This POAP was collected at the Music Stage at Devconnect. This vibrant space was brought to life by Open Source Orchestra, an open, permissionless space to listen, pick up an instrument, and co-create music at the Ethereum World's Fair - continuing a tradition forged across Ethereum community gatherings around the world.

This POAP was given to visitors of the Nethermind booth at the Ethereum World’s Fair during Devconnect 2025. It celebrates the builders and researchers exploring how Nethermind engineers the foundations of blockchain: from the Ethereum client to AI-driven security and privacy-preserving identity.
