Web3 Event Guide — major Web3 and crypto conferences | web3event.org
How the hackathon-style format at events like ETHDenver works for a visitor: building in a fixed window, forming teams, taking mentor input and demoing the result.
ETHDenver's '#BUIDL' framing places building at the center of the event: the official site describes a 'BUIDL City' gathering innovators and builders, which means the program is designed around producing something during the window.
For a visitor this changes the shape of the days. Instead of moving between stage talks, you join or form a small team, pick a problem, and spend the core hours writing and integrating code.
On narrow screens, swipe or scroll the plate sideways.
Mentors circulate during the build window; their role is to unblock teams and pressure-test approaches rather than to lecture. The closing demo is where the work is shown to the room.
The format rewards preparation before arrival: a working development environment, a clear idea shortlist and a team plan save the first hours of the event for building rather than setup.
Hackathon and conference formats are not interchangeable. A conference visitor consumes a program; a hackathon visitor produces a project — the same event name can host either, so read the format field in any listing carefully.
