As directed by the President of the United States, Joe Biden, the Office of Science and Technology Policy (OSTP) submitted a report analyzing the design choices for 18 រូបិយប័ណ្ណឌីជីថលរបស់ធនាគារកណ្តាល (CBDC) systems for possible implementation in the US.
បច្ចេកទេស ការវិភាគ of the 18 CBDC design choices was made across six broad categories — participants, governance, security, transactions, data and adjustments. The OSTP foresees technical complexities and practical limitations when trying to build a permissionless system governed by a central bank, adding:
"វាអាចទៅរួចដែលថាបច្ចេកវិជ្ជាដែលគាំទ្រវិធីសាស្រ្តគ្មានការអនុញ្ញាតនឹងមានភាពប្រសើរឡើងគួរឱ្យកត់សម្គាល់តាមពេលវេលា ដែលអាចធ្វើឱ្យវាកាន់តែសមស្របក្នុងការប្រើនៅក្នុងប្រព័ន្ធ CBDC" ។
However, the analysis assumed there is a central authority and a permissioned CBDC system.
Helping policymakers decide on the ideal US CBDC system, the OSTP report highlighted the implications of including third parties in the two design choices under the ‘participants’ category — transport layer and interoperability. For governance, the report weighed various factors related to permissioning, access tiering, identity privacy and remediation.
Other important factors OSTP wants policymakers to consider include cryptography and secure hardware (for security), signatures, transaction privacy, offline transactions and transaction programmability (for transactions), data model and ledger history (for data) and fungibility, holding limits and adjustments on transactions and balances (for transactions).
The technical evaluation for a US CBDC system highlighted the report’s inclination toward an off-ledger, hardware-protected system. Upon the launch of a US CBDC, the report will eventually highlight the various trade-offs policymakers decided to make when finalizing the design choices.

On Sept. 8, the OSTP recommended monitoring and regulation while weighing the environmental and energy impact of crypto assets នៅសហរដ្ឋអាមេរិក។
The related OSTP report highlighted that crypto assets use approximately 50 billion kilowatt-hours of energy per year in the U.S., which is 38% of the global total, while adding:
"ការកត់សម្គាល់ការប្រៀបធៀបដោយផ្ទាល់គឺមានភាពស្មុគស្មាញ Visa, MasterCard និង American Express រួមបញ្ចូលគ្នា [... ] ប្រើប្រាស់តិចជាង 1% នៃអគ្គិសនីដែល Bitcoin និង Ethereum បានប្រើប្រាស់ក្នុងឆ្នាំដដែលនោះ បើទោះបីជាដំណើរការជាច្រើនដងនៃចំនួនប្រតិបត្តិការនៅលើខ្សែសង្វាក់ និងគាំទ្រឱ្យកាន់តែទូលំទូលាយរបស់ពួកគេក៏ដោយ។ ប្រតិបត្តិការសាជីវកម្ម។”
The report further noted the high energy consumption of ភស្តុតាងនៃការងារ (PoW) staking in crypto assets.
