Devcon is an annual global event organised by the Ethereum Foundation. Devcon 8 ran from 3 to 6 November 2026 at the Jio World Convention Centre (JWCC) in Bandra Kurla Complex, Mumbai. The Devcon site describes the event as a place "where the people behind decentralized systems come together to learn, build, and connect." The next edition, Devcon IX, is planned for Lisbon in October 2027.
I attended mainly as an attendee. It was the centre of a week of events:
- DeFi Security Summit (1–2 November), where I helped organise.
- ETHIndia Conference 2026 (4 November), inside Devcon, where I helped organise.
- ETHIndia Institutional Open Doors Mixer (4 November).
- Dev3Pack Career Fair (6 November).
- ETHGlobal Mumbai (5–7 November), where I entered Bramble.
What it was like
The programme was large. There were many talks and booths, and a lot of side events around the main conference. The official site highlighted speakers such as Vitalik Buterin, Audrey Tang, Balaji Srinivasan, Justin Drake and Roger Dingledine. All sessions are published on the Devcon Archive, so you can watch the ones you missed.
The event was well organised, even at that size.
Most of the value came from the people. I met builders, founders and organisers, and the side events made it easy to continue a conversation after the main sessions ended.
Why it mattered to me
Devcon came to India for the first time, and I was in the city. I had spent the earlier part of the year at local Ethereum events, such as ETHMumbai. At the Open Source Summit India, I had explained Ethereum and Devcon to visitors at the Ethereum Foundation booth. Attending Devcon itself followed on from that.
