VI3NNA Congress 2026 is an invite-only gathering bringing together leaders from Web3, AI, finance, and regulation to help shape Europe’s digital economy. Held on May 19–20 at MQ Libelle in the MuseumsQuartier, the congress connects policy, innovation, and capital across adoption, regulation, infrastructure, transparency, and growth. The program is structured around five focused workstreams covering topics such as MiCA, the AI Act, eIDAS 2.0, and TradFi–DeFi convergence, culminating in the Vienna Declaration whitepaper.
