  1. So the answer is to increase the amount of work required.
  2. Normally, we want to use computation to reduce work,
  3. but here the goal is to make this amount of work to find a bitcoin
  4. to be stable, to be fairly predictable, and to be about 10 minutes long.
  5. And so, we could do that with just one hash function
  6. by reducing the value of the target.
  7. That would require changing the target more frequently
  8. and using more zero bits in the target.
  9. The alternative is to make it harder to compute each value of x,
  10. and that's what the two hash functions do.
