• Abstract: Central banks are actively exploring central bank digital currencies (CBDCs) by conducting research, proofs of concept and pilots. However, adoption of a CBDC can risk fragmenting both payments markets and retail deposits. In this paper, we aim to provide a mitigation to this fragmentation risk by presenting an illustrative industry architecture which places CBDCs and commercial bank money on a similar footing. We introduce the concept of ecosystems providing a common programmability layer that interfaces with the account systems at both commercial banks and the central bank. We focus on a potential United Kingdom (UK) CBDC, including industry ecosystems interfacing with commercial banks using Open Banking application programming interfaces (APIs).

• Payments Use Cases and Design Options for Interoperability and Funds Locking across Digital Pounds and Commercial Bank Money [0.0]
  We focus on three key capabilities: communication between digital pound ecosystem participants, funds locking, and interoperability across digital pounds and commercial bank money. We conclude that a financial market infrastructure (FMI) providing specific capabilities could simplify the experience of ecosystem participants, simplify the operating platforms for both the Bank of England and digital pound Payment Interface Providers (PIPs) and facilitate the creation of innovative services.

  Task-oriented dialogue (TOD) systems are mainly based on the slot-filling-based TOD (SF-TOD) framework. We argue that the current TOD benchmarks are limited to surrogate real-world scenarios and that the current TOD models are still a long way to cover the scenarios. In WebTOD, the dialogue system learns how to understand the web/mobile interface that the human agent interacts with, powered by a large-scale language model.
