. Its been a rough few months, but we will all pull through.

Bitcoin is a cryptocurrency developed by Satoshi Nakamoto in 2009. Bitcoin is used as a digital payment system. Rather than use traditional currency (USD, YEN, EURO, etc.) individuals may trade in, or even mine Bitcoin. It is a peer-to-peer system, and transactions may take place between users directly. Bitcoin has been stagnant for a pretty long time now and many people have lost interest in it. So nodes that were once active have been shut down.
