The minting policy hash is only usable for comparison. As the script is parameterized, the actual script is unique per head.

`FanOut` transaction costs

Involves spending head output and burning head tokens. Uses ada-only UTxO for better comparability.

End-to-end benchmark results

This page is intended to collect the latest end-to-end benchmark results produced by Hydra's continuous integration (CI) system from the latest master code.

Please note that these results are approximate as they are currently produced from limited cloud VMs and not controlled hardware. Rather than focusing on the absolute results, the emphasis should be on relative results, such as how the timings for a scenario evolve as the code changes.
