Hi guys, I posted this over at BitcoinBeginners but it hasn’t received a lot of useful input. I’ve read the FAQ there and searched around the web for answers, but could really use your help. I have a dedicated 2011 MacBook Pro running High Sierra that I’d like to use in support of Bitcoin. So far, I have installed and verified GPG Suite and Bitcoin Core following instructions from bitcoin.orf. It is now synced, and I hope to add block explorer, a lightning node, and an electrum server. Once complete, I’d like to create some tutorials and guides to help others who have old Macs, since there is already a lot of good info for Windows and Linux. I found this guide on Medium talking about Power Node Launcher, but it’s doesn’t have the same emphasis on security as the other tools I’ve setup. Before taking next steps, I’d like input from the community on the order of steps and trusted sources for installing the aforementioned programs. If there is anything else I can do with my computer and bandwidth to help Bitcoin, please let me know. Specifically, if I am able to setup a lightning node, would it help if I stored some bitcoin on it to support transactions? Should I setup a slow simple mining program or run an older ASIC miner that is not part of a pool just to help diversify the network? Should I setup a satellite connection as Andreas suggested in one of his older videos? Thanks for your input.
New England New England 6 States Songs: https://www.reddit.com/newengland/comments/er8wxd/new_england_6_states_songs/ NewEnglandcoin Symbol: NENG NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones. Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt. 1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377 NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number Bitcoin Fork - Suitable for Home Hobbyists NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs. The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

Users can easily set up full node for mining at Home PC or Mac using our dedicated cheetah software. Research on the first forked 50 blocks on v1.2.0 core confirmed that ASIC/GPU miners mined 66% of 50 blocks, CPU miners mined the remaining 34%. NENG v1.4.0 release enabled CPU mining inside android phones.

There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG. We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

Therefore, along with the big update (which includes the release of the game Stairs, Stairs Profit Competition, adding of BTC and BTT) we are updating the distribution system of the dividend pool.What will change?For the stable operation of dividend payments, the BetFury team decided to replenish the dividend pool in the amount of 3,500,000 TRX. Dividend payments will be 3%. Thus, payouts per 100K BFG will become larger and more stable.Distribution example:
The previous pool size was2,300,000 TRX*. With* 7%payout, the distribution will be161,000 TRX (16.9 TRX per 100,000 BFG daily).We add3 500 000 TRXto the pool (= 5 800 000 TRX) with the payout of3%, the distribution will be equal to174 000 TRX (16.9 TRX per 100 000 BFG daily)
Also, the BetFury team recharged USDT & BTT pool in the amount of 4000 USDT/3 000 000 BTT respectively. The advantage of such a dividend policy BetFury will stable payments and increase investment interest to the platform.

Quantum Resistant Ledger(QRL）is a blockchain network which is designed to resist quantum attacks. The founder of QRL, Peter Waterland is one of the earliest group of people who have worryies about the safty of Bitcoin, Etherreum and other blockchain network which use ECDSA or similar algorithums. With the developement of the quantum computing technologies, the encryption algorithums of these cryptocurrencies will have no effect someday in the future for sure. QRL figured out a way to slove this problem, it uses a hash-based eXtended Merkle Tree Signature Scheme (XMSS) to encrypt the message. To make a long story short, QRL utilitize the cryptographic method with minimum security requreiment that rely only upon on the collision resistance of cryptographic hash function. the hash-based digital signature scheme is generated from such function. Such signartue is called one time signatures(OTS), which could only be safely used for one time in encrypt the message, so for each address QRL use many OTS which is generated by a binary hash tree, also know as Merkle Tree. QRL is programmed with python and The total amount of QRL token is 105,000,000. Now the QRL ranked No. 62 in miningpoolstatus.stream. It also allows developers to easily build applications on its platform.

Let me start this off with this is NOT a comprehensive, end-all-be-all guide to 'how to setup a livestream.' This is simply the workflow/setup I've come to use over 4 years of on and off streaming on Twitch. Hopefully it can help some of yall out that are (finally XD) joining the livestream world. *I only stream on Twitch using OBS, so this will be specific to Twitch and OBS; I have not tried YouTube, Facebook, Instagram, or any other platform or streaming software, but the basic outline is kind of there. Hardware: 2x 1200's, Rane TTM57sl mixer with Serato Scratch Live, Samsung laptop, Behringer Xenyx 802 USB mixer, Shure SM57 mic, Pansonic GH2 or Logitech webcam (depends on if I'm using green screen or not), and then my gaming PC is my streaming PC. For speakers, I have a Yahama receiver running a 5.1 system that I use with my gaming/streaming PC. It's not the best setup for DJ'ing necessarily, as the receiver can add quite a bit of latency, but if there is any now, I barely notice it. I run the receiver in 5 channel stereo, and turn off any signal processing that I can. Audio setup: I run 1/4" out of the booth outputs on the TTM57 into the Behringer mixer (this is for the stream audio). Then I have RCA -> 1/8" from the aux out on the TTM57 into the aux input on my receiver for my 'monitors.' I run the mic (XLR) into the Behringer mixer as well. The Behringer connects via USB to my stream PC. Camera setup: I either use an HDMI to USB3.0 capture card with my GH2 or a Logitech USB webcam. All it takes is plugging it into the stream PC. Easy enough. OBS setup: There are a TON of YouTube and written tutorials to setup OBS, but they generally focus on gaming and not so much DJ'ing. I won't go into too much detail, but will point out stuff more particular for DJ'ing. This is my main OBS screen. Have everything plugged in and turned on before you open OBS to make sure it picks up your USB devices (USB mixer and camera). Should go without saying, but also make sure you have your drivers installed for the devices. [Imgur](https://i.imgur.com/b2zJazj.png) The only audio I want outputting to the stream is from the Behringer mixer, so the desktop audio and camera audio are muted. Aside from the camera and mixer, all of the other sources in my source window are optional. (If you're curious as to why Winamp is in there, I can add details on that in a later post) Output settings: [Imgur](https://i.imgur.com/p2mIfvC.png) Video bitrate will depend on your ISP, your upload speed, and your streaming PC hardware. I've had to drop mine down to 2500kbps from my usual 3500kbps recently. I guess with everyone at home using the interwebs, my connection seems a lot more unstable than even a month ago. I set the audio bitrate to 320kbps, but I think Twitch ends up compressing it to 192kbps for viewers. Recording settings are optional, I only recommend streaming and recording at the same time if you have a