Flaky blob transaction test #125

Hi,

We're seeing a bit of flakiness running a devnet with assertoor's blob-transactions-test. The test fails intermittently.

It looks like it's checking each slot for blobs but no blobs are getting included. I noticed some relevant logs suggesting there may be an issue with blob tx genreation:

time="2025-10-29T02:20:24Z" level=error msg="error generating transaction: nonce too high: tx nonce 3, gapped nonce 1" RunID=4 TestID=blob-transactions-test module=test task=generate_blob_transactions taskidx=21

The config we use is pretty straight forward (ignore the additional_services as they are set to an empty list in our CI tests)
https://github.com/sigp/lighthouse/blob/f6859b1137de5b36501b1249497bebbf5ba4a805/scripts/local_testnet/network_params.yaml

Failing job example (full log available as job artifacts)

Is there anything we can do to improve the reliability of this test?
