“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.

WGBH News: More local ATMs Will Soon Dispense 'Cryptocurrencies' - Arun Rath Interviews DCI's Director Neha Narula and Others
A celebration of 10 years of Bitcoin features DCI's Tadge Dryja story:
““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.”

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.
Static-Memory-Hard Functions, and Modeling the Cost of Space vs. Time
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. 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.
Responsible disclosure in the era of cryptocurrencies
By Thaddeus Dryja, Quanquan C. Liu and Sunoo Park
Static-Memory-Hard Functions, and Modeling the Cost of Space vs. Time was presented at the Cryptography Conference 2019, which is organized by the International Association for Cryptologic Research (IACR).
Cellular structure for a digital fiat currency
DCI Bitcoin Core developer Cory Fields shares his experience disclosing a critical Bitcoin Cash vulnerability.
Another perspective on cryptocurrency regulation
This paper by DCI Reserach Scientist Robleh Ali sets out a structure for a digital fiat currency system. The primary benefit of the cellular structure is that it lowers barriers to entry for payments by using trustless intermediation between cells in the system. The larger purpose of this structure is to create an open foundation for a decentralized financial system in which competition can thrive but which cannot be captured by private interests.
A Former Top Wall Street Regulator Turns to the Blockchain
This week our colleague Gary Gensler was profiled in The New York Times talking about how Ethereum and Ripple should be classified as securities. DCI director Neha Narula continues the conversation about how cryptocurrencies and tokens should be regulated.
The problem with ICOs is that they’re called ICOs
From the New York Times, Nathaniel Popper profiles DCI Senior Advisor Gary Gensler, former chairman of the Commodities Futures Trading Commission ahead of his statements on the regulation of cryptocurrencies to be made at the Business of Blockchain Conference.
This is how Bitcoin works
The 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:

Initial Coin Offerings and the Value of Crypto Tokens
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.
zkLedger: Privacy-Preserving Auditing on Distributed Ledgers
This paper by Christian Catalini and Joshua Gans explores how entrepreneurs can use initial coin offerings — whereby they issue crypto tokens and commit to accept only those tokens as payment for future use of a digital platform — to fund venture start-up costs.
Auditing and financial oversight are critical to proving institutions are complying with regulation. This paper presents zkLedger, the first system to protect ledger participants’ privacy and provide fast, provably correct auditing.
