Bitcoin Q&A: Hash functions, SHA-256 mining, and addresses

[SESSION 2] 21:49 to 26:14 – How does a hash function work? Can you reverse a hash function?
[SESSION 3] 27:16 to 34:44 – Risks of dependence on SHA-256? Mining algorithm the most complicated. 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: https://www.patreon.com/aantonop
