I passed through Ministro Pistarini International Airport in Buenos Aires, Argentina and I got to mint this pretty POAP!

This POAP was minted in Q4, 2025 as part of a campaign to offer precious collectibles to travelers at 18 airports around the world.

Around October 30, 2025, Beaconcha.in data provided by Hildobby, showed that the share of validators on the Ethereum beacon chain operated by Lido had fallen below 22%. 22% is regarded as a critical threshold for entity size, because larger entities represent a centralization and governance risk to the network. We welcome Lido as an aligned actor and we celebrate the robustness of the beacon chain.
