A formally defined model to describe and compare payment system architectures (BIS)

The Bank for International Settlements (BIS) proposed a formally defined model to represent three key functions of payment system architectures: issuance/withdrawal, holding and transfer of funds in a standardized manner. The model defines payment diagrams, using a precisely defined syntax. The paper illustrates the application of these diagrams for domestic and cross-border account transfers, as well as cash, card, e-money and stablecoin payments. However, the payment diagrams can be used for any type of funds and can be applied across different payment system architectures. It also demonstrates how the diagrams correspond to the balance sheet approach commonly used in economics, and that it offers added value by providing an end-to-end visualization of every stage of the payment journey. The model provides a tool for central banks, regulators and the payment industry to better understand and compare existing and new payment system architectures. [Read more at the BIS]

Fnality rolls out “earmarking” for programmable payments (Fnality)

Fnality has released a new “earmarking” feature that allows banks to program funds for release upon receipt of proof of an event elsewhere. For example, institutions will be able to systematically program when funds move in exchange for a specified asset, or a related market event. A proof is a cryptographically signed piece of data representing specific information from another system, triggering the release of the £FnPS’s digital representation of central bank funds. When an earmark is in place prior to its release, the funds remain on the originating participant’s balance sheet at all times. [Read more at Fnality]
