So, I have converted all the r values into binary and compared each one. Here are the results. These are the r values from the signatures of the address containing just over 2 BTC. Is the number of bits sufficient?


Comparison between r1 and r2:
Number of fixed (common) bits: 132 / 256
Ratio of fixed bits: 0.5156
--------------------------------------------------
Comparison between r1 and r3:
Number of fixed (common) bits: 125 / 256
Ratio of fixed bits: 0.4883
--------------------------------------------------
Comparison between r1 and r4:
Number of fixed (common) bits: 131 / 256
Ratio of fixed bits: 0.5117
--------------------------------------------------
Comparison between r1 and r5:
Number of fixed (common) bits: 132 / 256
Ratio of fixed bits: 0.5156
--------------------------------------------------
Comparison between r1 and r6:
