Leak Detect AI
The core focus: detecting metadata and side-channel leakage in decentralized AI training and inference clusters, with adversarial models for libp2p and IPFS transport.
FOSDEM'27 Developer Rooms around libp2p and IPFS are the core workshop events of the libp2p and IPFS Expedition — part of Expedition II across EU Open Source Week (Jan 25 – Feb 1) and Config Management Camp (Feb 1 – 3). Talks and collaborative sessions on modular, trust-aware, partition-tolerant networking for decentralized AI and Ethereum infrastructure. Security is the throughline.
Reimagining the future of modular, trust-aware, partition-tolerant networking. We investigate the next architectural evolution of libp2p and ethp2p, with security as the dominant lens.
Discovery beyond Kademlia for high-churn, agent-saturated peer networks.
Dissemination primitives for global-scale networks without coordination tax.
Identity, attestation, and value transfer for autonomous agents on p2p rails.
Coordination without global consensus under sustained adversarial splits.
Detecting metadata leakage at every layer — transport, routing, agent.
Secure channels with automated provisioning and cryptographic agility.
The core focus: detecting metadata and side-channel leakage in decentralized AI training and inference clusters, with adversarial models for libp2p and IPFS transport.
Hardening secure communication channels at the libp2p transport layer. Cryptographic agility, automated certificate provisioning, and Noise pattern evolution.
Trillion Dollar Security across Ethereum consensus and execution clients. Devp2p, discv5, and gossipsub hardening against partition and eclipse attacks.
Identity management and value transfer for autonomous agents, ephemeral devices, and adversarial actors operating across decentralized peer infrastructure.
Programmable trust layers for AI systems to coordinate directly across trustless P2P infrastructure without expensive global consensus.
Rethinking peer discovery for high-churn, multi-layered networks. Beyond Kademlia: structured overlays that survive adversarial conditions.
Scalable broadcast for global-scale networks. Reducing bandwidth, latency, and coordination overhead beyond traditional gossipsub.
Networking primitives that remain functional under sustained partitions, regional shutdowns, and adversarial internet conditions.
Synthesizing a unified architectural vision: modular, trust-aware, partition-tolerant, agent-native networking for the next decade.
Past contributions across libp2p, drand, IPFS and adjacent stacks have shaped how we approach secure open-source development for Ethereum's networking layer. The expedition draws directly on that operating experience — organizing OSS ecosystems in web3, running contributor cohorts, and building tooling for maintainer health.
A parallel thread of our work focuses on contribution intelligence, attribution and performance-based funding. We've been evolving libp2p's dependency graph and contribution attribution systems to support more accurate recognition of maintainers and contributors through Ethereum-style Deep Grants and RetroPGF funding mechanisms — using contribution data, performance signals, and ecosystem metrics to allocate funds and credits based on demonstrated impact.
Live cohort dashboard — contribution intelligence and impact signals for the current PLDG cohort.
Contribution attribution and cohort analytics platform for Protocol Labs Dev Guild programs.
Research corpus tracking libp2p adoption across the Ethereum ecosystem — clients, tooling, and integrations.
Experimental dependency management and proof-of-contribution using the Ethereum Foundation's Mopro SDK.
Performance-based funding pipelines that translate dependency-graph and contribution signals into retroactive allocations.
Past contributions and organizing work across Ethereum's core network dependencies — the foundation this expedition builds on.
We see meaningful alignment between this work and the broader opportunity around ecosystem intelligence, contribution measurement, and impact attribution — and expect these threads to inform sessions at the expedition.

The expedition is hosted in the FOSDEM'27 devrooms at the ULB Solbosch campus, Brussels, on 30 & 31 January 2027. It forms part of the second series of libp2p Expedition II, running through EU Open Source Week (January 25 – February 1) and Config Management Camp (February 1 – 3). The setting allows participants to collaborate in the open on the foundational problems of decentralized networking and security.

FOSDEM Devrooms are assigned to self-organizing groups to work together on open source and free software projects and to discuss topics relevant to a broader subset of the community. Most content takes the form of presentations. Proposals involving collaboration across project or domain boundaries are strongly encouraged.
