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

End-To-End Benchmark Results

This page is intended to collect the latest end-to-end benchmarks results produced by Hydra's Continuous Integration system from the latest master code.

Please take those results with a grain of salt as they are currently produced from very limited cloud VMs and not controlled hardware. Instead of focusing on the absolute results, the emphasis should be on relative results, eg. how the timings for a scenario evolve as the code changes.

Only minor comments, on to the next action in the model!

[ch1bo]

Could: just keep this function here.

[ch1bo]

This will make the model runner spam / poll the node quite a lot. Do we need this change?

[v0d1ch]

No, this is a leftover
