BackgroundThe Ethereum Foundation (EF) is a non-profit organization dedicated to supporting Ethereum and related technologies. The EF is not a company or even a traditional non-profit. We do not control Ethereum, nor are we the only organization that funds the critical development of Ethereum-related technologies. We are part of a large ecosystem of organizations, individuals, and companies that support Ethereum. Our mission is to do what is best for Ethereum’s long-term success.First introduced in 2022, Devconnect has evolved into a space for deep discussions, co-working, and innovation. This year, we aim to take it even further—transforming Devconnect into a "World’s Fair" for Ethereum, aiming at  fostering ecosystem progress, collaboration, and most importantly: adoption.  We want to create a Schelling point where the community and newcomers can gather to learn about, showcase, and experience real-world Ethereum applications.We want to support an ecosystem-wide effort and contribute to the local communities' goal to make Argentina the crypto capital of the world.
