Devcon 5

About the Event

The last Devcon before the pandemic pause. Featured community-run outdoor stages and an experiential Park area alongside the main tracks.

Devcon 5 in Osaka carried more content than any edition before it: 306 recorded sessions from 419 speakers, plus the first community-run outdoor stage and the experiential Park area. The opening ceremony was followed by the Ethereum Roadmap 2020 session; the programme leaned on Eth 2.0, the EVM roundtable, bridges and DeFi.
