A Decade of Digital Currency at MIT
A year ago I toured the gold vault beneath the New York Fed. You might recall it from the classic 1995 movie Die Hard with a Vengeance, but in case you aren’t familiar: It’s the world’s largest depository of monetary gold, storing over 6,000 tons 80 feet below Manhattan and protected by airtight vaults and its own police force.
The first thing I thought when I was down there was wow, gold is very shiny. The second was wow, gold bars are surprisingly heavy, in part because of its density (bars are 28 pounds). They make you wear metal shoe covers to hold one in case you drop it on your foot. But the third thing I thought is “THIS is what the global monetary system rests on? This is just so antiquated.”

Nicolas Xuan-Yi Zhang, "A Multi-Currency Exchange and Contracting Platform"
The DCI’s Nicolas Xuan-Yi Zhang coauthored a paper at IMF on multi-currency exchange.
Cross-border payments can be slow, expensive, and risky. They are intermediated by counterparties in different jurisdictions which rely on costly trusted relationships to offset the lack of a common settlement asset as well as common rules and governance. In this paper, we present a vision for a multilateral platform that could improve cross-border payments, as well as related foreign exchange transactions, risk sharing, and more generally, financial contracting. The approach is to leverage technological innovations for public policy objectives. A common ledger, smart contracts, and encryption offer significant gains to market efficiency, completeness, and access, as well as to transparency, transaction and compliance costs, and safety. This paper is a first step aiming to stimulate further work in this space.

The MIT Digital Currency Initiative bids farewell to Tadge Dryja
Five years ago, I was in the Boston area for a week and I hung out at the DCI.
It wasn't much of a space back then—really more like a closet. But there were ethernet ports in the walls, assorted cables, and computer accessories, and a couch with occasional undergrads hanging out, coding, or discussing the finer points of cryptocurrencies. It was welcoming, and a lot of fun. I brought a computer and started working, and talking to people about Bitcoin, and helping some students with their projects…
