This POAP certifies that the holder participated as a hacker in the Aleph Hackathon, held during the Pop-Up City in March '26. Aleph Hackathon aimed to bring together builders from across Latin America and around the world to tackle real-world challenges using crypto and emerging technologies. Emerging technologies were shaping the next wave of real-world systems, from how financial infrastructure was built to how science was accelerated, complex workflows were automated, and autonomous systems were designed.

A single point for the entire builder universe | March 04 to March 26. Aleph March ’26 represents the fourth edition of Crecimiento’s pop-up city. Over the course of one month, Buenos Aires transforms into a focal point for crypto, AI, and emerging tech, bringing together builders, startups, investors, and ecosystem leaders.
