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..
Interesting technical facts about Groestlcoin that might explain price rise
Disclaimer: After doing some research, I own a small amount of Groestlcoin and no Vertcoin (I rkn VTC is overvalued currently). Might buy some VTC after it corrects. Here's why...
Groestlcoin with a market cap of only $14,458,912 seems undervalued for now given the current Crypto market climate
Groestlcoin appears to be technologically superior, however has an unfortunate name and a lacking community (644 Reddit subscribers)
Vertcoin appears to have a larger community (13398 Reddit subscribers), has been pumped for last 11 days (up 400%) and now a Market Cap of $183,045,997
This week people seem to be more interested in ASIC resistant coins and looking towards alternatives like VTC and GRS (essentially better versions of Bitcoin Gold with experienced teams and developers)
See below for some more technical facts about GRS from jackilove4u that was posted 4 days ago.
From the GRS discord: BCG came and people discoverd that is has the same qualities as VTC But then not premined and ASIC resistent Then people started looking for more ASIC resistent coins and came to GRS VTC has a great dev team and now people are seeing that GRS has developed a lot further then VTC Then this list came with GRS First coin with SegWit Only coin that has succesfully ported Bitcoin Armory Only coin that have over 40 Electrum servers. One of the few coins that have a Ubuntu PPA available One of the few coins that is officially maintained by the Bitcoin Debian packaging team Only coin that has succesfully ported Multibit HD We have 10 different Android wallets. Most struggle to have just 1. We have 9 different Blackberry wallets. Most dont have any. One of the few coins that have an ios wallet We have over 10 different desktop wallets Only coin that has ported Samourai and thus succesfully implemented BIP147. You can work with payment channels with Groestlcoin. One of the few coins where you can play with OP_HOLD, RBF and other new features Only coin that has ported electrum client to java One of the few coins that has ported rushwallet.com Only coin with over 100 repositories with developed work. Only coin that is capable of sending GRS over SMS Only coin that has wallets which can use NFC tags as encryption key. Only coin that has ported Msigna. Only coin that has ported sentinel. Only coin that is still being compiled with Visual Studio (like Satoshi himself did) We got now also 2 ios wallets We got 1 more android and 1 more blackberry wallet We have a working testnet We got a testnet android and blackberry wallet We got a chrome os wallet We got 2 new webwallets We got tor support for our electrum since january 2017 We got 40 tor servers VTC jumped from 0.60 usd to 4usd in two weeks (my guess is partially thanks to the btc fork) GRS is now only 0.12usd And all these have SW, LN and AS TLDR: GRS is very well developed.

[IDEA] [PROPOSAL] Monero Debian (deb) packages / Debian package repository deb.getmonero.org (I can do)
I have the skills to implement this if wanted. Possible User Experience This is a proposal, i.e. not implemented yet. Instructions for users, simplified. How to install monero using apt-get Download the repository signing key. wget https://www.getmonero.org/monero.asc Add the signing key. sudo apt-key --keyring /etc/apt/trusted.gpg.d/monero.gpg add ~/monero.asc Add APT repository. echo "deb https://deb.getmonero.org buster main" | sudo tee /etc/apt/sources.list.d/monero.list Update your package lists. sudo apt-get update Install monero. sudo apt-get install monero A few technical implementation details I would simply grab the binaries provided by getmonero.org, download them, check software (gpg) signatures, put these into deb packages, add these to a repository, and upload the repository. What I would not do is creating the binaries during package creation. While this is nice to have, it doesn't help user experience and blocks the progress on reaching this goal. See next chapter. Why simply put the pre-build Monero binaries into a deb package? 1) After bitcoin existing for more than 10 years, being popular and being in Debian unstable (sid) it still never made its way into Debian testing, let alone stable. Reason being explained that a difference in underlying libraries (even just security fixes) during compilation may result in a network split. Binaries compiled during packaging on different versions of Linux distributions might have different libraries that might cause a network fork / chain split. References:
(Note: above website saying Tags: fixed-upstream is probably a mistake as discussion at bottom says.) 2) The github issue of packaging monero stalled. 3) By shipping the same binaries as provided by getmonero.org reduces the chances of introducing a backdoor. Many Options
By adding Monero to Whonix repository, a effort for creating a separate Monero repository could be saved. I.e. instead of deb https://deb.getmonero.org buster main users could do deb https://deb.whonix.org buster main. It's really just about the upload location. By providing DNS, even upload to Whonix server can offer https://deb.getmonero.org.
Either I create the build instructions and source code of this implementation (Debian package and repository creation) the long term maintenance of putting new binaries into updated packages or only create build instructions and source code and someone from Monero team could create the actual deb packages and deb repository.
gpg signed debs. Either gpg signed debs or an apt repository. Or both. Your choice.
