Transaction replay testing tool

[ilblackdragon]

Tool, that allows to:

• Read out chain history
• Recreate transactions, where all keys are replaced with new keys this tool created.
• Replay all of these transaction on the initial state.
• Validate that state outside of keys matches.
• Validate that performance is within expected bounds

Additional considerations, that transactions relaying on randomness output or transaction hash, hence this can only be done within runtime-standalone where a context can be provided.

Performance changes of runtime can be tracked using this tool.

PS. Ethereum transaction replay can be cool as well, but may be even harder to orchestrate as there will be context.

Do you want to have a tool that will re-submit all the transactions to a regularly running network or use runtime-standalone and only check the state?

FYI, some preliminary infrastructure of runtime-standalone is getting closer: https://github.com/nearprotocol/nearcore/blob/97ac8315e275f594090cc8fd6698a17b29707fe3/runtime/runtime-standalone/src/lib.rs#L261-L314

We can do both, and start with runtime-standalone as it is going to be easier. Having both will allow us to immediately find whether the source of regression is in the runtime or inside the chain, e.g. p2p network.
