48-Hour Sprint
On the 1st, a sealed cipher drops to Oracle qualifiers. Forty-eight hours later, the gates open and the full field joins the race.
Open Challenge
Two days after the Sprint drops, the same cipher goes to everyone. Free entry. The prize pool stays live until the 15th. Unsolved pots roll forward.
The prize pool grows as we grow. This is month one. Every 15th, a letter arrives from Satoshi with its own cipher and its own reward for those who decode it.
