Future-proofing the operations has been a long hard quest for the banking institutions around the globe, and eve more so since the emergence of the cryptocurrencies. And now the next step forward has been made by Bank of England. As part of their proof-of-concept network for real-time gross settlement they are trialing the use of distributed ledger technology (DLT).
Back in 2017 Bank of England has first revealed that they were working on using DLT for near-instant transaction system. Though, at that tie they were adamant, that such a technology can't be the sole driving force for such application. Now, they are backtracking a bit, stating that while nowadays DLT is not yet sufficiently mature, they will endeavor to develop it for the time when it gains a more widespread adoption.
The trial run is to see how distributed ledger-based system performs for the real-time gross settlement service, and if it performs well enough to be used on the permanent basis.
In broader sense, such a move can represent a more amiable stance toward blockchain as a whole for the UK central bank in the near future.
