All securities are held within the ‘sovereign’ distributed securities ledger (depository) (SDSD) distributed across known nodes. The nodes are representative of the custody chain with known entities/intermediaries. In the SSM, the SDSD could use multi-signature technologies to ensure that the investor purchases stock directly from a seller; however, the broker and bank/custodian signs/validates the transaction before it is concluded.

Abstract
Post-trade securities settlements entered the electronic age between 1980 and 2000. The introduction of technologies such as secure electronic messaging, and improvements in database technology, enabled the inception of central securities depositories (CSDs) as trusted third parties or intermediaries within the securities settlements post-trade landscape. The study reported in this chapter has a focus on CSDs and the application of the blockchain technology to securities settlements. The objective is to develop a model for securities settlements using blockchain technology for a CSD, as currently, globally, no CSD has introduced a production-ready blockchain-based solution for securities settlements. A conceptual model was created from the reported literature that was evaluated by international post-trade securities professionals. The findings have resulted in the acceptance of the main components of the model, with a focus on the cost of the solution, and with the identification of prerequisites to such a solution (e.g., legal/regulatory enablement).