decently powerful streaming computer. Better to record just the audio in your DJ software to upload the mix later. Twitch will mute any replays with copywritten material, so I upload to Mixcloud for archiving. I run the mic through the Behringer mixer versus the mic input on my Rane mixer because I talk to chat, and it's annoying listening back to mixes with me yammering through parts. My GPU recently kicked the bucket (still works on default Windows drivers...which has caused some bottlenecks when it comes to streaming, but I can still do it) so for now I'm using software encoding, but if you have the option for hardware encoding, use it. Video Settings [Imgur](https://i.imgur.com/2AjjHnL.png) Leave your base canvas at 1920x1080, but you want your output at 1280x720. I haven't really noticed a difference in the various downscale filters, but bicubic is what I use. 30fps is best for your viewers, as it's less demanding than running 60fps, but that's really up to you. Twitch: Twitch takes some getting used to; whether it's the website itself or the community/culture. The music community is very welcoming (especially now), and I encounter far less trolls there than in gaming channels. There's a lot of people there now trying to figure everything out, so don't feel like you're late to the party. If you want to try to make some money, you'll want to setup a donation site. Can be a simple PayPal link, Bitcoin link, or you can use something like streamelements or streamlabs. Those two extensions add other things like chatbots, commands (ie: a viewer can type !mixcloud in my chat will send a message in chat with my Mixcloud link), followesubscribedonator notifications. All of those are customizable, but I'd recommend just using the default stuff before making custom notifications and such. It can be a bit of a time sink..but then again I guess we got nothing but time right now. After you get up and going with a few streams, set your sights on reaching affilate. It's not that difficult to get, nor do you lose it if you don't keep up with the requirements to get it. You can then make custom channel emotes (again, another time sink, or there are a ton of artists out there that can make them for you) and accept subscriptions and bits. Twitch is owned by Amazon, so if you're a Prime member, link your Amazon account and you get a free subscription you can give to one streamer per month. It doesn't auto renew, so you can change it every month, but it is a nice 'gift' to give to streamers to help support them. Dark Sith Lord Bezos does take 50% of the $5/month cost of a base subscription (whether a Prime sub or paid for), so if you really want to help a streamer, use donations. But if you already have Prime, may as well throw the free sub around to someone. At the end of your stream, you can 'raid' another streamer. All it is is taking your viewers and dumping them into the channel of another streamer. I generally try to find other DJ's that are playing the same/similar genre that I think my viewers would stick around for; or just other DJ's I like. Then there's 'hosting.' That is when you are offline, but your channel is playing another stream. There are auto-host settings so that you don't have to manually host channels while you're offline. Between being raided (it's pretty much random and up to other streamers; don't beg) and raiding others, it's kind of the best way to get your channel out and exposed. But, don't make it about view counts or followers. Do it because you want to mix, no other reason. The music section has all of a sudden been saturated by DJ's/record labels due to the pandemic; there's a lot of people new to Twitch who don't know there's a bunch of other DJ's in the music category, so just keep going and you'll find an audience. Other thoughts: I love streaming on Twitch. I've done several 6+ hour streams in my time there. If you come from only playing out live, it's a big adjustment. There's no crowd energy to work off of; sometimes chat can give that to you, but it can be hard when you're just in your room by yourself. I personally find it hard to mix heavieharder stuff for more than 30-45 minutes at a time, so a lot of my mixes have been more chill and kind of downtempo as I can stay in that vibe for longer periods. I've met a lot of really awesome DJ's in my time there, and it's great seeing so many more looking for a creative outlet now that we're on global quarantine. Hopefully after some semblance of normality is restored, people will continue to livestream and the viewers keep coming back. I know this has been a giant wall of text, so apologies, but hopefully it gives someone something to go off of. Let me know if anyone has any specific questions or needs clarification on anything. Happy streaming!
Welcome All to the GPUMining Crash Course! With the increase in prices in cryptocurrency, a lot of people are getting back into mining and a lot of people are brand new to the concept overall. So, I quickly wrote this crash course to help you understand what to expect and how to successfully mine your first cryptocurrency. This crash course isn't gonna have all of the fluff you'd see in a normal publication. This is just everything you need to know to get up and running on your first cryptocurrency mining rig.
What is cryptocurrency mining?
One of the main things about cryptocurrencies is that they are "decentralized". Sounds great, but WTF does that even mean? Well, the easiest way to explain it is... You know how if you want to send your friend/family money digitally, you can do so through your bank. Your bank likely takes a transaction fee and in a few days they will transfer the money. Since cryptocurrencies are decentralized, they don't have a bank or organization to fulfill the transfer of money. Instead, they outsource the computing power of their cryptocurrency network to miners (soon to be you). These miners are verifying transactions, securing the blockchain, and powering the cryptocurrency's specific network among other things. As an incentive, the miners collect transaction fees on the transactions that they verify and collect block rewards while new currency is still being introduced into the ecosystem.
What kind of rig should I build?
You can mine cryptocurrencies using your CPU, GPU, FPGA, or ASIC, but this is a GPU Mining subreddit, so I will cater this to GPUs. For building a great all-around GPU rig, there are two models of GPUs that I'd recommend:
Both of these GPUs have solid hashrates across most mining algorithms and for a decent price! You should be able to find both of these kinds of GPUs used for around $200-$250 each, which is a great price if you know what happened during the last mining craze! ($200 GPUs were out of stock everywhere and people were reselling them for $600+ each) There are also plenty of great AMD GPUs for mining, but I've worked mostly with Nvidia so that's why both of my recommendations are Nvidia and not AMD. Other parts to your rig that you'll need are listed below. Most of these can be pieces of crap and are just needed to make the rig actually run, but the one spot you DON'T want to cheap out on is the power supply unit. A decent power supply unit will keep your home from burning down while also keeping your rigs up and running smoothly. Here are my recommendations:
Motherboard - This Motherboard can hold up to 6 GPUs (considered a full rig) with the use of risers. It is decently priced and will fit nearly any mining rig upgrades that you make in the future.
