Today, MIT Technology Review announced the third annual Business of Blockchain event, which will take place on May 2, 2019 at the MIT Media Lab. The event is held in collaboration with the Digital Currency Initiative, an MIT Media Lab research group focusing on cryptocurrencies and their underlying technology, and brings together industry leaders and pioneers in this emerging field to examine the technology, ethics, and impact of blockchains.
Knowledge @ Wharton's 'How a New Technology Can Disrupt the Global Supply Chain'
An interdisciplinary team from MIT, Wharton and Boston College has created a new blockchain-based system that has the potential to disrupt the global supply chain. Called ‘b_verify,’ the system is designed to help small and medium-size enterprises — especially those in developing nations — get financing from lenders at potentially better terms while mitigating warehouse deposit fraud. The system brings greater transparency to a key part of the supply chain, which can have a big impact on global trade financing. Bverify introduces a series of blockchain technology innovations tailored to facilitate supply chain finance and operations management.
Blockchain and the Value of Operational Transparency for Supply Chain Finance
by Jiri Chod (BU), Nikolaos Trikakis (MIT), Gerry Tsoukalas (Upenn Wharton), Henry Aspegren (MIT), and Mark Weber (MIT). Nominated for an award in the Journal of Management Science. Sept 15th, 2018
In this paper, we develop a new theory that shows signaling a firm's fundamental quality (e.g., its operational capabilities) to lenders through inventory transactions to be more efficient --- it leads to less costly operational distortions --- than signaling through loan requests, and we characterize how the efficiency gains depend on firm operational characteristics such as operating costs, market size, inventory salvage value and failure probability.

"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.
