Documentation for tests/cancun/eip4844_blobs/test_excess_blob_gas.py::test_correct_decreasing_blob_gas_costs@verkle@v0.0.6.

Generate fixtures for these test cases for Cancun with:

Cancun only:

fill -v tests/cancun/eip4844_blobs/test_excess_blob_gas.py::test_correct_decreasing_blob_gas_costs --fork=Cancun --evm-bin=/path/to/evm-tool-dev-version

For all forks up to and including Cancun:

fill -v tests/cancun/eip4844_blobs/test_excess_blob_gas.py::test_correct_decreasing_blob_gas_costs --until=Cancun

Test calculation of the excessBlobGas and blob gas tx costs at value points where the cost decreases to interesting amounts.
