At ETHConf 2026, most activations relied on technical demos and presentations. @ValleyEcosystem dropped a physical cabinet on the floor with a leaderboard, and attendees kept coming back. The reality about Web3 onboarding: Friction kills adoption. If your first step is forcing a player to download a wallet and learn crypto terminology, you've already lost them. Valley Arcade proved that competition and tangible rewards drive engagement far more effectively than technical explanations. People don't want to be "onboarded" into blockchain. They want to have fun. If the gameplay loop is compelling, the onboarding happens seamlessly in the background. What was the most important takeaways from @ethconf ?
