• Some net_processing clean ups #20758 - next is splitting out orphan handling to a separate module #21148
• dandelion
  • considering "dandelion-lite" (stem for exactly one hop, the flood -- no p2p changes required)
  • question is whether that provides enough benefits to be worthwhile? answer: simulate and see!
  • gulia's updated https://github.com/gfanti/dandelion-simulations/tree/dandelion-lite ; some ensuing discussion on twitter https://twitter.com/giuliacfanti/status/1362963585471815680
• want to see erlay
• UASF/bip8 safety cf #19573

• Move application layer data from net to net_processing:
  • #19398 describes the high-level design
  • #21236 is the next PR in the series - Extract addr send functionality into MaybeSendAddr()
• Clean up addrman:
  • #20557 fixes some deserialization bugs introduced in #16702
  • #20228 makes addrman a top-level component, allowing ctor arguments to be passed directly from init and removing boilerplate code from CConnman
  • #20233 makes consistency checks a runtime option, so they can be used in unit/functional/fuzz tests.
• Review and help AJ's general cleanups #20758
• Review and help Carl's de-globalize chainstate manager #20158 (this is mostly in validation but touches the net_processing-validation interface a lot).

Seeking feedback on protection ratios for localhost vs onion vs I2P peers in the inbound peer eviction logic, see #20197.

• Protect onion peers in AttemptToEvictConnection + refactor and add test coverage: #20197
• Protect I2P peers in AttemptToEvictConnection + unit tests: #21261 (please review #20197 and #20685 first)
• Reviewing #20685 that adds I2P support, disabletx (#20726), and plan to review don't process unrequested txns (#20277)
