The Economics of Distributed Ledger Technology for Securities Settlement

Evangelos Benos, Rodney Garratt, Pedro Gurrola-Perez
2019 Ledger  
Our main conclusions are that: i) Although DLT has the potential to significantly reduce costs in securities settlement, implementation is challenging, ii) technological innovation in the post-trade industry  ...  We apply economic principles to understand how distributed ledger technology (DLT) might impact the innovation process and eventual market structure in the security settlement industry.  ...  As such, there are stronger incentives for technological innovations that either generate new revenue or reduce costs. An area with great potential for cost reductions is post-trade processing.  ...

Netcoin: A Traceable P2P Electronic Cash System

Hitesh Tewari, Eamonn O. Nuallain
2015 2015 IEEE International Conference on Web Services  
Its salient features are that it is a traceable system with an efficient mechanism for verifying transactions. Netcoins are reusable and can be easily passed from one user to another.  ...  There is no need to maintain a public ledger, which would inhibit use on a global scale because of rapidly increasing memory and bandwidth requirements.  ...  Other examples may be search engines that want to reduce transaction costs for clients who advertise for them etc.  ...
