Just a Wink and Smile - the Avaddon Pathway to Doom

The new Avaddon ransomware has come alive in an enormous spam campaign targeting online users with emails containing a wink emoji.
What is happening The Avaddon ransomware is being propagated via the Phorphiex/Trik botnet. The malspam messages try to entice the recipients into opening a photo, with a wink emoji in the email body. The phishing email contains a zip file that contains a JavaScript file. Once the JavaScript file is launched, the Trik worm, Gozi banking trojan, CryptoNight XMRig cryptocurrency miner, and Gandcrab ransomware are loaded.
Looking into the past Phorphiex/Trik botnet is one of the few botnets capable of packing a strong payload punch. Trik botnet is at least a decade old and first was dissipated via live chat and USB storage drives. While last year’s campaign contained female names in the phishing email, this year the display names were male. In 2018, 43 million email addresses leaked from the C&C server of the botnet.
Worth noting The monetary demand varies and payment is accepted in bitcoins. Their site contains 24/7 support assistance and ways to obtain bitcoin, along with a QR code and wallet address for payment. The operators are targeting users worldwide, proven by the presence of 9 language options on their site. The related IOCs can be found here.
The bottom line The threat actors behind Avaddon have posted on Russian hacker forums that they are a Ransomware-as-a-Service (RaaS) program. Following the RaaS rules, the actors will not target the Commonwealth of Independent States. Security experts expect to see a rise in advanced attack tactics and increasing distribution of the ransomware.

Mining and Dogecoin - Some FAQs

Hey shibes,
I see a lot of posts about mining lately and questions about the core wallet and how to mine with it, so here are some facts!
Feel free to add information to that thread or correct me if I did any mistake.

You downloaded the core wallet

Great! After a decade it probably synced and now you are wondering how to get coins? Bad news: You don't get coins by running your wallet, even running it as a full node. Check what a full node is here.
Maybe you thought so, because you saw a very old screenshot of a wallet, like this (Version 1.2). This version had a "Dig" tab where you can enter your mining configuration. The current version doesn't have this anymore, probably because it doesn't make sense anymore.

You downloaded a GPU/CPU miner

Nice! You did it, even your antivirus system probably went postal and you started covering all your webcams... But here is the bad news again: Since people are using ASIC miners, you just can't compete with your CPU hardware anymore. Even with your more advanced GPU you will have a hard time. The hashrate is too high for a desktop PC to compete with them. The blocks should be mined every 1 minute (or so) and that's causing the difficulty to go up - and we are out... So definitly check what is your hashrate while you are mining, you would need about 1.5 MH/s to make 1 Doge in 24 hours!

Mining Doge

Let us start with a quote:
"Dogecoin Core 1.8 introduces AuxPoW from block 371,337. AuxPoW is a technology which enables miners to submit work done while mining other coins, as work on the Dogecoin block chain."
- langerhans
What does this mean? You could waste your hashrate only on the Dogecoin chain, probably find never a block, but when, you only receive about 10.000 Dogecoins, currently worth about $25. Or you could apply your hashrate to LTC and Doge (and probably even more) at the same time. Your change of solving the block (finding the nonce) is your hashrate divided by the hashrat in sum - and this is about the same for Doge and LTC. This means you will always want to submit your work to all chains available!

Mining solo versus pool

So let's face it - mining solo won't get you anywhere, so let's mine on a pool! If you have a really bad Hashrate, please consider that: Often you need about $1 or $2 worth of crypto to receive a payout (without fees). This means, you have to get there. With 100 MH/s on prohashing, it takes about 6 days, running 24/7 to get to that threshold. Now you can do the math... 1 MH/s = 1000 KH/s, if you are below 1 MH/s, you probably won't have fun.

Buying an ASIC

You found an old BTC USB-miner with 24 GH/s (1 GH/s = 1000 MH/s) for $80 bucks - next stop lambo!? Sorry, bad news again, this hashrate is for SHA-256! If you want to mine LTC/Doge you will need a miner using scrypt with quite lower numbers on the hashrate per second, so don't fall for that. Often when you have a big miner (= also loud), you get more Hashrate per $ spent on the miner, but most will still run on a operational loss, because the electricity is too expensive and the miners will be outdated soon again. Leading me to my next point...

Making profit

You won't make money running your miner. Just do the math: What if you would have bougth a miner 1 year ago? Substract costs for electricity and then compare to: What if you just have bought coins. In most cases you would have a greater profit by just buying coins, maybe even with a "stable" coin like Doges.

Cloud Mining

Okay, this was a lot of text and you are still on the hook? Maybe you are desperated enough to invest in some cloud mining contract... But this isn't a good idea either, because most of such contracts are scams based on a ponzi scheme. You often can spot them easy, because they guarantee way to high profits, or they fake payouts that never happened, etc.
Just a thought: If someone in a subway says to you: Give me $1 and lets meet in one year, right here and I give you $54,211,841, you wouldn't trust him and if some mining contract says they will give you 5% a day it is basically the same.
Also rember the merged mining part. Nobody would offer you to mine Doges, they would offer you to buy a hashrate for scrypt that will apply on multiple chains.

Alternative coins

Maybe try to mine a coin where you don't have ASICs yet, like Monero and exchange them to Doge. If somebody already tried this - feel free to add your thoughts!

Folding at Home (Doge)

Some people say folding at home (FAH - https://www.dogecoinfah.com/) still the best. I just installed the tool and it says I would make 69.852 points a day, running on medium power what equates to 8 Doges. It is easy, it was fun, but it isn't much.
Thanks for reading

I earned about 4000% more btc with my android tablet than with a $250 ASIC mini rig setup using GekkoScience Newpac USB miners!

