The Blackmail Email Scam (part 6)

IF YOU RECEIVE A BLACKMAIL EMAIL, PLEASE REDACT THE PERSONAL INFORMATION AND POST IT AS A COMMENT ON THIS THREAD SO THAT OTHERS WHO RECEIVE THE SAME EMAIL CAN FIND IT THROUGH GOOGLE.

BLACKMAIL EMAIL SCAMS ARE ALSO SENT VIA SMS (TEXT) AND PHYSICAL MAIL. REGARDLESS OF THE METHOD, THEY ARE SPAM AND THE POST BELOW GIVES YOU INFORMATION AND ADVICE ABOUT WHAT TO DO.

There have been many recent posts about the blackmail email scam, so I have written this post and will keep it stickied until the posts about the scam die down. Blackmail email scams have that name because they started as an email spam campaign, however there have also been reports of these scams being sent via SMS and physical mail. If you are reading this because you have received one of these emails and you are worried, you can stop worrying. The blackmail email scam is a spam campaign that is sent out to thousands of addresses at a time. The threats are lies and you do not have anything to worry about. In many cases, the emails will contain some sort of privileged information about you such as your name, part or all of your phone number, and your password. The emails may also look like they were sent from your own email address. The data is gathered from data breaches, and if the email looks like it came from your account that is due to email spoofing. You can use the service Have I Been Pwned? to see if you are in any publicly known data breaches. If you receive an email that contains a password that you currently use, you should immediately change that. Current recommended password guidelines say that you should use a different, complex password for every account. You can generate and save passwords using a password manager for convenience. You should also be using two factor authentication using an app like Google Authenticator instead of receiving codes through SMS.
Here are some news articles about this scam. Here is a story from Brian Krebs, and here is a story from the New York Times.
Below are a few examples, but if you receive an email that is similar but not the same as the examples you see, that does not matter and does not mean that the email is real. The spammers constantly switch up their templates in order to bypass spam filters, so it's normal to receive an email that hasn't yet been posted online.

EXAMPLES

Hey, some time ago your computer was infected with my private malware, RAT (Remote Administration Tool).
I know at the time of infection your passwords was: xxxxxxxxxxx
My malware gave me full access to all your accounts, contacts and it also was possible to spy on you over your webcam.
Sometimes when I was bored I was spying on you, then once you started to SATISFYING YOURSELF!
At first I didn't knew how to react as I was shocked, then I decided to record you, I checked on google and found the software: Bandicam and it did the job.
After that I removed my malware to not leave any traces and this email was sent from some hacked account.
I can send the video of you to all your friends, contacts and publish it on social networks and the whole web.
You can stop me and only I can help you out in this situation.
Pay exactly 740$ in Bitcoin (BTC).
It's easy to buy Bitcoin (BTC), for example here: https://paxful.com/buy-bitcoin , https://www.buybitcoinworldwide.com/ , https://www.kraken.com/ , or google another exchanger.
My Bitcoin (BTC) wallet is: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Yes that's how the wallet looks like, copy and paste it, it's (cAsE-sEnSEtiVE)
I give you 3 days time to pay.
As I got access to this email account, I will know if this email has already been read, so the time is running.
After receiving the payment, I will remove the video and you can life your live in peace like before.
Learn from the mistake and update your browser before browsing the web next time!
I know XXXX is one of your password on day of hack..
Lets get directly to the point.
Not one person has paid me to check about you. You do not know me and you're probably thinking why you are getting this email?
in fact, i actually placed a malware on the adult vids (adult porn) website and you know what, you visited this site to experience fun (you know what i mean).
When you were viewing videos, your browser started out operating as a RDP having a key logger which provided me with accessibility to your display and web cam.
immediately after that, my malware obtained every one of your contacts from your Messenger, FB, as well as email account.
after that i created a double-screen video. 1st part shows the video you were viewing (you have a nice taste omg), and 2nd part displays the recording of your cam, and its you. Best solution would be to pay me $1004.
We are going to refer to it as a donation. in this situation, i most certainly will without delay remove your video.
My -BTC -address: 1GohL1jDz8BapZhohN2Xry6AKPq6PiJrjw [case SeNSiTiVe, copy & paste it]
You could go on your life like this never happened and you will not ever hear back again from me. You'll make the payment via Bitcoin (if you do not know this, search 'how to buy bitcoin' in Google).
if you are planning on going to the law, surely, this e-mail can not be traced back to me, because it's hacked too.
I have taken care of my actions. i am not looking to ask you for a lot, i simply want to be paid.
if i do not receive the bitcoin;, i definitely will send out your video recording to all of your contacts including friends and family, co-workers, and so on.
Nevertheless, if i do get paid, i will destroy the recording immediately.
If you need proof, reply with Yeah then i will send out your video recording to your 8 friends. it's a nonnegotiable offer and thus please don't waste mine time & yours by replying to this message.

Hello!
I'm the software engineer who hacked into your device's OS.
I've been observing you for months now. The thing is, you've been infected with malware through the adult website you visited.
In case you're not familiar with it, I'll explain. The Trojan infection gives me full access and control over your computer or any other device on your local. It means that I can see everything on your screen, turn on my camera and microphone, but you do not know about it.
I also have access to all your contacts, social networking data and all your correspondence.
Why didn't your antivirus detect any malware? A: My malware uses a driver, I update its signatures every 4 hours to keep your antivirus silent.
I have made a video showing how you satisfy yourself on the left side of the screen, and on the right side you see the video you have been watching. With one click, I can send this video to all your contacts in the email and social networks. I can also publish access to all your emails and messaging apps that you use.
If you want to prevent this, at that point: Transfer $400(USD) to my bitcoin wallet (if you do not know how to do it, then type in to Google: "Purchase a bitcoin").
My Bitcoin Wallet:1EGBGBptS9yKNPYYU9qUEoPNLptee8CEq9
After getting the payment, I will destroy the video and you won't hear from me again. I will provide you 50 hours (more than two days) to pay. I have a notice that you read this email and the timer started you opened it.
Don't attempt to answer me. It doesn't make any sense (the sender's address is generated by random). Filing a complaint somewhere doesn't make sense, because this email cannot be tracked, and neither can my bitcoin address. I don't make mistakes.
If I find that you shared this message with someone else, the video will be distributed immediately. Good luck with that.
And here are some common keywords used in the email so that this thread can be found by people Googling the email:

Zano Newcomers Introduction/FAQ - please read!

Welcome to the Zano Sticky Introduction/FAQ!

https://preview.redd.it/al1gy9t9v9q51.png?width=424&format=png&auto=webp&s=b29a60402d30576a4fd95f592b392fae202026ca
Hopefully any questions you have will be answered by the resources below, but if you have additional questions feel free to ask them in the comments. If you're quite technically-minded, the Zano whitepaper gives a thorough overview of Zano's design and its main features.
So, what is Zano? In brief, Zano is a project started by the original developers of CryptoNote. Coins with market caps totalling well over a billion dollars (Monero, Haven, Loki and countless others) run upon the codebase they created. Zano is a continuation of their efforts to create the "perfect money", and brings a wealth of enhancements to their original CryptoNote code.
Development happens at a lightning pace, as the Github activity shows, but Zano is still very much a work-in-progress. Let's cut right to it:
Here's why you should pay attention to Zano over the next 12-18 months. Quoting from a recent update:
Anton Sokolov has recently joined the Zano team. ... For the last months Anton has been working on theoretical work dedicated to log-size ring signatures. These signatures theoretically allows for a logarithmic relationship between the number of decoys and the size/performance of transactions. This means that we can set mixins at a level from up to 1000, keeping the reasonable size and processing speed of transactions. This will take Zano’s privacy to a whole new level, and we believe this technology will turn out to be groundbreaking!
If successful, this scheme will make Zano the most private, powerful and performant CryptoNote implementation on the planet. Bar none. A quantum leap in privacy with a minimal increase in resource usage. And if there's one team capable of pulling it off, it's this one.

What else makes Zano special?

