Technical specifications for the libp2p networking stack, defining wire protocols, addressing, and core abstractions for peer-to-peer applications.
libp2p/specs is the official repository containing technical specifications for the libp2p networking stack. It defines wire protocols, addressing conventions, core abstractions, and processes for building modular peer-to-peer network applications. The specs ensure consistency across multiple language implementations by providing implementation-agnostic reference documentation.
Protocol engineers, library maintainers, and developers implementing or contributing to libp2p in various programming languages who need authoritative specifications for interoperability.
It provides the single source of truth for libp2p's network-level behavior, enabling consistent cross-implementation development and serving as a coordination point for evolving the protocol suite through a structured specification process.

Serves as the single source of truth for libp2p's wire protocols and core abstractions, ensuring consistency across multiple language implementations as stated in the overview.
Covers a wide range of protocols including Kademlia DHT, Noise/TLS handshakes, GossipSub, and WebTransport, detailed in the specification index for modular P2P networking.
Includes a defined spec lifecycle and document format, facilitating organized evolution and contributions to libp2p standards, as outlined in the Specs Framework section.
Enables flexible peer-to-peer communication by decoupling application logic from underlying network complexities, supporting various transports like QUIC and WebRTC.
The README explicitly states that specifications are currently incomplete and under revision, leading to potential gaps and uncertainty for implementers relying on stable docs.
Requires deep understanding of protocol buffers, network protocols, and P2P concepts, with no direct implementation code provided—only specs, making it challenging for newcomers.
Developers must bridge to separate language implementations for practical use, and inconsistencies or lag in adopting new specs can arise, as noted in the status section.