Requirements:
1.) Android Device with access to Google Play Store. *I haven't tried yet but you may be able to use tis on Android TV devces as well by sideloading. If anyone has success before I try, let me know! -Note, I did this with a Samsung Galaxy Tab S6 so its a newer more powerful device. If your android is older, your profts will most likely be less than what I earned but to give a projected range I also tested on my Raspberry Pi 4 running a custom LineageOS rom that doesn't allow the OS to make full use of the Pi's specs and I still got 500 h/s on that with Cloud boost, so about 60% of what my Tab 6 with MUCH Higher Specs does.
**Hey guys. Before I get started i just wanted to be clear about one thing. Yes I have seen those scammy posts sharing "miracle" boosts and fixes. I have a hard time believing stuff online anymore. But this is honestly real. Ill attach photos and explain the whole story and process below. Thanks for taking the time to read and feel free to share any thoughts, concerns, tips, etc*
So last week I finally got started with my first mini rig type mining build. I started getting into crypto about a year ago and it has taken me a long time to even grasp half of the projects out there but its been fun thus far! Anyways my rig was 2 GekkoScience Newpac USB miners, a Moonlander USB miner to pair with an FPGA i already had mining, a 10 port 60W 3.0 USB hub and 2 usb fans. The Newpacs actually are hashing at a combined 280 g/s which is actually better than their reported max hash rate when overclocked. Pleasant surpise and they are simple!! I just wanted to get a moonlander because my fpga already mines on Odocrypt for DGB and I just wanted to experience Scrypt mining and help build the DGB project. The Newpacs are mining BTC though.
After I got everything up and running i checked my payout daily average after 1 week. I averaged .01 a day TOTAL between all three miners with them all perforing ABOVE SPEC!!! I had done research so i knew I wouldnt earn much. More than anything i just wanted to learn. But still. I was kinda surprised in a negative way. Yesterday I actually earned less than .01 Frustrated I went back to scouring the web for new ideas. About a year ago, when II was starting, I saw an app on my iphone called CryptoBrowser that claimed to mine btc on your phone without actually using phone resources using a method of cloud mining. I tried it for a week and quit because I earned like .03 after a ton of use and seemed scammy. Plus my iphone actually would get very hot when doing this so I quit using it as it seemed like a possible scam with all the cryptonight browser mining hacks and malware out there.
Anyways I was on my Galaxy Tab S6 and saw that CryptoBrowser released a "PRO" edition for 3.99 on Google Play. I bought it for Sh*ts and giggles and booted it up. It came with what they called "Cloud Boost" Essentially this is a button you press and it multiplys the estimated hashrate that it gives you device by the number shown on the boost button. (With the purchase of PRO you get one free x10 boost. You can purchase additional boosts to use with other android devices but those are actually pretty pricy. Another x10 boost was like $25 if i remember correctly).
I played with it for about an hour to see if it actually worked like it said it would this time. To my surprise, as i was browsing, my device didnt increase in temperature AT ALL!!!!! I checked my tast manager to confirm and it was indeed true, my memory and usage barely went up. it was giving me an estimated range of 80-105 on the hashrate. Once i pushed the x10 boost button, that went to 800-1150 h/s. I switched my screen to not go to sleep, plugged it to the charge and let it run on the browser page, hashing. When you push the boost button, it runs for 3 hours at the boosted speeds. After that it goes back to normal but if you press the button again, it boosts everything again. There is no limit to how many times you use it. After checking what I earned after 24 hours, I HAD MADE .40 in BTC!!!!! I JUST EARNED OVER 4000% MORE THAN MY $280 MINING RIG EARNED ME!!!! I was blown away. Maybe this was a fluke? I did it again next day. Every 3 hours or so I would push the button again but thats all. Sure enough, .35 that day. Also, it realy BTC. I requested a payout and although it took like 12 hours for them to send me an email stating they had just sent it, I actually did recieve the state amount of BTC within 24 hours in my personal wallet. The fees to send are SUPER LOW!. Like .01
Below I will list the steps I took, along with an explanation of thier "Mining" process on Androids. Reminder, this ONLY WORKS ON ANDROIDS. Also DO NOT use cryptobrowser on a physcal laptop or desktop. I ran it on an old laptop for three days last year and it fried it. It does actually use your hardware on those platforms to mine and it is not efficnet at all as I suspect they prob steal over half of your power for themselves using the REAL RandomX protocol via browser mining which is EXTREMELY INEFFICIENT DONT TRY IT!!
-----How To Do This Yourself:
Cryptotab Browser states the program works on Android devices by estimating what it thinks the hashrate would be for your device specs and siimulates what you would mine in a remote server however you still earn that estimated coin amount. It is not a SHA-256 process or coin that they say is mining, rather it is XMR and they swap that and pay it out to you in BTC Bitcoin. However I know damn well my Tab S6 doesnt hash 80-105 h/s on RandomX because I have done it with a moodified XMRig module i ported to Android. I got 5 h/s a sec if I was getting any hashes at all. But thats besides the point as I still was making money.
Now, when you press that cloud boost button it immediately boosts that hash rate it estimates by the number on the cloud boost. As stated above, you can purchase more boosts and gift them or use them on extra android devices that you may have. Again, they are pricey so I'm not doing that plus it would just mean that I have another device that I have to leave on and open. The boosts come in x2, x4, x6, x8 and x10 variants. Again, they have unlimited uses.
Here is the link to grab yourself CryptoBrowser Pro from CryptoTab. This IS A REFERRAL LINK! This is where I benefit from doing tis tutorial. Like i said, I want to be transparent as this is not a scam but I'm also not doing this out of the love of my heart. Their referral system works in that people that use the donwload the app using your link are your stage 1 referrals. Anytime they are mining, you earn a 15% bonus. So say they mine $.30 one day. You would get paid out an additional $.045 in your own balance (it does not come out of the referred user balance fyi so no worries). Then lets say that referred miner also gets their own referrals. I would get a 10% bonus on whatever THOSE people mine. This goes on and on for like 8 tiers. Each tier the bonus percntage essential halves. So again, I stand to benefit from this but it also is stupid to not make this visible as its WAY CHEAPER, EASIER AND MORE PROFITABLE TO GET BTC USING THIS METHOD THAN IT IS USING ASICS!! THIS EARNS ALMOST AS MUCH BTC AS AN ANTMINER S7 DOES RUNNING 24/7 ONLY WITHOUT THE HUGE ELLECTRICTY BILL AND COSTS!!!!)
Thats it. Again, if you have concerns, let me know or if you have suggestions, other tips, etc... mention those as well!!!

We’ve been working on a new product release for a year and want to hear your opinions on the product. Read on for product information and our vision for hardware wallets.

TL;DR Key features of Cobo Vault 2nd gen we are going to launch:
Hey bitcoin! I'm Lixin, a longtime Bitcoiner and creator of Cobo Vault.
I come from a background in the electronic hardware industry, and experienced one of my products being featured in Apple Stores around the world. Although my interest goes back to 2010, my career intersected Bitcoin when Discus Fish (CEO of Cobo) invited me to help build Cobo’s hardware product line. Discus Fish is also the co-founder and CEO of f2pool, one of the largest mining pools currently in the world, and one of the earliest advocates of bitcoin in China.
Back in 2018 we built our 1st generation Cobo Vault hardware wallet. As we had strong ties to miners in China, we naturally designed the 1st gen with them in mind. For those who are not familiar with the mining industry in China, mining farms are nearly always built in very isolated places where there is very cheap wind or water electricity. As the miners would take their storage into these isolated regions, we needed to maximize the durability of the device in addition to its security. We used aerospace aluminum rather than plastic and made it completely IP68 waterproof. We also gave it a hardshell metal case you can put it in, which is IK9 drop resistant and passes the American military durability test MIL-STD-810G.
As for the electronic components inside the device, in order to maximize security, we made it as air-gapped as possible with QR codes. We see this as an important choice because USB cables and Bluetooth are not transparent and have a bigger attack surface. With QR codes you can see exactly what is going on and do not have to connect to a laptop which could have malware on it. QR code interaction needs a camera and a more complicated system which needs to be supported by high-level chips.
All these come with a cost, and the 1st generation isn’t as accessible for average hodlers. For more details on the product, visit here.
Things changed last year when I went to Bitcoin 2019 and talked to lots of hodlers in the States. I found that 95% of them don’t care about durability. I asked them if they were afraid of their home being flooded or burned down in a fire. The answer is - yes, they are afraid of these things, but see them as very low possibilities. Even if something were to happen, they said they would just buy another HW wallet for 100 dollars. From these conversations, it became more and more clear that the position for miners and hodlers is totally different.
After coming back from that conference, our team began the almost one year journey of designing our 2nd gen product. It compromises on durability but doesn’t compromise on security.
We designed the 2nd gen product all around a normal hodler’s needs.
Obviously hodlers share some common needs with miners:
If you'd like to read more about these features, check out our blog posts here.
Aside from these legacies from the 1st gen, our 2nd gen product will have some other big improvements:
Personally, I am a bitcoin maximalist and also a big fan of the KISS principle. We will also release a BTC-only firmware version for people who want to minimize the codebase for less of an attack surface.
Thank you for reading until here. More details like final price would be released later when we officially release the product in late Apr. Any suggestions or questions are welcome. Also you can find me @CryptoLixin or @CoboVault on Twitter! Ears are widely open!

Groestlcoin 6th Anniversary Release

Introduction

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

UPDATED - Groestlcoin Core 2.18.2

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

ALL NEW! – HODL GRS Android Wallet

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

ALL NEW! – Vanity Search Vanity Address Generator

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

ALL NEW! – Electrum Personal Server

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

I have a Bitcoin Core Wallet from 2013.

So, from around 2010 to 2014 I used to mess around with mining Bitcoin. I started with CPU mining then bought a dozen of those usb asic miners then acquired a couple blade miners. My backup was to have multiple copies of my Core wallet so I wouldn't lose the coins. My failure was to keep multiple copies of the password. I used KeePass to store my password. Long story short, the KeePass database appears to be lost forever. I only know that the password is 32 characters long. By examining passwords generated by the software I can assume that it only contains no more than 3 of each characters and no two characters repeat simultaneously. It could contain upper case, lower case, and special characters.
With my video card I can only brute force 5000 passwords per second. At today's bitcoin price it is not practical to invest in more computing power but someday for my kids it could be worth it.
Right now it is just a project I am working on because these challenges intrigue me. I assume with a 12 GPU mining rig I could get more than 60,000 passwords per second but it would still be a matter of luck to crack it before I die.
...and go

Why does Coinbase need my ID?

So I've had my wallet with coinbase for a pretty long time and my account recently got disabled, I've contacted support and they apparently need me to send them some form of ID (passport Driving licence etc) Since I trust this about as much as an anonymous user on 4chan what else can I do to store my litteral pennies worth of Bitcoin?
Side note I have a Bitgretiefter Yellowjacket USB Miner which decided it didn't want to work on windows 10 anymore so suggestions would be appreciated...

Lottery/Solo Mining

I have set up a small rig, with a few usb miners that i managed to get for a cheap price, was reading about on forums and read about setting up your own node and mine on your own, in hope to mine a whole block. I have set up everything, switched on cgminer and passed on a few parameters... -o -u -p and --btc-address. Now my question is, for the --btc-address parameter, i need to insert my receiving bitcoin address ? can i use one from my hardware wallet or does it have to be one that the Bitcoin-QT (Bitcoin Core) that cgminer is attached to ?