You mean aside from having "the Godfather of CryptoNote" as the project lead? ;) Actually, the calibre of the developers/researchers at Zano probably is the project's single greatest strength. Drawing on years of experience, they've made careful design choices, optimizing performance with an asynchronous core architecture, and flexibility and extensibility with a modular code structure. This means that the developers are able to build and iterate fast, refining features and adding new ones at a rate that makes bigger and better-funded teams look sluggish at best.
Zano also has some unique features that set it apart from similar projects:
Privacy Firstly, if you're familiar with CryptoNote you won't be surprised that Zano transactions are private. The perfect money is fungible, and therefore must be untraceable. Bitcoin, for the most part, does little to hide your transaction data from unscrupulous observers. With Zano, privacy is the default.
The untraceability and unlinkability of Zano transactions come from its use of ring signatures and stealth addresses. What this means is that no outside observer is able to tell if two transactions were sent to the same address, and for each transaction there is a set of possible senders that make it impossible to determine who the real sender is.
Hybrid PoW-PoS consensus mechanism Zano achieves an optimal level of security by utilizing both Proof of Work and Proof of Stake for consensus. By combining the two systems, it mitigates their individual vulnerabilities (see 51% attack and "nothing at stake" problem). For an attack on Zano to have even a remote chance of success the attacker would have to obtain not only a majority of hashing power, but also a majority of the coins involved in staking. The system and its design considerations are discussed at length in the whitepaper.
Aliases Here's a stealth address: ZxDdULdxC7NRFYhCGdxkcTZoEGQoqvbZqcDHj5a7Gad8Y8wZKAGZZmVCUf9AvSPNMK68L8r8JfAfxP4z1GcFQVCS2Jb9wVzoe. I have a hard enough time remembering my phone number. Fortunately, Zano has an alias system that lets you register an address to a human-readable name. (@orsonj if you want to anonymously buy me a coffee)
Multisig
Multisignature (multisig) refers to requiring multiple keys to authorize a Zano transaction. It has a number of applications, such as dividing up responsibility for a single Zano wallet among multiple parties, or creating backups where loss of a single seed doesn't lead to loss of the wallet.
Multisig and escrow are key components of the planned Decentralized Marketplace (see below), so consideration was given to each of them from the design stages. Thus Zano's multisig, rather than being tagged on at the wallet-level as an afterthought, is part of its its core architecture being incorporated at the protocol level. This base-layer integration means months won't be spent in the future on complicated refactoring efforts in order to integrate multisig into a codebase that wasn't designed for it. Plus, it makes it far easier for third-party developers to include multisig (implemented correctly) in any Zano wallets and applications they create in the future.
(Double Deposit MAD) Escrow
With Zano's escrow service you can create fully customizable p2p contracts that are designed to, once signed by participants, enforce adherence to their conditions in such a way that no trusted third-party escrow agent is required.
https://preview.redd.it/jp4oghyhv9q51.png?width=1762&format=png&auto=webp&s=12a1e76f76f902ed328886283050e416db3838a5
The Particl project, aside from a couple of minor differences, uses an escrow scheme that works the same way, so I've borrowed the term they coined ("Double Deposit MAD Escrow") as I think it describes the scheme perfectly. The system requires participants to make additional deposits, which they will forfeit if there is any attempt to act in a way that breaches the terms of the contract. Full details can be found in the Escrow section of the whitepaper.
The usefulness of multisig and the escrow system may not seem obvious at first, but as mentioned before they'll form the backbone of Zano's Decentralized Marketplace service (described in the next section).

What does the future hold for Zano?

The planned upgrade to Zano's privacy, mentioned at the start, is obviously one of the most exciting things the team is working on, but it's not the only thing.
Zano Roadmap
Decentralized Marketplace
From the beginning, the Zano team's goal has been to create the perfect money. And money can't just be some vehicle for speculative investment, money must be used. To that end, the team have created a set of tools to make it as simple as possible for Zano to be integrated into eCommerce platforms. Zano's API’s and plugins are easy to use, allowing even those with very little coding experience to use them in their E-commerce-related ventures. The culmination of this effort will be a full Decentralized Anonymous Marketplace built on top of the Zano blockchain. Rather than being accessed via the wallet, it will act more as a service - Marketplace as a Service (MAAS) - for anyone who wishes to use it. The inclusion of a simple "snippet" of code into a website is all that's needed to become part a global decentralized, trustless and private E-commerce network.
Atomic Swaps
Just as Zano's marketplace will allow you to transact without needing to trust your counterparty, atomic swaps will let you to easily convert between Zano and other cyryptocurrencies without having to trust a third-party service such as a centralized exchange. On top of that, it will also lead to the way to Zano's inclusion in the many decentralized exchange (DEX) services that have emerged in recent years.

Where can I buy Zano?

Zano's currently listed on the following exchanges:
https://coinmarketcap.com/currencies/zano/markets/
It goes without saying, neither I nor the Zano team work for any of the exchanges or can vouch for their reliability. Use at your own risk and never leave coins on a centralized exchange for longer than necessary. Your keys, your coins!
If you have any old graphics cards lying around(both AMD & NVIDIA), then Zano is also mineable through its unique ProgPowZ algorithm. Here's a guide on how to get started.
Once you have some Zano, you can safely store it in one of the desktop or mobile wallets (available for all major platforms).

How can I support Zano?

Zano has no marketing department, which is why this post has been written by some guy and not the "Chief Growth Engineer @ Zano Enterprises". The hard part is already done: there's a team of world class developers and researchers gathered here. But, at least at the current prices, the team's funds are enough to cover the cost of development and little more. So the job of publicizing the project falls to the community. If you have any experience in community building/growth hacking at another cryptocurrency or open source project, or if you're a Zano holder who would like to ensure the project's long-term success by helping to spread the word, then send me a pm. We need to get organized.
Researchers and developers are also very welcome. Working at the cutting edge of mathematics and cryptography means Zano provides challenging and rewarding work for anyone in those fields. Please contact the project's Community Manager u/Jed_T if you're interested in joining the team.

Have you ever gotten into legal trouble by exploring the dark places of the internet? Like, "sorry, officer, I was only surfing drug markets and child molester forums for my next journalism piece..." Do you worry about that? Do you have to take extra steps to protect yourself? I'm very careful not to go anywhere that it is illegal to visit. You will hear loads of stories about how easy it is to "stumble upon" child porn, but the fact is that those sites usually have names like "Preteen cuties" so you know exactly what they are, and in order to access them you have to register. So you have to make a very deliberate choice to log into them. I have no interest whatsoever in viewing any child abuse material, so I don't go into those places. When I was researching The Darkest Web, I went to the discussion forums that didn't allow any images (though they did link to sites that did), and even there I turned off images.
As for the drugs, weapons etc, there is nothing illegal about surfing them and looking around.
I do get a bit nervous every time I visit the US, especially when I was invited to a "friendly" lunch with Homeland Security once (it was reasonably friendly as it turns out, it was also terrifying)

