Murch and Clara discuss:

• Building a valid block 101 (5:45)
• The current getblocktemplate algorithm (11:35)
• Child pays for parent (13:40)
• Is there something better? (15:45)
• How easy would it be to guess the next block? (27:25)
• Do we have a better idea than initially mining an empty block? (29:25)
• Empty blocks and SegWit (33:45)
• How to improve on the candidate set algorithm e.g., linear programming (35:00)
• Why should Bitcoin Core have better block building? (37:00)
• How to compare different block building techniques (38:55)

Thanks to Caralie for the sound engineering.