[ELI5] How to send coins using Coinb.in

How to send coins from ANY wallet using https://coinb.in/#settings

Why?

Because cold wallets, such as those stored offline in a text file as I keep recommending in my standard advice below:
All you need is a text file to put your wallets in, like this example from https://walletgenerator.net/?currency=Dogecoin
1,"D7WBUpdgLRtG6WyPsqjhaKiJR65X8ZGnkZ","6KieLMW1poAzNVnmLuQZqA262gxEQ51eLGdDK8e2GL2B4LHCKKb" 2,"DM8LT16d49zHr8ByXbUwZb9UBXDGMaZRdc","6Ktgxdv6vN9v2bDHwcJBBb3oMRAgXJumESzBnxaXUSGFZoq6pWQ" 3,"D5UCa51AfxjtVHQ46oYXe2YfkctTeLXPhx","6L2WSPWadRYCwt2L1CxH6zC7PoTYY3KyjxdiUoCqi5eyq6hQKvj"
Use https://coinb.in/#settings to move coins. Download both sites and run them offline. Use https://bitinfocharts.com/dogecoin/ to check balances and transactions. See http://www.mocacinno.com/blog/create-sign-broadcast-transactions-using-coinb/ for coinb.in tutorial. And read the ELI5s (and my history) for more info.
Are without doubt THE SAFEST way to store your coins. Plus, they consume no resources. No bandwidth, no network stress for every node we have, no storage of 20Gb+ blockchains, no weeks of waiting for things to sync, no tearing your hair out and posting desperate pleas for help, and most importantly, no coins irretrievably lost because you or your client screwed up.

What?

Wallets, ALL WALLETS are nothing but numbers. Very large numbers, but fundamentally no different from “7”, “42”, “911” or a phone number. They cannot be created nor destroyed, and you either know them or you don’t. Anyone who knows a key can use it to spend any coins it controls. Anyone who doesn’t know it, can’t. Don’t be the guy who doesn’t know his own keys. Keep them safe. Make copies. Keep those safe. Don’t let your friends, kid brother or random burglar find them, but don’t lose them either.
The only other thing you need for a fully functional wallet is a way to spend coins. Coinb.in is such a way. There are others, such as DogeCoinMultiSig.org which tomcarbon built.
Oh, and you can and should download it and run it locally.

Where?

The default entry point for coinb.in is https://coinb.in/#settings because this settings page is very well hidden. Its in the tiny gear wheel on the Broadcast page.
Looking across the top of the page, you can see
  • + New
  • Verify
  • Sign
  • Broadcast
  • Wallet
  • About
We’re only going to use three of these. New, Sign, Broadcast.
Now, keep in mind that coinb.in is an old Bitcoin tool which tomcarbon added Dogecoin to. Sometimes it thinks its dealing with Bitcoin still, so if you see anything odd, go and make sure you’ve selected Dogecoin in the Settings page.

When?

This tool should be the only place you spend coins. Sure, some clients may look more convenient, but they all suffer from a very big coin-losing flaw. Whenever you split a UTXO, they create a new wallet to send the change to. And they DON’T TELL YOU! This means unless you back up after every transaction, you run a high risk of finding all your coins have ‘disappeared’ from your wallet, and you don’t recognise where they went.
So if you use a client for the convenience as well as a text list of your wallets, you won’t know to add a new wallet to your masterfile. Its best to ditch the clients entirely.

How?

Now we come to the nitty-gritty. Lets use those three wallets above and assume that #1 is the source, #2 the destination and #3 the change wallet. Note that these won’t actually work, as none of them have ever been used, but they will do as examples.
New Transaction
Located at the bottom of the New menu, this will give you a page to enter your wallets and amounts.
In the top field, you enter your source address or Key. If you use the key, it will calculate the address when you click the Load button, which should match what you expected. Note that Load only brings in the first 100 UTXOs. This is so that you can retrieve coins from high-volume wallets which would kill any client. Coinb.in is in fact the ONLY WAY to do this, as even QT falls over around 600 UTXOs.
You will see the total balance that was loaded in the Transaction Fee field. And also in the Inputs tab, where you can go to adjust which UTXOs to spend.
Now you need to add the wallet(s) and amounts to send to them. Lets suppose the source contained a single UTXO for 1,000 Doge. You want to send 500 of them. So you would enter the #2 address in the Address field, and 500 in the Amount field. The Fee now changes to 500, which is not what you want.
So you click the + button to bring up a new line, enter the change address and the other 500, making the fee zero.
And you’re done. Check that the Fee is indeed zero. Check that the amounts shown in the Outputs and Inputs tabs match exactly.

THIS IS CRITICAL!

There is a bug which will send all the coins to the miners if the Outputs exceed the Inputs. I would have expected the Fee to show as negative in such a situation, but it doesn’t. BE WARNED!
Once everything looks right, hit the Submit button.
This will give you a block of hex code. Copy it.
Sign
Go to the Sign tab and paste it. Add your private key for the source wallet and click Submit. Note this can be done offline for safety.
This will give you another block of hex, the SIGNED transaction.
Broadcast
Copy this and paste it in the Broadcast tab and click Submit.
That’s it. Your coins are on their way. Make a cuppa and settle in while they arrive in a minute or three.
Note: All fields retain their values unless you refresh the page! This can be a boon when doing multiple transactions, such as when emptying a huge wallet. But it can also be a trap for the unsuspecting. Refresh or close the window when you’re done.

Who?

Who should use this?
Absolutely EVERYONE!
Even if you’re wedded to your client in some satanic blood-contract, you should still know how this works, because sooner or later you’re going to have a problem you can’t fix without it.
Definitely download the site and store it on every device you have. On every USB backup of your wallets. On your phone (well, except iOS which doesn’t do local HTML), etc, etc, etc.
Oh, and if you’re a programmer SmartyShibe, do consider improving the code over on GitHub.

What is a Cryptocurrency Wallet?

