If you want to hear me talking about my recent paper "Ticket-based multi-strand method for increased efficiency in proof-of-work based blockchains" on the MoneroTalk/MoneroTopia podcast a few days ago, here is a link to that - it's at 3:16:35 into the podcast, those things are long 🙂

Good, fun discussion. The paper is here: https://arxiv.org/abs/2405.09531 - please let me know if you have any thoughts about the idea.
