“Maybe we don’t have to store everything ourselves.”
That’s Tadge Dryja, cryptocurrency research scientist at the MIT Digital Currency Initiative, explaining the concept behind his bitcoin scaling solution, “utreexo.”
Based on an idea that has been pursued by developers for many years, utreexo seeks to streamline an aspect of bitcoin’s code that leads to heavy storage requirements over time.

““I thought I would go to jail.”
That’s why Tadge Dryja, one of two principal researchers who would go on to envision lightning – what has become arguably the most important innovation in the quest to bring bitcoin to the masses – kept his passion for the technology to himself when he first heard about it in 2011.”

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.
Read MoreOne 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. In Bitcoin, this is stored as a collection of "Unspent transaction outputs", or "utxo"s, which are somewhat unintuitive, but provide privacy and efficiency benefits over the alternative "account" based model used in traditional finance.

Read MoreThe MIT Technology review interviews Robleh Ali, former manager of digital currency for the Bank of England, now research scientist at the MIT Digital Currency Initiative, on why initial coin offerings are dangerous and how to make them more useful. From the piece:
What do you think are the main misconceptions about ICOs?
The problem with ICOs is they want to ride two horses. The use of the word “coin” implies that the tokens being sold are money. The phrase “initial coin offering” is deliberately evocative of “initial public offering,” which is about a company selling shares to the public. They want to ride the Bitcoin horse by saying, “We’re not a security—it’s just money,” but they also want to ride the “You’re buying into a future enterprise that will be worth a lot of money” concept that’s inherent in the sale of shares. That’s one of the big tensions with ICOs, that lack of clarity, and that’s something that needs to be fixed.

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.
