Blockchain, a nascent technology that offers highly secure digital data tracking, has caught the interest of AV companies and automakers, who are exploring how it can be used to track components in supply chains and protect valuable data.

Why it matters: More complex cars will generate more data and as blockchain technology develops, it could offer a secure way to manage that data while providing additional benefits to passengers.

Background: Eventually numerous autonomous modes of transportation could become available, including vehicles used for ride-hailing, car sharing, and even public transportation like circulators.

  • These AVs will process massive amounts of data including from their sensors, on road conditions, from other connected devices, and on how vehicle parts are operating. Blockchain could ensure the authenticity of that data.
  • Blockchain could also enable customers to use multiple transportation systems with a single digital ID, paying for transit tickets, insurance if needed, and streaming services. They could potentially have secure, transparent access to their data, agnostic of any brand of transportation used.

What's happening: In 2018 BMW, GM, Ford and Renault started a joint blockchain initiative. Other automakers are forging individual partnerships with tech companies.

  • Porsche and Berlin-based startup XAIN tested how blockchain could be used to lock and unlock cars, grant temporary access to parking attendants, and securely log car data to make cars and their data more difficult to steal.
  • Volkswagen has partnered with blockchain platform IOTA to track data for evaluating vehicle performance and to track over-the-air software updates in order to protect against cybersecurity threats.
  • Daimler AG is pursuing a blockchain-focused partnership with Germany's Landesbank Baden-Württemberg (LBBW), and has also joined Hyperledger, a collaborative, cross-industry blockchain project focused on supply chain tracking and transparency around payments.

Yes, but: A lack of standards across these projects could, counterintuitively, impede data transparency and restrict customer choice if automakers and service providers attempt to tie customers to just one service or another with a proprietary blockchain system.

What we're watching: Advanced vehicle technology is just starting to experiment with blockchain, a technology that is very much in development. If blockchain is used widely as vehicles grow more sophisticated, it could be a way to ensure data transparency and security across the industry.

Rep. Dan Crenshaw says he'll be blind for a month after eye surgery

Rep. Dan Crenshaw (R-Texas) said in a statement Saturday he will be blind for roughly a month after getting surgery to reattach the retina in left eye.

Why it matters: Crenshaw, who lost his right eye and sustained severe damage to his left eye during his third deployment to Afghanistan in 2012, said he will be "pretty much off the grid for the next few weeks."

NASA's Mars helicopter is a test for the future of space exploration

NASA is set to fly the first test flight of its tiny Ingenuity helicopter on Mars Sunday, marking the advent of drones for space exploration.

Why it matters: If successful, this flight will be the first time a human-built aircraft has flown on a world other than Earth, opening the door to new means of exploring planets far from our own.

The global future is looking dark and stormy

A new 20-year-forecast for the world: increasingly fragmented and turbulent.

The big picture: A major report put out this week by the National Intelligence Council reflects a present rocked by the COVID-19 pandemic. How the next two decades will unfold depends largely on whether new technologies will ultimately unite us — or continue to divide us.
