Struct ExecutionStage 

Source 
pub struct ExecutionStage<E>
where
    E: ConfigureEvm,
{ /* private fields */ }
Expand description

The execution stage executes all transactions and update history indexes.

Input tables:

  • [tables::CanonicalHeaders] get next block to execute.
  • [tables::Headers] get for revm environment variables.
  • [tables::HeaderTerminalDifficulties]
  • [tables::BlockBodyIndices] to get tx number
  • [tables::Transactions] to execute

For state access [LatestStateProviderRef] provides us latest state and history state For latest most recent state [LatestStateProviderRef] would need (Used for execution Stage):

  • [tables::PlainAccountState]
  • [tables::Bytecodes]
  • [tables::PlainStorageState]

Tables updated after state finishes execution:

  • [tables::PlainAccountState]
  • [tables::PlainStorageState]
  • [tables::Bytecodes]
  • [tables::AccountChangeSets]
  • [tables::StorageChangeSets]

For unwinds we are accessing:

  • [tables::BlockBodyIndices] get tx index to know what needs to be unwinded
  • [tables::AccountsHistory] to remove change set and apply old values to
  • [tables::PlainAccountState] [tables::StoragesHistory] to remove change set and apply old values to [tables::PlainStorageState]
