Bitcoin Q&A: Block capacity and embedded data

How many transactions can fit in a block, with or without SegWit? What other types of data can you put in a block? What is metadata? What is OP_RETURN? What is OpenTimestamps and what are the use cases?

More on OP_RETURN - https://en.bitcoin.it/wiki/OP_RETURN

These questions are from MOOC 9.6 and the June monthly Patreon sessions, which took place on March 23rd and June 24th 2018 respectively. Andreas is a teaching fellow with the University of Nicosia. The first course in their Master of Science in Digital Currency degree, DFIN-511: Introduction to Digital Currencies, is offered for free as an open enrollment MOOC course to anyone interested in learning about the fundamental principles.
