Title: Does prob. of finding a solution for a block depend on its contents at all? Post by: jwputrl on October 18, 2014, 11:19:04 AM Am I right in thinking that a miner will have the same chance of finding a solution for a block, whatever transactions (or anything else) it contains?
I'm saying this as I assume it doesn't matter what the input into the hash is, the chances of getting a solution are the same, for a given difficulty level.

Is this uncertainty you refer to because nobody knows for sure how sha256 actually behaves? So if a miner were to work that out it is possible they could select contents to increase chance of finding a solution, but if they don't they can't? Pls feel free to point me somewhere else so i can educate myself.

Post by: Spartan_Miner on October 19, 2014, 09:39:37 AM I noticed that when that BearWhale did that massive sell-off, duration times went up in a big way. Was there a relation, or simply a coincidence? (I don't believe in coincidences)

What we don't know is if someone out there has discovered a way to shortcut/cheat the SHA256 process without the rest of the world finding out. |