CPU - You really just need the most basic CPU you can find, it's not very essential to mining unless you're CPU mining, but even then... CPU mining isn't very profitable for how expensive CPUs can be.
RAM - All you really need is about 4GB to keep this thing running. If you want more, go for it, but it's not neccessary in most cases.
Power Switch - Doesn't need to be fancy, just needs to turn the thing on and off
PowerSupply - Don't cheap out here! Pay for a quality PSU and save yourself the headache and be safe with a solid PSU. Get a GOLD quality PSU at a MINIMUM! Platinum is good too, but probably unnecessary. The linked 1300w PSU will support most 6 GPU rigs, if you're going for higher tier GPUs like a 1080ti and above or if you're having more than 6 GPUs on a single rig then you'll need something stronger.
GPU Risers - I use this kind. They work and they're not shitty. They do require 6pin for power. Use a Molex converter if needed, but going 6pin directly from your PSU is best. Your 8+6pin will probably be a little bit short, so you'll need some 6pin extenders. EVGA will sell them you for a few bucks each, but you have to call as they're not listed on the site. DON'T YOU DARE THINK OF USING A SATA CONNECTION UNLESS YOU WANT YOUR ENTIRE MINING OPERATION TO BURN DOWN AND TAKE EVERYTHING ELSE WITH IT! SATA IS NOT RATED FOR THE POWER THAT YOU NEED!!!!
Kilowatt Meter - So that you can monitor your power consumption from the wall (much more accurate than trying to calculate each piece of hardware individually). Also helps when overclocking for a higher efficiency.
120GB Solid State Drive - SSDs are pretty damn cheap now. Just get it instead of your prehistoric HDD. Also, make sure you get AT LEAST 120GB! Many of the popular cryptocurrencies like BEAM and GRIN will demand quite a bit of virtual memory, so you'll need the extra space on your SSD to compensate for that.
Something to put your rig on - This one seems to be popular, but pretty much anything will do. I literally used a shoe rack and zip ties. You just need something that will give the GPUs airflow to breathe and keep the rig organized as a whole.
Windows 10/Linux Operating System - Pretty self explanatory here. Don't go with any of the MAC OS or Apple Products. They're extremely over priced and nearly useless in the mining world.
She's built, now what?
Now you need to do a few things. I am a Windows miner, so I will be speaking to Windows here:
Update Windows - Do all of the updates. Just do it.
Update Drivers - Go to the EVGA website and download GeForce experience. It will keep your GPU drivers up to date.
Go to Windows Device Manager and make sure all of your GPUs show up under "Display Adapters". If it is there, but it isn't showing the Name/Model of the GPU as the name, right click it and select "Update Driver". This should fix it.
Assuming you've done all of this, you're ready to download a mining application.
There are tons to choose from! Claymore, Phoenix, EWBF, LolMiner, etc... It can be overwhelming pretty quickly since they all have different algorithm support, speeds, efficiencies, and a whole lot more. On top of that, in order to get them running you need to set up batch files to call the proper exe, point you to the correct pool, and a whole bunch of other stuff that can be confusing to a new user. Not to mention, you will probably need a separate miner, config file, batch file, etc. for each different algorithm that you're interested in mining on. Instead, I recommend that you download a miner management software that will take care of most of this tedious work for you. There are a few in the sidebar, but the /GPUMining favorite is AIOMiner. It was developed by our very own community member, xixspiderxix with the intention of making mining as easy as possible to do and without any fees. It supports over 100 different algorithms, so you'll be able to mine nearly ANY cryptocurrency you'd like. Just download it from their website and it will take you through a quick tutorial to help you get set up! You can also connect your rig to their website for remote monitoring and control. You've probably seen a few of their posts around this subreddit. Other Windows mining softwares include:
many more you can find from google searching
Note: Many mining softwares have fees built into them. Most are around 1%, but can go as high as 5% or greater! You want a mining software with little or no fees at all so that you get to keep as much cryptocurrency as possible. These fees aren't something you actively pay, the software will automatically take it by mining on the developers behalf for a given amount of time and then switching back to mining on your own behalf. So, please be diligent in the software that you evaluate and make sure it is reputable.
I keep hearing about NiceHash. What is that?
The asshole of the mining industry. Jk, but not really. NiceHash is a software program that allows you to sell your rig's hashing power to someone on their marketplace. They market themselves as profitable mining, but you're not really mining. You're selling your power in exchange for Bitcoin. They did a great job telling people that with them, you're always mining the most profitable coin, but that's just not true. Since it is a mining marketplace, they make you mine whatever their most expensive contract is. If their contracts are below market prices, then you're not operating as efficiently and profitably as you could be. NiceHash also has a sketchy history, which continues to this day. In 2017, they were hacked and lost $65M worth of Bitcoin. No one got paid out for MONTHS and many of their executives conveniently resigned. Their platform is also used to destroy cryptocurrencies. Since people are able to purchase mining power on their platform, people have used their platform to purchase enough mining power to control individual cryptocurrencies and duplicate coins, which increased the malicious user's wealth while completely destroying the integrity of the coin's blockchain. HoriZEN (formerly ZenCash), Ethereum Classic, and many other great cryptocurrencies have been the victim of NiceHash's platform. For this and many other reasons, we highly recommend that you stay AWAY from Nicehash. We understand that it is extremely easy to use and you get paid in bitcoin, but they are destroying the industry with their greed and lack of motivation to change their platform for the protection of cryptocurrencies.
This is pretty much everything you need to know to get started. We covered the hardware, setting up the software, which software to use, and AIOMiner's tutorial will get you up to speed on how to actually mine the cryptocurrency that you want better than I can explain it, so I'll leave that part to them. If you have any questions on this crash course, please leave a comment below where myself and other community members will be able to help you out.

The importance of being mindful of security at all times - nearly everyone is one breach away from total disaster
This is a long one - TL;DR at the end!
