Fix tutorial download instructions

[ch1bo]

• Fixes the tutorial download instructions for linux and macos as the paths in the cardano-node tarball had changed in 8.9.0.

• Also, the macos instructions were referring the hydra-local build of mithril and cardano-node which we had temporarily.

• Also update to latest version of mithril and use the latest snapshot as this is now available in mithril-client

Transactions Costs

Sizes and execution budgets for Hydra protocol transactions. Note that unlisted parameters are currently using arbitrary values and results are not fully deterministic and comparable to previous runs.

• 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.