What is a Cryptocurrency Wallet?
Use this straightforward guide to learn what a cryptocurrency wallet is, how they work and discover which ones are the best on the market.
A cryptocurrency wallet is a software program that stores private and public keys and interacts with various blockchain to enable users to send and receive digital currency and monitor their balance. If you want to use Bitcoin or any other cryptocurrency, you will need to have a digital wallet.
How do they work?
Millions of people use cryptocurrency wallets, but there is considerable misunderstanding about how they work. Unlike traditional ‘pocket’ wallets, digital wallets don’t store currency. In fact, currencies don’t get stored in any single location or exist anywhere in any physical form. All that exists are records of transactions stored on the blockchain.
Cryptocurrency wallets are software programs that store your public and private keys and interface with various blockchain so users can monitor their balance, send money and conduct other operations. When a person sends you bitcoins or any other type of digital currency, they are essentially signing off ownership of the coins to your wallet’s address. To be able to spend those coins and unlock the funds, the private key stored in your wallet must match the public address the currency is assigned to. If public and private keys match, the balance in your digital wallet will increase, and the senders will decrease accordingly. There is no actual exchange of real coins. The transaction is signified merely by a transaction record on the blockchain and a change in balance in your cryptocurrency wallet.
What are the different types of Cryptocurrencywallets?
There are several types of wallets that provide different ways to store and access your digital currency. Wallets can be broken down into three distinct categories – software, hardware, and paper. Software wallets can be a desktop, mobile or online.
Are Cryptocurrency wallets secure?
Wallets are secure to varying degrees. The level of security depends on the type of wallet you use (desktop, mobile, online, paper, hardware) and the service provider. A web server is an intrinsically riskier environment to keep your currency compared to offline. Online wallets can expose users to possible vulnerabilities in the wallet platform which can be exploited by hackers to steal your funds. Offline wallets, on the other hand, cannot be hacked because they simply aren’t connected to an online network and don’t rely on a third party for security.
Although online wallets have proven the most vulnerable and prone to hacking attacks, diligent security precautions need to be implemented and followed when using any wallet. Remember that no matter which wallet you use, losing your private keys will lead you to lose your money. Similarly, if your wallet gets hacked, or you send money to a scammer, there is no way to reclaim lost currency or reverse the transaction. You must take precautions and be very careful!
Although Bitcoin is by far the most well-known and popular digital currency, hundreds of newcryptocurrencies (referred to as altcoins) have emerged, each with distinctive ecosystems and infrastructure. If you’re interested in using a variety of cryptocurrencies, the good news is, you don’t need set up a separate wallet for each currency. Instead of using a cryptocurrency wallet that supports a single currency, it may be more convenient to set up a multi-currency wallet which enables you to use several currencies from the same wallet.
Are there any transaction fees?
There is no straightforward answer here.
In general, transaction fees are a tiny fraction of traditional bank fees. Sometimes fees need to be paid for certain types of transactions to network miners as a processing fee, while some transactions don’t have any fee at all. It’s also possible to set your own fee. As a guide, the median transaction size of 226 bytes would result in a fee of 18,080 satoshis or $0.12. In some cases, if you choose to set a low fee, your transaction may get low priority, and you might have to wait hours or even days for the transaction to get confirmed. If you need your transaction completed and confirmed promptly, then you might need to increase the amount you’re willing to pay. Whatever wallet you end up using, transaction fees are not something you should worry about. You will either pay minuscule transaction fees, choose your own fees or pay no fees at all. A definite improvement from the past!
Are cryptocurrency wallets anonymous?
Kind of, but not really. Wallets are pseudonymous. While wallets aren’t tied to the actual identity of a user, all transactions are stored publicly and permanently on the blockchain. Your name or personal street address won’t be there, but data like your wallet address could be traced to your identity in a number of ways. While there are efforts underway to make anonymity and privacy easier to achieve, there are obvious downsides to full anonymity. Check out the DarkWallet project that is looking to beef up privacy and anonymity through stealth addresses and coin mixing.
Which Cryptocurrency wallet is the best?
There is an ever-growing list of options. Before picking a wallet, you should, however, consider how you intend to use it.
Bread Wallet
Bread Wallet is a simple mobile Bitcoin digital wallet that makes sending bitcoins as easy as sending an email. The wallet can be downloaded from the App Store or Google Play. Bread Wallet offers a standalone client, so there is no server to use when sending or receiving bitcoins. That means users can access their money and are in full control of their funds at all times. Overall, Bread Wallet’s clean interface, lightweight design and commitment to continually improve security, make the application safe, fast and a pleasure to use for both beginners and experienced users alike.
Mycelium
Advanced users searching for a Bitcoin mobile digital wallet, should look no further than mycelium. The Mycelium mobile wallet allows iPhone and Android users to send and receive bitcoins and keep complete control over bitcoins. No third party can freeze or lose your funds! With enterprise-level security superior to most other apps and features like cold storage and encrypted PDF backups, an integrated QR-code scanner, a local trading marketplace and secure chat amongst others, you can understand why Mycelium has long been regarded as one of the best wallets on the market.
Exodus
Exodus is a relatively new and unknown digital wallet that is currently only available on the desktop. It enables the storage and trading of Bitcoin, Ether, Litecoins, Dogecoins and Dash through an incredibly easy to use, intuitive and beautiful interface. Exodus also offers a very simple guide to backup your wallet. One of the great things about Exodus is that it has a built-in shapeshift exchange that allows users to trade altcoins for bitcoins and vice versa without leaving the wallet.
Copay
Created by Bitpay, Copay is one of the best digital wallets on the market. If you’re looking for convenience, Copay is easily accessed through a user-friendly interface on desktop, mobile or online. One of the best things about Copay is that it’s a multi-signature wallet so friends or business partners can share funds. Overall, Copay has something for everyone. It’s simple enough for entry-level users but has plenty of additional geeky features that will impress more experienced players as well.
Jaxx
Jaxx is a multi-currency Ether, Ether Classic, Dash, DAO, Litecoin, REP, Zcash, Rootstock, Bitcoin wallet and user interface. Jaxx has been designed to deliver a smooth Bitcoin and Ethereum experience. It is available on a variety of platforms and devices (Windows, Linux, Chrome, Firefox, OSX, Android mobile & tablet, iOS mobile & tablet) and connects with websites through Firefox and Chrome extensions. Jaxx allows in wallet conversion between Bitcoin, Ether and DAO tokens via Shapeshift and the import of Ethereum paper wallets. With an array of features and the continual integration of new currencies, Jaxx is an excellent choice for those who require a multi-currency wallet.
Armory
Armory is an open source Bitcoin desktop wallet perfect for experienced users that place emphasis on security. Some of Armory’s features include cold storage, multi-signature transactions, one-time printable backups, multiple wallets interface, GPU-resistant wallet encryption, key importing, key sweeping and more. Although Armory takes a little while to understand and use to it’s full potential, it’s a great option for more tech-savvy bitcoiners looking to keep their funds safe and secure.
Trezor is a hardware Bitcoin wallet that is ideal for storing large amounts of bitcoins. Trezor cannot be infected by malware and never exposes your private keys which make it as safe as holding traditional paper money. Trezor is open source and transparent, with all technical decisions benefiting from wider community consultation. It’s easy to use, has an intuitive interface and is Windows, OS X and Linux friendly. One of the few downsides of the Trezor wallet is that it must be with you to send bitcoins. This, therefore, makes Trezor best for inactive savers, investors or people who want to keep large amounts of Bitcoin highly secure.
Ledger Nano
The Ledger Wallet Nano is a new hierarchical deterministic multisig hardware wallet for bitcoin users that aims to eliminate a number of attack vectors through the use of a second security layer. This tech-heavy description does not mean much to the average consumer, though, which is why I am going to explain it in plain language, describing what makes the Ledger Wallet Nano tick. In terms of hardware, the Ledger Wallet Nano is a compact USB device based on a smart card. It is roughly the size of a small flash drive, measuring 39 x 13 x 4mm (1.53 x 0.51 x 0.16in) and weighing in at just 5.9g.
Pros:
Cons:
Green Address
Green Address is a user-friendly Bitcoin wallet that’s an excellent choice for beginners. Green Address is accessible via desktop, online or mobile with apps available for Chrome, iOS, and Android. Features include multi-signature addresses & two-factor authentications for enhanced security, paper wallet backup, and instant transaction confirmation. A downside is that Green Address is required to approve all payments, so you do not have full control over your spending
Blockchain (dot) info
Blockchain is one of the most popular Bitcoin wallets. Accessing this wallet can be done from any browser or smartphone. Blockchain.info provides two different additional layers. For the browser version, users can enable two-factor authentication, while mobile users can activate a pin code requirement every time the wallet application is opened. Although your wallet will be stored online and all transactions will need to go through the company’s servers, Blockchain.info does not have access to your private keys. Overall, this is a well-established company that is trusted throughout the Bitcoin community and makes for a solid wallet to keep your currency.

/r/Monero - Newcomers Please Read. Everything You Need To Know.

What is Monero (XMR)?
Monero is a secure, private, untraceable (crypto-)currency. It is open-source and freely available to all. Don't believe us? Click here.
Monero is a tool that people can actually use. It makes receiving payments hassle-free, since merchants and individuals no longer need to fear the source of funds they are accepting. With transparent systems like Bitcoin, Ethereum, Verge, or Dash, these people need to hope (or spend substantial resources verifying) the sender did not use the funds illicitly. Furthermore, merchants do not want all their vendors known, and individually do not want everyone to know how much they are spending. If I spend more than I should at Newegg (store), that's my own business.
Monero is different because every transaction is always private. There is no way for pools and exchanges to opt out of sending private transactions. Thus, Monero's anonymity set far exceeds any other coin's anonymity set. Over 86,000 transactions in the past month of August, 2017 hid the sender and receiver, and about 99.95% of them also hid the amount (will increase to 100% of all new transactions in September)! There is no suspicion in using a private transaction, since all transactions are private. A single transaction does not stick out.*
This privacy is afforded with the best technology. I implore you to take a few minutes to learn about the four main technologies that Monero uses to provide privacy:
There are several other things that make Monero great! It has a smooth tail emission, dynamic blocks and fees, and an accessible Proof of Work (mining) algorithm.
*You can optionally choose a very large, unusual ringsize to make the transaction stick out. This is not recommended, and normal users who leave the ringsize at the default setting will not experience any issues. Also, it's possible for a user to manually add identifying information to the tx_extra field, which is something that a user must seriously go out of their way to do.
Now you know Monero (XMR) has the best technology. What else makes Monero (XMR) different than other cryptocurrencies?
P.S. Want a quick-start, simple your-grandma-could-do-it guide? Here's a great one!
Am I a bad person to consider using this?
No, Monero is freedom money. You can do whatever you want with it, whenever you want, where ever you want. We make it clear that you should own your wealth 100%. What you do with it, is none of our concern.
Where does the word Monero come from?
The word Monero comes from the language Esperanto. Monero means coin oand currency. The plural way of saying Monero in Esperanto and in our cryptocurrency is Moneroj.
How do I store Monero?

