This is the second part of a more technical talk where Andreas explores Bitcoin script, with examples from the 2nd edition of Mastering Bitcoin, focusing on the use of conditional statements, flow control, guard clauses and time locks. The examples will include advanced multi-signature scripts, hash time lock contracts and asymmetric revocable commitments. Then he answers questions about Bitcoin’s quirky bugs, where Bitcoin differs from Ethereum at a scripting level, how SegWit works, how consensus rules change, and whether Bitcoin is more than just a currency.

CLARIFICATION: At 5:06, I say that SegWit hasn’t been activated yet. This video was recorded several months prior to SegWit’s activation in Bitcoin, which happened in the evening (EST) of August 23rd / early morning (UTC) of August 24th.
This talk took place at the San Francisco Bitcoin Developer (@SFBitcoinDev) meetup on April 3rd, 2017: https://www.meetup.com/SF-Bitcoin-Devs/events/238773843/
