Fusaka Devnet Updates
-
Devnet-3 update (https://dora.fusaka-devnet-3.ethpandaops.io/).
- Regained finalization, but lagging as of 2025-09-15 11:00 UTC.
- ethpandaops will investigate this "unplanned" non-finalization ))
-
Devnet-5 launched on Wed 2025-09-10 14:00 UTC.
- @felix314159 verified correct EL client configurations pre-launch via
eth_configusing a new execution-spec-tests command, more info: - Current overview by @barnabasbusa
- 3 BPOs so far (https://dora.fusaka-devnet-5.ethpandaops.io/).
- Next BPO scheduled for Tues 2025-09-16 06:32 UTC
- PSA:
tysmethpandaops diagnostic nodes: Modified Prysm nodes with some additional monitoring. - PSA: watchtower is not ran for devnet-5: If you need your client image to be updated, reach out to one of the pandas (from #interop).
- @tersec reported nimbus-Nethermind issues. These are on the Nethermind side as confirmed by @flcl42: These involve a complex reorg condition, a fix is WIP.
- Teku non-critical Prometheus exception, a fix is WIP.
- Teku-reth block building issue resolved (reth regression that was almost immediately resolved).
- @tersec brought up a kzg-issue that Nimbus is debugging with Prysm #interop message link, still a WIP.
- @tersec shared that Nimbus can't currently run consensus-specs release alpha.6 with kzg libraries 2.1.2 (but passes with kzg 2.1.1). @tbenr confirmed the same behavior when testing Teku and these KZG library versions. It's suspected that a client can't in general pass the alpha.6 tests fully without a column ID ordering which 2.1.2 (but not 2.1.1) enforce. @jtraglia will check the issue and create a new release.
- @felix314159 verified correct EL client configurations pre-launch via
No Shadow fork testing update.
eth_calls and EIP-7825 TX Limit Cap Interaction
- @pk910 brought up the implications of ~16.78mio tx gas limit cap from EIP-7825 following-up from a discussion with @holgerd77 in #execution-devs.
- @pk910 tested
eth_callwith "unlimited" gas and found issues with geth, erigon and reth #execution-dev message link.
New Hive Simulator for EIP-7934
New Hive Simulator eest/consume-sync (live since Wed 2025-09-10) @fselmo
- Introduced to test EL synchronization capabilities, in particular for EIP-7934 RLP Execution Block Size Limit.
- Overview in docs: https://eest.ethereum.org/main/running_tests/running/#sync
EL Consensus Test Overview
Fusaka EL Hive results overview by @spencer-tb
- Fusaka Dashboard now contains all EEST and ethereum/tests state tests filled for
PragueToOsaka,Osakaand allOsakaToBPO*transition forks, ~20,000 tests. - Results are good: Mainly non-critical (e.g., exception message matching). Remaining failures should be resolved over the course of next week.
- Subsequently: Focus on results for other forks on the "Generic" dashboard.
Gas limit testing update
STEEL/EEST:
- A new benchmark test wrapper format ongoing (abstracts out the EIP-7825 tx gas limit for better test dev-ex) :
- Verifying a bloatnet testing approach via
executeis ongoing.
Prototyping:
- XEN gas benchmark tests with mainnet state WIP ethereum/execution-spec-test#2101 @jochem-brouwer.
