The standard use of Raft is for implementing a fault tolerant, replicated state machine by means of a replicated log, maintained at each server within a replication group. Depending on the nature of the state we want to replicate, we can employ a simpler variant of Raft that achieves the same essential correctness properties. We can call this logless Raft and it can be useful when we are only replicating a single, small piece of state (e.g. configuration, metadata, etc.) between servers.| William Schultz
David Schleicher has a proposal for how Congress can speed up infrastructure construction and reduce costs for megaprojects. Writing about what further research needs to be done, he distinguishes reasons from explanations. I have argued that many of the stories we tell about infrastructure costs involve explanations but not reasons. There are plenty of explanations […]| Pedestrian Observations

Digital asset transfer systems are at a crossroads. An idea that first captured attention between 2020 and 2022—Byzantine Consistent Broadcast (BCB)—is now experiencing a revival with projects like Pod and Delta. In this post, we to show that while BCB can unlock incredible performance through parallel state execution, it also introduces important challenges, especially around expressivity and the scalability of reads. The goal is to explain why this approach is both exciting and demanding.| François Garillot
We have been doing a Zoom distributed systems paper reading group for 5 years and have covered around 190 papers. This semester, we should reach the milestone of 200 papers. Over the years, my commitment to the group has varied — at some point, I was writing paper reviews, and more recently, I’ve had less […]| Aleksey Charapko

Let’s cut to the chase: you’re probably wondering if Humanode’s Proof of Biometric Uniqueness is really as solid as we describe it. You’ve heard the pitch – biometrics over capital, privacy over profit— in our previous article Decentralization Through Biometric Uniqueness: One Person, One Node in Humanode.| Humanode
Let’s be real for a second. When you think about consensus (Sybil-resistance) mechanisms in blockchain, what’s the first thing that pops into your head? Mining power? Stake size? Probably. And if we’re honest, it’s easy to feel a little uncomfortable with that. Like, deep down, you| Humanode
Ever binge-watched a series where things go fine, and you don’t see a twist coming, and then out of the blue, there’s a twist that leaves you in a shock? You just can’t tear yourself away, right? The same thing can occur with a blockchain only that| Humanode

It turns out that carving things into stone is a pretty good way to preserve the canonical truth. But first you have to agree on the truth, which isn't so straightforward. (Photo by Luca Santos on Unsplash)| Etherean.org
