Bridging the Decentralized Gap: Shared Hacker Values, Cypherpunk Roots, and the Future of Blockchains
AlexanderUrbelis, Phil Daian, Harry Halpin

This panel will delve into the deep-rooted connections between hacker and cypherpunk culture and the evolution of Ethereum and blockchain technology, tracing their shared emphasis on decentralization, privacy, and open-source principles. By revisiting the historical context of the 1990s Crypto Wars and projects like PGP and Tor, the discussion will highlight how these early movements laid the groundwork for the vision of a trustless, user-sovereign Internet. The panel also will aim to debunk common misconceptions that associate blockchains solely with scams or speculation, showcasing real-world applications such as the Ethereum Name Service and privacy-preserving technologies, while emphasizing the ecosystem’s pivot towards public goods and accessibility. Ultimately, the conversation will underscore the enduring, collaborative vision of both hacker and blockchain communities - advancing censorship resistance, user empowerment, financial privacy, and a decentralized digital future.

NymVPN: The First Real-World Decentralized Noise-Generating Mixnet for Anonymity
Harry Halpin

Nym is the first decentralized noise-generating mixnet to provision real-world network anonymity to Internet users even against nation-state adversaries. The aim here is to supersede existing VPNs in order to fight increasingly more powerful authoritarianism and surveillance. Unlike traditional centralized VPNs that can be de-anonymized by a global passive adversary - like the NSA - based on their traffic patterns, Nym adds noise (“cover traffic”) to existing Internet communications. Similar to Tor, Nym routes each packet separately over a decentralized network of servers, but unlike Tor, mixes traffic and adds noise at each hop. After being introduced at HOPE five years ago, NymVPN has now shipped. NymVPN is an easy to use app for all major operating systems that makes using the Nym network as easy as using a traditional VPN for ordinary people, with both a “fast” and “anonymous” mode. The “fast” mode features speeds comparable to centralized VPNs using the same decentralized network as the mixnet, but without mixing. Via the SDK, the Nym mixnet remains free to use by hackers to build the next generation of privacy infrastructure.