Why did homeland security want to talk to you? They said it was about the murder-for-hire stuff, but some of the questions leaned toward something else
Is there anything that really concerns you about the dark web? Some of the things already discussed are beyond barbaric and that is only the stuff that has been found out about and been picked up by the media and your fantastic work. Do you think the public should expect worse and more horrific revelations from the dark web or is it just "more of the same" for lack of a better term and do you think the authorities are getting better in shutting this inhumanity down and catching the people responsible? I am definitely not against people taking back their online privacy and I actually think that buying drugs from the darknet markets is a safer and more sensible option than buying them from the dodgy dealer down the road. However the one thing that is really disturbing is that the dark web has provided a place for child predators to find each other and form communities where they support and egg each other on. Imagine a few years ago, someone who was into hurtcore could never tell anyone else and would be unlikely to ever come across another person with the same perversions. Now it is as simple as finding the relevant site on the dark web. When there are suddenly hundreds of people who all think and act in the same way, it normlalizes what they are doing.
One of the guys who got caught, Matthew Falder, was a sadist who used to crowdsource "ideas" for torturing the children and teens he was blackmailing into doing heinous things for him online. But apparently he was a "normal" intelligent popular guy
the below is a reply to the above
But how does everyone participate in those illegal sites without getting caught? You said in other comments that you tried to stay away from underaged sites because they were illegal. Can't they be tracked down, even with tor and a vpn? The thing that I don't understand is that even on the dark web people say you should stay away from illegal sites, but how are pedos not getting caught? they are getting caught, but the way they are getting caught is through painstaking detective work, looking for clues in photos, befriending them online and getting them to reveal things about themselves (what is known as social engineering). It takes a long time and many resources.
I say don't go there because (a) it is illegal and (b) you really shouldn't want to go there
Iirc you attended the trial of the person behind the horrific hurt core website that was exposed a few years back. I was wondering if there was anything in particular that happened during the trial that particularly shocked or horrified you that isn't really public knowledge or talked about? Reactions from the judge or perpetrator during the trial etc. As I remember it the guy was a fairly young loner who lived with his parents but would probably never have been expected to be behind the horrific vile things which he was found to be. Also, how did you get into investigative journalism/writing? I wrote in one of the other replies above about the little mute girl that has stayed with me. Also, at the insistence of the prosecution, the judge had to watch "Daisy's Destruction" which was a video of torture of a toddler. He put it off for two days and when he came back he was white. He didn't have the sound on, which is considered the worst part, but he still looked shell-shocked. I don't envy him.
I'll cut'n'paste re your last question: I was in London, working for one of the most conservative law firms in the world when the Global Financial Crisis hit. I liked the job but it struck me when people were losing their livelihoods that I was working for the bad guys. I'd always wanted to be a writer so when I came back to Australia I quit law and enrolled in a writing course planning to be a novelist, but I discovered I was better at journalism. I first wrote for newspapers here about Silk Road and it grew from there
the below is a reply to the above
Thanks for the reply.. that really must've been horrific for all involved from investigation to trial and for all of the victims (apart from the scum responsible of course). I guess it would be naive to assume that the end of this site did anything other than drive this depraved community even further underground. That is the part which is really scary to me but I suppose all we can do is have faith that the authorities are always close on the tail. Thank you for your work on reporting on this and raising this stuff more into the public consciousness and making people more aware of what kind of evil still lurks. It was the most disturbing two days of my life, made all the worse because they read out hours of interactions from the site where the children still had not been identified or the predators caught.
Hurt2theCore was not the last site of its kind and there are still hurtcore sites to this day on the dark web. The one hopeful thing is that there are international task forces that seem to work together really well (unlike when it comes to drugs and every law enforcement agency wants to take the lead and they all withhold info from each other). There are a lot of resources allocated to identifying predators and their victims. Sometimes this has involved some very controversial tactics, such as taking over the sites and letting them run, so that they can use social engineering techniques to identify those who are using the sites and who are actually abusing children
the below is another reply to the original answer
So daisy's destruction is real? Was it referred to by that name court? I always thought it was a myth Yes, Daisy's Destruction is real, it was referred to by name in court and the judge had to watch the 12 minutes of it that were hosted on Hurt2theCore.
The "myth" part is that it shows a murder. The toddler, Daisy, lived, though she suffered such horrific injuries she will never be able to bear children. Hopefully she was young enough that she will grow up without the memory.
However, Scully did murder at least one child, whose body was found under the floorboards of his house. it is not known whether he filmed her murder as no video evidence of it has come to light.
the below is a reply to the above
Thanks for answering. I actually watched a really good video on Hurt2theCore on youtube once, I think it was by a guy called Nexpo. It was really detailed and informative about the whole case - I forgot those details. Thanks again for replying, this AMA is really informative! I think I recall that one, it was from a few years ago.
An excellent podcast that came out recently is "Hunting Warhead", highly recommend a listen. It is a tough listen, but exceptionally well-told and respectfully handled
How do you detach yourself from your work? I'm an investigator for a law firm and I've had a lot of difficult working on wrongful death cases recently. Also, how did you first end up getting published? Any tips for people interested in that field? Thanks! I don't detach. When I was researching hurtcore, it was harrowing and affected me deeply. Writing that part of the book was a very slow process because I just couldn't be in that headspace for very long at a time. Once the book was written I didn't go back there.
I already had a reputation as a blogger and a freelance journalist when i pitched my book on Silk Road. I got an agent and it was auctioned off, with Pan MacMillan getting the rights. At the time, Silk Road was still going strong, and the book I wrote was about this new frontier of drug dealing that was changing the world. I was writing it "from the inside" as I had been an active part of the community for two years. However, right as I submitted the final manuscript to my publisher, Silk Road was busted and Ross Ulbricht arrested, so i had to quickly change the narrative to a "Rise and Fall" thing!
How many times have you approached law enforcement with information and how many times has the approach resulted in action? and... are there times where you know something nefarious is happening but history and the evidence at hand tells you it's not worth the effort? There is no point in approaching law enforcement to say "I have come across this site". If I've found it, you can guarantee law enforcement has found it as well.
The only time I've approached law enforcement was when I had information that they did not, which was when a friendly hacker provided me with a back door into the Besa Mafia murder-for-hire site. I got to see all the messages and orders etc. Of course LE knew about the site, but they did not have the details of the people who had hits taken out on them. We tried desperately to tell police in several countries that real people had paid real money to have other real people killed, but they just weren't interested. We sounded like crazy people talking about dark web hitmen, who were scams anyway and nobody was dead, so why should they be interested? They became much more engaged when one of the people WE HAD PREVIOUSLY TOLD THEM ABOUT later turned up dead
the below is a reply to the above
By law enforcement, do you mean only local or else the big agencies? I feel like I wouldn't tell my local police department because they wouldn't really know what to do. It would have to the the bigger agencies. FBI in US. NCA in UK. AFP in Australia. Nobody was very interested, although the FBI did visit at least one of the targets to let her know she was a target. She still wound up dead
What are some of the most prevalent uses of the dark web that AREN'T all shady and nefarious? We might be getting into semantics here, but people use Tor, which is the most possible darknet that is used to access the dark web, just for private browsing and ensuring that commercial interests aren't following them everywhere to bombard them with ads for some thing they looked up.
