When there's a 40 (mars) or 80 (jupiter) minute delay that's guaranteed, it sounds like a unique form of a time lock. Put your private pgp key in a 24 hour time delay circuit and guarantee that no one can do a decryption in the interim (long as it's the only copy).

I wonder if 50 years from now there's going to be a blockchain based on that technology (as opposed to the computation or storage based blockchains we have now).
