"DCI Working Groups: the blockchain sandbox at MIT" On Medium by DCI's Alin Dragos
Our MIT motto, mens et manus, is a call-to-action to be more than mere technologists and to learn (by doing!) how to be thoughtful makers of a better world. The Digital Currency Initiative (DCI) Working Group Program creates a sandbox for interdisciplinary teams of students to hack on pressing topics in cryptocurrency and blockchain technology. Students from the Blockchain Lab will collaborate with instructors, companies and DCI to investigate uses of blockchain technology and how to integrate it into viable business models.

Utreexo: A dynamic accumulator for Bitcoin state - A description of research by Thaddeus Dryja
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.

Cellular structure for a digital fiat currency
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.
Does Your Supply Chain Need a Blockchain?
Many new digital technologies at various stages of development hold promise for manufacturers and the supply chain. The challenge for management teams is knowing which technologies to invest in—and when. Case in point: blockchain technology. Once seemingly at the far end of the time horizon, blockchains are suddenly poised for rapid growth. Why? Because they offer a solution to the growing problem of how to manage increasingly complicated networks of manufacturers and suppliers at a time when transparency, speed, and agility are critical.
