Blockchain Research Day  IDC | June 2021

Organizers

Eli Ben-Sasson (StarkWare), Ittay Eyal (Technion), Tal Moran (IDC)

Blockchain research touches on several different areas of computer science, inluding: distributed computation, algorithmic game theory, cryptography and network theory. 

The Israel Blockchain Research day is meant to be a periodic meeting place for students and researchers interested in blockchain research within computer science.

The 9th BIU Winter School on Cryptography: Zero Knowledge | February 18-21, 2019

School overview:

Zero knowledge is a fundamental tool of cryptography, in both theory and practice. It enables a party to prove an assertion without revealing anything but the fact that it is indeed true. The theory of zero-knowledge proofs has beautiful connections to complexity and is used to prove many basic theoretical results of cryptography. In addition, efficient zero-knowledge proofs have many applications, including efficient secure computation, advanced authentication schemes like anonymous credentials, transaction validation, and more.

In the 9th BIU Winter School on Cryptography, we will study the theory and practice of zero-knowledge proofs. The program will cover definitional issues and constructions.
