The 13th BIU Winter School on cryptography

Blockchain Technologies

February 20-23, 2023

School Overview

Blockchain technology and cryptocurrencies have introduced new application scenarios for cryptography, and driven novel cryptographic constructions. The 13th BIU Winter School on Cryptography will focus on recent advances in blockchain technology. The program will cover the following topics: introduction to blockchains, consensus protocols, smart contracts, crypto-wallets, bridges, and DeFi. 

The program aims to give a taste of key topics in the area, focusing on recent developments in the field. The target audience for the school is graduate students and postdocs, as well as people from the blockchain community (we will assume that participants have taken at least one university-level course in cryptography). However, all faculty, undergrads, and people in relevant industries with the necessary background are welcome. The winter school is open to participants from all over the world; all talks will be in English.
