Sub0 2025 is the flagship Polkadot conference — a three-day immersive Web3 festival taking place November 14–16 at Bubble Studios in Buenos Aires.
Gathering over 3,000 builders, creators, and innovators, it explores the future of a decentralized, censorship-resistant internet.
The program features 60 curated speakers across two stages, covering resilient infrastructure, privacy, governance, on-chain culture, and real-world blockchain impact. Attendees can also enjoy rooftop sessions, over 25 side events, and 13 live experiences that blend technology, art, and community.
With round-the-clock access, curated experiences, and private-chef catering, Sub0 combines brutalist aesthetics with a hands-on approach to innovation. Admission is free, including all-day beverages and meals – making it one of the most open and collaborative gatherings in the Web3 ecosystem.
