And the immutability and decentralized nature of blockchains
mean that they can be used as ledgers to track metals across the globe. For

and metals supply chains more efficient.
Driving is such an American ideal that few can imagine a world without

A nonprofit group based in Berkeley, California, is leading the charge
to bring blockchains into the way we pay for transportation and simplify this

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

technology to thwart thefts in 2016, has
applied for several
patents for the nascent applications.

optimism that it’s a solution that can eliminate black market distribution.
