Meeting Time: Wednesday, July 01, 2026 at 15:30 UTC (60 minutes)
The meeting focused on updates and discussions regarding network improvements, particularly around partial columns, GET BLOBs changes, and sparse block pool implementations. Daniel reported seeing improvements in node bandwidth and latency after shipping partial column support, with nodes in Australia showing more benefits than European nodes. The team discussed plans to test GLOAS and partial column changes on DevNet 6, with Aarsh noting that the Funu partial column changes were merged to the release branch and would be released the following week. Bosul mentioned investigating sparse block pool implementation and testing challenges, while Kamil suggested running shadow tests using ethshadow to simulate approximately 500 nodes. Anton briefly mentioned that QUIC fixes were being worked on and likely already in production.
The transcript appears to be a fragmented and unclear conversation in Russian with some mixed languages. The participants, including Kamil, Daniel, Justin, and Anton, exchanged brief greetings and some unclear statements, but no coherent discussion, decisions, or action items emerged from the conversation. The content was too disjointed to extract meaningful summary information.
Daniel reported on the deployment of partial column shipping, which is enabled by default on Hudi and Sepolia networks. He noted that approximately 2.5 out of 6 mesh nodes had rolled out RODs, resulting in improved network performance with a drop in total bandwidth from 2.5 to 2 mebibytes per second and a latency reduction from 1.3 to 1.15 seconds on average. Daniel also mentioned that vulnerability fixes were included in the recent release.
The team discussed improvements to DA wait time and blob traffic, with Daniel noting that nodes in Australia benefited more from the improvements than European nodes. They agreed to deploy both HasBlobs and GetBlobs v3 changes to BlobDevNet0, and planned to test GLOAS partial column changes on DevNet 6. Aarsh mentioned that the Funu partial column changes were ready for release next week, while GLOAS partial column changes would be reviewed internally the following week. The team also discussed GetBlobs v4 implementation plans, with Daniel indicating that a draft PR was ready for testing on Lighthouse.
The team discussed testing sparse block pool functionality, with Bosul reporting that while the feature is merged on DevNet 6, it requires further investigation due to some bugs. Kamil mentioned that both Prism and Geth now support sparse block pools, and he proposed running shadow tests using ethshadow to simulate approximately 500 nodes, which would take about 10 minutes of simulated time. The team agreed to use DevNet 0 for testing once clients are ready, with Bosul suggesting it could be launched quickly when the necessary clients are integrated.
Anton reported that the team is working on QUIC with several fix releases already in production. Kamil confirmed there were no other agenda items to discuss and the conversation ended.