If you haven't heard yet: BlankMediaGames, makers of Town of Salem, have been breached which resulted in almost 8 million accounts being leaked. For most people, the first reaction is "lol so what it's just a game, why should I really care?" and that is the wrong way to look at it. I'd like to explain why everyone should always care whenever they are part of a breach. I'd also like to talk about some ways game developers - whether they work solo or on a team - can take easy steps to help protect themselves and their customers/players. First I'd like to state that there is no practical way to achieve 100% solid security to guarantee you'll never be breached or part of a breach. The goal here will be to get as close as possible, or comfortable, so that you can rest easy knowing you can deal with problems when they occur (not if, when).
Why You Should Care About Breaches
The sad reality is most people re-use the same password everywhere. Your email account, your bank account, your steam account, your reddit account, random forums and game websites - you get the idea. If you haven't pieced it together yet the implication is that if anyone gets your one password you use everywhere, it's game over for you - they now own all of your accounts (whether or not they know it yet). Keep in mind that your email account is basically the holy grail of passwords to have. Most websites handle password changes/resets through your email; thus anyone who can login to your email account can get access to pretty much any of your accounts anywhere. Game over, you lose.
But wait, why would anyone want to use my password? I'm nobody!
It doesn't matter, the bad guys sell this information to other bad guys. Bots are used to make as much use of these passwords as possible. If they can get into your bank they might try money transfers. If they get into your Amazon account they might spin up $80,000 worth of servers to mine Bitcoin (or whatever coin is popular at the time). They don't care who you are; it's all automated. By the way, according to this post (which looks believable enough to be real) this is pretty much how they got into the BMG servers initially. They checked for usernames/emails of admins on the BMG website(s) in previous breach dumps (of which there are many) and found at least one that used the same password on other sites - for their admin account! If you want to see how many of your accounts are already breached check out Have I Been Pwned - I recommend registering all of your email addresses as well so you get notified of future breaches. This is how I found out about the Town of Salem breach, myself.
How You Can Protect Yourself
Before I go into all the steps you can (and should) take to protect yourself I should note that security is in a constant tug of war with convenience. What this means is that the more security measures you apply the more inconvenienced you become for many tasks. It's up to you to decide how much is too much either way. First of all I strongly recommend registering your email(s) on https://haveibeenpwned.com/ - this is especially important if your email address is associated to important things like AWS, Steam developer account, bank accounts, social media, etc. You want to know ASAP when an account of yours is compromised so you can take steps to prevent or undo damage. Note that the bad guys have a head start on this!
You probably need to have better password hygiene. If you don't already, you need to make sure every account you have uses a different, unique, secure password. You should change these passwords at least once a year. Depending on how many accounts you have and how good your memory is, this is your first big security vs convenience trade-off battle. That's easily solved, though, by using a password manager. You can find a list of password managers on Wikipedia here or you can search around for some comparison articles. Some notable choices to consider:
1Password - recommend by Troy Hunt, creator of Have I Been Pwned
LastPass - I use this at work and it's generally good
BitWarden - free and open source! I use this at home and in some ways it's better than LastPass
KeePass (and forks) - free, open source, and totally offline; if you don't trust "the cloud" you can trade away some more convenience in exchange for taking full responsibility of your password security (and backups)
Regardless of which one you choose, any of them is 100x better than not using one at all.
The problem with all these passwords is that someone can still use them if they are found in a breach. Your passwords are only as strong as the website you use them on. In the case of the BMG breach mentioned above - all passwords were stored in an ancient format which has been insecure for years. It's likely that every single password in the breach can be reversed/cracked, or already have been. The next step you need to take is to make it harder for someone else to login with your password. This is done using Multi-Factor Authentication (or Two-Factor Authentication). Unfortunately not every website/service supports MFA/2FA, but you should still use it on every single one that does support it. You can check which sites support MFA/2FA here or dig around in account options on any particular site. You should setup MFA/2FA on your email account ASAP! If it's not supported, you need to switch to a provider that does support it. This is more important than your bank account! All of the big email providers support it: GMail, Outlook.com, Yahoo Mail, etc. The type of MFA/2FA you use depends on what is supported by each site/service, but there is a common approach that is compatible on many of them. Most of them involve phone apps because a phone is the most common and convenient "thing you have" that bad guys (or anyone, really) can't access easily. Time-based One-time Password or TOTP is probably the most commonly used method because it's easy to implement and can be used with many different apps. Google Authenticator was the first popular one, but it has some limitations which continue the security vs convenience battle - namely that getting a new phone is a super huge chore (no backup/restore option - you have to disable and setup each site all over again). Many alternatives support cloud backup which is really convenient, though obviously less secure by some measure. Notable choices to consider:
Authy - probably the first big/popular one after Google Authenticator came out (I think) - NOTE: They let you use it on your desktop/browser, too, but this is TOO much convenience! Don't fall for that trap.
LastPass Authenticator - conveniently links up with a LastPass account, some sites support extra features (like not needing to type a code, just answer a phone notification)
Yubikey - A real physical MFA device! Some models are compatible with phones, too.
Duo - this one is more geared towards enterprise, but they have a free option
Some sites/services use their own app, like Blizzard (battle.net) and Steam, and don't allow you to use other ones. You will probably have a few apps on your phone when all your accounts are setup, but it's worth it. You'll definitely want to enable it on your password manager as well if you chose a cloud-based one. Don't forget to save backup codes in an actual secure location! If you lose your backup codes and your auth app/physical key you will be locked out of accounts. It's really not fun recovering in that situation. Most recommendations are to print them and put in a fireproof safe, but using some other secure encrypted storage is fine. There is such a thing as bad MFA/2FA! However, anything is at least better than nothing. A lot of places still use SMS (text messaging) or e-mail for their MFA/2FA implementation. The e-mail one has the most obvious flaw: If someone gets into your email account they have defeated that security measure. The SMS flaws are less obvious and much less likely to affect you, but still a risk: SMS is trivial to intercept (capture data over the air (literally), clone your SIM card data, and some other methods). Still, if you're not a person of interest already, it's still better than nothing.