I'd start with Debian and perhaps Ubuntu packages for 64bit. Perhaps also 32bit. Potentially I could also do packaging for Feodra based distributions.
Timeline Doable quickly. The electrum (bitcoin) AppImage was recently added to a Debian package (binaries-freedom) by me and is now easily installable in Whonix. Pre-installed in testers version of Whonix already. About Me I am the founder of Whonix, which I am maintaining at present for more than 7 years. Whonix (formerly TorBOX) is a Debian GNU/Linux–based security-focused Linux distribution. It aims to provide privacy, security and anonymity on the internet. You can see an overview of packages I am maintaining on my github profile. To proof that this forum account adrelanos corresponds the same person maintaining whonix.org, it is added here. Questions What happened to, what is the successor of the forum funding system?
I know Monero is open source and well reviewed, but the Tails guys only add software from the Debian repository which has gone under more extensive security review and compatible with Debian based software and dependencies. As you can see Monero was rejected multiple times because it's not it Debian yet:
I would really love to see Monero in the Debian repositories, not just from a security perspective, but even from a popularity perspective, since after that many thousand new users could try it out. I think the Monero development team should establish communication with the Debian team about the procedures to get added into Debian, ASAP.
Just a warning about the electrum bitcoin wallet on debian sid
I installed electrum from the repository today and when I tried to send some bitcoin I received an extremely convincing pop-up in the client with pictures and everything saying that my client was out of date and that I needed to visit the site to update. Of course the site linked was electrum.la as opposed to the official electrum.org. Luckily I noticed this pretty fast, but this is definitely one of the most advanced phishing schemes I have seen to date. The electrum package seriously needs updating, I even found a bug report about it from 3 months that hasn't been resolved. Over $3m has been stolen using this phishing scheme and that number is increasing every day. tl;dr install electrum from source on the official site, do NOT use the package right now
[META] What happened to /u/gavinandresen's expert flair?
I'm fairly sure Gavin used to have 'Expert' Flair by his name on this sub, but recently it doesn't appear. Is this a mistake, or was it a decision made by mods. If so what was the reason for it's removal? I think most would agree he's an Expert on Bitcoin - even if they don't agree with his BIP101 proposal? Criteria for being an Expert is here - https://www.reddit.com/Bitcoin/wiki/about_expert_flair
If there is ever any dispute among the experts as to whether someone should have the flair, the expert consensus on this matter will be interpreted and executed by the head admin.
I am moving back to Debian here user rights matters and nobody want to fix already fixed things. I tried to install VLC and Bitcoin core. Both hanged during install and needed to kill download process from console because there is no GUI for it - imagine this in synaptic or whatever - had no problem for many years. Then VLC could't access my second drive mounted in mnt folder ... it looks like besides normal user level rights now you have application rights ... common this is joke - ok you can add permissions to VLC. Now best part. I have bitcoin wallet on external drive and what - you cannot add permissions to snap bitcoin core to access storage devices as snap packages need to have ability to receive those rights ... installed DEB from SID - next week bye bye ubuntu.
Ethereum on ARM. Geth and Parity clients update. Status.im, IPFS and Swarm packages. Raiden Network and Trinity client installers.
EthArmbian  is a custom Linux image for the NanoPC-T4 ARM SoC  that runs Geth or Parity Ethereum clients as a boot service and automatically turns the device into a full Ethereum node. Once powered up, the image takes care of all steps, from setting up the environment to running the Ethereum client and synchronizing the blockchain. Edit: Images links are now Ready for Constantinople and Petersburg Hardforks. You can update Geth to 1.8.22 and Parity to 2.2.9 from these images by running: update-ethereum This is a new release of the EthArmbian image for the NanoPC-T4 ARM board. Ethereum is evolving quickly so it is time to include some other interesting pieces of the ecosystem. Changelog:
Ethereum clients update (Geth 1.8.21  and Parity 2.2.7 ). Swarm is now included in the Geth Debian package
Status  is a decentralized messaging & browsing app (using the Whisper protocol). And as any P2P system, it needs… peers. So if you want to support it, status is now included as a systemd service, configured in whisper and mailserver mode. You need to start it manually as it doesn’t run by default: sudo systemctl start status.im And, if you want it to get started on boot you need: sudo systemctl enable status.im Configuration options are located in /etc/ethereum/status.im.json. Why run a Status node? (from their FAQ):
Currently, we don’t provide any incentives for running Status Nodes. We are working hard to solve this problem. Our intent is to increase the size of the Whisper network, thereby improving how “decentralized” and safe our platform is. Another reason is privacy. In the current setup, nodes that are running as Mail Servers are trusted. This means that such a node can communicate directly with the Status app using a p2p connection and some metadata might leak. If one wants to avoid that, the best option is to run a Mail Server on your own and configure it in the Status app.
