You may not have heard of Vertcoin, a crypto project designed to curtail concentration in mining power in the interests of broad-based participation. But if you care about security, decentralization and open access for cryptocurrencies, then the questions raised by a recent breach of its blockchain will matter to you.
Today at the WIRED25 Summit, Neha Narula and Alexis Ohanian talked about some of the ways blockchain, the decentralized ledger technology at the heart of bitcoin and other "cryptocurrencies," could press forward through the current slump and actually become useful.
One of the earliest-seen and most persistent problems with Bitcoin has been scalability. Bitcoin takes the idea of "be your own bank" quite literally, with every computer on the bitcoin network storing every account of every user who owns money in the system.

The dot-com bubble of the 1990s is popularly viewed as a period of crazy excess that ended with hundreds of billions of dollars of wealth being destroyed. What’s less often discussed is how all the cheap capital of the boom years helped fund the infrastructure upon which the most important internet innovations would be built after the bubble burst.
Tadge Dryja, research scientist at the MIT Digital Currency Initiative, is featured in this recent WIRED article by Sandra Upson, "The Lightning Network Could Make Bitcoin Faster—and Cheaper." Tadge continues to lead the development of Lightning, now with us at the MIT Media Lab.
On Friday, MIT Technology Review published an article on the cryptocurrency IOTA. The headline stated that the currency “could outperform Bitcoin.” However, we here at the MIT Media Lab have issues with the story.
Imagine that every EHR sent updates about medications, problems, and allergy lists to an open-source, community-wide trusted ledger, so additions and subtractions to the medical record were well understood and auditable across organizations.
