Ethereum’s resilience is a collective effort.
Four days in Mumbai brought together builders, maintainers and researchers around one shared question: how do we make open networks more resilient?

// four days · shared momentum
Participation and activity figures from the libp2p team’s four-day Devcon recap.
// beyond the numbers
Participation in libp2p developer initiatives spanned almost every continent, with Antarctica the exception. Builders, researchers, founders and institutions brought diverse perspectives and technical expertise to Mumbai.
Meetings and conversations explored scaling institutional adoption of Ethereum and strengthening its underlying infrastructure. Community feedback helped shape the next steps for ecosystem development and support for builders.
AI agents and agentic infrastructure, quantum-resistant cryptography, zero-knowledge proofs, privacy-preserving technologies, formal verification and protocol correctness were central themes, alongside Ethereum consensus clients and decentralized networking.
Protocol resilience, interoperability and developer experience sparked constructive feedback and promising follow-ups. Beyond the numbers, the openness to collaboration and quality of technical discussion stood out.
The team’s Devcon recap reports that the EF Consensus Clients ↔ libp2p coordination cell was formalized around security initiatives, providing a focus for continued cross-team collaboration.
// on-stage workshops & talks · day 1
At @EFDevcon 8’s Resilient Networking Hub, we brought together perspectives on @libp2p, @Ethereum consensus clients, implementation diversity, network security, and the path toward post-quantum readiness.

What happens when permissionless networks are pushed to their limits?
At Devcon 8, we shared real-world lessons from libp2p deployments like Qaul and Zemzeme, exploring how P2P networks recover from severe connectivity restrictions, censorship, and infrastructure disruptions.
From regional nodes and discovery mechanisms to autorecovery and network observability, resilience is something we must build, measure, and continuously improve.
DEVCON 8 · PERMISSIONLESS NETWORK RESILIENCE
Building networks that stay connected when it matters most.
// ecosystem outcome · formal methods & protocol engineering
Presented at Devcon 8, leanp2p aims to build a libp2p implementation in Lean 4, initially targeting the Ethereum consensus layer.
An exciting initiative from @leolarav, @invisiblgarden, Resilient Networking Hub and @ethpadthai and collaborators.
The project is currently in its bootstrap phase, with its foundational package structure, build infrastructure, and vector-based verification framework in place.
Leo also conducted a workshop at the Resilient Networking Hub alongside @manusheel and @adust09 on building open, resilient networks with libp2p. The team also conducted a hackathon.
An exciting direction for the ecosystem: exploring how formally verified systems and rigorous protocol engineering can strengthen the foundations of decentralized infrastructure.
Congratulations to Leo and the entire Invisible Garden and EthPadThai team!
// ecosystem outcome · simulation & observability
Another key outcome of Devcon 8: improvements in Luminar, a real-time P2P network simulator with live visualization of GossipSub, DHT, and fault injection.
Fifty simulated peers run GossipSub v1.1 with P1–P4 peer scoring. Inject Sybils, an eclipse or a partition and watch the score bite — live or from a recording.
Watch messages spread hop by hop across the mesh as fifty peers gossip in real time.
GossipSub v1.1 P1–P4 scoring you can watch bite: misbehaving peers get pruned within heartbeats.
Inject Sybil attacks, eclipses and network partitions to see how the network defends itself.
Explore DHT behaviour and replay recorded attack scenarios such as a Sybil eclipse.
A hands-on way to build intuition for how P2P networks behave under stress — useful for researchers, educators and protocol engineers alike.
// across the four days
Highlights from the four-day program — from protocol foundations and research to decentralized media and practical contribution.
DAY 01
November 3
The opening day connected networking foundations with verifiable actions, formal verification and practical infrastructure work. The on-stage Building Resilient Ethereum workshop brought the wider protocol conversation into focus.
DAY 02
November 4
The program explored gaps in protocol resilience alongside hands-on work in agentic P2P infrastructure, formal verification, libp2p and IPFS.
DAY 03
November 5
Decentralized Media Day put publishing, distribution and ownership at the centre of the conversation, with Swarm-focused workshops, talks and live demonstrations.
DAY 04
November 6
The final day’s official program connected post-quantum migration, observability and formal methods with practical contribution pathways and protocol security.
// the shared takeaway
Networking, consensus, implementation diversity and security are connected challenges. Bringing those perspectives together helps us ask better questions — and keep building together beyond Devcon.
Thank you to Ornella, Jude, Satyaki and the entire Devcon organizing team for a thoughtfully curated gathering — and to everyone who attended the Hub, contributed sessions, shared their work and joined the workshops. Your learning, feedback and constructive pointers are helping shape what comes next.
