Devcon 4 filled the Prague Congress Centre with about 3,000 attendees. The archive lists 149 sessions and 206 speakers; the programme ran from Ewasm and the EVM roadmap to Eth 2.0 research, front-running defences and Mist. Jonathan Mann opened and closed the event with a song. Source: Devcon Archive (archive.devcon.org), checked 4 Sep 2026.
