Motivation

We want to run these anchor verifications on a CPU-bound thread pool.

Solution

  • Use a parallel iterator when checking sprout_anchors_refer_to_treestates(..) for a block if sprout_final_treestates is not empty.
  • Use in_place_scope_fifo for running sprout anchors checks on an UnminedTx if the transaction has sprout joinsplit_data

Review

Anyone can review.

Reviewer Checklist

  • Will the PR name make sense to users?
    • Does it need extra CHANGELOG info? (new features, breaking changes, large changes)
  • Are the PR labels correct?
  • Does the code do what the ticket and PR says?
  • How do you know it works? Does it have tests?

We try to only make performance-related changes where we have evidence of slow code or a denial of service risk.

Otherwise, we could spend a lot of time modifying code that's not performance critical, making it harder to maintain. And sometimes the setup costs exceed any performance gains.

This will need a rebase, anyone can re-approve once that's done.
