Authorities are offering a $1 million reward to anyone who can decode a mysterious 5,000-year-old script that has baffled experts for decades.

The enigmatic writing, known as the Harappan Script or Indus Valley Script (IVS), was created by the Indus Valley Civilization, which flourished over 5,300 years ago in what is now northern India and Pakistan. Although the civilization thrived for centuries before disappearing, it left behind thousands of artifacts inscribed with this undeciphered script, providing glimpses into their daily lives.

The first known discovery of the script was made in 1875 by Sir Alexander Cunningham, founder of the Archaeological Survey of India. He unearthed six symbols that didn’t match any known Indian writing systems. Since then, more than 7,000 similar inscriptions have been found, most featuring a central animal surrounded by a short sequence of characters. Despite extensive research, experts have yet to crack the code due to the lack of multilingual artifacts for comparison.

Unlike other ancient texts that often carry spiritual or religious meanings, scholars suspect the Harappan Script documents real-world activities. However, the challenge of deciphering it has proved insurmountable for linguists, archaeologists, and researchers worldwide.

In response, Tamil Nadu’s Chief Minister, Muthuvel Karunanidhi Stalin, has announced the staggering reward, promising to award $1 million to any individual or organization that can decode the script to the satisfaction of archaeological experts.

The announcement has sparked widespread interest, with engineers, IT professionals, and even retirees in India stepping forward claiming to have solved the puzzle. However, Rajesh PN Rao, a professor at the University of Washington and a leading expert on the script, remains skeptical. "Many claim they’ve cracked it and that the case is closed," he said, but so far, no one has met the challenge’s rigorous requirements.

The million-dollar prize remains unclaimed, waiting for someone to unlock the secrets of this ancient script—and potentially rewrite history.