What Does This Have To Do With GameDev?
Yeah, I do know which subreddit I'm posting in! Here's the section that gets more into things specific to game development (or software development in general).
Secure Your Code
Securing your code actually has multiple meanings here: Securing access to your code, and ensuring your code itself is secure against exploitation. Let's start with access since that's the easier topic to cover! If you're not already using some form of Source Control Management (SCM) you really need to get on board! I'm not going to go in depth on that as it's a whole other topic to itself, but I'll assume you are using Git or Mercurial (hg) already and hosting it on one of these sites (or a similar one):
First, ensure that you have locked down who can access this code already. If you are using private repositories you need to make sure that the only people who have access are the people who need access (i.e. yourself and your team). Second, everyone should have strong passwords and MFA/2FA enabled on their accounts. If 1 person on the team does not follow good security practices it puts your whole project at risk! So make sure everyone on the team is following along. You can also look into tools to do some auditing and even automate it so that if anyone's account becomes less secure over time (say they turned off MFA one day) they would automatically lose their access. Additionally you should never commit secrets (passwords, API keys, tokens, social security numbers, etc) to your code repository. Probably 90% of cases where people have their AWS/Google Cloud/Azure accounts compromised and racking up huge bills for bitcoin mining is due to having their passwords/keys stored in their git repo. They either accidentally made it public or someone got access to the private repo through a compromised account. Never store sensitive information in your code repository! Next topic: Securing your code from vulnerabilities. This one is harder to talk about for game dev as most engines/frameworks are not as susceptible (for lack of a better word) to these situations as others. In a nutshell, you need to keep track of the following:
Is my code doing anything "dangerous"? (system-level stuff, memory access, saving passwords anywhere)
Could someone get the keys to the kingdom (API key, server password, etc) by just opening Cheat Engine and looking at memory values? Or doing a strings/hex edit/decompile/etc on my game executable?
Am I using outdated libraries/framework/engine? Do they have any known security bugs?
Secure Your Computer
I'm not going to go in depth on this one because at this point everyone should have a handle on this; if not there are limitless articles, blogs, and videos about the how/what/why. In summary: Keep everything updated, and don't open suspicious links.
Lock your computer when idle - use a password (or PIN or face unlock or whatever your OS uses) - no one should ever be able to walk up to your computer and use it if you're not looking, nor should they be able to get in if they grabbed your closed laptop off the table at starbucks (thanks u/3tt07kjt for reminding me of this one)
Use full disk encryption (especially on laptops)
Update your OS for security updates ASAP
Use anti-virus (yes, Windows Defender is fine) and keep it updated
Update your web browser ALWAYS (this is your 99% chance attack vector, so don't postpone it!)
Don't install browser extensions that you don't need - a LOT of extensions are either malware from the start or become malware later (my favorite emoji extension started mining bitcoins, FFS!) - check reviews regularly after extensions update
DO use adblock and privacy extensions - ads are a common attack vector - I recommend uBlock Origin and Privacy Badger at a minimum (note that some legit sites can break and so you'll have to fiddle with settings or whitelist)
Don't open suspicious or unknown links on e-mail, social media, discord, etc (be sure to hover over the links in this post before clicking them)
Don't open attachments, ever - unless you were expecting it from that person at that time
Don't fill out ANY forms (comments, login, registration, etc) on websites that don't have HTTPS (secure) connection - your browser will show this in the address bar, usually
In general, be suspicious of everything that comes from people you don't know - and even from people you do know if it was unexpected
E-Mail is (probably) the least secure form of communications ever invented - so try not to use it for sensitive things
Secure Your Website
I will have to add more to this later probably, but again there are tons of good articles, blogs, and videos on these topics. Hopefully the information in this section is enough to get you on the right track - if not feel free to ask for more info. Lots of guides can be found on Digital Ocean's site and they are relevant even if you don't use DO for your servers.
Use HTTPS (SSL/TLS) secure connections - it's FREE and EASY thanks to Let's Encrypt
KEEP EVERYTHING UPDATED - automate as much as you can
If you have control over the server, you MUST update the OS, the web server, and any backend application servers/languages/frameworks involved. Equifax breach was due to having out of date server software. BMG breach was worsened by having out of date server software. YOU MUST STAY UPDATED, ALWAYS
Don't store sensitive personal information - it's a huge pain to be PCI compliant, it's a huge fine if you mess it up - avoid storing any customer information that you don't actually need (see also: GDPR )
Do not allow access to SSH/Remote desktop/Database services from the whole world; the general public should only ever be able to reach ports 80 and 443 on your web server (and 80 should permanently redirect to HTTPS)
Use SSH keys instead of passwords on Linux servers
Don't run your own email server - it's just not worth it; use google apps for business, office 365, zoho, or something else for business email
Secure your domain registrar account! Don't lose your domain to a bad password or lack of MFA/2FA or an old email address! If your registrar doesn't support actual security then transfer to one that does. (namecheap, namesilo, google domains, amazon aws route53, even godaddy, the absolutely worst web company, has good security options)
A lot of this will apply to your game servers as well - really any kind of server you expect to setup.
That's it, for now
I ran out of steam while typing this all up after a couple hours, but I may revisit it later to add more info. Feel free to ask any questions about any of these topics and I'll do my best to answer them all.
TL;DR (y u words so much??)
Use a password manager so you can have different, random, secure passwords on every account on every website/service/game
Use MFA/2FA on every account, if possible
Lock your computer when idle/away
Use full disk encryption on laptops
Update your operating system (we all hate Windows Update, but it really is for our own good)
Use anti-virus (Windows Defender is fine)
Update your browser
Use good adblockeprivacy blocker browsers extensions
Don't use browser extensions that you don't really need (they could be a trojan horse of bitcoin mining later)
Don't trust anything sent by anyone, unless you were expecting it and know it's safe
E-mail is the least secure form of communications in use these days; don't trust it for sensitive things
Use source control for your game code (git, mercurial, etc)
Lock down access to your source code
Don't put secrets (passwords, API keys/tokens, social security numbers, credit card numbers) in your code repository
Don't do dumb things like store your AWS keys in your game for players to just find with simple tools
Check your code dependencies for security bugs, update them when needed
Use HTTPS on your website
Update your web server OS and software
Use secure password storage (don't reinvent this wheel, it's been solved by way smarter people)
Use SSH keys instead of passwords for Linux servers
Use a firewall to block the world from getting in with SSH/Remote desktop/database direct connections
Only allow your own IP address (which can change!) into the server for admin tasks
Don't run your own email server, let someone who knows what they are doing handle that for you
Secure your domain registrar account, keep email address up to date
... in general... in general... in general... I sure wrote those 2 words a lot.