Is there a lightweight wallet for Monero?
Not yet, but you can use the official GUI with a remote node.
Are there any other ways to store Monero (XMR)?
Yes, there are many mobile wallets out there that allow you to store Monero (XMR). We do not recommend them, because they are not official releases of Monero. If you do decide to use other wallets, please make sure to do your research first before storing any Moneroj in the wallet. Anything used for Monero outside of official releases, will be used at your own risk. Some may be used for scamming purposes. If you still decide to take the risk; do not use them for large amounts. Also keep in mind that there is a high chance that Monero support will not be able to help you if you bump into any problems from applications outside of official releases. Why should you not use non-official wallets? Well would you buy a house and give your only key you have to the buildemanagement and wait for him/her to open the door to the house you supposedly own? No. Same goes with cryptocurrencies. You should always have possession of your private keys, and your Moneroj. Most non-official releases own your private keys, therefore you do not own the Moneroj.

I hate my Fucking Mining Rig - Short Story of my mining adventure (Don't really hate it)

Wanted to write a short write up on my journey of Crypto mining for some of the newer people and people who want to get into it. Not trying to discourage anyone from starting, but want to show the progression of a newbie.
So I am a good with computers and learned of Bitcoin when it was about $7 a coin. Laughed at the idea of some computer doing some math and getting some BS currency. Million dollar mistake on my part, but hindsight is always 20/20.
Anyways, Learned about ethereum in May. Bought some at around $180 and bought all the way up to $330. Now to the mining rig. Ran all of the calculations and with a 180 hashrate and 900 watts I was gonna get 6-7 Eth per month. Shit was gonna be profitable in under 3 months. I was gonna be a fucking crypto allstar and be rich as fuck!
Bought all of my parts literally the day before they were nonexistent. Literally bought the last RX480's from Amazon. Here is a list of my parts.
Asrock board Pentium dual core processor 4 Gb of ram 128 gb SSD 1200 watt Rosewill PSU 6 Sata to Molex PCI Risers (Junk) 6 RX480's - 2 Asus Strix, 4 Gigabyte Total cost - Roughly $2,500 (Pennies compared to my future ROI)
Please keep in mind that I am not posting every single miner issue that I ran into such as fucking with Wattman for a few weeks before learning about Trixx and Afterburner.
I've built computers before, so that part wasn't hard. Set everything up and get windows 10 running.
Problem 1 - Computer doesn't see all of the cards. Had to run the drivers a few times and tweak some shit, but got all 6 cards seen.
Miner hurdle (See what I did there) but off to the races. Let's get this bitch running so I can begin planning my retirement.
Get Claymore running, Got Trixx to overclock. Ran my cards at -96, 1200, 2200 fans at 85% (Cause I'm cool like that.) Major stability issues from the start. 1 card (Asus) would crash all the time. Didn't know about the watch dog feature in claymore that would restart my rig when a card crashed. Great feature but my computer would go into this state of having power, but not loading the operating system. Even if it did restart, most of the time claymore would get stuck right before setting the dag's and would just lock up. (Claymore program is awesome by the way, this was my rigs fault)
Could not get this fucking Asus card to stop crashing, even on stock settings. Sent the bitch back RMA style. Asus said something was wrong and sent me a new one.
Awesome, lets get this bitch running. I need to start looking at sick houses in Costa Rica to move to once I am rich as Fuck!
New card makes things better for a few days. Not 100% stable but better. Go to vegas for a driving thing (Race cars - Future rich guy stuff) and this mechanical demon starts crashing every few hours. Luckily I had Google remote desktop installed so I could log on and restart it or change settings in Trixx. Had to have my GF unplug it and plug it in a few times.
Get back home, fuck with this thing but still random crashes on random cards. Decide it is the PCI risers. Contact seller who will send me some more for free. Slow boat from china took two weeks to get them. They arrive but still some of them are bad. Can't seem to piece together 6 good ones.
Did some research online (Ethereum Forum and Reddit) and decided to get some new style of risers V007 6 Pin to Sata ($70) and they take a month to get here. Plug them all in and they seem to be working much better. Decent stability, But I ain't got time for fucking stock bios. Let's ramp these bitches up and get 32 MHs per card at 600 watts from the wall!
Actually flashing the bios was pretty easy. Thank you 6 pound 9 ounce baby jesus! Long story short had some major stability issues and bounced around with some different timing straps before finding the right ones. (Uber 3.1 for Samsung memory)
So now that we've got some good hash speeds and decent stability let's ramp this private ATM up a little bit by dual mining some Decred. Get dual mining up and running. go to sleep. Wake up the next morning expecting to see myself on the top 100 forbes list. look at my mining rig stats on my phone and see that it died roughly and hour after I went to sleep. Walked toward my rig on the red carpet I had just installed and saw that it was off. Flicked on the light to check it out. No light, WTF? Well I'll be god damned, no power in this whole fucking room. Checked my breakers and sure enough this metal motherfucker tripped my breaker.
No worries though. I'm smart as fuck. I'll just undervolt the shit out of it to get the power down. No way in hell I am just mining ether. I'm going balls to the wall!
As you can expect I had many days of stability issues and tripped breakers. But fuck it, I have homeowners insurance. Burning it to the ground will be covered. (Didn't happen)
My surge protector must be maxed out. Let's buy a bigger one ($25). Same issues.
Fuck Decred, I'll mine SIA, less power. Damn I'm smart.
Rig is more stable with Sia and no tripped breakers. Family medical emergency, have to fly north for a few days. But my rig has been fairly stable and I've got remote desktop if anything goes wrong.
Arrive at airport, check mining stats, rig is down. No worries remote desktop. FUCK, not responsive, no way to remote into the rig and no way to remotely power it off and on.
Lost 4 days of mining. But no worries the difficulty is only, Holy shit that's high! But the price of Ether will make up for it. Ether crashed to the $200's. Oh well, maybe a 10 room house in Costa instead of a 12. No sweat.
Get back to my house and this whore of a machine is just sitting there in a computer coma. It's on but it's not. LED lights glaring at me like "Fuck you human, I ain't doing your stupid math problems!" Fuck you machine, I'm your master. You will do my math problems and you will fucking like it.
My AMD Drivers seem to disappear and the computer goes into a coma like state. Someone on Reddit suggested using the 16.9.2 drivers. Installed and they worked better.
Still random crashing. This shitty PSU must be maxed out. Fuck you PSU, I'm getting you a little brother (EVGA 750 gold $120.)
What do you mean you have to jerry rig a second PSU so it starts without being connected to a motherboard? 2 more hours of my life wasted.
But finally some stability. On my way to being fucking rich. I start looking at people in bentley's and can only laugh. You dumb fuck, I'm gonna be way richer then you. Gonna get a Bugatti for each day of the week.
Damn this difficulty is a bitch. Fuck you Genesis Mining and your pallets of GPU's. You're killing me smalls!
But anyway, on my way to rolling around in my fuck you money!
Fuck you dag file 135, you're killing my future millions. Fuck you dag 138, you dropped me to 167 mhs.
Thank god AMD was there to save my ass with their dope ass blockchain drivers.
download, run DDU, Restart, install drivers, restart, run pixel patch, restart. Perfect, I'm in the money now! I can taste the caviar and champagne already.
Now my cards only run 4 Mhs each. WTF? Try a bunch of the other new drivers. Same shit. Roll back to 16.9.2 and they run fine, just at 167 instead of 180.
Someone on a forum said he had the same issue and did a fresh install of windows 10 and it worked.
So I'll just reformat my SSD (Windows wouldn't do a fresh install within the operating system. Fuck you Bill Gates! Gonna buy you once I get this thing running at 180.)
Format SSD, plug back in, throw in my gangster ass boot USB drive. Ramdisk error. Fuck you Bill Gates! Reformat SSD multiple times, lots of forum reading. Install windows from another computer through command prompt (I'm a coder now as well.) This shit has got to work, I did it in command prompt bitches!
Same fucking error. Now down to an 8 bedroom house in Costa and only 6 Bugattis.
Let's try unplugging my 6 cards and see if that works. Thank you 6 pound 9 ounce baby jesus. Windows installed.
New drivers work and I'm back at 180! Raking in the cash now.
With those speeds my Asus cards crashed. Had to dial down the hashrate to 177.5 for them to be stable. So now going to use some commands in claymore to run the Asus cards at lower speeds while letting my other cards mine harder.
I wrote this to let people know that mining isn't all Bugatti's and caviar. These machines are fickle little cunts that do what they want. No system is the same. So when you post on a forum, people will give you advice on what may work. But what works for them, may not work on your rig. In the end it's up to you to figure it out.
I have spent countless hours after work and on weekends working on this bitch. Hell I've probably spent a few hours just staring at it and thinking about all of the ways I could destroy it slowly.
While I love Etheruem and do value the knowledge gained, I would have made more money just buying Eth and holding.
The guys you see on youtube building sick rigs with crazy specs have been at it for a while. They have worked through the process and know how to solve all of the problems. You have not and will have to work them out on your own.
My whore of a rig will pay for itself soon. But I would suggest that if you want to start building a new mining rig. Check the difficulty chart and make sure you have tons of free time to fuck with it.
I'd post my wallet address for donations since I just saved you $2,600. But I am afraid hackers will steal my monies :)
Hope you enjoyed my mining life story from the past few months.

