Know your crypto customer? The industry is facing down the Travel Rule.

The crypto Travel Rule group, which includes Coinbase, Anchorage Digital and Robinhood, offers a way for companies to comply with a key FinCEN rule.

Sending huge amounts of money by wire anonymously violates a government rule that says information about who is sending how much to whom must “travel” with that transaction.

But the Travel Rule, as it is called, has been a headache in crypto, where pseudonyms reign (who’s Satoshi Nakamoto again?). Largely by design and to the chagrin of law enforcement, keeping track of personal information isn’t the norm in decentralized, blockchain-based transactions.

That could change with a new crypto organization that’s building a system that would enable its members to comply with Travel Rule requirements, while maintaining a degree of privacy and anonymity valued in crypto.

The Travel Rule Universal Solution Technology, or TRUST, is introducing itself Wednesday with 18 initial members, including major companies like Coinbase, Circle, Anchorage Digital, Gemini and Robinhood.

The Travel Rule requirement is challenging for crypto, since “unlike traditional financial institutions,” crypto companies use “a very decentralized infrastructure that we rely upon in order to track these different transactions,” Coinbase Chief Legal Officer Paul Grewal said. “With permissionless blockchains, there's no way to understand whether a wallet address on the other side of a transaction belongs to a financial institution or to an individual or anybody else.”

TRUST hopes to fix that with a network in which exchanges will be able to verify each other’s addresses before facilitating transactions, Grewal said. (In the United States, transactions of $3,000 or more must comply with the Travel Rule.)

The network also includes two important design features: It will not store “sensitive kinds of customer information, either on the TRUST platform itself or with any kind of third party,” Grewal said. Any information shared on the network will be encrypted, and addresses will be hashed before they are shared, he said.

“We encrypt that transmission, so that only the sender and the recipient have access to it, and then that way, we make sure that no one is interfering with that or gaining unauthorized access in some untoward way,” he said.

The network will make it possible “to first confirm the identity of that wallet address before any information is sent, and then to have the information transmitted peer-to-peer directly from one exchange to the other so that we're not pooling information in any central place that could obviously become a honeypot for nefarious actors,” Grewal said.

Michael Fasanello, director of Training and Regulatory Affairs at the Blockchain Intelligence Group, said that was a real risk.

“That kind of curated personal information is, quite literally, digital gold,” he said, which is why encrypted and decentralized data would be “a critical part of any Travel Rule implementation in digital assets.”

Grewal said the initiative has received “an extraordinarily positive reaction” from FinCEN, the Treasury Department’s financial crimes enforcement body. FinCEN could not be reached for comment ahead of the group’s announcement.

Jonah Crane, a partner at the Klaros Group, said the new organization “should provide a path to compliance for participating firms.” Christine Brown, Robinhood’s COO for crypto, said the new organization shows that “it takes a community of crypto businesses and platforms to work together to find a solution to preserve customer privacy while meeting the legal requirements of the Travel Rule.”

It's OK to cry at work

Our comfort with crying at work has changed drastically over the past couple years. But experts said the hard part is helping workers get through the underlying mental health challenges.

Tech workers and workplace mental health experts said discussing emotions at work has become less taboo over the past couple years, but we’re still a ways away from completely normalizing the conversation — and adjusting policies accordingly.

Everyone seems to be ugly crying on the internet these days. A new Snapchat filter makes people look like they’re breaking down on television, crying at celebratory occasions or crying when it sounds like they’re laughing. But one of the ways it's been used is weirdly cathartic: the workplace.

In one video, a creator posted a video of their co-worker merely sitting at a desk, presumably giggling or smiling, but the Snapchat tool gave them a pained look on their face. The video was captioned: “When you still have two hours left of your working day.” Another video showed someone asking their co-workers if they enjoy their job. Everyone said yes, but the filter indicated otherwise.

Arm’s new CEO is planning the IPO it sought to avoid last year

Arm CEO Rene Haas told Protocol that Arm will be fine as a standalone company, as it focuses on efficient computing and giving customers a more finished product than a basic chip core design.

Rene Haas is taking Arm on a fresh trajectory.

The new path for Arm is beginning to come into focus.

Weeks after Nvidia’s $40 bid to acquire Arm from SoftBank collapsed, the appointment of Rene Haas to replace longtime chief executive Simon Segars has set the business on a fresh trajectory. Haas appears determined to shake up the company, with plans to lay off as much as 15% of the staff ahead of plans to take the company public once again by the end of March next year.

The great onshoring: Inside the transcontinental chip race

The second annual Trade and Technology Council emphasized the centrality of semiconductor onshoring to U.S.-EU military objectives.

For chip manufacturers, free-flowing subsidies for now might come at the cost of a potential overcapacity problem in the longer term.

The prospect of global conflict permeated the room at this year’s Trade and Technology Council, which concluded in France earlier this week. The second annual gathering of U.S. and EU officials yielded a joint statement that mentioned some form of “Russia” or “Ukraine” more frequently than “technology,” “regulation,” “investment,” “security” or “competition.”

The conflict in Ukraine, having already escalated into a U.S. proxy war, seemingly convinced the EU to fall in line with the American tech policy agenda.

2- and 3-wheelers dominate oil displacement by EVs

Increasingly widespread EV adoption is starting to displace the use of oil, but there's still a lot of work to do.

Electric vehicles are starting to make a serious dent in oil use.

Last year, EVs displaced roughly 1.5 million barrels per day, according to a new analysis from BloombergNEF. That is more than double the share EVs displaced in 2015. The majority of the displacement is coming from an unlikely source.
