Reflections exercise

What we learned so far?

bg right:30%


Answer the following questions

  • How could PoW be used to combat spam?
  • Why do some backup solutions make use of public key cryptography?
  • Why do software devs publish file hashes?
  • Why is asymmetric cryptography used for "COVID vaccination certificates" printed on paper?

Take the chance to be a bit --verbose!