Some of the news organizations have a dark web presence so that whistleblowers can upload information safely. Even the CIA has a site on the dark web so that people can anonymously tip off matters of national security.
Other than that, there are just forums, where you don't have to worry that every single stupid thing you post will be saved in posterity forever, to be trotted out years later when you run for congress or something
After everything you've seen, does anything surprise you anymore or are you just numb to it at this point? Do you think there should be more education/exposure about the dark web than there is now or would that just be counter-productive as people would just find another place to hide? I'm curious to hear any favourite stories about the Psychonauts. I am not numb and I hope I never become numb. I really don't visit the horrible dark places very often, unless I'm researching something specific, and even then I don't look at pictures or videos. Most of the crime is pretty benign - I'm not fazed by people wanting a safer way to buy drugs.
I think there needs to be ongoing discussions about online activity and its misuse in general, but most crime still happens on the clearnet. The dark web is not nearly as large or prevalent as people fear.
For a long time, a dealer provided free LSD to anyone who wanted it for personal use (ie not sale) and to any organizations who were doing psychedelic therapy.
One psychonaut got busted and spent time in prison... only he still had bitcoin in a wallet and by the time he was released he was a millionaire. He would have just spent it on drugs otherwise :)
I know law enforcement has to delve into the predator side of the dark web. With what you've seen do you think it should be mandatory or an industry standard that law enforcement officials seek professional help? I couldn't imagine investigating that daily and not thinking less of humanity at some point. I'm pretty sure they do. I worked for Legal Aid for a while, and i know there were pretty strict rules in place for the lawyers who had to defend child abusers.
When I was at the trial for Lux, owner of Hurt2theCore, I met a cop whose job it was to watch all the videos and befriend the predators in an attempt to get them to slip up and reveal something of themselves. She said she had a little filing cabinet in her brain where she put all that stuff, and that making an arrest made it all worthwhile. She had made several arrests personally. She was a sex offender's worst nightmare :)
What’s one of your personal favorite investigations and what made it unique for you? By far the Besa Mafia murder-for-hire case. What made it unique was that, first, I was provided a back door into the Besa Mafia site by a friendly hacker, so i had information that nobody else had. But then I became "friends" for want of a better word with the owner of the site, Yura. Besa Mafia, of course, was not killing anyone, but Yura made a LOT of money scamming would-be murderers out of their money. We entered into a weird relationship over the years where i would report on his activities and he would try every trick under the sun to stop me from doing so, so that he could keep scamming people. He even offered me a job, helping him, because he had become so busy. He also provided me with names and details of people who had hits taken out on them so I could pass them on to law enforcement.
It all became horribly real when one of the people who had a hit put out of them wound up dead. It wasn't Yura of course, but the guy had paid him $13K before giving up on the site and doing it himself. The thing was WE HAD TOLD THE FBI about the hit and the $13K and they visited the victim, but then put it into the too-hard basket when she couldn't think who might have paid that much to kill her.
the below is a reply to the above
Wow. That’s actually pretty cool. Reminds me of an old saying. “Keep your friends close, but your enemies closer.” It's a seriously bizarre relationship. When I was hired as a consultant by CBS for a 48 Hours expose on dark web hitmen, he actually agreed to meet me in London. But he thought that CBS was going to advertise his site as the real deal and he got excited and sent them details of two people who had hits put out on them. CBS sent them straight to the police and very shortly after two arrests were made and it was all over the news, where they called his site a scam. Yura got so pissed about it, he never turned up to our meeting. They had even hired an Academy Award-nominated master of disguise makeup artist to disguise him!
are "red rooms" actually a prevalent thing, or just a widespread misconception or rumor? I ask in part because it's very easy to see, for instance, Mexican cartels dismembering people alive, etc, just on the clearnet. Hell, a couple days ago I saw a video posted of a cartel member cutting out a dude's heart while the guy was alive, and he ATE it. He fucking ATE it. So it seems plausible... The most popular myth of all is Red Rooms, where people – usually women – are tortured to death live on camera while those who have paid to watch type in torture commands in a chat box. Think the movie Hostel, with webcams. In this sense these have never been proven to exist. I get where you are coming from with the cartels, and the recent news item where they found those shipping containers set up with torture rooms freaked me out and made me wonder!
There is some truth to this rumour, but the execution is not like you see in the movies. Most notably, because it involves children, not adults abused on demand for paying pedophiles, but not to the point of death
the below is a reply to the above
The news about those shipping containers really made me speculate, since for every one person who gets caught doing something evil, there must be at least several more people who are very honed in their 'profession' doing the same evil deeds and worse, yet who evade being captured for decades. Anyway, based on morbid things I've seen, karma comes around eventually... I know, right? It really freaked me out, and then when I read that they already had intended victims for them but the police got to them first and put them in protected custody.. IMAGINE SEEING THOSE PICTURES AND KNOWING YOU WERE SUPPOSED TO BE IN THEM!! I would retire to a deserted island somewhere
the below is a reply to the above
Your line of work could easily result in something like C-PTSD down the road a little ways. I have a morbid curiosity, and have seen worse than those shipping containers had to offer. I'm sure you have as well. So one more question from you, if you don't mind: what are some proactive approaches to mental health you take to safeguard your sanity? A lot of wine. Cuddle my dog
Hi, there! This has been fascinating to read; thank you so much for sharing! I'm curious: why do you think so many people who don't want to engage with disgusting and illegal content like hurtcore find it so interesting to read about? Do you have any insight into your readership and the ethics associated with reading about these kind of topics? I think morbid fascination with the dark is exceedingly common - just look at how many people can't get enough about serial killers! In some ways it is probably a self-defense mechanism - the vast majority of true-crime readers are women. People like to be armed with knowledge. We also like to be spooked and scared.
As for my books, I don't really go into much gory detail, but the horror still shines through
Out of all 9-5 jobs out there, why this? What’s your motive? I got disenchanted by being a lawyer and I had wanted to be an author since childhood. The lawyering put me in a strong enough financial position that I could quit to do a uni course for a couple of years. My plan was to become a best-selling novelist, but my first chick-lit novel was nothing special. However, during the course, I found I did really well at journalism and was soon making a living as a freelance journo before I finished the course. My first major feature was on the Silk Road drugs market, which I had discovered thanks to a friend who was using it. Once I got in there I became fascinated by everything about it and started contacting the owner, users, vendors etc asking for stories (I was upfront about who I was). I began the first serious dark web blog - allthingsvice.com - and also became the go-to freelancer for Australian dark web stories. Then I pitched my first book and got a healthy advance for it.
I like working for myself, working from home and delving into things. Right now I have my dream job (though it wouldn't hurt to pay a bit more. I'm certainly not making anywhere near what I used to make lawyering, but I make enough to get by and I live pretty simply)
Did you ever do any writing on Brian Farrell and his role in Silk Road 2.0? I was Brian's cellmate for all of 2017 at Sheridan Federal Prison and heard all of his crazy stories. Was just curious as to the validity of them all. DoctorClu! I did write briefly about him in Silk Road, but it wasn't all positive. I remember being frustrated by the shitshow that was Silk Road 2.0 in the beginning, right after SR1 shut and when DPR2 took off and Defcon got all dramatic. It settled down after a bit and lasted a year, when it was revealed THEY HAD A FUCKING UNDERCOVER HOMELAND SECURITY OFFICER ON STAFF THE WHOLE TIME. But yeah, anyhow, they are probably true. I'd love to hear them :)
Was there ever something on the dark web that made you surprised ( in a good way) and smile ? So many things. Back in the day of the original Silk Road, I became obsessed with the forums, the people behind it, the intelligent discourse about the War on Drugs and philosophy. I found it amusing that drug dealers ran sales and giveaways. There were book clubs and movie clubs.
One of the most important people from that era was Dr Fernando Cauevilla, who became a member of Silk Road as "DoctorX". He was a real doctor who provided genuine, free, non-judgmental advice about drug use to the members of the site. It was quite an amazing time.

