It took roughly 10 minutes for all of the miners (doing a combined 700,000,000 giga-hashes per second) to find the above hash which has enough leading zeroes (17) to meet the difficulty requirement of the network at that time. Since the remaining digits after the first 17 leading zeroes could have been anything, there are 16^47 (i.e.16^(64- 17)) possible hashes that could have been found which would have satisfied the Wildly in ove.

If you have signatures (R ₁ ,s ₁ ) and (R ₂ ,s ₂ ) for message M, then you can turn them into one signature (R ₃ ,s ₃ ) = (R ₁ *R ₂ , s ₁ + s ₁ + x*R/s ₁ = h(M ₂ )/s ₂ + x*R/s ₂ x*(R/s ₁ – R/s ₂ ) = h(M ₂ )/s ₂ – h(M ₁ )/s ₁ x = (h(M ₂ )/s ₂ – h(M ₁ )/s ₁ ) / (R/s ₁ – R at PlayStaytion 3’s key was hacked in 2 0 1 0.

Theoretically, running an algorithm over and over again over a set of ra ndom inputs (exactly w hat mi ning is), could provide insight into p atterns prod uced by the algori thm, thereby allowing one to prove whether or not it’s broken. However, th is insight wou ld only come through statistical analysis of data gathered, and since most of the data is thro wn out — c hash fun ction, so my que stion was a little flawed to begin wit h, but the amount of ti me it would take to brut e-force a single SHA25 6 hash is (currently) much t oo long even with the most advanced AS IC miners available today.
