How Blockchains Could Make Governments More Efficient

For many, the idea of “government efficiency” is an oxymoron. There are multiple layers of bureaucracy and entire political movements that have emerged around this concept, to seemingly no avail.

But what if governments could be run more efficiently through open access to records and better delivery of services? That’s the hope that blockchain applications offer.

How Distributed Ledgers Can Illuminate the Metals Supply Chain

In the metals and mining industry, often you want to know where your product is coming from. End users want to know if the source material is “conflict free,” that is, it’s not coming from a war zone or being mined illegally.

And the immutability and decentralized nature of blockchains mean that they can be used as ledgers to track metals across the globe. For instance, the Ethereum-driven company ConsenSys is creating a blockchain consortium called Minerac to team with metal concentrates platform Open Mineral to make mineral trading and metals supply chains more efficient.

How Blockchains Can Make Vehicle Data Visible for All Owners

Driving is such an American ideal that few can imagine a world without wheels. But paying for insurance and tracking titles has often been complicated.

A nonprofit group based in Berkeley, California, is leading the charge to bring blockchains into the way we pay for transportation and simplify this aspect of our vehicle-driven lives. The Mobility Open Blockchain Initiative (Mobi) was launched in May “to explore blockchain for use in a new digital mobility ecosystem that could make transportation safer, more affordable, and more widely accessible.”

Mastercard Is Looking to Stem Theft Through Blockchain Technology

Thieves who “skim” credit card numbers are stealing some $2 billion globally every year. They simply pick up the magnetic images from these cards and they’re off to commit crimes with the stolen data.

Mastercard and other credit card companies are working on solutions that employ blockchains to end these information thefts. The credit card giant, which first began eyeing blockchain technology to thwart thefts in 2016, has applied for several patents for the nascent applications.

Leveraging Blockchains to Track the Marijuana Supply Chain

With some U.S. states and Canada now legalizing marijuana for recreational use, the need for a reliable way of monitoring the pot supply chain is greater than ever. Can blockchain technology do that effectively?

There’s some evidence that distributed databases may be able to track where marijuana is grown and how it gets to suppliers. There’s also optimism that it’s a solution that can eliminate black market distribution.
