Numerous big firms are testing blockchain-inspired systems that promise to make digital transactions more secure and efficient, while a handful, such as Visa and HSBC, have launched their own commercial platforms.

Proponents say it creates an irrefutable digital paper trail that is more transparent and cuts out room for manipulation. This could facilitate more secure transactional records for the transfer of almost any kind of asset, from cash and shares to property and insurance contracts.
