I am Abhinav, a strange loop …

Did an RTT benchmark comparing my experimental p2p stack rnet vs libp2p rnet → ~220–300μs rust-libp2p → ~130–250μs py-libp2p → ~300–400μs Same machine, loopback libp2p: TCP + Noise + Yamux rnet: TCP + custom security (Deffie-Hellman based key-exchange) + Mplex rnet lagging behind by ~60μs implementation overhead from rust-libp2p rnet: https://github.com/lla-dane/rnet/

Built a secure transport layer today for my p2p stack. Raw streams -> negotiated -> encrypted (Deffie Hellman + ChaCha20Poly1305). Feels good seeing the pieces come together. PR: https://github.com/lla-dane/rnet/pull/2

Introduced Prometheus/Grafana metrics to libp2p(-py), improving network observability for the core services like Gossipsub, Kad-DHT and connection lifecycle. PR: https://github.com/libp2p/py-libp2p/pull/1199

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.

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

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.

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.

Bought a Raspberry PI 5. Planning to do some networking experiments and small infrstructure setups.

Started writing an experimental p2p stack, rnet inspired from libp2p specs, to dig deeper into rust and core p2p mechanics.

Attended an IRL hackathon in New Delhi. Built a p2p federated learning platform using libp2p(-py), Akave-O3 and Hedera hashgraph. Won the Filecoin/Akave track at ETHNewDelhi'25.
