Bitcoin Q&A: Hash functions, mining, and addresses

Bitcoin Q&A: Hash functions, mining, and addresses How does a hash function work? Can you reverse a hash function? Are there risks of dependence on SHA-256? What is the purpose of double hashing to produce the address?

These questions are from the second and third sessions of MOOC 12, which took place on September 19th and September 27th 2019 respectively. If you want early-access to talks and a chance to participate in the monthly live Q&As with Andreas, become a patron:
