Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      TIL the second law of thermodynamics says enumerating all the possible 256-bit encryption keys (even without attempting them) would require at minimum all of the energy of 137 billion supernovas.

      Until we introduce someone named Moore to the equation...

      This is the hard physics lower-bound of energy needed.

      It won't hold up much longer, 256 will be obsolete within 5-10 years.https://www.reddit.com/r/Bitcoin/comments/24zwsr/how_many_qubits_would_it_take_to_break_bitcoins/ …

      Bold move to bet on the second law of thermodynamics become obsolete.

      Betting quantum computers get around the limitations of transistor based computers ;) Fun fact though, thermodynamics says energy can't be destroyed but every time a photon redshifts because of the expansion of the universe, a bit of its energy is destroyed.

      The number isn't based on transistors. It's based on the information theoretic energy lower-bound for a particle to irreversibly change information states.

      With ~1300 qubits the quantum system can be in a superposition of ALL possible states in the 256 bit key and resolve to the correct private key. I think the out for us is the word "enumerate", quantum systems don't enumerate they are basically everything and then the answer.
