The Newest Haven for Cryptocurrency Companies? Wyoming

godspeed, my friend), there are a few telltale signs. First, look for the live bulls and the yellow Lambos. But if they’ve fallen victim to cost-cutting or newfound modesty, then look for a procession of cream-colored cowboy hats. They belong to a retinue of lobbyists and legislators from Wyoming, preaching the virtues of their state as a mecca for blockchain.

Wyoming’s transformation into a blockchain booster is somewhat legendary in cryptocurrency circles. Until recently, strict money-transmitter laws meant residents there couldn’t even use a Coinbase account. But over the past two years, Wyoming has enacted 13 blockchain laws, with a raft of other proposals on the way. The question is, what does the country’s least-populous state, far from tech hubs and long associated with an unhealthy dependency on resource extraction, want with blockchain?

“The ethos of blockchain and the ethos of Wyoming are very similar,” says Caitlin Long, cofounder of the Wyoming Blockchain Coalition, a lobbying group responsible for pushing for the crypto-friendly bills, many with a libertarian bent.

Wyoming’s push is a reflection of the nation’s patchwork of state laws, created in the absence of clear federal rules. Some, like New York, favor rigorous regulation. The state’s Bitlicense regime, which began in 2015, involves a strict vetting process for companies that want to deal with New York residents, prompting complaints that it deters innovation. Legislators in Wyoming, as well as neighboring Colorado and Montana, see that as an opening.

“It’s been good for Wyoming that the federal government has been proving its stripes of incompetency,” says Tyler Lindholm, a state representative who, at 6’7″, does much to increase the visibility of the cowboy hats.

Lindholm and Long first partnered on blockchain legislation two years ago. Long, a former executive at Morgan Stanley, became interested when she discovered that state regulations prevented her from donating bitcoin to her alma mater, the University of Wyoming. Lindholm, a longtime cryptocurrency enthusiast, had previously tried to tackle that issue. But his fellow legislators mostly associated cryptocurrency with drug sales and scams. “This was their first blush with crypto—even hearing about it,” Lindholm says. “I got my ass whipped pretty bad.”

Their fortunes improved by casting cryptocurrency as a way to replace flagging state revenue from the coal industry, Long says. Working with lawyers from Consensys, a company that builds and promotes Ethereum applications,

The Bottom Line

The Ledger Nano X is a great cryptocurrency hardware wallet. It fixes all the issues that its predecessor had, but does so at twice the price — which is still alright if you’re serious about crypto.

If you’re serious about cryptocurrency, one gadget that you simply must have is a hardware cryptocurrency wallet. One of the most popular such wallets is Ledger’s Nano S — a USB flash drive-sized, practical device that supports nearly every cryptocurrency you can think of. 

But the Nano S has been around for a couple of years, and its age is showing — it’s fairly slow and its memory is limited, meaning it only works with a couple (typically 3) of different cryptocurrencies at the same time. 

In January, Ledger announced a new hardware wallet, the Ledger Nano X. It’s a significant improvement over the Nano S in several key areas: It’s faster, has a bigger screen, it’s wireless, and it can support many more coins (up to 100) at the same time. 

At $119, the Nano X also significantly pricier than the $59 Nano S, and now I’ve had the chance to test a review unit out and see whether the price premium is worth it.

First, a short introduction to hardware cryptocurrency wallets. They are hardware devices which keep your crypto private keys and let you securely access your cryptocoins with a PIN. By requiring actual interaction with the hardware at certain points, such as pressing a key or confirming that a cryptocurrency address is accurate on the screen, they add a much-needed layer of security over software wallets. 

Ledger's Ledger Live software works well both on the PC and the iPhone. It's available for all major platforms, including Android. macOS and Windows.

On the Ledger Nano X, your cryptocurrency private keys (which are long strings of symbols that let you spend your cryptocoins) are kept “isolated” in a “secure element” chip and none of the applications interacting with the Nano X never get to see them. Even if you plug the Nano X into a compromised PC, your private key should remain safe. 