Did Ulbricht get taken down the way we were told in the news? What happened to all the Bitcoins? His arrest went down the way we were told in the news. How they located the server has never been disclosed (other than a fanciful explanation that NOBODY could believe). This explanation may be tested if Variety Jones runs a Fourth Amendment argument at his trial
The bitcoin in the wallet on Ross' computer was auctioned off by the Feds. He may have other bitcoin wallets stashed somewhere but nobody knows
the below is another reply to the original answer
Book/movie clubs on the silk road? Yeah, they would set reading and then everyone would come back and discuss the book, or they would have a time when everyone watched the same movie at the same time and chatted about it in real time
the below is a reply to the above
Haha that's amazing! I don't suppose you remember any of the books in question? They used to be a lot of philosophy books, especially on agorism. A Lodging of Wayfaring Men was one of the books. I remember V for Vendetta on a movie night
You don't seem to be pushing your most recent project and you're actually answering all the questions people ask, so I've got ask...are you some sort of government plant meant to destabilize reddit? This isn't how AMAs are supposed to work. You come in, you half ass a few questions, hawk whatever you're here to hawk, and then leave after 20 minutes. That's how it's done. lol I'm a genuine redditor from way back, and I love talking about the stuff I do. I did find that after I answered a question in an AskReddit thread a while back that blew up, the sales followed. But that was organic and I don't think you can force it to happen - Reddit can spot that a mile awy
What are some of the best things about the dark web? And can anyone get on it? Things you can buy that you can’t buy normally online? I really enjoy some of the forums, especially the psychonaut forums where people who like to trip on psychedelics get together and talk drugs and philosophy. There's a real "be kind to one another" vibe.
Getting on the dark web is easy, but not getting scammed when buying things takes a lot of homework. Yes, you can buy most things, but the most popular things are drugs and digital goods, i.e. things that depend on repeat custom and are easily transferable from seller to buyer
the below is a reply to the question
[deleted] You're doing the Good Work my man. I'd give you one of those awards if i knew how
What would you define the word "Safe" when it come to the internet (both www and dark web) world and are there any tips that I should follow to keep myself safe? It really depends on what YOU mean by safe. Tor, which is the darknet that provides access to the dark web will keep you safe from prying eyes and surveillance.
If you mean keep your information safe, the old-fashioned advice is to never reuse your password and to enable 2-Factor authentication wherever you can. Your information is quite likely somewhere on the dark web thanks to high-profile hacks of major organizations, but provided you don't re-use usernames and passwords, you really don't have to worry too much about it.
If you mean keeping yourself and/or any kid safe from predators, the only thing is to ensure you are educated about the approaches and methods they use.
Has Covid affected the Dark Web in any real way? Also I just read through all of the post comments, what incredible story’s. I would totally buy a book about the Silk Road or Yaru! re covid on the dark web, here's some notes I made for an interview I did recently:
* when Trump first hyped hydroxychloroquine as a potential miracle cure for COVID-19, drug dealers on the dark web seized on the claim.
* Listings quickly popped up on the most popular darknet markets
* A vendor on Whitehouse Market sells 100 Pills for $90, calling it a “Miracle Drug For Coronavirus” and suggesting buyers purchase in bulk to sell at a mark-up locally.
* Another makes the dubious claim “This drug will help people to beat Corona Virus” There are 11 listings on Empire Market currently, although more than half are from the one seller, who is a well-known and trusted vendor on the site.
* There were also people claiming to be selling infected blood or plasma of recovered COVID victims
* The infected blood stuff is just bullshit IMO Just because something is listed doesn’t mean it is genuinely for sale
* There's been some claims to be selling vaccines
* At the beginning there were also loads of listings for PPE
* some just used it as a marketing tactic - “fight off the virus with edible cannabis” or “relax with Xanax” and others as an excuse to raise their prices
* However, sales are low compared to sales of other drugs on the site, so it is difficult to say whether it’s something that will really catch on
* It didn’t take long for complaints to come in and market owners to clamp down on anything claiming to be a miracle cure or vaccine
* users were discouraging other users from profiting off the pandemic and requested markets provide health and safety information
* All the major markets forbid anything being sold as a cure for COVID. They flagged keywords and vendors would be told to take any listings down. They also put out PSAs telling people not to buy
* Monopoly: threatened to ban and.. “You are about to ingest drugs from a stranger on the internet - under no circumstances should you trust any vendor that is using COVID-19 as a marketing tool to peddle already questionable goods”
* It was a business decision. They don’t want anything that will attract attention or that might cause desperate people who wouldn’t normally use the DNMs to find their way there
* The idea behind DNMs generally is educated and responsible drug use. They really don’t want people dying - bad publicity and no repeat custom
* However the dark web is rife with scammers and people willing to prey on the desperate so there are still scams out there
* The only way I could ever see it becoming a thing is if there is a well-known potential cure/vaccine that is not being made widely available and could plausibly find its way onto the black market
Hi Eileen :) My question is about how you construct your Casefile episodes - I assume there is an extensive amount of outlining but do you write the final draft like a script specifically thinking about his voice? And about how long are they as far as - for example - does one hour equal 50-60 pages? Thank you. I initially write them as if I'm writing an article or book, but then go back and edit them to be read out and yes, when I do that, I do have his voice in my head lol. One episode is usually around 12,000 words. It then goes to another editor who edits the episode to be even more "casefileaa' before it finally goes to Casey
Have you been exposed to things in your investigations that have made you second-guess what you do? If so, what has made you keep going back? i've definitely had days where I question everything, but to be honest, I don't really hang around the horrible really dark places much. I did delve into the child predator forums when I was writing The Darkest Web, but I don't make it a habit to go there. The psychonauts are much more friendly
the below is a reply to the above
To continue with that- have you clicked images, links that make you a suspect in certain scenarios? Oh absolutely. Sometimes I go to a "Fresh Onion" site, which is a site that crawls all the .onion addresses (dark web URLs end in .onion rather than .com, org etc) and alerts you to any new ones. Sometimes they don't have any description, so you take a big risk clicking on any of those. The most dangerous button on the dark web is the "Random Onion" button, so I avoid that.
I'm pretty careful about what I click, but the moment something looks questionable I nope the fuck right out of there
the below is a reply to the above
Have you ever felt that you may be a suspect whether it be ok a drug site, a pedo site, etc. Have you ever been contacted by someone regarding your surfing habits? Well my actual surfing habits are protected by Tor, which means they are hidden from prying eyes, so no I haven't been contacted about them. I am very open on the dark web about who I am and what I'm doing there - I use the name OzFreelancer on all of the markets and forums. I don't go to the sites that host child abuse images - you can't un-see that shit and I don't need it in my head.
As noted in another reply, I was contacted by Homeland Security on one of my visits to the US and taken for a "friendly" lunch.
the below is another reply to the original answer
Psychonauts are more friendly than most people. Something about regular mind altering experiences makes you want to be less of a cunt. Yeah, I call The Majestic Garden a little corner of sunshine and rainbows on the dark web :)
the below is a reply to the above
More about The Majestic Garden please? What is grown there? It's a place where people talk about and source psychedelics - most notably LSD, the 2C family, DMT and MDMA. Talk about and sourcing harder drugs is forbidden. In fact the admins snuck in an autocorrect so that any time someone wrote the word "cocaine" it would post as "a raging hardon" :D
Do you fear that seeing all this stuff might turn you emotionally blunt? I'm not watching any of this stuff on purpose (even the clearnet stuff), because I fear that the more you see of it, the more normal it gets, and ultimately, the more it will fuck you up. To quote the movie 8mm... "If you dance with the devil, the devil don't change. The devil changes you." No, I can't even watch "3 Guys 1 Hammer" in its entirety, let alone look at the really dark materials on the dark web. When I was researching The Darkest Web, going into the predator forums did the opposite of making me blunt. It was the shortest section of the book but took the longest to write because it was so emotionally draining
the below is a reply to the above
I have to ask, what is "3 Guys 1 Hammer"? It's a video of two teenagers murdering an innocent man with a hammer that went viral on the gore sites of the regular internet. It's truly horrible.
The teens killed over 20 people. I wrote about them in my book Psycho.com (excuse the plug)
I heard somewhere that you foster dogs. Is that something you do to counter all the terrible humans you encounter in your research - everyone knows how dogs are better than people. How many dogs have you fostered and which one was your favourite? After my dog died I knew I didn't want to have another dog as I wanted to travel more. So I thought fostering dogs would be the answer as you give them love for a few weeks and then they go to their forever home. My first foster, Roy, was a big fat failure and now he lives here and sleeps in our bed and is the most spoiled dog alive
the below is a reply to the above
Did you then just decide to quit travelling? I don't know anything about Roy, but I already think I love him. Nah, he has family he can stay with when I go away, but any major travelling has been thwarted by COVID for now anyway. I'm in a hard lockdown city.
And I'm sure Roy would love you too, u/suckmyhugedong
Given how much you know about the dark web, what kind of crazy awful nightmares have you had? This could be a really good one. Thank you Probably the worst thing was delving into the forums where child predators gathered. I never looked at any videos or photos, but just seeing their discussions sickened me. The one thing that keeps coming back to me came out of the sentencing hearing that I attended of Lux, owner of Hurt2theCore, considered the most heinous website in history. In court they read out a conversation between him and an abuser who made videos of torture of the mute disabled child in his care. They were joking "at least she won't be able to tell anyone" . the abuser wasn't caught, at least by that stage
As an indie author, how have you sourced freelancers? Did you seek out those that have specific expertise or did you work with editors from your time as a traditionally published author? I learned to do everything myself before I started outsourcing.
I work with a professional editor who happens to be a friend of mine from back when we did a writing course together. I've been doing my own covers, but now that I have some royalties coming in, I've engaged a professional cover artist from Reedsy to develop a brand and more professional-looking covers for me. It is the hardest thing to find people you really want to work with and who are in budget.
I still haven't got the hang of email lists, newsletters or a website - they are all in a total mess at the moment and I'd love to find someone who can do them, but again it is that problem of finding the right person who is within budget
is it true that most of the internet is in the "dark web"? if so about how much percent is it? By far the biggest myth is that it 10x larger than the Internet. I mean, this should be common sense anyway, but it gets propagated by tabloid media all the time. It stems a lot from people using the terms "deep web" and "dark web" interchangably when they are different things.
The statement that 90% (or thereabouts) of the internet is hidden is true, and it is called the deep web (not the dark web). The 90% that is hidden is all those pages you won’t get to using google or any other search engines. There’s nothing scary about that – in fact it works in your favour.
The easiest example is your bank. The bank’s major page is available to anyone who searches the web (part of the 10%, also known as the “clearweb”). But once you log in, all those pages you can access that contain your personal details? Not searchable on google. Each one of those pages is part of the 90% of the deep web. Business and government intranets also make up part of the deep web. Honestly, it’s nothing to worry about.
The dark web – the hidden services available through Tor and other anonymising programs – makes up a tiny fraction of the deep web. A really, really tiny fraction. It is infinitely smaller than the clearweb.
Do you think human trafficking happens on the dark web? Last year (I think) there was a really bizarre story here in the UK about a model who was supposedly kidnapped to order, drugged and transported overseas by a group called "Black Death". The official story is that BD doesn't exist, and the kidnapper was a fantasist. Is it likely that humans are bought and sold into slavery over the dark web? There are no slick websites with auctions for slaves on the dark web, but I have no doubt that human traffickers use dark web encryption to communicate.
(here comes the second plug for the thread) - I wrote about the kidnap of Chloe Ayling and the Black Death Group in Murder on the Dark Web
What ever happened to the plural of mongoose storyline? it seems like after he was arrested in the united states, his case just fizzled away. did you ever find out any more information about yuri after he cancelled the interview with a news program? what happened with peter scully's case? i read that there was a fire where a lot of evidence against him was held and it all went up in smoke. are there any character and/or personality storylines that you feel haven't been told or are still a complete mystery? eg. tony76 1. He is still in the MCC in NY and awaiting trial. It has taken a long time because he had terrabytes of information to go through and things would have slowed down due to covid. I understand he is running the Fouth Amendment argument that Ulbricht probably should have run in the first place
2. I last heard from Yura just a few weeks ago. He is still scamming. There are some more programs in the works about him
3. Yes there was a very convenient fire, but he still got sentenced to life and i hope he rots in hell
4. I am madly curious to know what is happening with the extradition of James Ellingson, aka “MarijuanaIsMyMuse”, aka "redandwhite", MAYBE aka Tony76. I would LOVE to know that full story!
the below is a reply to the above
Wow, this shit is a blast from the past. I used to love following the darknetmarket drama. Did you write about PoM and tony76 in one of your books? Ever since reddit shut down /darknetmarket I've been out of the loop. Yes, I wrote about them in The Darkest Web
I was in touch with PoM/Mongoose when he went on a posting rampage on MyPlanetGanja, then visited him in Bangkok prison several times. Wrote all about it :)
This may have been answered by a previous post pertaining to native language barriers to specific sites on the dark web, but in your investigations, did you come across content/pages/forums from warzones? Middle East, Burma, Afghanistan, etc? If yes, what was the most memorable bit? There are loads of sites in foreign languages, but it is too difficult for me (a one-language numpty) to attempt to translate through AI, and it is not worth hiring a translator when they could just turn out to be Cat Facts

