Excellent Bitcoin and Blockchain Video
I went for a 63 mile (metric century) bike ride a week ago while listening to five hours of podcasts on blockchain and this video below was more succinct and clear then anything I heard on my ride. This deeper dive into blockchain was prompted by a very technical dinner conversation on blockchain that I had when I was at Top Shops at the beginning of September.
This is an excellent video on Bitcoin and Blockchain. It balances just enough of the behind the covers to understand what is going on, without getting into the lower bit-level mathematics of cryptography. This gets into how blockchain can be compromised (51% attack), but shows enough details on why that becomes simply unfeasible. There is an excellent video on SHA-256 (Secure Hash Algorithm 256 bits that the creator, 3Blue1Brown, discusses.
Yes, I am a geek if I listen to five hours of blockchain podcasts :-)