Why Should I Trust This Post?
Hopefully I have provided enough information and good links in this post that you can trust the contents to be accurate (or mostly accurate). There is certainly enough information to do some searches on your own to find out how right or wrong I might be about these things. If you want my appeal to authority answer: I've been working at a major (network/computer) security company for almost 7 years as a software developer, and I've had to put up with pretty much every inconvenience brought on by security. I've also witnessed the aftermath of nearly every type of security failure covered in this post, via customers and the industry at large. None of the links I used are related to my employer or its products. Edit: Fixed some typos and added some more links More edit: added a few more points and links
With the large number of new readers coming to this sub we need to make information easy to access so those readers can make informed decisions. We all know there is an unusually large amount of Fear, Uncertainty and Doubt (FUD) surrounding EOS. Frankly, when clear evidence is provided it’s not that difficult to see EOS for the extremely valuable project it is. This post hopes to begin to put an end to all the misinformation by doing the following:
Giving a clear and concise answer to the most frequently asked questions in regards to EOS.
Giving a more in-depth answer for those who want to read more.
Allowing readers to make informed decisions by making credible information easy to access.
As EOS climbs the ranks we need to recognise there are going to be a lot of skeptical readers coming over and posting their questions. Sometimes they will be irrational, hostile and often just looking for a reaction. We should make it our responsibility to welcome everyone and refrain from responding emotionally to provocative posts, instead providing factual and rational answers. I will add to this post as and when I can, if you have any ideas or spot any mistakes let me know and I'll get them fixed ASAP. Im planning to add a bit on the team, centralisation and DPOS, governance and EOS VC shortly but please let me hear your suggestions!
1. How do you registeclaim your EOS tokens before June 2018?
Select Metamask, MyEtherWallet, or Ethereum Wallet
Follow the guide.
Remember that the reason you need to register your Ethereum ERC-20 address is to include your EOS tokens in order for the balance of your EOS Tokens to be included in the Snapshot if a Snapshot is created, you must register your Ethereum address with an EOS public key. The EOS snapshot will take place prior to the 1 June 2018. After this point your ERC-20 EOS tokens will be frozen. And you will be issued EOS tokens on the EOS blockchain.
So PLEASE REGISTER your Ethereum address NOW, don't forget about it, or plan on doing it some time in the near future.
There are a lot of submissions about this in /eos, so rather than making a new one please reply to this thread with any questions you may have. Don't forget to join the EOS mailing list: https://eos.io/#subscribe and join the EOS community on your platform(s) of choice: Telegram, Discord and/or Facebook. And remember, if anyone instructs you to transfer ETH to an EOS contract address that doesn't match the address found on https://eos.io you are being scammed.
2. How will the token the ERC-20 EOS tokens be transferred to the native blockchain?
There isn't one! Read the long answer then read it again, registering your Ethereum wallet is mandatory!
Within 23 hours after the end of the final period on June 1, 2018 at 22:59:59 UTC, all EOS Tokens will become fixed (ie. frozen) and will become non-transferrable on the Ethereum blockchain. In order to ensure your tokens are transferred over to the native blockchain you must register your Ethereum address with an EOS public key, if you do not you will lose all your tokens! I am not going to link any tutorials as there are many that can be found by searching Google and YouTube. block.one is helping with the development of snapshot software that can be used to capture the EOS token balance and registered EOS public key of wallets on the Ethereum blockchain. It is then down to the community to create the snapshot. This snapshot can be used when generating a genesis block for a blockchain implementing eos.io software. block.one will not be launching EOS blockchains or operating any of their nodes.
Exchange Support Some exchanges have announced that they will support the token swap. Although using this method will undoubtedly be much simpler than registering the tokens yourself it also comes with its pitfalls.
It is highly likely there are going to be multiple networks running on the eos.io software that use the snapshot. It is highly unlikely that exchanges will support them all.
It is highly likely that exchanges will not support airdrops that use the snapshot.
Exchanges that have announced support for the token swap include:
EOS.IO software is aiming to provide a decentralized operating system which can support thousands of industrial scale DApps by enabling vertical and horizontal scaling.
EOS.IO is software that introduces a blockchain architecture designed to enable vertical and horizontal scaling of decentralized applications. This is achieved through an operating system-like construct upon which applications can be built. The software provides accounts, authentication, databases, asynchronous communication and the scheduling of applications across multiple CPU cores and/or clusters. The resulting technology is a blockchain architecture that has the potential to scale to millions of transactions per second, eliminates user fees and allows for quick and easy deployment of decentralized applications.

6. Which consensus mechanism does EOS use and what are Block Producers?
Delegated Proof of Stake (DPOS) with Byzantine Fault Tolerance. Block Producers (BPs) produce the blocks of the blockchain and are elected by token holders that vote for them. BPs will earn block rewards for their service, these block rewards come in the form of EOS tokens produced by token inflation.
