Kedarkantha Peak

Went first time trekking, to Kedarkantha peak. The elevation was around ~3800m, spent 3 days in the forest and then did river rafting in Rishikesh. Felt good to get away from code, from time to time.

Introduced AutoTLS in libp2p(-py)

Extended the TLS security module in libp2p(-py) to fetch CA authorized TLS certificates using the libp2p Auto-TLS client specification, rather than using self-signed ones. This will enable protocol execution via web-transport and browsers for libp2p(-py). PR: https://github.com/libp2p/py-libp2p/pull/1072

Implemented Floodsub from scratch

Wrote a Floodsub module for scratch in my experimental p2p stack. Learned a great deal how pubsub broadcasting systems behave under the hood with complex rust async designs. Getting ready to write Gossipsub now.

Rust async pattern -- single owner IO

Ran into an issue while building my experimental p2p stack in Rust – multiple parts of the code wanted &mut TcpStream. Turned out the design was improper. What worked for me was creating a single IO task owning the socket, with everything else communication via mpsc. Cleaner ownership, fewer borrow issues, and easier to reason about.
