Protocol Labs Research

The Protocol Benchmarking & Optimization Team (ProbeLab) is on a mission to measure the performance of Web3 network protocols, benchmark protocols against target performance milestones, and propose improvements to their core design principles.

Our work focuses on internal network protocol logic, as well as cross-protocol interoperation and network architecture. We start from the protocol as an independent entity and dive into its mechanics. We then investigate the exogenous factors that influence the performance of the protocol, as well as the influence that this protocol has on other parts of the system. We specialize and work on network-layer protocols.


  • You can find our Completed, Ongoing and Future projects in ProbeLab’s Notion page, where we currently organize our work.
  • Our network measurement work and results lives in this GH repository: You can open issues and submit PRs for items of interest to your project/product.
  • Our latest results are posted on the “Results” folder of the same repository.
  • Our latest ACM Sigcomm 2022 paper includes a comprehensive description and internal details of the IPFS architecture, as well as a summary of our latest measurement campaign.


  • Yiannis Psaras (Lead)
  • Guillaume Michel (Research Engineer)
  • Many wonderful external collaborators which you will find in the Notion page linked above.

Where to find us

  • We frequent in the #probe-lab channel on the IPFS Discord Server
  • We hold bi-weekly Office Hours, where we discuss items related to network measurements, protocol design and network architecture, primarily focused around IPFS, libp2p and occasionally Filecoin. Reach out to us if you want an invite.

Design and evaluation of IPFS: A storage layer for the decentralized web
Recent years have witnessed growing consolidation of web operations. For example, the majority of web traffic now originates from a few organizations, and even micro-websites often choose to host on large pre-existing cloud infrastructures.

Decentralized internet, networks, protocols, and systems (DINPS) workshop at IEEE ICDCS 2022: call for contributions
Call for Papers Announcement: Workshop on Decentralized Internet, Networks, Protocols, and Systems Website: Submission Deadline: 5 March 2022 In June 2021, we ran a workshop on “Decentralizing the Internet with IPFS and Filecoin” (DI2F) alongside IFIP Networking 2021 to establish a forum for academics, researchers and developers to share their expertise and latest findings on decentralized storage, IPFS, libp2p, and Filecoin.
