Blockchain and Decentralized Applications

Event Report

Arjun, an accomplished individual with a background in product development, protocol design, and combating misinformation, led a series of interactive workshops from March 4-7, 2024. The workshops focused on crucial aspects of Web 3 technology, including decentralized end-to-end encryption and the design of decentralized applications.

With Arjun’s expertise in infrastructure development and his role at Threshold/NuCypher, a prominent decentralized network, the workshops provided valuable insights into building censorship-resistant and privacy-focused applications. Arjun’s contributions to the development of TACo, an encrypted access control plugin, and the Stable Yield mechanism for small staker welfare showcased his innovative approach to addressing critical issues within the Web 3 ecosystem.

The workshops attracted significant interest, with 50 students attending in person and an additional 300 participating online. This diverse audience reflects the growing enthusiasm and demand for knowledge in emerging technologies like Web 3. Arjun’s multifaceted background, including experience in NLP product development and policy research, undoubtedly enriched the workshop discussions and provided attendees with valuable perspectives on the intersection of technology, privacy, and societal impact.


The Center for Cyber Security Systems and Networks is pleased to present a three-day workshop on “Blockchain and Decentralized Applications” featuring Arjun Hassard as the distinguished speaker. This workshop will delve into the core value propositions and building blocks of blockchain technology, with a special focus on decentralized applications (dApps), Web3 infrastructure, and trust-minimized end-to-end encryption.
