  1. With the above code, I’m getting prevHash : 30 for the first block while printing the block data. It should be empty right?

    I’m using the below function to print the data of the block :

    func printBlockInformation(block Block) {
    fmt.Printf(“\ttime: %s\n”, block.timestamp.String())
    fmt.Printf(“\tprevHash: %x\n”, block.previousHash)
    fmt.Printf(“\tHash: %x\n”, block.hash)

    }

    Can someone please help?

  2. What is the point of the proof of work step? Why can’t you simply calculate the hash once, and be done? Why do you have to waste CPU cycles on a loop, calculating millions of hashes just to prove that you did work? What is the practical point of the proof of work step?
