#BUIDL your new idea in front of Ethereum founders, blockchain industry and enthusiastic audiences at ETHDenver's #BUIDLathon.


What is #BUIDL


Propagated at ETHDenver 2018 is a misspelling of the word "Build."

#BUIDL is a call to blockchain enthusiasts to build and contribute to the advancement of the blockchain ecosystem (decentralization), rather than passively HODLing (HODL Bitcoin), and waiting for the price to go up.

ETHDenver is focused on #BUIDL culture rather than HODL culture. We cannot just HODL our way into the future, we must #BUIDL the decentralized future.

A “#BUIDLathon” is a celebration of #BUIDL culture and values:

  • It’s an event where #BUIDLers from around the world come together to solve problems and pitch their ideas to the community. SporkDAO #BUIDLathons are also run in parallel with a community innovation festival.

  • It’s a magical time when talented, impactful, and genuine people get to hit mute on the usual grind of spammers, scammers, and noise. They let their guard down to explore new ideas and make surprising connections. Engaged #BUIDLers leave #BUIDLathons with new skills, understanding, and relationships to supercharge their efforts “in the real world.”

At ETHDenver 2024, #BUIDLers will form teams of 2 to 4 and spend up to 9 days #BUIDLing to their unique web3 visions. #BUIDLers have the 24/7 support of peers, mentors, stewards, and sponsors. They are the stars of ETHDenver’s Community Innovation Festival; their projects, teams, and relationships will propel web3 forward long after the 2024 #BUIDLathon has concluded.
