Libra hasn’t even rolled out yet, but it’s already prompted several countries, including China, to accelerate the development of their own national digital currencies. “We’re trying to change the system, and there are a lot of people who are incentivized for the global financial system not to change,” she says. Today she serves as head of strategy for the latter, where she works with a team of digital currency developers.įacebook and its founder, Mark Zuckerberg, endured sharp criticism after announcing the plans for Libra. When she realized that no one at Facebook was working on blockchain, she volunteered and quickly became the company’s digital currency evangelist, shepherding the development of both its open-source blockchain infrastructure, Libra, and its currency application and digital wallet, Novi. She could see that a seismic shift in the global financial community was coming. In the summer of 2017, Morgan Beller approached her supervisor on Facebook’s corporate development team with a proposal: what if she began spending the bulk of her job researching how the social-media giant could enter the digital currency market?īeller was so new at Facebook that she was still completing her orientation, but she’d cut her teeth at a venture capital firm, where she’d worked on early cryptocurrency investments. Perhaps this will allow scientists to spot data quirks that would otherwise go unnoticed. She hopes to make exploration tools more interactive and visual so they’ll be less daunting.

This system allowed them, they said, to predict which tiles users wanted about 25% better than existing prefetching systems they benchmarked against, almost halving the latency.īattle has devoted her career to designing systems and interfaces that help researchers sifting through data do their work better and faster. “Sensemaking” is a closer examination meant to test those ideas, and “navigation” is a transition between the two. They dubbed the three phrases “foraging,” “sensemaking,” and “navigation.” They suppose that users in the “foraging” phase are browsing at a coarse level, in order to come up with new ideas. It attempts to discern first which “analysis phase” a user is in, and then what tiles of data might be wanted next.

But how to predict what to prefetch? That depends on understanding the user’s behavior.īattle and her colleagues developed a more efficient prediction system. A common way to do this is to predict which parts of the data a user is likely to need and then “prefetch” them.

The goal is to reduce latency, so that a user can pan and zoom across the data set without perceptible delay.
