## Why this should be merged EVM parallel co-processors that interface with the regular transaction path via precompiles. ## How this works Introduces the `parallel.Processor`, which orchestrates a set of `parallel.Handler`s. Each `Handler` performs arbitrary, strongly typed processing of any sub-set of transactions in a block and makes its results available to a precompile and/or a post-block method for persisting state. Although stateful, `Handler`s can only read the pre-block and post-block state, which isolates them from conflicts with the regular transaction path. There is deliberately no support for a precompile to "write" to a `Handler`, only to "read". This is because the transaction might still revert, which would also have to be communicated to the `Handler`, resulting in unnecessary complexity. Logs/events are the recommended approach for precompile -> `Handler` communication, to be read from the `types.Receipts` at the end of the block. ## How this was tested Integration tests covering: 1. Selection of transactions to process + end-to-end plumbing of data through a `Handler`. 2. Registration as a precompile, exercised with actual transaction processing, and demonstrating log + return-data correctness. --------- Signed-off-by: Arran Schlosberg <519948+ARR4N@users.noreply.github.com> |
