b. [6 points) Find the average time for mining a block for each of the following hash targets. Measure the time in terms of both the number of hash computations as well as in seconds on your machine. Report your results as an average for mining 10 different blocks. Fill the table below. 1. Hash target = 28 2. Hash target = 212 3. Hash target = 216 Hash Target Average number of hash computations to mine a block (average over 10 blocks) Average time in seconds to mine a block (average over 10 blocks) 28 = 256 212 = 4,096 216 = 65,536 b.