Another important piece of the so called web 3 is decentralized storage. The most mature option available is IPFS  which is now included as a systemd service as well. You need to start it manually as it doesn’t run for default: sudo systemctl start ipfs If you want IPFS to get started on boot you need to enable it by running: sudo systemctl enable ipfs You can tweak config options in /home/ethereum/.ipfs/config file (particularly, you may want to adjust the StorageMax parameter). Swarm  (Ethereum decentralized storage solution) is available as a binary. You may want to take a look at the official docs to start testing it. You can run these clients along with Geth or Parity client with no performance issues.
Raiden and Trinity
As you may know, Raiden Network  is a Layer 2 scalability solution (similar to Bitcoin's Lightning Network). Trinity  is a new Ethereum client developed entirely in Python (and already working on the beacon chain). You can install both clients by running its corresponding bash script. Take into account that both are in alpha stage so expect some trouble and give back feedback to developers, if possible. They are not properly packaged yet so the script installs them directly from Github (it takes a while). Installation: Type (as ethereum user): install-trinity install-raiden You can now run "trinity" or "raiden" commands. Note on Trinity: If you experience this issue: “trinity: error: Timed out waiting for database start”, try to increase wait_for_ipc() “timeout” value in /uslocal/lib/python3.6/dist-packages/trinity/utils/ipc.py 
Ethereum nodes FUD
We’ve been seeing lately a lot of misinformation about Ethereum blockchain size and other kind of FUD. Stick to the facts. With Parity, it just takes several hours to get a full node up and running and you need about 140 GB of SSD disk size (2-3 days with Geth and 150GB of disk size). So, you could run a full node for several months even with a 256GB SSD unit. Don’t listen to this kind of nonsense. Plain and simple: they are wrong. This "guy" knows 
Huge performance difference doing the blockchain sync in bitcoin core 0.17.1 vs. snap bitcoin core 0.17.0.1
Hi, I recently installed a fresh Ubuntu 18.04 and, as it was already late and I wanted to sync the blockchain overnight, quickly searched for bitcoind in the graphical package manager and to my delight there was a package 0.17.0.1 that I misread for 0.17.1, so I installed it not looking further into it and started the sync. The software immediately hogged >90% CPU usage, the fans started to run at full speed, the laptop ran hot as hell and the sync lasted like 14 hours. Next day when the sync was done I realized the f***** graphical install tool had installed a so called snap package, what's the newest craziness in Ubuntu to drive users away to other distros. Then I found out that the package is maintained by a guy who is completely unrelated to bitcoin core and a known shitcoiner, someone who can't be trusted. The guy didn't even realize he was confusing 0.17.0.1 with 0.17.1, wtf. See here for more info: https://bugs.launchpad.net/snapstore/+bug/1803914 Of course I immediately wiped the whole crap off of my installation, luckily before restoring any wallet balances. I also wiped the complete snap system, whoever came up with this shit should be tared and feathered and then be forced to use MS Windows for the rest of their life. Afterwards I installed 0.17.1 from https://bitcoincore.org/en/download/ and properly verified my download before starting the blockchain sync. There was a *huge* difference in performance, no noticeable CPU usage, no fans spinning up, and the whole sync process took maybe 4 hours, so a whopping third than the bogus snap version needed. I looked into the release notes, there is some mentioning of performance enhancements, but nothing about a reduction of sync time by two thirds. So here comes my question, anybody knows more about this dubious Ubuntu snap package? Why is there such a performance difference, is this thing a genuine bitcoind at all or has someone tampered with that thing? At least this should also be a warning to Ubuntu users, disable that snap crap and use apt to install software, and install critical stuff like bitcoin per hand from the official download page. And better use Debian and ditch Ubuntu like I will do as soon as I find time for it.
