2026-05-28 Update: Prerequisite item libp2p now has an active PR (#59 by digitalSloth, opened May 20 2026) under review on zenon-network/go-zenon. This is meaningful forward progress on the blocker. Narwhal & Tusk itself has no assigned developer or open PR. Status remains planned until libp2p merges.

Long-tail item. libp2p is a prerequisite. No active PR or developer assigned as of May 2026. Original Q1 2026 ETA passed with no progress.
