Ready to shape the decentralized future? Here’s what to expect at Web3 Summit 2025.
What Is the Web3 Summit?
The Web3 Summit, organized by the Web3 Foundation, is a community-driven event held at Funkhaus Berlin, a historic venue blending industrial charm with creative energy. Running from July 16-18, 2025, it’s designed for developers, researchers, and Web3 enthusiasts to collaborate on building a decentralized web. Unlike traditional conferences, the summit prioritizes open participation: attendees can propose talks, lead workshops, or host discussions in the Nodespace, an unconference-style area. A 72-hour hackathon, the Blockspace Symmetry Hackathon, offers developers a chance to compete for grants and build innovative solutions, as seen in 2024’s event with over 40 talks and 60+ speakers.
The Web3 Foundation, founded by Ethereum co-founder Dr. Gavin Wood, supports projects like Polkadot and Kusama, emphasizing resilient, decentralized systems. With a strict no-sponsorship policy, the summit ensures a focus on ideas over commercial interests, fostering authentic collaboration. Posts on X highlight its appeal, with
@Polkadot calling it a space where “researchers, developers, and creators converge to drive decentralization forward.”
Expected Topics and Themes
While the full speaker lineup is yet to be announced, the Web3 Summit 2025 will focus on industry infrastructure, technologies, and applications aligning with user needs and market demands. Based on the 2024 event and Web3 Foundation’s priorities, expect these key topics:
- Layer-2 and Scalability Solutions: Discussions on Optimistic and zk-Rollups, cross-chain bridges, and Polkadot’s parachain model to enhance blockchain scalability.
- Decentralized Identity and Privacy: Exploring self-sovereign identity and zero-knowledge proofs (ZKPs) for secure, user-controlled data, critical for Web3 adoption.
- DeFi and Tokenomics: Deep dives into decentralized finance protocols, stablecoin innovations (e.g., MiCA-compliant models), and economic models for sustainable ecosystems.
- Web3 Infrastructure: Insights into interoperability, like Polkadot’s role in connecting blockchains, and tools for dApp development.
- AI and Web3 Integration: Emerging use cases combining AI with decentralized networks, such as AI-driven dApps or tokenized compute markets.
Keynotes will feature pioneers from Web2 and Web3, bridging legacy and emerging tech. Kori Higgins, Web3 Foundation’s Director of Investor Relations, emphasizes the summit as a platform for “hackers, developers, and enthusiasts to hear and be heard,” ensuring diverse perspectives. Workshops and Nodespace sessions will let attendees shape discussions, from governance to NFT applications. Check

Section 3: The Power of Hackathons in Web3 Innovation (200-250 words)
The summit’s 72-hour Blockspace Symmetry Hackathon is a highlight, offering developers a chance to build and showcase Web3 solutions. In 2024, the hackathon attracted global talent, with projects competing for grants via a two-milestone prize structure. Hackathons drive Web3 innovation by:
- Fostering Collaboration: Teams whiteboard ideas, code together, and present to peers in a 24/7 hackerspace, sparking cross-protocol partnerships.
- Prototyping Real Solutions: Past hackathons birthed startups and dApps, from DeFi protocols to NFT marketplaces. Expect 2025 projects to tackle scalability, privacy, or gaming.
- Attracting Talent and Investment: Winning projects gain visibility with investors and Web3 Foundation grants, as seen with Polkadot’s $87 million 2024 treasury allocations.
