Independent Ethereum client measurements
Neutral, hardware-backed measurements of Ethereum execution and consensus clients.

From the blog
A few hand-picked posts from our blog.
The same six Ethereum consensus clients on identical hardware reported between 0 and 5,791 reorgs over 90 days. Why their counters disagree, and what it means for your alerts.
Caplin v3.3.10 collapses EL and CL into one Erigon binary. We compared it head-to-head against six classic Erigon+CC pairings across 50,000 blocks.
Every EC connects to different peers, churns at different rates, and sees a different slice of the network. From 25 to 130 peers, with one common cloud misconfig that quietly degrades 70% of connections.

Neutral, hardware-backed measurements with full methodology disclosure. Cite our datasets, reproduce our runs.
See how your EC or CC behaves across 36 pairings, multiple versions, and real workloads.
How we measure
We publish our scenarios, flags, hardware specs, and limitations so others can reproduce or critique our results.
Read the full methodology →Equalized conditions, documented config policy, no vendor allegiance. Every client gets the same scenario and the same resource budget.
Anchored on declared bare-metal in Vienna (Epyc 9654P, ZFS raidz1, dedicated NICs). Cloud profiles are disclosed and pinned.
Every run publishes versions, flags, environment hashes, and sampling metadata. You can rerun what we ran or critique what we measured.
