Dived deep into libp2p security this week with a new IP subnet diversity feature for the Kad-DHT, while fighting a few stubborn race conditions in the test suite. 3 PRs open and some automated maintenance on my Neovim setup kept the gears turning.

TL;DR

Security hardening took center stage this week as I focused on making our Kademlia DHT implementation more resilient against Eclipse attacks. Between drafting logic for IP subnet diversity and chasing down race conditions in the py-libp2p test suite, it was a week of high-leverage architectural thinking paired with the granular frustration of de-flaking async code.
