- Divide by 115792089237316195423570985008687907853269984665640564039457584007913129639935, which is the maximum value of a 256-bit number. You now have the probability of a single hash solving a block
- Take the reciprocal of the probability to get the average number of hashes to solve a block.
- Divide the average number of hashes by your hash/s (not khash/s) to get the average number of seconds required to solve a block.
***(I HAD AN ISSUE WITH THESE INSTRUCTIONS because the current target is not a decimal number)*** we need a step to convert the hexadecimal target to a decimal number*** the target might not even be a hexadecimal value because when i converted it, and did the math I didnt get the current difficultyWhen looking at steps 1-3 they say:
Step 1 is get current target
Step 2 is divided current target by max target
Step 3 is take reciprocal
Why not say:
Step 1 - get max target. Also, instead of writing out that number write out 2^256 for brevity.
Step 2 - get current target.
Step 3 - convert the current target from hexadec to decimal.
Step 4 - divide step 1 by step 2 (max target/current target), which is equivalent to the average number of hashes needed to solve a block and is also the current difficulty.
Step 5 - Divide the average number of hashes by your hash/s (not khash/s) to get the average number of seconds required to solve a block.
(Additional Info) - The recipricol of step 4 is the probability of a single hash solving a block
