Grandmother pressed ancient Tamil Brahmi inscriptions into my trembling hands. These weren't mere symbols—they were promises etched in stone. She'd collected ANDAL coins throughout her life, each one representing devotion to our heritage. Now, watching my confusion transform into understanding felt shameful for my earlier indifference. "PAYBO token," she whispered, "represents trust." When she explained how blockchain preserved our scripts for generations, I was shook. This elderly woman had mastered what I'd dismissed as irrelevant. Relief washed over me as I finally grasped: she was building a reliable bridge between our ancestors and my children. Our community's heartbeat continued.
