	// Note: This is a blocking call
	// the next height is the existing finalized and executed block's height + 1.
	// If a block at next height becomes finalized and executed, then:
	// 1. write the registers to write ahead logs
	// 2. save the registers of the block to OnDiskRegisterStore
	// 3. prune the height in InMemoryRegisterStore
	// any error returned are exception
	OnBlockFinalized() error

	// LastFinalizedAndExecutedHeight returns the height of the last finalized and executed block,
	// which has been saved in OnDiskRegisterStore

	// If a block is not executed, it does not distinguish whether the block exists or not.
	// It returns:
	// - (true, nil) if the block is executed, regardless of whether the registers of the block is pruned on disk or not
	// - (false, nil) if the block is not executed
	// - (false, exception) if running into any exception
	IsBlockExecuted(height uint64, blockID flow.Identifier) (bool, error)
}

type ScriptExecutor added in v0.32.0 

type ScriptExecutor interface {

	// ExecuteScriptAtBlockID executes a script at the given Block id
	// it returns the value, the computation used and the error (if any)

	// GetAccount returns the Account details at the given Block id
	GetAccount(ctx context.Context, address flow.Address, blockID flow.Identifier) (*flow.Account, error)
