On a windy day in March, artist Jim Sanborn greeted visitors at his studio on an isolated island in the Chesapeake Bay. The visitors made him sit in front of a laptop, and he wrote a secret message. They compressed the message using a unique hash function, sent it to the cloud, and wiped the laptop clean. Sanborn hoped this action would lead to his release. But did you do it?
This is the latest twist in the story Kryptosthe famous Sanborn sculpture that has been located outside the CIA headquarters in Langley, Virginia, since 1990. The artwork is a 9-foot, 11-inch-tall S-shaped brass curve into which Sanborn perforated four panels of ciphertext. Professional and amateur cryptanalysts alike have been trying to crack the code ever since. Within a decade, three of the plates were solved, but the fourth plate of 97 letters, known as K4, was not solved. For decades, Sanborn has been offering solutions, all of them wrong. On the one hand, the secret of his letter was a remarkable reflection of the work of the intelligence community. On the other hand, it was a burden. In recent years it has been infused with cockami, AI-assisted submissions.
Sanborn has had enough. The 80-year-old artist also wanted to boost his retirement fund. So in 2025 he arranged an auction house sale The answer to K4 — plus the solution to K5, an additional panel that has not been disclosed. In November, the highest bidder paid Nearly a million dollars For the prize, which included a scale model of the statue and other ephemera. Sanborn received $770,000. The identity of the winners and their plans for Kryptos have been another secret until now.
Today the winner emerges from the shadows. Paradigm, a venture capital firm focused on cryptocurrencies, is tasked with vetting the guesses until a genius finally solves the puzzle.
Like almost everything in the Kryptos saga, last year Auction It had some wild plot twists. Weeks before the deadline, researchers Garrett Kubiak and Richard Byrne told Sanborn that they had found the K4 script. The Smithsonian has Kryptos materials in its archives, and Byrne went to photograph the holdings. Kubik discovered in the pictures that the artist had taken them unintentionally K4 plain text included In his papers. Ultimately, the researchers agreed not to publish their solution, the Smithsonian closed the archives, and the auction continued as planned.
So who are these bidders? Paradigm is led by one of the founders of Coinbase. The fund backs cryptocurrency-related companies, builds open source software projects, and has recently expanded into artificial intelligence and robotics — a good choice given that bitcoin is in free fall and blockchain technology has lost its hype.
