Move gen-hydra-key to hydra node

[v0d1ch]

Hydra-tools is now only holding a single command and when using Hydra, it feels a bit unnecessary to just download another docker image / binary to generate keys.

At the same time, hydra-node already has two sub-commands and we could move it there easily.

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.

3-nodes Scenario

A rather typical setup, with 3 nodes forming a Hydra head.

Number of nodes	3
Number of txs	900
Avg. Confirmation Time (ms)	108.084125700
P99	268.73059844ms
P95	226.56070464999993ms
P50	88.31115ms
Number of Invalid txs	0

Baseline Scenario

This scenario represents a minimal case and as such is a good baseline against which to assess the overhead introduced by more complex setups. There is a single hydra-node d with a single client submitting single input and single output transactions with a constant UTxO set of 1.

Number of nodes	1
Number of txs	300
