Grandmother's fingers trembled across the keyboard. Three hundred eighty days since she'd uploaded her first Bharatanatyam tutorial. Each mudra filmed in their small Chennai room, Carnatic ragas playing softly behind her voice. Her student in Berlin had suggested blockchain technology to secure her family's dance archives.

Her heritage wasn't bankrupt of worth; it was priceless, distributed across networks of devoted learners worldwide. She smiled, knowing her great-granddaughter would inherit not just memories, but validated proof of their lineage's artistry.