Decred Journal – September 2018

Note: you can read this on GitHub (link), Medium (link) or old Reddit (link).

Development

Final version 1.3.0 of the core software was released bringing all the enhancements reported last month to the rest of the community. The groundwork for SPV (simplified payment verification) is complete, another reduction of fees is being deployed, and performance stepped up once again with a 50% reduction in startup time, 20% increased sync speed and more than 3x faster peer delivery of block headers (a key update for SPV). Decrediton's integrations of SPV and Politeia are open for testing by experienced users. Read the full release notes and get the downloads on GitHub. As always, don't forget to verify signatures.
dcrd: completed several steps towards multipeer downloads, improved introduction to the software in the main README, continued porting cleanups and refactoring from upstream btcd.
Currently in review are initial release of smart fee estimator and a change to UTXO set semantics. The latter is a large and important change that provides simpler handling, and resolves various issues with the previous approach. A lot of testing and careful review is needed so help is welcome.
Educational series for new Decred developers by @matheusd added two episodes: 02 Simnet Setup shows how to automate simnet management with tmux and 03 Miner Reward Invalidation explains block validity rules.
Finally, a pull request template with a list of checks was added to help guide the contributors to dcrd.
dcrwallet: bugfixes and RPC improvements to support desktop and mobile wallets.
Developers are welcome to comment on this idea to derive stakepool keys from the HD wallet seed. This would eliminate the need to backup and restore redeem scripts, thus greatly improving wallet UX. (missed in July issue)
Decrediton: bugfixes, refactoring to make the sync process more robust, new loading animations, design polishing.
Politeia: multiple improvements to the CLI client (security conscious users with more funds at risk might prefer CLI) and security hardening. A feature to deprecate or timeout proposals was identified as necessary for initial release and the work started. A privacy enhancement to not leak metadata of ticket holders was merged.
Android: update from @collins: "Second test release for dcrandroid is out. Major bugs have been fixed since last test. Latest code from SPV sync has been integrated. Once again, bug reports are welcome and issues can be opened on GitHub". Ask in #dev room for the APK to join testing.
A new security page was added that allows one to validate addresses and to sign/verify messages, similar to Decrediton's Security Center. Work on translations is beginning.
Overall the app is quite stable and accepting more testers. Next milestone is getting the test app on the app store.
iOS: the app started accepting testers last week. @macsleven: "the test version of Decred Wallet for iOS is available, we have a link for installing the app but the builds currently require your UDID. Contact either @macsleven or @raedah with your UDID if you would like to help test.".
Nearest goal is to make the app crash free.
Both mobile apps received new design themes.
dcrdata: v3.0 was released for mainnet! Highlights: charts, "merged debits" view, agendas page, Insight API support, side chain tracking, Go 1.11 support with module builds, numerous backend improvements. Full release notes here. This release featured 9 contributors and development lead @chappjc noted: "This collaboration with @raedahgroup on our own block explorer and web API for @decredproject has been super productive.".
Up next is supporting dynamic page widths site wide and deploying new visual blocks home page.
Trezor: proof of concept implementation for Trezor Model T firmware is in the works (previous work was for Model One).
Ticket splitting: updated to use Go modules and added simnet support, several fixes.
docs: beginner's guide overhaul, multiple fixes and cleanups.
decred.org: added 3rd party wallets, removed inactive PoW pools and removed web wallet.
@Richard-Red is building a curated list of Decred-related GitHub repositories.
Welcome to new people contributing for the first time: @klebe, @s_ben, @victorguedes, and PrimeDominus!
Dev activity stats for September: 219 active PRs, 197 commits, 28.7k added and 18.8k deleted lines spread across 6 repositories. Contributions came from 4-10 developers per repository. (chart)

Network

Hashrate: started and ended the month around 75 PH/s, hitting a low of 60.5 and a new high of 110 PH/s. BeePool is again the leader with their share varying between 23-54%, followed by F2Pool 13-30%, Coinmine 4-6% and Luxor 3-5%. As in previous months, there were multiple spikes of unidentified hashrate.
Staking: 30-day average ticket price is 98 DCR (+2.4). The price varied between 95.7 and 101.9 DCR. Locked DCR amount was 3.86-3.96 million DCR, or 45.7-46.5% of the supply.
Nodes: there are 201 public listening nodes and 325 normal nodes per dcred.eu. Version distribution: 5% are v1.4.0(pre) dev builds (+3%), 30% on v1.3.0 (+25%), 42% on v1.2.0 (-20%), 15% on v1.1.2 (-7%), 6% on v1.1.0. More than 76% of nodes run v1.2.0 and higher and therefore support client filters. Data as of Oct 1.

ASICs

Obelisk posted two updates on their mailing list. 70% of Batch 1 units are shipped, an extensive user guide is available, Obelisk Scanner application was released that allows one to automatically update firmware. First firmware update was released and bumped SC1 hashrate by 10-20%, added new pools and fixed multiple bugs. Next update will focus on DCR1. It is worth a special mention that the firmware source code is now open! Let us hope more manufacturers will follow this example.
A few details about Whatsminer surfaced this month. The manufacturer is MicroBT, also known as Bitwei and commonly misspelled as Bitewei. Pangolinminer is a reseller, and the model name is Whatsminer D1.
Bitmain has finally entered Decred ASIC space with their Antminer DR3. Hash rate is 7.8 TH/s while pulling 1410 W, at the price of $673. These specs mean it has the best GH/W and GH/USD of currently sold miners until the Whatsminer or others come out, although its GH/USD of 11.6 already competes with Whatsminer's 10.5. Discussed on Reddit and bitcointalk, unboxing video here.

Integrations

Meet our 17th voting service provider: decredvoting.com. It is operated by @david, has 2% fee and supports ticket splitting. Reddit thread is here.
For a historical note, the first VSP to support ticket splitting was decredbrasil.com:
@matheusd started tests on testnet several months ago. I contacted him so we could integrate with the pool in June this year. We set up the machine in July and bought the first split ticket on mainnet, using the decredbrasil pool, on July 19. It was voted on July 30. After this first vote on mainnet, we opened the tests to selected users (with more technical background) on the pool. In August we opened the tests to everyone, and would call people who want to join to the #ticket_splitting channel, or to our own Slack (in Portuguese, so mostly Brazilian users). We have 28 split tickets already voted, and 16 are live. So little more than 40 split tickets total were bought on decredbrasil pool. (@girino in #pos-voting)
KuCoin exchange listed DCBTC and DCETH pairs. To celebrate their anniversary they had a 99% trading fees discount on DCR pairs for 2 weeks.
Three more wallets integrated Decred in September:
ChangeNow announced Decred addition to their Android app that allows accountless swaps between 150+ assets.
Coinbase launched informational asset pages for top 50 coins by market cap, including Decred. First the pages started showing in the Coinbase app for a small group of testers, and later the web price dashboard went live.

Adoption

The birth of a Brazilian girl was registered on the Decred blockchain using OriginalMy, a blockchain proof of authenticity services provider. Read the full story in Portuguese and in English.

Marketing

Advertising report for September is ready. Next month the graphics for all the ads will be changing.
Marketing might seem quiet right now, but a ton is actually going on behind the scenes to put the right foundation in place for the future. Discovery data are being analyzed to generate a positioning strategy, as well as a messaging hierarchy that can guide how to talk about Decred. This will all be agreed upon via consensus of the community in the work channels, and materials will be distributed.
Next, work is being done to identify the right PR partner to help with media relations, media training, and coordination at events. While all of this is coming up to speed, we believe the website needs a refresher reflecting the soon to be agreed upon messaging, plus a more intuitive architecture to make it easier to navigate. (@Dustorf)

Events

Attended:
Upcoming:
We'll begin shortly reviewing conferences and events planned for the first half of 2019. Highlights are sure to include The North American Bitcoin Conference in Miami (Jan 16-18) and Consensus in NYC (May 14-16). If you have suggestions of events or conferences Decred should attend, please share them in #event_planning. In 2019, we would like to expand our presence in Europe, Asia, and South America, and we're looking for community members to help identify and staff those events. (@Dustorf)

#support is not often mentioned, but it must be noted that every day on this channel people get high quality support. (@bee: To my surprise, even those poor souls running Windows 10. My greatest respect to the support team!)

