Hi there,
I am Max, a software developer interested in distributed systems, type theory
and consensus. Welcome to my little island on this crazy thing called The
Internet.
You might enjoy browsing through my list of resources I consider worth
sharing, get some inspiration from the numerous summaries of past
reading group sessions that I organize or simply scroll through my
resume to see what I am up to lately.
You can best reach me via e-mail: mail@max-inden.de.

Hole punching in libp2p —
We have been working on hole punching support in libp2p for the last year. It finally landed in the Go and Rust libp2p implementation.
Read all about it on the IPFS blog: https://blog.ipfs.io/2022-01-20-libp2p-hole-punching/…

Peer-to-peer hole punching without centralized infrastructure —
Gave a talk on hole punching in libp2p at FOSDEM 2022.
Peer-to-peer hole punching without centralized infrastructure
How libp2p can traverse NATs and firewalls without coordination through central STUN and TURN servers.
libp2p is a universal, cross-platform, multi-language, modular peer-to-peer networking library powering multiple large-scale networks, for example IPFS.
In the first part of the talk we’ll present the basic building blocks of the library and explain how they fit together.…

State of libp2p —
Gave a talk on the state of libp2p at FOSDEM 2022.
State of libp2p
Status quo and future roadmap of the peer-to-peer networking library libp2p.
libp2p is a universal, cross-platform, multi-language, modular peer-to-peer networking library powering multiple large-scale networks, for example IPFS, Ethereum 2, Filecoin or Polkadot.
We will discuss the current state of the project, eyeball the various language implementations, take a look at the many live networks running on top of libp2p today and finally cover the project roadmap for the years to come.…

35th DistSys Reading Group - Nym —
In our previous session we looked into Mixnets, more specifically Loopix. With this session we stayed in the space, talking about a network adopting many concepts from Loopix, namely Nym.
As a preparation, we read section 1 through 4 of the Nym whitepaper.
Introduction Network-level surveillance The Nym Network Design Mixnet for Network-Level Privacy Diaz, Claudia, Harry Halpin, and Aggelos Kiayias. “The Nym Network.” (2021).

34th DistSys Reading Group - Mixnets —
34th session was on Mixnets as lots of people suggested in the past. As a preparation we read the Loopix paper.
Piotrowska, Ania M., et al. “The loopix anonymity system.” 26th {USENIX} Security Symposium ({USENIX} Security 17). 2017.
https://www.usenix.org/system/files/conference/usenixsecurity17/sec17-piotrowska.pdf
The corresponding talk by Ania Piotrowska is very much worth watching as an additional resource.

33rd DistSys Reading Group - BGP 3 —
In our third BGP session we focused on BGP security, more specifically we discussed how to perform hijack and interception attacks using BGP. The primary paper of the session was:
Birge-Lee, Henry, et al. “Sico: Surgical interception attacks by manipulating bgp communities.” Proceedings of the 2019 ACM SIGSAC Conference on Computer and Communications Security. 2019.
A good introduction to RPKI can be found here.…

32nd DistSys Reading Group - BGP 2 —
After our first BGP session, introducing the protocol based on the convergence problem of BGP, our second session on BGP covered route propagation and tuning. The primary paper was:
Gray, Caitlin, et al. “BGP Beacons, Network Tomography, and Bayesian Computation to Locate Route Flap Damping.” Proceedings of the ACM Internet Measurement Conference. 2020.…

Optimizing Yamux Flow Control - Sending Window Update Frames Early —
Below is a summary of our efforts to optimize flow control in the Rust Yamux implementation. While not a novel approach, I still find the end result worth sharing thus my forum post.

31st DistSys Reading Group - BGP 1 —
We decided to turn our interest to BGP which we will devote 3 sessions to. In today’s session - the first one - we introduced BGP, looked at the convergence problem, as well as the solution suggested in the paper below.
Gao, Lixin, and Jennifer Rexford. “Stable Internet routing without global coordination.” IEEE/ACM Transactions on networking 9.6 (2001): 681-692.
To play around with BGP as well as general Internet routing:…
