How likely is a hard fork to increase the block size in the future? Under what conditions might that happen? What is being prioritised in the roadmap? Why implement Segregated Witness (SegWit) instead of "simply" increasing the block size limit? More on SegWit and capacity increase research: https://bitcoincore.org/en/2015/12/23/capacity-increases-faq/ More on Bitcoin hard fork research: https://bitcoinhardforkresearch.github.io/ These questions are from the February Patreon live Q&A and MOOC session 9.5, which took place on February 24th and March 16th 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.
