Ping RTT benchmarks b/w rnet and libp2p

Mon, 13 Apr 2026 00:00:00 +0000

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

Introduced Prometheus/Grafana metrics to libp2p(-py), improving network observability for the core services like Gossipsub, Kad-DHT and connection lifecycle.

Introduced AutoTLS in libp2p(-py)

Mon, 02 Feb 2026 00:00:00 +0000

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).

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.

Got selected for Protocol Labs Dev Guild.

Excited to go deeper into p2p infrascture and libp2p ecosystem.