Best Cryptocurrency Multi-Exchange Trading and Portfolio Management Platforms Ranking 2020

Best Cryptocurrency Multi-Exchange Trading and Portfolio Management Platforms Ranking 2020
Trade on multiple exchanges from a single platform and avoid the hassle of multiple logins, different interfaces, constant tab changing and overall keeping track of balance holdings and trades.
https://preview.redd.it/ksar6fkxmfv51.jpg?width=1200&format=pjpg&auto=webp&s=b8629b0f29aefd9546d816413cc82de9656ef7f9
With more than 300 cryptocurrency exchanges today, most traders have to manage multiple exchange accounts.
The need for more than one account usually rises because of the variety of offered crypto currency pairs, market liquidity, having to diversify the risk of being hacked, as well as the different trading tools and terms each exchange offers.
Trading and keeping track of your portfolios on multiple exchanges is time consuming, inefficient and frustrating. Having to log on different platforms, use different interfaces, keeping track of multiple portfolios and all trading related activities become increasingly difficult with each new account.
It would be simple and easy if you could connect all those exchange accounts into a single multi-exchange platform which combines all the data in real time and provides a single interface to control all remote exchange accounts.

Multi-exchange platforms

A multi-exchange platform allows the traders to connect all their exchange accounts into a single account through the user of API keys generated from the account of each exchange.
Once all accounts are connected into a single one, using the exchanges interfaces becomes obsolete. The unified account will now track and combine all portfolios and traders will be able to track prices, order statuses and other data across all exchange accounts from a single interface.
In addition, most multi-exchange platforms provide various information tools such as news aggregators, sentiment tools, arbitrage matrix and price alerts.
With regards to API keys security, these platforms do not require withdrawal or deposit permissions which limits the possibility of fraud and loss of funds.
Finally, multi-exchange platforms do not typically charge additional trading fees and do not require lengthy verification procedures.

The current top platforms

HOW TO MANAGE AND STORE YOUR CRYPTO: CRYPTO WALLETS – By Mickael Mosse

Since Bitcoin is a relative new topic and not everybody looks to invest in cryptocurrencies, for most it remains a theoretical matter of our modern world. But to make cryptocurrencies a reality closer to our daily lives than we believe, I’d like to talk about crypto wallets.
A crypto wallet is the specific tool that allow anyone who owns cryptocurrencies to access them and make use of them in the real world. As the word says, a crypto wallet has the function to store and make available our crypto. However, more than storing our crypto -which is completely digital -, crypto wallets hold the private keys that protect and authorize access to the digital coins.
Whoever controls the private keys controls the crypto attached to those keys. This is why one of the main steps to owning crypto: choosing the right wallet for you. A crypto wallet manages the private keys for you and, for that reason, the coins you possess. But not all wallets are made the same. In the market it exists several types of crypto wallet. It can be an app, a website, or a physical device that manages the private keys for you. The main thing to consider when choosing a wallet is level of safety they offer in the management of your private keys.
While with hardware wallets you have total control of your private keys, online wallets are the ones who have control over your keys. Wallet apps also allow you to have complete access to your keys but having to depend on devices connected to the internet make them more vulnerable to hackers than a hardware wallet but are more safe than online wallets, which are the most prone to these attacks. The digital aspect of cryptocurrency makes the need to be connected to the internet in order to have access to your coins. Of course, there will always be people trying to take advantage to any weaknesses existent. Not only hackers you have to be aware of, but shady applications that claim to be crypto wallets to just have access to your private keys. As easy to wanting to download an app from Playstore or Apple store, you unknowingly be leaded to possibility of a hack.
Also, you have to be aware that crypto exchanges are not wallets. Some of them offer to store your private keys, and although they’re safe exchanges, they don’t specialize in the storage of keys. The most famous case of crypto loss due to this is the case of Mt. Gox. People placed their trust in this exchange for storing their private keys and billions of dollars in Bitcoins were irrecoverable. Even if you choose the safest wallet by your own terms, you can lose the keys, which are a series of numbers of letters, if you don’t have a backup. People have the option to rely even on a piece of paper to store their private key, as long as it remains out of destructive elements. Remember that the private keys protect your assets in crypto but, if you are not careful, you can be locked out from ever seeing them again.
So it’s good your considering all the pros and cons of investing in crypto and how much it would serve your own interest, but crypto wallets are another not-so-known aspect that require a good amount of investment in time and searching about. Although this article is by far a guideline to choose a crypto wallet, I hope it is a good start, and an awakening one, to your searching quest and your plans to make owning crypto a reality.

