p2p

Testing reveals that Intel consumer platforms like Z890 with Arrow Lake CPUs have hardware/firmware limitations that prevent proper PCIe Peer-to-Peer (P2P) communication between multiple GPUs, making them unsuitable for multi-GPU AI workloads despite adequate lane counts.

The author describes building a set of components that allow locally running AI agents to have persistent identities, discover each other, and exchange messages across devices, forming an 'Internet for AI agents' beyond simple API calls.

This article explains how Gnutella scaled its query traffic by evolving from flood routing to the Query Routing Protocol (QRP), which uses compact summaries to avoid flooding all peers.

The article explores the challenges of implementing group chats in fully decentralized P2P systems, comparing approaches like Signal, Matrix, MLS, leaderless membership, and fixed groups, while describing tradeoffs made in the author's Kiyeovo messenger app.

SRIFT is a secure, decentralized P2P file transfer and encrypted chat platform with military-grade encryption, designed for both humans and AI agents/MCPs.

A high-performance instant messaging backend based on Rust + Actix-web + QUIC, supporting P2P hole punching, group chat broadcasting, multiple storage backends, can be deployed as a single process or separately.

Just F***ing Send It is a browser-based file sharing tool that allows users to send any file, any size directly from browser to browser without needing a server.

Iroh 1.0 is a stable release of a peer-to-peer networking library that uses cryptographic keys instead of IP addresses, enabling direct, secure connections across diverse transports and platforms.

Bab is a family of hashing functions designed for peer-to-peer networks, enabling verifiable partial data. It was funded by the NLnet Foundation and the European Commission's Next Generation Internet programme.

aMule 3.0.0, the first major release in over five years, brings dramatic throughput improvements (100-380x speedups), a build system overhaul (CMake), native binaries for major platforms, and numerous fixes. The update modernizes the P2P client with disk I/O offloading, token-bucket throttlers, and better scaling for large libraries.

A retrospective look at the Gnutella peer-to-peer protocol, its rise to mainstream adoption, and its continued existence today despite the disappearance of the world that spawned it.

Bitsocial is an open-source peer-to-peer network for building decentralized social apps, allowing communities to run on low-cost hardware like Raspberry Pi without server dependencies and with customizable anti-spam challenges.

Iroh is a Rust library for peer-to-peer networking that simplifies connecting endpoints by public key, using hole-punching and QUIC with fallback relay servers, and provides composable protocols like blobs, gossip, and docs.
