Original authored description

DIGITAL ASSET DESCRIPTION The RWA tied to 250 Greenwich Street, New York, NY 10007 represents ownership exposure to the National September 11 Memorial & Museum, one of the most significant institutions of remembrance in the United States. Unlike assets whose importance is measured through commerce, finance, or development, this institution derives its significance from the preservation of memory itself. What makes this asset unique is its connection to one of the defining events of the twenty-first century. The institution exists to document, preserve, and communicate the history, impact, and human stories associated with September 11, 2001. Through education, historical records, artifacts, and public engagement, it serves as a permanent repository of collective memory. The property occupies a rare position within the national landscape because it functions as a place of reflection rather than transaction. Visitors from around the world come not to conduct business or acquire goods, but to understand, remember, and honor a moment that reshaped lives, communities, institutions, and history itself. The blockchain connection is direct. Both systems preserve records across time. One safeguards historical memory within the physical world, while the other safeguards ownership and provenance within the digital world. Each serves as a mechanism for ensuring that important information is not lost. The significance of this address is that it serves as a permanent institution of remembrance, preserving the history, lessons, and human stories of one of the most consequential events in modern American history. ## Archived & Preserved by Jacob Alan Ervin Lovaas🇺🇸🎩 June 11, 2026