“EOS.IO software utilizes the only known decentralized consensus algorithm proven capable of meeting the performance requirements of applications on the blockchain, Delegated Proof of Stake (DPOS). Under this algorithm, those who hold tokens on a blockchain adopting the EOS.IO software may select block producers through a continuous approval voting system. Anyone may choose to participate in block production and will be given an opportunity to produce blocks, provided they can persuade token holders to vote for them. The EOS.IO software enables blocks to be produced exactly every 0.5 second and exactly one producer is authorized to produce a block at any given point in time. If the block is not produced at the scheduled time, then the block for that time slot is skipped. When one or more blocks are skipped, there is a 0.5 or more second gap in the blockchain. Using the EOS.IO software, blocks are produced in rounds of 126 (6 blocks each, times 21 producers). At the start of each round 21 unique block producers are chosen by preference of votes cast by token holders. The selected producers are scheduled in an order agreed upon by 15 or more producers. Byzantine Fault Tolerance is added to traditional DPOS by allowing all producers to sign all blocks so long as no producer signs two blocks with the same timestamp or the same block height. Once 15 producers have signed a block the block is deemed irreversible. Any byzantine producer would have to generate cryptographic evidence of their treason by signing two blocks with the same timestamp or blockheight. Under this model a irreversible consensus should be reachable within 1 second."
7. How does the voting process work?
The voting process will begin once the Block Producer community releases a joint statement ensuring that it is safe to import private keys and vote. Broadly speaking there will be two methods of voting:
Command Line Interface (CLI) tools
EOS Canada has created eosc, a CLI tool that supports Block Producer voting. Other Block Producer candidates such as LibertyBlock are a releasing web portal that will be ready for main net launch. There will be many more options over the coming weeks, please make sure you are always using a service from a trusted entity. Remember: Do not import your private key until you have seen a joint statement released from at least five Block Producers that you trust which states when it is safe to do so. Ignoring this warning could result in tokens lost.
8. What makes EOS a good investment?
Team - EOS is spearheaded by the visionary that brought us the hugely successful Bitshares and Steem - arguably with two projects already under his belt there is no one more accomplished in the space.
Funding - EOS is one of the best funded projects in the space. The block.one team has committed $1B to investing in funds that grow the EOS echo system. EOS VC funds are managed by venture leaders distributed around the world to insure founders in all markets have the ability to work directly with local investors. Incentives such as the EOS hackathon are also in place with $1,500,000 USD in Prizes Across 4 Events.
Community Focus - The team is aware that the a projects success depends almost entirely on its adoption. For this reason there has been a huge push to develop a strong world wide community. There is already a surplus number of block producers that have registered their interest and started to ready themselves for the launch and incentives the EOS hackathon are being used to grow the community. A index of projects using EOS can be found at https://eosindex.io/posts.
Technical Advantages - See point 9!
9. What are the unique selling points of EOS?
Potential to scale to millions of transactions per second
This depends entirely on your definition of working product. If a fully featured developer release meets your definition then yes!. Otherwise the public release will be June 2018.
EOS differs from other projects in that it aims to deliver a fully featured version of the software on launch. The Dawn 3.0 RC1 feature complete pre-release became available on April 5th. This version has all the features of the final release that is due June 2018. Further development will involve preparing the final system contract which implements all of the staking, voting, and governance mechanics. The common notion that there is no viewable code published is wrong and the initial Dawn 1.0 release has been available from September 14th 2017.
11. EOS is an ERC-20 token, how can it possibly be a competitor to other platforms?
The ERC-20 token is used only for raising funds during the token distribution; all tokens will be transferred to the native blockchain once launched.
EOS team has clearly stated their reason for choosing the Ethereum network when they described the rationale behind the ICO model. Specifically, the ICO should be a fair and auditable process, with as little trust required as possible. If you believe that an ICO should be fair, auditable, and trustless, you have no choice but to use a decentralized smart contract blockchain to run the ICO, the largest, and by-far most popular of which is Ethereum. Since EOS is intended to be a major competitor for Ethereum, some have seen this as a hypocritical choice. - Stolen from trogdor on Steam (I couldn’t word it any better myself).
12. Why do the eos.io T&C’s say the ERC-20 token has no value?
The EOS T&C’s famously state:
"The EOS Tokens do not have any rights, uses, purpose, attributes, functionalities or features, express or implied, including, without limitation, any uses, purpose, attributes, functionalities or features on the EOS Platform."
This is legal wording to avoid all the legal complications in this emerging space, block.one do not want to find themselves in a lawsuit as we are seeing with an increasing amount of other ICOs. Most notably Tezos (links below).
This all comes down to legal issues. Anyone who’s been into crypto for 5 minuets knows that government bodies such as the Securities and Exchange Commission (SEC) are now paying attention to crypto in a big way. This legal wording is to avoid all the legal complications in this emerging space, block.one do not want to find themselves in a lawsuit as we are seeing with an increasing amount of other ICOs. Many token creators that launched ICOs are now in deep water for selling unregistered securities.
A filing from the Tezos lawsuit:
"In sum, Defendants capitalized on the recent enthusiasm for blockchain technology and cryptocurrencies to raise funds through the ICO, illegally sold unqualified and unregistered securities, used a Swiss-based entity in an unsuccessful attempt to evade U.S. securities laws, and are now admittedly engaged in the conversion, selling, and possible dissipation of the proceeds that they collected from the Class through their unregistered offering."
To ensure EOS tokens are not classed as a unregistered security block.one has made it clear that they are creating the EOS software only and won’t launching a public blockchain themselves. This task is left down to the community, or more precisely, the Block Producers (BPs). The following disclaimer is seen after posts from block.one:
"block.one is a software company and is producing the EOS.IO software as free, open source software. This software may enable those who deploy it to launch a blockchain or decentralized applications with the features described above. block.one will not be launching a public blockchain based on the EOS.IO software. It will be the sole responsibility of third parties and the community and those who wish to become block producers to implement the features and/or provide the services described above as they see fit. block.one does not guarantee that anyone will implement such features or provide such services or that the EOS.IO software will be adopted and deployed in any way.”
It is expected that many blockchains using eos.io software will emerge. To ensure DAPPs are created on an ecosystem that aligns with the interests of block.one a $1bn fund will be has been created to incentivise projects to use this blockchain.
“A lot of token distributions only allow a small amount of people to participate. The EOS Token distribution structure was created to provide a sufficient period of time for people to participate if they so choose, as well as give people the opportunity to see the development of the EOS.IO Software prior to making a decision to purchase EOS Tokens.”
It is also worth noting that block.one had no knowledge how much the the token distribution would raise as it is determined by the free market and the length of the token distribution is coded into the Ethereum smart contract, which cannot be changed.
