The Monetary Authority of Singapore (MAS) announced that it has completed its first cross-border payment with The Bank of Canada (BoC) using the distributed ledger technology blockchain.
In what it refers to as 'Project Jasper-Ubin', the project saw MAS and BoC linking up their respective blockchain projects, Jasper and Ubin, which are built on two different blockchain networks: R3’s Corda and JPMorgan’s Quorum, respectively.
The two networks were connected using a technique called 'Hashed Time-Locked Contracts' (HTLC) to ensure all payments happen at the right time and in the correct order.
Successfully doing so, the two banks claimed to be capable of doing international direct Payment versus Payment (PvP) much quicker than conventional systems which require middlemen to verify the transactions.
Lending tech support for the project were Accenture and JPMorgan, which assisted development of the Canadian project on Corda and the Singapore project on Quorum, respectively.

According to MAS on its website reporting Project Jasper-Ubin:
According to Scott Hendry, Bank of Canada’s senior special director for financial technology:
According to David Treat, Accenture’s managing director and global blockchain lead:

The project started when MAS announced that it was partnering with R3, a DLT company back on November 2016, as part of efforts to increase the efficiency of banking payments, and also with a consortium of financial institutions on a proof-of-concept project to conduct inter-bank payments using blockchain technology.
On the MAS and BoC joint report describing the different design options to enable such settlement systems, they stated that:
At this time, the Jasper-Ubin project is experimental in nature.
Sopnendu Mohanty, chief fintech officer at MAS said that:
"The next wave of central bank blockchain projects can make further progress by bringing technology exploration together with policy questions about the future of cross-border payments. It is challenging work, and we welcome other central banks to join us in this global collaboration, to bring benefit to consumers, businesses and the broader financial industry."
