The Hill: Understanding what Facebook’s Libra is — and what it isn’t

The Hill: Understanding what Facebook’s Libra is — and what it isn’t. “When Facebook announced its own blockchain and cryptocurrency (both referred to as ‘Libra’), everyone from late-night comedy hosts to mainstream media outlets to regulators offered possible interpretations, implications, use cases and reasons for both encouragement and prohibition. In order to determine the usefulness (or lack thereof) of Libra, it is helpful to quickly demystify what these things are. After all, Facebook claims Libra ‘will enable a simple global currency and financial infrastructure that empowers billions of people.’ That is quite the goal.

Federal News Network: NARA considers blockchain to verify records amid rise in deepfake videos

Federal News Network: NARA considers blockchain to verify records amid rise in deepfake videos. “The National Archives and Records Administration is exploring whether blockchain technology can help records management officials keep track of their vast stores of information, following the successful rollout of the emerging technology elsewhere in government.”

Computer Weekly: Blockchain and deep neural networks show digital archive promise

Computer Weekly: Blockchain and deep neural networks show digital archive promise. “Researchers from the University of Surrey are set to present a paper in June at the Computer Vision and Pattern Recognition conference in Los Angeles, which describes a way to preserve the integrity of video, artificial intelligence (AI) models and digital archives.”

Caltech: Electron Tomography Database Changes the Game for Scientific Data Distribution

Caltech: Electron Tomography Database Changes the Game for Scientific Data Distribution. “Caltech researchers in collaboration with the start-up Alexandria have built the world’s first blockchain-powered platform for sharing scientific data. The Electron Tomography Database (ETDB), which is free and open to the public, uses blockchain to securely distribute and track ownership of data without relying on a central authority or moderation. The database is simultaneously a powerful new tool for basic research and proof of concept for a new model of scientific data sharing.”

Navigating Bitcoin, Ethereum, XRP: How Google Is Quietly Making Blockchains Searchable (Forbes Africa)

Forbes Africa: Navigating Bitcoin, Ethereum, XRP: How Google Is Quietly Making Blockchains Searchable. “It’s a balmy 80 degrees on a mid-December day in Singapore, and something is puzzling Allen Day, a 41-year-old data scientist. Using the tools he has developed at Google, he can see a mysterious concerted usage of artificial intelligence on the blockchain for Ethereum. Ether is the world’s third-largest cryptocurrency (after bitcoin and XRP), and it still sports a market cap of some $11 billion despite losing 83% of its value in 2018. Peering into its blockchain—the distributed database of transactions underpinning the cryptocurrency—Day detects a ‘whole bunch’ of ‘autonomous agents’ moving funds around ‘in an automated fashion.'”

Wired: A New Tool Protects Videos From Deepfakes and Tampering

Wired: A New Tool Protects Videos From Deepfakes and Tampering. “Video has become an increasingly crucial tool for law enforcement, whether it comes from security cameras, police-worn body cameras, a bystander’s smartphone, or another source. But a combination of ‘deepfake’ video manipulation technology and security issues that plague so many connected devices has made it difficult to confirm the integrity of that footage. A new project suggests the answer lies in cryptographic authentication.”
