#p2p

DIG NAT traversal — abstract peer connection over UPnP/IGD, PCP (RFC 6887), NAT-PMP, direct (port-forwarded), with relay.dig.net as last-resort fallback. One connect() API; the traversal method is transparent to callers.

Serverless P2P team collaboration — invite-only workspaces, verified OIDC identity, channels, chat, files, and video over WebRTC. No app backend; signaling only helps peers find each other.

Process whiteboard engine & collaborative P2P editor — open source core of memorii whiteboard (binarii)

rats-search: BitTorrent P2P multi-platform search engine for Desktop and Web servers with integrated torrent client

Move files, open TCP tunnels, and share a terminal when a VPN is too much state for one job. DERP gets peers connected; tokens keep access scoped.

Pier — the broker (coordinator) reference implementation of the KOTVA standard: swappable, self-hostable, content-blind relays, adapters and gateways with a no-token billing model.

Baleen Engine is a high-speed, local-first, peer-to-peer Docker image sharing engine. It completely bypasses cloud registries and internet bottlenecks, allowing you to synchronize Docker images.

DIG Peer Exchange (PEX) — a well-defined, delta-based peer-exchange protocol (in the spirit of BitTorrent's PEX) used by the dig-relay introducer and between DIG Nodes to share known peers over existing mTLS connections: periodic added/dropped deltas, capped message sizes, no flooding.

Canonical DIG peer mTLS: the shipped public DigNetwork CA, per-peer node certs, rustls mutual-auth configs, peer_id = SHA256(SPKI DER), and the #1204 BLS-G1 cert binding.

Stoffel network (brand new) (super cool)

Forward ports between your own machines, peer to peer over iroh. No account, no public IP, no open inbound port.