Markets

In September DCR was trading in the range of USD 34-45 / BTC 0.0054-0.0063. On Sep 6, DCR revisited the bottom of USD 34 / BTC 0.0054 when BTC quickly dropped from USD 7,300 to 6,400. On Sep 14, a small price rise coincided with both the start of KuCoin trading and hashrate spike to 104 PH/s. Looking at coinmarketcap charts, the trading volume is a bit lower than in July and August.
As of Oct 4, Decred is #18 by the number of daily transactions with 3,200 tx, and #9 by the USD value of daily issuance with $230k. (source: onchainfx)
Interesting observation by @ImacallyouJawdy: while we sit at 2018 price lows the amount locked in tickets is testing 2018 high.

Relevant External

ASIC for Lyra2REv2 was spotted on the web. Vertcoin team is preparing a new PoW algorithm. This would be the 3rd fork after two previous forks to change the algorithm in 2014 and 2015.
A report titled The Positive Externalities of Bitcoin Mining discusses the benefits of PoW mining that are often overlooked by the critics of its energy use.
A Brief Study of Cryptonetwork Forks by Alex Evans of Placeholder studies the behavior of users, developers and miners after the fork, and makes the cases that it is hard for child chains to attract users and developers from their parent chains.
New research on private atomic swaps: the paper "Anonymous Atomic Swaps Using Homomorphic Hashing" attempts to break the public link between two transactions. (bitcointalk, decred)
On Sep 18 Poloniex announced delisting of 8 more assets. That day they took a 12-80% dive showing their dependence on this one exchange.
Circle introduced USDC markets on Poloniex: "USDC is a fully collateralized US dollar stablecoin using the ERC-20 standard that provides detailed financial and operational transparency, operates within the regulated framework of US money transmission laws, and is reinforced by established banking partners and auditors.".
Coinbase announced new asset listing process and is accepting submissions on their listing portal. (decred)
The New York State Office of the Attorney General posted a study of 13 exchanges that contains many insights.
A critical vulnerability was discovered and fixed in Bitcoin Core. Few days later a full disclosure was posted revealing the severity of the bug. In a bitcointalk thread btcd was called 'amateur' despite not being vulnerable, and some Core developers voiced their concerns about multiple implementations. The Bitcoin Unlimited developer who found the bug shared his perspective in a blog post. Decred's vision so far is that more full node implementations is a strength, just like for any Internet protocol.

Check out Part 2 of our first Skycoin Official AMA with Synth

Enjoy Part 2 of 2 of the Skycoin Official AMA with Synth for March, 2018. Part 1 is posted here.
 
How will skywire stop centralization such as massive skywire node forwarding servers, like with the current internet?
There will be more competition between pools in Skycoin than there is in Bitcoin. If that problem occurs, then we will deal with it, we have strategies and models in place to handle this potential scenario.
 
How will it stop whales building humongous skyminer pools in massive cities such as New York that will forward all the nodes in that city?
If a whale wants to come in and invest 1 billion dollars, to take control of the internet service for a whole city, then it will only make Skycoin grow faster. If it becomes a problem like what is happening for Bitcoin right now, then we have plans in place to handle the issue.
The miner pools can only be so abusive in Skycoin, because if the pools are too abusive, then other people will switch to smaller pools that give them a better deal.
 
How do you solve mining for bandwidth? What is to stop an attacker putting two routers next to each other to print money?
This is of the reasons why Skycoin will work and we do not think we have any viable competitors. We know how to solve this problem.
The short answer is that we are not paying users for bandwidth. Users are paying each other. So if you put two routers next to each other in a loop, then you are paying yourself for your own bandwidth! So you are not printing money. It is the same as moving money from one of your wallets, to the other wallet.
Skycoin does not “print money”. There is zero inflation. It is a closed loop economy.
Our mathematical models show that if the network is not running in closed loop, that you can always game the system and eventually botnets will take over all of the rewards.
There is another way we found, which uses a bandwidth credit system and later we can build futures and derivatives markets. Since bandwidth is scarce, but is wasted if not used our algorithm allows a certain amount of fraud (acceptable loss ratio) to be factored in but mathematically guarantees that the fraud stays below a certain threshold. There is a maximum amount or upper bound a node can get away with, before it detected and the other nodes stop working with the node.
Basicly, eventually the nodes have a reputation system and nodes prefer other nodes who follow the rules over nodes that try to engage in bandwidth fraud.
We have a simple working solution for the testnet, then we will start building up the full solution, which will also improve the network performance a lot by directing most of the rewards at trustworthy nodes with a high uptime, lower latency and higher bandwidth capacity. The node reputation system will take a bit of work, but will allow us to do a lot of new thing with QoS and routing.
 
Since the people using Skywire resources depend on those resources to report what happens to the outside world, how do you stop adversarial actors from defrauding users using information asymmetry between the users and the blockchain? How do you do this without an enormous amount of overhead?
Adversarial actors are a major problem in any system where anything of value is concerned.
If you do not have a solution for fraud, then bots will come in and steal all the money. Imagine you are running a poker site with 100,000 humans on it. Then someone floods the poker site with 1 million bots (who are better at poker than humans). The bots are going to steal all the money from your users and they will leave (because they are only losing now and the game is not balanced anymore).
If you tell people “I will give you money for running this computer program”, there are people who control 15 million computers and they will just run the program on their botnet. All of the money will goto the bots.
Skywire solves the bot problem by a sort of peer-to-peer whitelisting protocol. We do not let people flood the network with bots. Each node maintains a peer list and if you want to peer a human has to add the peer on both ends by hand, so it’s harder for a botnet to come in and try to take over.
People, because they are social, will peer with people they know personally (their own social network or communities). It’s designed so that people with high quality, hand curated peer lists will have a significant advantage over someone who peers with 10 million slow botnet computers, running on laptops running windows XP. Also people who own dedicated hardware will also have much better performance metrics and will be rewarded more than botnet computers.
The overhead for the record keeping is only 2% to 6% of the total bandwidth in the network, depending on how long the sessions are and the specifics. So the overhead is at the same level as for the existing internet.
 
Why did you use Orange Pi’s, that have their NIC on a USB 2.0 bus, for the hardware in the Skynodes?
Ideally, for security, the NIC should not have DMA (Direct Memory Access). USB 3.0 is a nightmare. USB 2.0 is bad and USB 1.0 is actually better (more secure, but slower).
The NIC drivers or firmware usually have a lot of dangerous security problems.
We are designing a custom PCB and there are several security, cost, design issues that do not have a clear best solution. The NIC is on the USB 2.0 bus, primarily because that is what the chip supports and because of cost.
 
What is to stop the cable lobbyist and the FCC who have already proven they will go against the will of the people from banning skywire? Couldn't they stop people from getting access to the backhaul and outright outlaw the entire concept? When I asked on the Telegram everyone dismissed the concern and said 'its impossible to stop us, look at the darknet'. And while that is true, for skywire to work don't you need widespread normie adoption? What percentage of people would actually run this if they banned it?
There are many, extremely wealthy and powerful groups that are being squeezed out by the FCC and the internet monopolies. There are some surprising large and powerful players that will support (publicly or clandestinely) any project that gives them some breathing room from the telecom squeeze out.
We want them to try to ban Skywire. That means we are winning.
You have to understand the context of the FCC and the cable companies.
The cable companies were forced to be very aggressive and remove net neutrality and start using mafia extraction tactics against companies like Netflix and Google, because of earnings pressure. The cable companies all have declining revenue because people are using the internet for video and are “cord cutting”. The CEOs and management are desperate to keep their stock prices up and slow down the earnings decline.
The CEOs of the cable companies are under extreme pressure to increase earnings in the short term, but are using tactics that will create a lasting long term backlash. The CEOs will increase earnings, they will see their stock prices go up, they will cash out their options and retire to the Hamptons. The backlash will be the next CEOs problem.
Skywire is global and the FCC only matters in the US. In Europe there is much more diversity in ISPs and you wont see the type of battle and resistance they will put on in the US.
The cable companies are dying. They are the dinosaurs whining and moaning before the meteor impact. Fighting technology innovations like Skywire is part of the process of the demise of these telecom monopolies, but it is not something to worry about.
If they are attacking us, it means we are winning. We will be ready.
 
