Here you can watch the first 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.
Those examples will include you in advanced multi-signature scripts, hash time lock contracts, as well as 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.
