Devcon 8 by the numbers: 2,062 questions and 7,574 votes and reactions across 217 sessions in Mumbai: 9.5 questions per session on average, median 7. Where sessions took questions live, 43% were answered on stage. That's the point of Meerkat: everyone in the room can ask and vote, not just the first hand up, so the questions people care about rise to the top. The ones answered on stage were rated more relevant than the rest, and Meerkat's AI rated 83% of all questions related to the talk. Thank you @EFDevcon, every speaker who took the room's questions, and everyone who asked. Running an event? DM us. @ethereumfndn

You can't prove your code is correct without first defining what it's supposed to do. At @EFDevcon, @SagivMooly discussed why writing the informal specifications remains one of the hardest challenges in formal verification.

To everyone who came to Devcon 8 ๐ŸŒ You sat on the floor around the music. You sang with strangers. You stayed for one more song, then ten more. Builders, dreamers, first-time drummers: you were the orchestra. Find yourself in the photos ๐Ÿ“ธ๐Ÿ’› See you on the road to Lisbon ๐Ÿ‡ต๐Ÿ‡น

Devcon 8 Mumbai: Top 10 Takeaways ๐Ÿ‡ฎ๐Ÿ‡ณ 1. Ethereum Next Phase: Focus on scalability, security and simplifying the protocol. 2. @VitalikButerin Vision: Building @ethereum future around scalability, privacy and decentralization. 3. Zero-Knowledge (ZK): ZK technology is becoming central to Ethereum's future. 4. AI + Blockchain: AI agents could become major users of decentralized networks. 5. Quantum Resistance: Preparing Ethereum for future quantum computing threats. 6. Privacy Matters: Privacy and user consent are becoming core priorities. 7. Security First: Stronger wallet, exchange and protocol security is essential. 8. Real-World Applications: More focus on solving real problems beyond crypto trading. 9. India's Developer Ecosystem: India is emerging as a major hub for Ethereum builders. 10. Open-Source Development: More emphasis on community-led innovation and decentralized building. Ethereum future is about more than DeFi and tokens. It's about building secure, private, scalable and verifiable systems for the real world. I enjoyed it a lot! Loved meeting new people and connecting with the Ethereum community. @EFDevcon happening in India for the first time made the experience even more special. ๐Ÿ‡ฎ๐Ÿ‡ณโค๏ธ

for young builders of India ( read this only if you are not doom-scrolling rn ) today you all leave home after @EFDevcon don't be back at next devcon the same way you left this one. if you had a good time at @EFDevcon , chances are - you met inspiring professionals of @ethereum - you attended eye-opening talks & workshops - you witnessed deep discussions on core tech - you overheard interesting conversations by the coffee counter, and as a result: you were MOTIVATED & INSPIRED inspired to build, learn, to gain subject matter expertise, be able to communicate/debate ideas clearly whatever the inspiration is.... I want you to HOLD ON TO THAT MOTIVATION for as long as you can... coz it won't last because Motivation &inspiration are fleeting and perishable states - they will vanish asap. and this is especially true for builders in India where most of us don't have the luxury of dedicating all our time to future & tech, while some hv responsibilities, priorities, families to tk care of. and then there are uncertainties of the current markets, AI Psychosis, and if nothing else, inferiority complex from CT doom scroll.... everything designed take away your inspiration that you are feeling right now. So, what do you do? TAKE ACTION And channel this motivation/Inspiration asap And then make it a practice to be biased towards ACTION. I literally don't care how small of win that action gets you ( or doesn't ) , but take some action for god sake - the person that inspired you at devcon, shoot a DM/email - the concepts that sparked your curiosity, start reading - the ideas that seemed cool, build a prototype with AI to explore - the experiences you found unique, force yourself to sit and write about it don't let @EFDevcon be just another event you attended don't let the lessons, learnings and inspiration go in vain don't be back at next devcon the same way you left this one - return better TAKE ACTION

Social media often rewards the most negative takes But if you look around @EFDevcon youโ€™ll see active and engaged community hubs, people having great conversations with speakers and projects alike and a quiet and productive co working corner too for attendees. Haters hate Builders build