Do you have an estimate for when coin hours will have value and be tradable?
We are working on getting the exchange up, but it will need to wait until the testnet. First we will make coinhours tradable, then we will open them up for exchange.
 
How, in simple terms, do coin hours prevent spam?
The more they spam, the more scarce and expensive the coinhours become. If someone spams or attacks Skycoin, the Skycoin price will actually go up.
Since there are only a finite, scarce number of Skycoin and each Skycoin generates a fixed number of coinhours per hour; then coinhours become scarce and valuable. They put a price on transactions.
An attacker or spammer has to ask “Should I just sell my coinhours for money or should I spam and lose money?”. Eventually the spammer will use up all of his coinhours and then will have to buy them from someone else to keep spamming. Eventually they will even drive the market rate of the coinhours up, until the spamming becomes so expensive that they run out of money or give up.
 
On telegram you wrote coin hours are meant to be volatile if I'm not mistaken. Will this be a problem in the future?
It depends. By shuffling volatility from Skycoin, to the coin hours it makes Skycoin more valuable as a store of value and as a currency for transactions.
We want people to spend coin hours. If Skycoin is going up everyday 5% a day, why would you spend it? If we priced the bandwidth in Skycoin, the whole network would shutdown because everyone would just be hoarding their Skycoin instead of spending them! That is why we introduced coinhours.
Coinhours solve the problem of hoarding and gives people a currency which they are encouraged to spend. Skycoin is a better store of value because there is no inflation, while coinhours are better for transactions because they have an inflation rate that encourages people to spend them.
The market cap of the Skycoin coinhours could actually be higher than the market cap of Skycoin under some conditions.
Everyone is very excited to see what the price coinhours settle at. People are betting on the market and cannot wait to trade and speculate on the coinhours (either dumping them before they go down to zero, or hoarding them incase they go up 500x). I was surprised at how excited people are about the coinhours.
 
Are there any more coins launching on skyledger soon you can talk about?
Kittycash.com, mdl.life, SPACO, solarbankers.com, and more...
I have been so busy with Skycoin I cannot even keep up with the new ICOs.
We are opening up the platform now and more people will be launching coins that I could possible keep track of. We should probably have a registry to track the Skyledger ICOs.
 
Will it be easier to launch coins on skyledger in the future? Any other skyledger updates?
Yes. We have a script now for launching new coins!
In 30 seconds you will be able to: Create your coin Have your ICO software running to collect money Have the coin automatically listed on an internal exchange (instead of waiting 8 months to get listed on some mega exchange) Have mobile, desktop and hardware wallet support Skyledger is getting a rebranding and its own marketing team. We have several flagship coins in development, that will help alot for Skycoin marketing.
 
Synth mentioned months ago in the telegram chat that Obelisk was still in development, when and how will the algorithm be tested and release? How are the actual transactions validated if obelisk is not the algorithm used?
We have done several simulations. There are several peer reviewed academic research papers published about it. There are open source simulations in the github repo.
The exchanges are worried about us enabling the full consensus algorithm without enough testing. We have to do a lot of testing before we turn everything on.
Currently the exchanges forced us to use a masternode dev check-point system. Over time, we are going to make extensive changes to the node and keep minting on the checkpoint system, while rolling out everything. Then after extensive testing, will roll out everything in stages.
The testing of the new features and stages, needs to be done on a smaller coin (other Skyledger coins) before being rolled out to Skycoin. Skycoin’s market cap is too large and we have to be cautious about bugs and not rolling out new code before its tested.
The dev check-point system is a compromise that allows us to test new consensus algorithms, while protecting the exchanges. If the exchanges lose money from a bug and lose $200,000 in Skycoin then we have to pay them for the lose basicly.
The exchanges are all short-staffed because of massive user base growth. They are taking weeks sometimes to upgrade the Skycoin node version, after we release a new version. We have to carefully coordinate our release and upgrade schedules to minimize exchange downtimes.
The short answer, is; we can roll out everything in a few weeks (if we had to). Everything is tested and ready to go. However, because of the exchanges are overloaded, we have to roll it out carefully in planned stages, with a months notification for any changes.
I think everything will be in place by the end of the year, but the Skywire testnet is taking a lot of development resources, so we will push it back if that means Skywire gets launched faster.
Also, then we are always improving things. So even after it “done”, its not really done. It always need more developers working on it and improving everything. We think “one second transaction are fast enough”, then someone comes in with a video game they want to put on blockchain and suddenly we need 200 ms. The demands are endless.
When all of this work is done, it will also mean that we have the best blockchain platform. So we need to have a marketing event built around this. It may not make sense to do it in the middle of Skywire launch mania, because we can only handle so many things at once.
News like this, we also have to make sure we release it into an upward market, when a lot of people are paying attention to innovations in blockchain technology. It would be wasted if we released big news or features, when people were not paying attention.
 
What's in store for Skycoin this year?
To many things. Everything. All at once. Its crazy.
We are opening a hardware incubator, which is the most exciting thing for me. I think we will not see the real applications of blockchain until we get blockchain into the physical world.
 
Where do you see this project in 5 years, where in 10 years? (What is your long term goal?)
We are moving so fast. I could not imagine that we did as much as we have, in such a short time. I cannot even keep up with how many things are in development now.
The goal this year is to demonstrate real world applications of blockchain technology. To bring blockchain to the physical world and make it tangible.
The goal in five years is to make blockchain obsolete and to create what comes after blockchain. We are experimenting with a thing we have started to call the “Fibre”. I do not think innovation will stop at blockchain.
The third generation of coins is going to be post-blockchain and want to be a leader in this area.
 
How long before I can buy a coffee with Skycoin?
As soon as I buy a coffee shop, lol.
 
When the community try to bring more people to skycoin, specially those with big money, we have to face the fact that the time locked distribution is not auditable (or it is?) is there any strategy to calm the doubts about the distribution method (the developers hold the majority of the coins/ are the only ones able to mint coins)
One of the advantages of blockchain is that all of the transaction are public. So the distribution schedule is auditable. Skycoin’s distribution is completely public. The distribution addresses are also public. So it is very transparent.
There is an api endpoint here with the distribution addresses and information updated in real time https://explorer.skycoin.net//api/coinSupply
 
In your blogs you are talking about the possibility of a ninja announcement that burns 80% tokens. That means it will be only 20 mil sky. So, in which circumstances devs would do that?
If we can find a closed loop, economic model for Skywire, that does not require a 15 or 20 year distribution period. Then we will burn the coins. Then the distribution would be capped at 30 million instead of 100 million.
Right now, we need the coins held aside for infrastructure investment, to grow the network and maintain the project.
There are some future components, that could eliminate the need for infrastructure fund and enable the network to be self-financing. Even if we get these components in place, what it means is that the infrastructructure fund will just allow us to grow even faster! So we might still not burn the coins.
You cannot underestimate what it will mean if we are investing 100 million dollars a year of coins into growth. This is the fuel that drives the growth of the ecosystem, so it does not make sense to “burn” the fuel. If there are more projects we can invest in, to grow faster, then we should do that.
 
In your opinion, what is the best exchange for buying Skycoin right now, and why? And on what other exchanges will Skycoin be listed, and when?
C2CX is good. Cryptopia is also good but withdrawals are slow.
We will be listed on larger exchanges this year, but cannot give details. We signed contracts but the exchanges grew from 1 million users to 8 million users in a few months, so their technical teams are overloaded. Listing a new coin can take 6 months after signing the agreement now. We are doing all we can to expedite the process.
 
Will the Kittycash platform be advertised across cat loving forums and the like?
LOL.
 
What will the value of legendary kittys be in 2019?
People are spending 1 or 2 Bitcoin per legendary kitty now. Kitty Cash had to stop selling legendary kitties, because fifty people were trying to buy each kitty and too many people were trying to buy them at once.
 
When will SKY be listed on new exchanges?
We were listed on four new exchanges this month. Wolfcrypto, Next, and two other exchanges. I cannot even keep track of it.
We signed contracts with the largest exchanges, but are still waiting for technical integration and we signed contracts not to disclosure information about specific exchange listings.
The exchanges are very overloaded right now, with technical problems from user growth and also from hundreds of coin ICOs that all want to be listed at once. Millions of people per month are registering on the Bitcoin exchanges now and the exchanges are overloaded. It can be a six month waiting list for listing now, after contracts have been signed, so we are just waiting at this point. However, big exchanges are coming soon.
