“Blockchain: Hype or Hope” – Radia Perlman

January 15 @ 12:00 pm - 1:00 pm

Radia PerlmanAbstract

Is blockchain a game-changing technology that will revolutionize civilization as we know it? Or is most (if not all) of what we hear hype? This talk describes the design behind Bitcoin’s blockchain, the goals which led to that design, and the actual properties of that design (as opposed to the asserted properties of the design). Then we explore variants of blockchain. Then we discuss problems that people might think suited for blockchain, explore alternatives, and co


Radia Perlman’s work has had a profound impact on how computer networks work today. It enables huge networks, like the Internet, to be robust, scalable, and largely self-managing.

Her technology also transformed Ethernet from a technology that could support a few hundred nodes within a building, into a technology that could support networks of hundreds of thousands of nodes.

She has also made important contributions in network security, including robustness despite malicious trusted participants, assured delete, key management for data at rest encryption, and DDOS defense.

She is currently a Fellow at Dell EMC, and has taught as adjunct faculty at MIT, Harvard, and University of Washington.

She wrote the textbook “Interconnections”, and co-wrote the textbook “Network Security”. She holds over 100 issued patents.

She has received numerous awards including induction into the Inventor Hall of Fame, lifetime achievement awards from

ACM’s SIGCOMM and Usenix, election to National Academy of Engineering, induction into the Internet Hall of Fame, and an honorary doctorate from KTH.

She has a PhD in Computer Science from MIT.
