Suppose that Coin XYZ uses a 48-bit hash function to link the blocks, and it has an average block time of 3 minutes. Assume the current network difficulty is 4 M, and it is adjusted every 1200 blocks.(a) How many leading zero bits does the target hash have now if the initial target hash of the Genesis Block had 12 leading zero bits (the remaining bits are 1's)(b) Suppose that more miners join the network. Compute the next difficulty if the total time to mine the last 1000 blocks was 50 hours and find the corresponding next target hash in hex digits.