Submitted for consideration to The Great Reddit Scaling Bake-Off
Baked by the pastry chefs at Offchain Labs
Please send questions or comments to [[email protected] ](mailto:[email protected])
1. Overview
We're excited to submit Arbitrum Rollup for consideration to The Great Reddit Scaling Bake-Off. Arbitrum Rollup is the only Ethereum scaling solution that supports arbitrary smart contracts without compromising on Ethereum's security or adding points of centralization. For Reddit, this means that Arbitrum can not only scale the minting and transfer of Community Points, but it can foster a creative ecosystem built around Reddit Community Points enabling points to be used in a wide variety of third party applications. That's right -- you can have your cake and eat it too!
Arbitrum Rollup isn't just Ethereum-style. Its Layer 2 transactions are byte-for-byte identical to Ethereum, which means Ethereum users can continue to use their existing addresses and wallets, and Ethereum developers can continue to use their favorite toolchains and development environments out-of-the-box with Arbitrum. Coupling Arbitrum’s tooling-compatibility with its trustless asset interoperability, Reddit not only can scale but can onboard the entire Ethereum community at no cost by giving them the same experience they already know and love (well, certainly know).
To benchmark how Arbitrum can scale Reddit Community Points, we launched the Reddit contracts on an Arbitrum Rollup chain. Since Arbitrum provides full Solidity support, we didn't have to rewrite the Reddit contracts or try to mimic their functionality using an unfamiliar paradigm. Nope, none of that. We launched the Reddit contracts unmodified on Arbitrum Rollup complete with support for minting and distributing points. Like every Arbitrum Rollup chain, the chain included a bridge interface in which users can transfer Community Points or any other asset between the L1 and L2 chains. Arbitrum Rollup chains also support dynamic contract loading, which would allow third-party developers to launch custom ecosystem apps that integrate with Community Points on the very same chain that runs the Reddit contracts.
1.1 Why Ethereum
Perhaps the most exciting benefit of distributing Community Points using a blockchain is the ability to seamlessly port points to other applications and use them in a wide variety of contexts. Applications may include simple transfers such as a restaurant that allows Redditors to spend points on drinks. Or it may include complex smart contracts -- such as placing Community Points as a wager for a multiparty game or as collateral in a financial contract.
The common denominator between all of the fun uses of Reddit points is that it needs a thriving ecosystem of both users and developers, and the Ethereum blockchain is perhaps the only smart contract platform with significant adoption today. While many Layer 1 blockchains boast lower cost or higher throughput than the Ethereum blockchain, more often than not, these attributes mask the reality of little usage, weaker security, or both.
Perhaps another platform with significant usage will rise in the future. But today, Ethereum captures the mindshare of the blockchain community, and for Community Points to provide the most utility, the Ethereum blockchain is the natural choice.
1.2 Why Arbitrum
While Ethereum's ecosystem is unmatched, the reality is that fees are high and capacity is too low to support the scale of Reddit Community Points. Enter Arbitrum. Arbitrum Rollup provides all of the ecosystem benefits of Ethereum, but with orders of magnitude more capacity and at a fraction of the cost of native Ethereum smart contracts. And most of all, we don't change the experience from users. They continue to use the same wallets, addresses, languages, and tools.
Arbitrum Rollup is not the only solution that can scale payments, but it is the only developed solution that can scale both payments and arbitrary smart contracts trustlessly, which means that third party users can build highly scalable add-on apps that can be used without withdrawing money from the Rollup chain. If you believe that Reddit users will want to use their Community Points in smart contracts--and we believe they will--then it makes the most sense to choose a single scaling solution that can support the entire ecosystem, eliminating friction for users.
We view being able to run smart contracts in the same scaling solution as fundamentally critical since if there's significant demand in running smart contracts from Reddit's ecosystem, this would be a load on Ethereum and would itself require a scaling solution. Moreover, having different scaling solutions for the minting/distribution/spending of points and for third party apps would be burdensome for users as they'd have to constantly shuffle their Points back and forth.
2. Arbitrum at a glance
Arbitrum Rollup has a unique value proposition as it offers a combination of features that no other scaling solution achieves. Here we highlight its core attributes.
Decentralized. Arbitrum Rollup is as decentralized as Ethereum. Unlike some other Layer 2 scaling projects, Arbitrum Rollup doesn't have any centralized components or centralized operators who can censor users or delay transactions. Even in non-custodial systems, centralized components provide a risk as the operators are generally incentivized to increase their profit by extracting rent from users often in ways that severely degrade user experience. Even if centralized operators are altruistic, centralized components are subject to hacking, coercion, and potential liability.
Massive Scaling. Arbitrum achieves order of magnitude scaling over Ethereum's L1 smart contracts. Our software currently supports 453 transactions-per-second for basic transactions (at 1616 Ethereum gas per tx). We have a lot of room left to optimize (e.g. aggregating signatures), and over the next several months capacity will increase significantly. As described in detail below, Arbitrum can easily support and surpass Reddit's anticipated initial load, and its capacity will continue to improve as Reddit's capacity needs grow.
Low cost. The cost of running Arbitrum Rollup is quite low compared to L1 Ethereum and other scaling solutions such as those based on zero-knowledge proofs. Layer 2 fees are low, fixed, and predictable and should not be overly burdensome for Reddit to cover. Nobody needs to use special equipment or high-end machines. Arbitrum requires validators, which is a permissionless role that can be run on any reasonable on-line machine. Although anybody can act as a validator, in order to protect against a “tragedy of the commons” and make sure reputable validators are participating, we support a notion of “invited validators” that are compensated for their costs. In general, users pay (low) fees to cover the invited validators’ costs, but we imagine that Reddit may cover this cost for its users. See more on the costs and validator options below.
Ethereum Developer Experience. Not only does Arbitrum support EVM smart contracts, but the developer experience is identical to that of L1 Ethereum contracts and fully compatible with Ethereum tooling. Developers can port existing Solidity apps or write new ones using their favorite and familiar toolchains (e.g. Truffle, Buidler). There are no new languages or coding paradigms to learn.
Ethereum wallet compatibility. Just as in Ethereum, Arbitrum users need only hold keys, but do not have to store any coin history or additional data to protect or access their funds. Since Arbitrum transactions are semantically identical to Ethereum L1 transactions, existing Ethereum users can use their existing Ethereum keys with their existing wallet software such as Metamask.
Token interoperability. Users can easily transfer their ETH, ERC-20 and ERC-721 tokens between Ethereum and the Arbitrum Rollup chain. As we explain in detail below, it is possible to mint tokens in L2 that can subsequently be withdrawn and recognized by the L1 token contract.
Fast finality. Transactions complete with the same finality time as Ethereum L1 (and it's possible to get faster finality guarantees by trading away trust assumptions; see the Arbitrum Rollup whitepaper for details).
Non-custodial. Arbitrum Rollup is a non-custodial scaling solution, so users control their funds/points and neither Reddit nor anyone else can ever access or revoke points held by users.
Censorship Resistant. Since it's completely decentralized, and the Arbitrum protocol guarantees progress trustlessly, Arbitrum Rollup is just as censorship-proof as Ethereum.
Block explorer. The Arbitrum Rollup block explorer allows users to view and analyze transactions on the Rollup chain.
Limitations
Although this is a bake-off, we're not going to sugar coat anything. Arbitrum Rollup, like any Optimistic Rollup protocol, does have one limitation, and that's the delay on withdrawals.
As for the concrete length of the delay, we've done a good deal of internal modeling and have blogged about this as well. Our current modeling suggests a 3-hour delay is sufficient (but as discussed in the linked post there is a tradeoff space between the length of the challenge period and the size of the validators’ deposit).
Note that this doesn't mean that the chain is delayed for three hours. Arbitrum Rollup supports pipelining of execution, which means that validators can keep building new states even while previous ones are “in the pipeline” for confirmation. As the challenge delays expire for each update, a new state will be confirmed (read more about this here).
So activity and progress on the chain are not delayed by the challenge period. The only thing that's delayed is the consummation of withdrawals. Recall though that any single honest validator knows immediately (at the speed of L1 finality) which state updates are correct and can guarantee that they will eventually be confirmed, so once a valid withdrawal has been requested on-chain, every honest party knows that the withdrawal will definitely happen. There's a natural place here for a liquidity market in which a validator (or someone who trusts a validator) can provide withdrawal loans for a small interest fee. This is a no-risk business for them as they know which withdrawals will be confirmed (and can force their confirmation trustlessly no matter what anyone else does) but are just waiting for on-chain finality.
3. The recipe: How Arbitrum Rollup works
For a description of the technical components of Arbitrum Rollup and how they interact to create a highly scalable protocol with a developer experience that is identical to Ethereum, please refer to the following documents:
Arbitrum Rollup Whitepaper
Arbitrum academic paper (describes a previous version of Arbitrum)
4. Developer docs and APIs
For full details about how to set up and interact with an Arbitrum Rollup chain or validator, please refer to our developer docs, which can be found at https://developer.offchainlabs.com/.
Note that the Arbitrum version described on that site is older and will soon be replaced by the version we are entering in Reddit Bake-Off, which is still undergoing internal testing before public release.
5. Who are the validators?
As with any Layer 2 protocol, advancing the protocol correctly requires at least one validator (sometimes called block producers) that is honest and available. A natural question is: who are the validators?
Recall that the validator set for an Arbitrum chain is open and permissionless; anyone can start or stop validating at will. (A useful analogy is to full nodes on an L1 chain.) But we understand that even though anyone can participate, Reddit may want to guarantee that highly reputable nodes are validating their chain. Reddit may choose to validate the chain themselves and/or hire third-party validators.To this end, we have begun building a marketplace for validator-for-hire services so that dapp developers can outsource validation services to reputable nodes with high up-time. We've announced a partnership in which Chainlink nodes will provide Arbitrum validation services, and we expect to announce more partnerships shortly with other blockchain infrastructure providers.
Although there is no requirement that validators are paid, Arbitrum’s economic model tracks validators’ costs (e.g. amount of computation and storage) and can charge small fees on user transactions, using a gas-type system, to cover those costs. Alternatively, a single party such as Reddit can agree to cover the costs of invited validators.
6. Reddit Contract Support
Since Arbitrum contracts and transactions are byte-for-byte compatible with Ethereum, supporting the Reddit contracts is as simple as launching them on an Arbitrum chain.
Minting. Arbitrum Rollup supports hybrid L1/L2 tokens which can be minted in L2 and then withdrawn onto the L1. An L1 contract at address A can make a special call to the EthBridge which deploys a "buddy contract" to the same address A on an Arbitrum chain. Since it's deployed at the same address, users can know that the L2 contract is the authorized "buddy" of the L1 contract on the Arbitrum chain.
For minting, the L1 contract is a standard ERC-20 contract which mints and burns tokens when requested by the L2 contract. It is paired with an ERC-20 contract in L2 which mints tokens based on whatever programmer provided minting facility is desired and burns tokens when they are withdrawn from the rollup chain. Given this base infrastructure, Arbitrum can support any smart contract based method for minting tokens in L2, and indeed we directly support Reddit's signature/claim based minting in L2.
Batch minting. What's better than a mint cookie? A whole batch! In addition to supporting Reddit’s current minting/claiming scheme, we built a second minting design, which we believe outperforms the signature/claim system in many scenarios.
In the current system, Reddit periodically issues signed statements to users, who then take those statements to the blockchain to claim their tokens. An alternative approach would have Reddit directly submit the list of users/amounts to the blockchain and distribute the tokens to the users without the signature/claim process.
To optimize the cost efficiency of this approach, we designed an application-specific compression scheme to minimize the size of the batch distribution list. We analyzed the data from Reddit's previous distributions and found that the data is highly compressible since token amounts are small and repeated, and addresses appear multiple times. Our function groups transactions by size, and replaces previously-seen addresses with a shorter index value. We wrote client code to compress the data, wrote a Solidity decompressing function, and integrated that function into Reddit’s contract running on Arbitrum.
