Just read Optech #362—pretty cool stuff this week. Josh Doman dropped a library that shrinks output script descriptors by ~40% so they fit better in QR codes, which is super useful. Also, there was a review meeting on a PR from glozow that tweaks TxOrphanage logic to prevent DoS while making sure every peer can resolve at least one big orphan package. If you're into this kind of thing, there's a recap podcast too and a discussion coming up on Tuesday at 16:30 UTC.
