one or other type of device, in the Google Authenticator world you have just lost your access completely. So, it’s up to the service you are using to determine a recovery mechanism. What’s interesting is that some services don’t give you one. Others offer recovery via email, SMS, or other similar mechanism which then introduces the same issue. We, therefore, believe in recovery via time lock, where your account is locked for a period of time before you can reset it. BM: In the meantime, are there ways to prevent users from losing their password in the first place? PP: There is some psychology involved here. Part of our philosophy at EdgeSecure is to carefully align technology with humanity. This involves a recognition of the fact that we’re all fallible beings, that we do forget passwords. One step we employ to help people not forget passwords is to ask them to voluntarily enter it from time-to-time when they go to access their app. Our intent is to give them the opportunity to change it if they forget it at that moment. BM: How exactly does this work? PP: We have an algorithm inside of the app that has what we call a reminder “step off,” based on users actually entering it. This “step off” is how frequently we remind you based on how many times you’ve actually entered the password in the past. Obviously, you can get into the app with a pin, thumbprint and now facial ID. But if you lose that device, the password is the only way to get back on. BM: This seems like an idea that other tech solution providers will likely want to pick up on.PP: No doubt. We fashion ourselves as the world’s only password recovery for encrypted data. While that, in and of itself, is a patentable idea, we’ve opted to not patent, in the name of open source, open collaborative effort. BM: What sort of criticism do you hear from the crypto community? PP: One of the main ones we get is that we are not as secure as a hardware wallet. These criticisms come from people that often harbor the biggest fears of something that I have yet to see happen, namely, a person losing crypto from a device attack. Sure, you might hear of publications espousing theoretical exploits. But I haven’t seen evidence of a mass exploit with cryptocurrency taken on a device with encrypted data. Yet there are millions, if not billions, of dollars being poured into solutions for that problem. BM: Aren’t hardware wallets a great resource then for those who have these concerns? PP: They can be. But it’s important to keep in mind that with hardware wallets, the attack vector isn’t someone getting into it digitally over the internet. Rather, the attack vector is the individual user. I can’t count the number of people who say to me after purchasing a hardware wallet, “Now, I’m secure!” I then ask them, what did you do with the backup information? Often they’ll say, “I put it on Google Drive.” My response: “You did what? That’s the worst thing you could possibly do with the private key.” BM: Finally, what are your thoughts regarding security vulnerabilities among centralized exchanges? PP: It’s a big concern, no doubt. Coinbase is obviously the most recognizable example in the crypto world, but I don’t think that their model can survive long term. I’d describe them as a $15 billion piñata for hackers. Yes, they haven’t been hacked and I believe a combination of luck and skill has prevented that from occurring. BM: So do you believe that it’s just a matter of time before a serious hack occurs?PP: Let me say this. One of the hardest aspects of centralized security is that it doesn’t scale. In other words, the bigger you get, the harder it is for you to secure. And as the pot becomes bigger, you have to hire and entrust more and more people inside the company. So it takes just one bad apple with access and there goes a lot of user money. BM: Where do you see this security space headed? PP: In the next

3–5 years, we should actually see a trend where users will seek out what I call Edge-secured apps, where people can control their own data. These encryption and Edge solutions will be invi


bitcoin:
Security is one of the hottest topics in today’s ever-evolving digital world. A steady flow of debate continues to take place at tech forums worldwide on topics like encryption, passwords, two-factor authentication, hardware wallets and the like.
As cryptocurrencies and the tools being used to manage them take shape, questions loom about the most efficacious ways to protect both user assets and privacy. One individual who is at the epicenter of this active space is Paul Puey. He is co-founder and CEO of EdgeSecure, a blockchain-inspired, decentralized, open-source, zero-knowledge, global information security solution platform. Airbitz, his signature enterprise was birthed in 2013 as a bitcoin wallet provider and merchant directory. Today, he’s orchestrating a rebrand of this wallet, now called EdgeSecure.In an interview with Bitcoin Magazine, Puey talks about the tricky balance between new security and privacy measures being introduced and user experience. He also explores an emerging theme called “securing the edges” that forms the basis of his current workBM: What sort of problems are you attempting to solve these days? PP: The aspect of cryptocurrency we initially wanted to address revolved around how to effectively use secure keys. That was the impetus behind our decision to build a feature rich, functionally rich wallet at Airbitz over the years. We feel like this has really differentiated us in the whole area of key management. BM: How does your concept of EdgeSecure fit in here? PP: Our goal has been to broaden Airbitz by turning our key management standard into a platform for other apps. Even before we rebranded, we were already using the term Edge Security to examine how to come up with a solution that’s different from enterprise security. We view our approach as fundamentally different in the sense that we’re not trying to make a router or server more secure. Rather, our aim is to take data and secure it before it ever hits a device. In short, we are able to secure data before it goes out onto a network or server. People and their devices are what we are trying to secure. That’s where the term Edge comes from — before a user’s data ends up on their device, goes out to a network, goes onto a server — the encryption of that data happens first, as we say, “on the edges.” BM: But what about server networks? PP: We still believe that server security is important. But the visibility and encryption of that data all happens first before the data gets saved, broadcast and sent out on the network or gets onto a server. The concept of making data private and secure to the point where only the user can access it “on the edges” has never been an area of focus for cybersecurity companies. BM: So, in a nutshell, how does all of this actually work? PP: It works through a combination of technologies we’ve had for decades but have never been packaged the way we are seeking to. The technology that we’ve developed involves encrypting data on the client side. Most of the software out there doesn’t do this. Rattle off any app that you are running on your computer or your phone, and the data you generate and create is not encrypted, let alone automatically backed up. BM: Are there other security measures you’ll be employing? PP: We’ve also added two-factor authentication, although I fundamentally hate it from a user experience point of view. Two-factor is particularly problematic and a poor approach if the second factor for authorizing access is a phone number or email address. It’s better than nothing, but it’s not what one would consider to be “good two-factor.” BM: Is there a solution to this? PP: Yes, since 2015, we’ve been employing what we call “one touch, two-factor,” where we take two-factor and make it invisible by baking it in our Airbitz app. This eliminates the need for notification by SMS or email, or via an app like Authy or Google Authenticator. BM: Can you talk a bit about password recovery? This can be a big issue with