Setting up

As is the case with most hardware wallets, setting up the Nano X for the first time takes a while, but the process is largely painless. The device is, again, USB thumb-like in size, though it is a little bigger than the Nano S. It comes with a very short set of instructions, three seed phrase cards, and a USB-C to USB-A c

Not so fast, said county officials. They pointed to a different culprit: a giant coal plant halfway across the state. If energy from the dam went to bitcoin mining, they said, the county as a whole would wind up using more coal. In April, officials required all future mines to build their own renewable power.

Missoula County was on the right track, says Christian Stoll, an energy researcher at the Technical University of Munich. In a paper published Wednesday in the journalJoule,his team takes a closer look at the energy consumption of bitcoin mining, based on where miners are located and the types of machines they are using. “Coal is fueling Bitcoin,” he says. “The question is how to prevent it, and that’s up to local regulators.”

Bitcoin mining, a process called “proof-of-work,” involves a global network of machines racing to solve complex math. In return for helping to keep the network secure, the solver receives bitcoin. When it comes to measuring energy use, the global nature of that activity makes it difficult to study; it’s hard to know what kinds of machines are running, where they’re located, and the fuel used to supply the electricity.

Those unknowns have led to wildly varying estimates. One study said that growth in bitcoin mining alone could result in a 2 degree Celsius increase in global temperatures. But others say such estimates are inflated as miners increasingly flock to sources of cheap renewable energy, like hydropower.

Stoll’s team was able to take a more granular look thanks to a stroke of good timing. Last year, three Chinese makers of mining hardware, responsible for producing nearly all of t

Jigsaw Bought a Russian Twitter Troll Campaign as an Experiment

Internet Research Agency, an entire company housed on multiple floors of a corporate building in St. Petersburg, concocting propaganda at the Kremlin’s bidding. But a targeted troll campaign today can come much cheaper—as little as $250, says Andrew Gully, a research manager at Alphabet subsidiary Jigsaw. He knows because that’s the price Jigsaw paid for one last year.

As part of research into state-sponsored disinformation that it undertook in the spring of 2018, Jigsaw set out to test just how easily and cheaply social media disinformation campaigns, or “influence operations,” could be bought in the shadier corners of the Russian-speaking web. In March 2018, after negotiating with several underground disinformation vendors, Jigsaw analysts went so far as to hire one to carry out an actual disinformation operation, assigning the paid troll service to attack a political activism website Jigsaw had itself created as a target.

In doing so, Jigsaw demonstrated just how low the barrier to entry for organized, online disinformation has become. It’s easily within the reach of not just governments but private individuals. Critics, though, say that the company took its trolling research a step too far, and further polluted social media’s political discourse in the process.

“Let’s say I want to wage a disinformation campaign to attack a political opponent or a company, but I don’t have the infrastructure to create my own Internet Research Agency,” Gully told WIRED in an interview, speaking publicly about Jigsaw’s year-old disinformation experiment for the first time. “We wanted to see if we could engage with someone who was willing to provide this kind of assistance to a political actor … to buy services that directly discredit their political opponent for very low cost and with no tooling or resources required. For us, it’s a pretty clear demonstration these capabilities exist, and there are actors comfortable doing this on the internet.”

Trolls Behind the Counter

In early 2018, Jigsaw hired a security firm to sniff around Russian-language black-market and gray-market web forums for disinformation-for-hire services. (That company asked WIRED not to name it, to preserve its ability to work on underground forums.) Browsing sites like Exploit, Club2Crd, WWH, and Zloy, the security firm’s researchers say they didn’t find explicit offers of trolling or disinformation campaigns for sale, but plenty of related schemes like fake followers, paid retweets, and black hat search engine optimization. The team guessed, though, that more awaited beneath the surface.

“If we look at this as window shopping, we hypothesized that if someone was selling fake likes in the window, there’s probably something else behind the counter they might be willing to do,” says Gully. When researchers for the security firm Jigsaw had hired started chatting discreetly with those vendors, they found that a few did in fact offer mass-scale social media posting on political subjects as an unlisted service.

“That … is an extremely controversial and risky thing to do.”

Thomas Rid, Johns Hopkins University

Before it bought one of those paid trolling campaigns, Jigsaw realized that it first needed a target. So together with its hired security firm, Jigsaw created a website—seeded with blog posts and comments they’d written to make it appear mor
