| Mar 23, 2021 at 0:57 | comment | added | schroeder♦ | Your second part started off with "Regarding the take on limits of physics as the threshold, there was a lack of supporting sources:" That's not a part of the question. So, you might have something somewhere in all that that might have been helpful, but you did not write it as an answer. As I said, I removed the parts that were addressing other answers. Please make sure that your answers directly address the question. | |
| Mar 22, 2021 at 21:02 | comment | added | polarathene | The 3rd part regarding 256-bit was the only part referencing another answer due to a lack of information and what appears to be false claims. It was on topic with the answer I had provided with insights on 128-bit, and how security doesn't realistically increase beyond the limits I detailed. If you see no value in that information, I won't debate that any further. Anyone reading these comments will be aware of the removed parts of my answer and can look at the revision history if it'd be useful to them. | |
| Mar 22, 2021 at 7:43 | comment | added | schroeder♦ | No, I removed it because, as I said, it was a response to another answer and not an answer itself. You are saying that the calculations are different in this one claim, but that's irrelevant to the question. Your answer does not address the question. | |

The highest voted answer that you compare the first part of my answer to (which is all that remains with your edit), has different claims. 100-bit of entropy if bcrypt is in use seems somewhat specific yet vague.. At 1 attempt every 5 minutes, exhausts 24 bits entropy in approx 160 years (2^24 / (12*24)) / 365 = ~160 which can ignore any slow hash like bcrypt, the attack vector isn't slowed by it. By contrast I cited the bitcoin network hashrate, with all that processing power 100-bits exceeds a lifetime: (2^100 / 150e18 / (60*60*24*365))= ~268 years. 268 years at the current rate.

| Mar 22, 2021 at 2:44 | comment | added | polarathene | My answer provided a lot of insights with actual backing and math on limitations regarding energy costs or actual limits of physics, with linked resources to support those claims. You opted to remove that because a similar existing answer which lacks that information was available? | |
| Mar 21, 2021 at 23:51 | comment | added | schroeder♦ | And then what is a direct answer is little different from the highest voted answer. | |