crypto users. PP: It is indeed. Think about this for a moment: If you lose your mobile ph


ion per year. In Europe, the market is 24 billion euros on an annual basis.“While comparisons between such estimates and ours are imprecise for a number of reasons (and the illegal activity captured by our estimates is broader than just illegal drugs), they do provide a sense that the scale of the illegal activity involving bitcoin is not only meaningful as a proportion of bitcoin activity, but also in absolute dollar terms,” the paper says.More Takeaways from the PaperWhile the amount of illegal activity taking place on the Bitcoin network appears to be relatively large, the paper indicates that the prevalence of this sort of activity has been declining since 2015 as more mainstream users have entered the market due to the interest in bitcoin as a store of value or speculative asset.The paper notes that the illegal activity involving bitcoin is inversely correlated to the number of searches for “bitcoin” on Google.“Furthermore, while the proportion of illegal bitcoin activity has declined, the absolute amount of such activity has continued to increase, indicating that the declining proportion is due to rapid growth in legal bitcoin use,” says the paper.The paper also indicates that privacy-focused altcoins, such as Monero and Zcash, may be cutting into bitcoin’s role as the currency of the online black market.The paper notes that it’s currently unclear if bitcoin is leading to an increase in black market activity or if this is simply offline activity moving onto the internet.“By providing an anonymous, digital method of payment, bitcoin did for darknet marketplaces what PayPal did for [eBay] — provide a reliable, scalable, and convenient payment mechanism,” the paper adds.According to the paper, this use case is the underlying value of the bitcoin asset.“Our paper contributes to understanding the intrinsic value of bitcoin, highlighting that a significant component of its value as a payment system derives from its use in facilitating illegal trade.”In addition to implications the online black market could have on the valuation of the bitcoin asset (a claim that is highly speculative as the bitcoin price has continued to see tremendous gains in the face of declining use for illicit payments), the paper adds that this realization also has ethical implications: those who choose to speculate on the bitcoin price may question whether they wish to provide liquidity for a payment system that enables illegal online transactions.This article originally appeared on Bitcoin Magazine (https://bitcoinmagazine.com/).


In a newly published paper (https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3102645) on the use of bitcoin for illegal activity, researchers from the University of Sydney, the University of Technology Sydney and the Stockholm School of Economics in Riga indicate that a quarter of all bitcoin users are associated with illegal activity.
The use of bitcoin for illicit purposes has long been the most controversial aspect of the cryptoasset, although it has taken a back seat to speculation around the bitcoin price over the past few years.In addition to estimating the scale of illegal activity involving bitcoin, the research paper also claims this sort of activity accounts for a significant portion of bitcoin’s intrinsic, underlying value.MethodologyIn the paper, which was co-authored by Sean Foley, Jonathon R. Karlsen and Tālis J. Putniņš, publicly available information is used as the basis to identify an initial sample of users involved in illegal activity on the Bitcoin blockchain. Seizures of bitcoin by law enforcement, hot wallets of darknet markets, and Bitcoin addresses on darknet forums are used here, in addition to the trade networks of users who were identified in this data set.Additionally, the researchers use a formula of their own creation to detect users likely to be involved in illegal activity by analyzing the entire public blockchain up until the end of April 2017. The formula for detecting criminals on the blockchain involves a wide variety of metrics such as transaction count, transaction size, frequency of transactions, number of counterparties, the number of darknet markets active at the time, the extent the user goes to conceal their activity and the degree of interest in bitcoin in terms of Google searches at the time.“Bitcoin users that are involved in illegal activity differ from other users in several characteristics,” the paper says. “Differences in transactional characteristics are generally consistent with the notion that while illegal users predominantly (or solely) use bitcoin as a payment system to facilitate trade in illegal goods/services, some legal users treat bitcoin as an investment or speculative asset. Specifically, illegal users tend to transact more, but in smaller transactions. They are also more likely to repeatedly transact with a given counterparty. Despite transacting more, illegal users tend to hold less bitcoin, consistent with them facing risks of having bitcoin holdings seized by authorities.”The paper also notes that bitcoin transactions between illegal users are three to four times denser, meaning those users are much more connected to each other through their transactions. This is consistent, the paper says, with illegal users taking advantage of bitcoin’s use as a medium of exchange, while legal users tend to view the cryptoasset as a store of value.The Scale of Illegal Activity on the Bitcoin NetworkAs with any research into the activities of criminals on the internet, it’s important to take the findings of this study with a grain of salt. Remember, this is a study on the activities of those who do not wish their activities to be discovered in the first place.For example, another study Bitcoin Magazine reported on last week indicated a much lower level of illegal activity — albeit limited to the concept of bitcoin laundering — on the Bitcoin network than what was found in the study being reported on today.Having said that, here are the levels of illegal activity on the Bitcoin network, according to the study:24 million illicit users, which is 25 percent of all users
36 million illicit transactions per year, which is 44 percent of all transactions
$72 billion worth of illicit transactions per year, which is 20 percent of the dollar-value of all transactions
$8 billion in illicit bitcoin holdings at the time of the study
51 percent of all bitcoin holdings throughout bitcoin’s history have been illegal in nature

The study compares Bitcoin’s black market to the markets for illegal drugs in the United States and Europe. In the United States, this market is worth $100 bill
