Under the proposed system of Segregated Witness, an extended block must be created alongside the main block. This extended block would contain the signature data of the transaction. The system proposes that the main block is divided into two, one with just the signature data, and the other with just the record of the occurrence of the transaction.
Austrian economics looks at the economy at the micro level and is more interested in what generates wealth. Savings and good investments are what ultimately lead to prosperity in this theory and so, not all transactions are good. Bad investments and over-consumption cause down cycles so those are to be avoided.
