Module zebra_state::service::finalized_state::disk_format::upgrade::cache_genesis_roots

Updating the genesis note commitment trees to cache their roots.

This reduces CPU usage when the genesis tree roots are used for transaction validation. Since mempool transactions are cheap to create, this is a potential remote denial of service.

Functions

• detailed_check
  Detailed check that all trees have cached roots.
• quick_check
  Quickly check that the genesis trees and sprout tip tree have cached roots.
• run
  Runs disk format upgrade for changing the sprout and history tree key types.
