Project Kryptos
Dan Robinson, Matt Huang, 2026. Paradigm, 12 June 2026.
The buyer's announcement: Paradigm is "the new stewards of the Kryptos secret", has set up a SHA-256 plus cloud HMAC verifier so that no one at the firm sees the plaintext, charges $1 per K4 submission, holds the K5 ciphertext for later release, and runs a ten-puzzle challenge with $1,000 prizes.
What it's used for here
Primary statement of who holds K4 and how it is guarded.
