The report explores the shift in focus from theory to practice, examining 7 real-world applications of blockchain, such as enhancing trust in the Sharing Economy, building a distributed smart grid, lowering the cost of title insurance, and changing the face of finance across capital markets, trading and control.
Essentially, by enforcing agreement at the time of entry, blockchain could eliminate some of the most common post-trade issues and errors, such as incorrect settlement instructions or incorrect account/order details. Today, these details are confirmed/affirmed by multiple parties (DTCC, custodians, broker/dealer, clients) and multiple times throughout the life cycle of the trade. If blockchain could be fully implemented across these parties, many of these attributes could be included in a smart contract, thus becoming a pre-trade requirement to execute an order rather than a downstream, post-trade check that requires multiple parties to agree.