14. Where is the money going from the token distribution?
Funding for the project was raised before EOS was announced, the additional money raised from the token distribution is largely going to fund projects on EOS.
A large portion of the money raised is getting put back into the community to incentivise projects using eos.io software. block.one raised all the money they needed to develop the software before the ERC-20 tokens went on sale. There are some conspiracies that block.one are pumping the price of EOS using the funds raised. The good thing about blockchain is you can trace all the transactions, which show nothing of the sort. Not only this but the EOS team are going to have an independent audit after the funding is complete for piece of mind.
From eos.io FAQ:
“block.one intends to engage an independent third party auditor who will release an independent audit report providing further assurances that block.one has not purchased EOS Tokens during the EOS Token distribution period or traded EOS Tokens (including using proceeds from the EOS Token distribution for these purposes). This report will be made available to the public on the eos.io website.”
A more complete list of EOS projects can be found at eosindex.io.
16. Dan left his previous projects, will he leave EOS?
When EOS has been created Dan will move onto creating projects for EOS with block.one.
When a blockchain project has gained momentum and a strong community has formed the project takes on a life of its own and the communities often have ideas that differ from the creators. As we have seen with the Bitcoin and Ethereum hark forks you cant pivot a community too much in a different direction, especially if its changing the fundamentals of the blockchain. Instead of acting like a tyrant Dan has let the communities do what they want and gone a different way. Both the Bitshares and Steem were left in a great position and with Dans help turned out to be two of the most successful blockchain projects to date. Some would argue the most successful projects that are actually useable and have a real use case. What Dan does best is build the architecture and show whats possible. Anyone can then go on to do the upgrades. He is creating EOS to build his future projects upon it. He has stated he loves working at block.one with Brendan and the team and there is far too much momentum behind EOS for him to possibly leave.
No one could have better knowledge on this subject than our Block Producer candidates, I have chosen to look to EOS New York for this answer:
"DDoS'ing a block producing is not as simple as knowing their IP address and hitting "go". We have distributed systems engineers in each of our candidate groups that have worked to defend DDoS systems in their careers. Infrastructure can be built in a way to minimize the exposure of the Block Producing node itself and to prevent a DDoS attack. We haven't published our full architecture yet but let's take a look at fellow candidate EOSphere to see what we mean. As for the launch of the network, we are assuming there will be attacks on the network as we launch. It is being built into the network launch plans. I will reach out to our engineers to get a more detailed answer for you. What also must be considered is that there will be 121 total producing and non-producing nodes on the network. To DDoS all 121 which are located all around the world with different security configurations at the exact same time would be a monumental achievement."
18. If block producers can alter code how do we know they will not do so maliciously?
Block producers are voted in by stake holders.
Changes to the protocol, constitution or other updates are proposed to the community by block producers.
Changes takes 2 to 3 months due to the fact block producers must maintain 15/21 approval for a set amount of time while for changes to be processed.
To ensure bad actors can be identified and expelled the block.one backed community will not back an open-entry system built around anonymous participation.
For this question we must understand the following.
Governance and why it is used.
The process of upgrading the protocol, constitution & other updates.
Dan’s view on open-entry systems built around anonymous participation.
Governance Cryptography can only be used to prove logical consistency. It cannot be used to make subjective judgment calls, determine right or wrong, or even identify truth or falsehood (outside of consistency). We need humans to perform these tasks and therefore we need governance! Governance is the process by which people in a community:
Reach consensus on subjective matters of collective action that cannot be captured entirely by software algorithms;
Carry out the decisions they reach; and
Alter the governance rules themselves via Constitutional amendments.
Embedded into the EOS.IO software is the election of block producers. Before any change can be made to the blockchain these block producers must approve it. If the block producers refuse to make changes desired by the token holders then they can be voted out. If the block producers make changes without permission of the token holders then all other non-producing full-node validators (exchanges, etc) will reject the change.
Upgrade process The EOS.IO software defines the following process by which the protocol, as defined by the canonical source code and its constitution, can be updated:
Block producers propose a change to the constitution and obtains 15/21 approval.
Block producers maintain 15/21 approval of the new constitution for 30 consecutive days.
All users are required to indicate acceptance of the new constitution as a condition of future transactions being processed.
Block producers adopt changes to the source code to reflect the change in the constitution and propose it to the blockchain using the hash of the new constitution.
Block producers maintain 15/21 approval of the new code for 30 consecutive days.
Changes to the code take effect 7 days later, giving all non-producing full nodes 1 week to upgrade after ratification of the source code.
All nodes that do not upgrade to the new code shut down automatically.
By default, configuration of the EOS.IO software, the process of updating the blockchain to add new features takes 2 to 3 months, while updates to fix non-critical bugs that do not require changes to the constitution can take 1 to 2 months.
Open-entry systems built around anonymous participation To ensure bad actors can be identified and expelled the block.one backed community will not back an open-entry system built around anonymous participation. Dan's quote:
"The only way to maintain the integrity of a community is for the community to have control over its own composition. This means that open-entry systems built around anonymous participation will have no means expelling bad actors and will eventually succumb to profit-driven corruption. You cannot use stake as a proxy for goodness whether that stake is held in a bond or a shareholder’s vote. Goodness is subjective and it is up to each community to define what values they hold as good and to actively expel people they hold has bad. The community I want to participate in will expel the rent-seeking vote-buyers and reward those who use their elected broadcasting power for the benefit of all community members rather than special interest groups (such as vote-buyers). I have faith that such a community will be far more competitive in a market competition for mindshare than one that elects vote buyers."
19. What is the most secure way to generate EOS key pairs?
Block producer candidates EOS Cafe and EOS New York have come forward to help the community with this topic. The block producer candidate eosnewyork has kindly posted a tutorial on steemit detailing the steps that need to be taken to generate key pairs using the official code on the EOS.IO Github. The block producer candidate eoscafe has gone a step further and released an Offline EOS Key Generator application complete with GUI for Windows, Linux & Mac. Not only can this application generate key pairs but it can also validate key pairs and resolve public keys from private keys. This application has also been vouched for by EOS New York
