, efficient, and instrumental in creating an honest network. This, in turn, limits risks to market integrity. The concept of open competition forms an important element of the BFA; therefore, consensus mechanisms should seek to be collaborative, egalitarian, interoperable, and inclusive. Consensus mechanisms must not favor certain members over others; DLT networks should be open to as many participants as possible while ensuring these participants are “known,” to protect financial integrity (through customer due diligence). Such consensus mechanisms should not create

Distributed Ledger Technology DLT, often confused or associated with “blockchain,” is essentially a database (see Box 2 ). 5 In general terms, a DLT network is a means used to maintain and share digital records instantaneously across a network of participants through nodes. Regardless of whether the network is intended to serve an existing platform or network or is
international monetary system are discussed. The note aims to provide a balanced view with considerations for practical implementation and probable long-term applications and benefits for payment system developments. Distributed Ledger Technology DLT enables entities to carry out transactions in payment and settlement systems without necessarily relying on a central authority to maintain a single ledger. 2 DLT networks could be open or closed (per-missioned) depending on their participation policies. Various DLT protocols have been used so far in experiments in
, cryptocurrencies are tokens that do not provide any right to the holder, but users may agree to exchange goods or services against them on a voluntary basis and may be necessary for the DLT network to operate, as they are used as an “internal unit of value” that compensates users for their contributions. On cryptocurrencies, see He and others 2016 and Adrian and Mancini Griffoli 2019 . On the broader category of crypto assets, see Cuervo and others 2019 .

technologies (DLTs). This paper examines the implications for energy consumption from different forms of crypto assets based on their distinct design elements. It investigates how the takeaways from this evaluation can inform the design of environmentally friendly central bank digital currencies (CBDCs). The energy consumption of crypto assets can vary greatly depending on two design elements of the supporting DLT network . The first element is the consensus mechanism used to achieve agreement about the present state of the network. Resulting energy needs range from very

A second FATF review is ongoing at the time of publication. 19 ”Token” is a very general term and relates to a representation of anything (tangible or intangible, of economic value or not, a stake, a voting or access right, etc.) in a particular ecosystem. Tokens can be explained as lines of code embedded in DLT networks that may serve
substitution of savings into more stable foreign currencies. 5. The adoption of digital money will be further buoyed by rapid changes in technology and infrastructure, services and service providers, consumer preferences, and the congruence of these trends. 6. The underlying technology and infrastructure are advancing rapidly . Distributed ledger technologies (DLTs) are becoming faster, more secure, more energy efficient, and increasingly scalable—they should soon be able to process large amounts of transactions seamlessly. Furthermore, DLT networks are becoming
