  • The godfather of the cryptocurrency movement is back with a plan to address bitcoin’s biggest shortcoming: speed.

    David Chaum, who built his own digital currency more than a decade before bitcoin was introduced, is unveiling a new platform that he claims would allow digital cash to be traded almost as quickly as physical cash.

    Mr. Chaum is introducing the platform, called Elixxir, at the Consensus conference in Singapore on Thursday. He says that Elixxir can process thousands of transactions a second—a dramatic increase over bitcoin’s current capability—and cuts down on the energy required to maintain the network…

    And his goals are bold.

  • There’s growing awareness that slick online services are far from free—and that we may be paying too high a price for some of them. Hyper-specific targeted advertisements are creepy, while using our data to tamper with elections raises surveillance risks to a new level. As more payments take place online via apps, a growing trove of personal data is ripe for exploitation.

    That’s where David Chaum comes in. His pioneering work in cryptography and digital payments predates bitcoin, and laid important work for its invention. Likewise, he made prescient warnings about online privacy long before data-sharing scandals at major tech companies like Facebook. “Everything you do could be known to anyone else, could be recorded forever,” Chaum told Wired magazine in 1994. “It’s antithetical to the basic principle underlying the mechanisms of democracy.”

    His latest venture is called Elixxir, a blockchain designed for fast, secure, and confidential messaging and payments at minimal expense. The design acknowledges that text messagesand payments—from WeChat to WhatsApp Pay—are increasingly intertwined, by popular demand.
