I passed through Ministro Pistarini International Airport in Buenos Aires, Argentina and I got to mint this pretty POAP! Ezeiza is where Argentina’s first international flight departed in 1949—it was inaugurated by President Juan Perón and Eva Perón. This POAP was minted in Q4, 2025 as part of a campaign to offer precious collectibles to travelers at 18 airports around the world.

The ETHPrague Conference unites builders, thinkers, and visionaries to reaffirm blockchain's foundational ideals: decentralization, trustless collaboration, and open-access innovation. In an era of accelerating complexity, we return to cryptographic primitives, consensus mechanisms, and protocol-layer integrity — not as ends in themselves, but as tools to rearchitect societal systems for fairness, resilience, and sustainability. Together, we confront existential challenges — from centralized AI governance to climate instability. ETHPrague's mission is to steward community culture towards opening ourselves to outside criticism and facing crucial reality checks on what we build towards. The future remains unwritten. By grounding progress in Ethereum's bedrock principles, we choose neither dystopia nor utopia, but a protocol-powered realism — one where technology serves humanity's deepest needs, not its shallowest wants. This POAP was given to attendees of ETHPrague, held over 27 - 29 May 2025.