My thoughts and observations on XMR: I have been following cryptocurrencies since 2010; however I did not have the requisite computer literacy at the time to effectively understand and use them. Several years ago, I bought a small amount of Bitcoin, but did not truly pusue it. Recently, I resolved to become sufficiently computer savvy. After months of self-study, I decided to test my skills with a desktop home build, to feed my gaming addiction. A friend of mine suggested I should mine Monero while the rig was idle. I had only heard of Monero as 1 of 1000 altcoins. I was intrigued by XMR's CPU minability, something I thought no longer existed in the cryptosphere. I've been mining ever since. (My rig sports an i7-6700K CPU and dual GTX 1070's.) I started mining in December of last year. I'm a hobbyist miner, nothing more, but I can say that mining has had a psychological effect on me. I follow the story of Monero with an excitement that my Bitcoin purchase never brought me. Perhaps this is because mining is an ongoing process instead of a single accumulation event. Here is a summary of what drew me to Monero, what it has already accomplished, where I think it needs to go, and what I think some of its most special features are. As a zealous convert from Bitcoin, I can't help but think of BTC as a foil for XMR. First and foremost, I was drawn to Monero due to it's ability to be feasibly mined on both CPUs and GPUs. I like the idea of being able to put idled pieces of technology to work; old phones and computers could be utilized to mine. ASICs are expensive, closely tied to the price of the coin they mine, and provide no other utility to my life. CPUs and GPUs are a less risky investment, because they have utility and value independent of crypto mining. When I joined the Monero revolution, hardware wallets were not available yet; this means there was also an opportunity to use truly ancient tech as an air gapped wallet, allowing me to even utilize machines that were uneconomic to mine with. I have always been a sort of scrap-oriented hacker, and I take pride in mining on computers and phones that I have assembled, upgraded, or refurbished myself. This is an experience that cannot be replicated by plugging in an ASIC; one of the biggest things that drew me to Monero was the dev team's commitment to mining on consumer technology. My faith in the project was affirmed by the recent PoW change. The second major factor that drew me to Monero related to the (in my opinion) greater utility of the address format and mnemonic seed, as compared to Bitcoin. I've always felt that BTC's mnemonic seeds and HD wallets were sort of grafted on to the underlying protocol. As an example, not all HD wallet seeds are compatible; you need to be running a program (such as Electrum) that works with that seed. In Monero, the mnemonic seed was considered from the beginning, and integrated into the core client. We can carry our XMR seeds across platform without worry. If memory serves correctly, GUI seeds can be used in Monerujo and MyMonero. I've been told they work with Cakewallet as well. This a great convenience I think we often overlook. I feel like my next point is somewhat related to the above point; we do not have to hassle with xpubs. Using xpubs means you need to give out a new address every transaction, or deal with the consequences of address reuse. Monero's automatic stealth address integration not only addresses some of these drawbacks, but it also offers the convenience of only having to copy a QR code once. Your XMR address never changes, so it's a lot more convenient to have something like a donation address or pre-printed QR codes, for example. Another feature of XMR that I think sets it apart is it's tail emission; surprisingly few coins have it. Not only does a tail emission incentivizes mining indefinitely, it also replenishes the coin supply. Coins will inevitably be lost over time as people die or lose their seeds; in the long term this could result in volitility due to a lack of liquidity, which is detrimental to the whole crytpo ecosystem. I think Monero's conservative tail emission is forward thinking in that respect. Enough coins will be replaced to ensure ongoing mining as well as general liquidity. Thus far, I haven't even mentioned the privacy aspects. Ring Signatures, Ring CT, and Stealth Addresses all work together to give Monero users a great degree of privacy. These are great features that would have drawn me to hold the coin, even if they didn't pique my interest to mine it. There can still be improvements on this front, and in fact there have been and there will continue to be. Minimum Mixins have been increasing, improving plausible deniability. Subaddresses give Monero users the ability to utilize multiple receive addresses, gaining some of the advantages of BTC's xpubs. Bulletproofs are coming, increasing the efficiency of Monero's cryptography. Kovri is coming, not just for the official GUI wallet but hopefully also for mining pools as well. There have been other recent innovations as well such as multi-signature transactions which allow Monero to take advantage of escrow abilities. The ecosystem around the blockchain has grown as well, notably in the realm of hardware wallets. The use of Monero will likely soar as a result of these new augmentations. Here are some of the developments I have witnessed in my short time as a part of this community: (1) Multi-signature Support (2) Subaddress Generation (3) Hardware Wallet Support (4) Anti-ASIC PoW Change (5) Mixin Size Increase Here's what I am looking forward to as catalysts: (1) Kovri integration (2) Mobile hardware wallet support via Monerujo (3) Monero as a Debian package integrated into Tails OS (4) Bulletproof transaction size reduction Continuing PoW forks to combat ASICs (5) XMR adoption as base currency on Bisq These factors are what galvanize my belief that Monero will only increase in utility over time. XMR has lost over half it's value since I started mining, and I can't but help to see it as an opportunity. XMR is only getting steadily better than Bitcoin; parity may be closer than we think. There is only one major roadblock to adoption, in my mind, and I believe it is an inevitable consequence of our encrypted blockchain. Frankly, making a view-only wallet is a cumbersome pain. The private view key only lets you see incoming transactions, so you need to import the signed key images from another machine. This is a much more painstaking process than simply exporting a Bitcoin xpub. Thankfully, hardware wallets can be a solution to this problem, as a means of providing access to private keys and key images. Technical difficulties are quickly melting away, priming to release Monero's revolutionary potential. Monero is my dream coin, embodying what I feel are all the central tenants of the original cypherpunk cryptocurrency movement. What else are you looking forward to in the future of Monero? Does anyone else share my sense of giddyness for the future?
