	// using either `Local` or `External` should most likely just allow `InBlock`
	// transactions as well.
	TxnInBlock TransactionSource = iota

	// TxnLocal indicates transaction is coming from a local source.
	//
	// This means that the transaction was produced internally by the node
	// (for instance an Off-Chain Worker, or an Off-Chain Call), as opposed
	// to being received over the network.
	TxnLocal

	// TxnExternal indicates transaction has been received externally.