When we ran the compression function on the previous Reddit distribution data, we found that we could compress batched minting data down to to 11.8 bytes per minting event (averaged over a 6-month trace of Reddit’s historical token grants)compared with roughly 174 bytes of on-chain data needed for the signature claim approach to minting (roughly 43 for an RLP-encoded null transaction + 65 for Reddit's signature + 65 for the user's signature + roughly 8 for the number of Points) .
The relative benefit of the two approaches with respect to on-chain call data cost depends on the percentage of users that will actually claim their tokens on chain. With the above figures, batch minting will be cheaper if roughly 5% of users redeem their claims. We stress that our compression scheme is not Arbitrum-specific and would be beneficial in any general-purpose smart contract platform.
8. Benchmarks and costs
In this section, we give the full costs of operating the Reddit contracts on an Arbitrum Rollup chain including the L1 gas costs for the Rollup chain, the costs of computation and storage for the L2 validators as well as the capital lockup requirements for staking.
Arbitrum Rollup is still on testnet, so we did not run mainnet benchmarks. Instead, we measured the L1 gas cost and L2 workload for Reddit operations on Arbitrum and calculated the total cost assuming current Ethereum gas prices. As noted below in detail, our measurements do not assume that Arbitrum is consuming the entire capacity of Ethereum. We will present the details of our model now, but for full transparency you can also play around with it yourself and adjust the parameters, by copying the spreadsheet found here.
Our cost model is based on measurements of Reddit’s contracts, running unmodified (except for the addition of a batch minting function) on Arbitrum Rollup on top of Ethereum.
On the distribution of transactions and frequency of assertions. Reddit's instructions specify the following minimum parameters that submissions should support:
Over a 5 day period, your scaling PoC should be able to handle:
  • 100,000 point claims (minting & distributing points)
  • 25,000 subscriptions
  • 75,000 one-off points burning
  • 100,000 transfers
We provide the full costs of operating an Arbitrum Rollup chain with this usage under the assumption that tokens are minted or granted to users in batches, but other transactions are uniformly distributed over the 5 day period. Unlike some other submissions, we do not make unrealistic assumptions that all operations can be submitted in enormous batches. We assume that batch minting is done in batches that use only a few percent on an L1 block’s gas, and that other operations come in evenly over time and are submitted in batches, with one batch every five minutes to keep latency reasonable. (Users are probably already waiting for L1 finality, which takes at least that long to achieve.)
We note that assuming that there are only 300,000 transactions that arrive uniformly over the 5 day period will make our benchmark numbers lower, but we believe that this will reflect the true cost of running the system. To see why, say that batches are submitted every five minutes (20 L1 blocks) and there's a fixed overhead of c bytes of calldata per batch, the cost of which will get amortized over all transactions executed in that batch. Assume that each individual transaction adds a marginal cost of t. Lastly assume the capacity of the scaling system is high enough that it can support all of Reddit's 300,000 transactions within a single 20-block batch (i.e. that there is more than c + 300,000*t byes of calldata available in 20 blocks).
Consider what happens if c, the per-batch overhead, is large (which it is in some systems, but not in Arbitrum). In the scenario that transactions actually arrive at the system's capacity and each batch is full, then c gets amortized over 300,000 transactions. But if we assume that the system is not running at capacity--and only receives 300,000 transactions arriving uniformly over 5 days-- then each 20-block assertion will contain about 200 transactions, and thus each transaction will pay a nontrivial cost due to c.
We are aware that other proposals presented scaling numbers assuming that 300,000 transactions arrived at maximum capacity and was executed in a single mega-transaction, but according to our estimates, for at least one such report, this led to a reported gas price that was 2-3 orders of magnitude lower than it would have been assuming uniform arrival. We make more realistic batching assumptions, and we believe Arbitrum compares well when batch sizes are realistic.
Our model. Our cost model includes several sources of cost:
  • L1 gas costs: This is the cost of posting transactions as calldata on the L1 chain, as well as the overhead associated with each batch of transactions, and the L1 cost of settling transactions in the Arbitrum protocol.
  • Validator’s staking costs: In normal operation, one validator will need to be staked. The stake is assumed to be 0.2% of the total value of the chain (which is assumed to be $1 per user who is eligible to claim points). The cost of staking is the interest that could be earned on the money if it were not staked.
  • Validator computation and storage: Every validator must do computation to track the chain’s processing of transactions, and must maintain storage to keep track of the contracts’ EVM storage. The cost of computation and storage are estimated based on measurements, with the dollar cost of resources based on Amazon Web Services pricing.
It’s clear from our modeling that the predominant cost is for L1 calldata. This will probably be true for any plausible rollup-based system.
Our model also shows that Arbitrum can scale to workloads much larger than Reddit’s nominal workload, without exhausting L1 or L2 resources. The scaling bottleneck will ultimately be calldata on the L1 chain. We believe that cost could be reduced substantially if necessary by clever encoding of data. (In our design any compression / decompression of L2 transaction calldata would be done by client software and L2 programs, never by an L1 contract.)
9. Status of Arbitrum Rollup
Arbitrum Rollup is live on Ethereum testnet. All of the code written to date including everything included in the Reddit demo is open source and permissively licensed under the Apache V2 license. The first testnet version of Arbitrum Rollup was released on testnet in February. Our current internal version, which we used to benchmark the Reddit contracts, will be released soon and will be a major upgrade.
Both the Arbitrum design as well as the implementation are heavily audited by independent third parties. The Arbitrum academic paper was published at USENIX Security, a top-tier peer-reviewed academic venue. For the Arbitrum software, we have engaged Trail of Bits for a security audit, which is currently ongoing, and we are committed to have a clean report before launching on Ethereum mainnet.
10. Reddit Universe Arbitrum Rollup Chain
The benchmarks described in this document were all measured using the latest internal build of our software. When we release the new software upgrade publicly we will launch a Reddit Universe Arbitrum Rollup chain as a public demo, which will contain the Reddit contracts as well as a Uniswap instance and a Connext Hub, demonstrating how Community Points can be integrated into third party apps. We will also allow members of the public to dynamically launch ecosystem contracts. We at Offchain Labs will cover the validating costs for the Reddit Universe public demo.
If the folks at Reddit would like to evaluate our software prior to our public demo, please email us at [email protected] and we'd be more than happy to provide early access.
11. Even more scaling: Arbitrum Sidechains
Rollups are an excellent approach to scaling, and we are excited about Arbitrum Rollup which far surpasses Reddit's scaling needs. But looking forward to Reddit's eventual goal of supporting hundreds of millions of users, there will likely come a time when Reddit needs more scaling than any Rollup protocol can provide.
While Rollups greatly reduce costs, they don't break the linear barrier. That is, all transactions have an on-chain footprint (because all calldata must be posted on-chain), albeit a far smaller one than on native Ethereum, and the L1 limitations end up being the bottleneck for capacity and cost. Since Ethereum has limited capacity, this linear use of on-chain resources means that costs will eventually increase superlinearly with traffic.
The good news is that we at Offchain Labs have a solution in our roadmap that can satisfy this extreme-scaling setting as well: Arbitrum AnyTrust Sidechains. Arbitrum Sidechains are similar to Arbitrum Rollup, but deviate in that they name a permissioned set of validators. When a chain’s validators agree off-chain, they can greatly reduce the on-chain footprint of the protocol and require almost no data to be put on-chain. When validators can't reach unanimous agreement off-chain, the protocol reverts to Arbitrum Rollup. Technically, Arbitrum Sidechains can be viewed as a hybrid between state channels and Rollup, switching back and forth as necessary, and combining the performance and cost that state channels can achieve in the optimistic case, with the robustness of Rollup in other cases. The core technical challenge is how to switch seamlessly between modes and how to guarantee that security is maintained throughout.
Arbitrum Sidechains break through this linear barrier, while still maintaining a high level of security and decentralization. Arbitrum Sidechains provide the AnyTrust guarantee, which says that as long as any one validator is honest and available (even if you don't know which one will be), the L2 chain is guaranteed to execute correctly according to its code and guaranteed to make progress. Unlike in a state channel, offchain progress does not require unanimous consent, and liveness is preserved as long as there is a single honest validator.
Note that the trust model for Arbitrum Sidechains is much stronger than for typical BFT-style chains which introduce a consensus "voting" protocols among a small permissioned group of validators. BFT-based protocols require a supermajority (more than 2/3) of validators to agree. In Arbitrum Sidechains, by contrast, all you need is a single honest validator to achieve guaranteed correctness and progress. Notice that in Arbitrum adding validators strictly increases security since the AnyTrust guarantee provides correctness as long as any one validator is honest and available. By contrast, in BFT-style protocols, adding nodes can be dangerous as a coalition of dishonest nodes can break the protocol.
Like Arbitrum Rollup, the developer and user experiences for Arbitrum Sidechains will be identical to that of Ethereum. Reddit would be able to choose a large and diverse set of validators, and all that they would need to guarantee to break through the scaling barrier is that a single one of them will remain honest.
We hope to have Arbitrum Sidechains in production in early 2021, and thus when Reddit reaches the scale that surpasses the capacity of Rollups, Arbitrum Sidechains will be waiting and ready to help.
While the idea to switch between channels and Rollup to get the best of both worlds is conceptually simple, getting the details right and making sure that the switch does not introduce any attack vectors is highly non-trivial and has been the subject of years of our research (indeed, we were working on this design for years before the term Rollup was even coined).
12. How Arbitrum compares
We include a comparison to several other categories as well as specific projects when appropriate. and explain why we believe that Arbitrum is best suited for Reddit's purposes. We focus our attention on other Ethereum projects.
Payment only Rollups. Compared to Arbitrum Rollup, ZK-Rollups and other Rollups that only support token transfers have several disadvantages:
  • As outlined throughout the proposal, we believe that the entire draw of Ethereum is in its rich smart contracts support which is simply not achievable with today's zero-knowledge proof technology. Indeed, scaling with a ZK-Rollup will add friction to the deployment of smart contracts that interact with Community Points as users will have to withdraw their coins from the ZK-Rollup and transfer them to a smart contract system (like Arbitrum). The community will be best served if Reddit builds on a platform that has built-in, frictionless smart-contract support.
  • All other Rollup protocols of which we are aware employ a centralized operator. While it's true that users retain custody of their coins, the centralized operator can often profit from censoring, reordering, or delaying transactions. A common misconception is that since they're non-custodial protocols, a centralized sequencer does not pose a risk but this is incorrect as the sequencer can wreak havoc or shake down users for side payments without directly stealing funds.
  • Sidechain type protocols can eliminate some of these issues, but they are not trustless. Instead, they require trust in some quorum of a committee, often requiring two-third of the committee to be honest, compared to rollup protocols like Arbitrum that require only a single honest party. In addition, not all sidechain type protocols have committees that are diverse, or even non-centralized, in practice.
  • Plasma-style protocols have a centralized operator and do not support general smart contracts.
13. Concluding Remarks
While it's ultimately up to the judges’ palate, we believe that Arbitrum Rollup is the bakeoff choice that Reddit kneads. We far surpass Reddit's specified workload requirement at present, have much room to optimize Arbitrum Rollup in the near term, and have a clear path to get Reddit to hundreds of millions of users. Furthermore, we are the only project that gives developers and users the identical interface as the Ethereum blockchain and is fully interoperable and tooling-compatible, and we do this all without any new trust assumptions or centralized components.
But no matter how the cookie crumbles, we're glad to have participated in this bake-off and we thank you for your consideration.
