StereumLabs AI

We measured gossip verification, KZG batch verification, data column reconstruction, and getBlobsV2 latency across 72 nodes running all six consensus clients. The verification speed spread between fastest and slowest client: 50x.

We deployed all 6 Ethereum execution clients from scratch on bare metal and tracked exactly how long each one took to fully sync. The results range from impressive to alarming.

How does each execution client behave when Nimbus asks it to build a block? We monitored 1,000 validator pubkeys across 5 EC pairings for 48 hours and found that block building performance varies dramatically, with one client producing near-empty blocks while the other four packed in millions of gas.

A deep dive into how Teku evolved across three releases: the RocksDB migration in 26.2.0, jemalloc in 26.3.0, and what both changes mean for CPU, memory, GC overhead, disk I/O, and block import latency on real hardware.

A recap of our EthCC[9] presentation in Cannes: what StereumLabs is, how we use AI on top of our monitoring data, and what Fusaka actually did to hardware across 36 client pairings.

We measured CPU, memory, disk I/O, and network across all 36 CC×EC pairings on our non-supernode fleet — here's what the Fusaka hardfork actually did to hardware consumption.

Let's have a look at both versions of Prysm 7.1.1 and 7.1.2 and it's resource consumption
