As of September 24 on
crypto market, Bitcoin is trading at around $84,100, Ethereum at $2,680, and XRP at $1.50, while stablecoin policies, Bitcoin’s quantum security, and tokenization oversight in Europe stand out among the day’s key developments. The U.S. administration is reportedly considering an initiative to expand the international use of dollar-backed stablecoins, while the estimated computational cost of experimental quantum-resistant Bitcoin transactions has declined significantly. The European Securities and Markets Authority (ESMA), meanwhile, has identified artificial intelligence and tokenization as the first focus areas of its new digital innovation supervisory priority.
From a Market Perspective: Stablecoin Policy, Bitcoin Security, and Tokenization
Today’s three developments highlight changes taking place across different areas of the crypto ecosystem, including money transfers, blockchain security, and integration with traditional financial markets.
The stablecoin initiative being considered in the U.S. brings the relationship between dollar-backed digital assets, cross-border payments, and the international use of the U.S. dollar into focus. Developments around Bitcoin’s quantum security, meanwhile, are focused on how existing blockchain infrastructure could be improved against technological risks that may emerge in the future.
ESMA’s new supervisory priority also shows that regulators’ approach to these technologies is evolving as tokenization and artificial intelligence become more widely used in the products and processes of financial institutions. While daily
cryptocurrency prices reflect short-term market movements, developments like these are also important for understanding the broader technological and regulatory transformation of the ecosystem.
U.S. Considers Expanding Global Use of Dollar-Backed Stablecoins
The U.S. administration is reportedly considering a new initiative aimed at increasing the use of dollar-backed
stablecoins overseas. According to Bloomberg, citing people familiar with the matter, the plan is still under consideration and could also include partnerships with private-sector companies.
Several federal agencies, including the U.S. Treasury Department, the State Department, and the U.S. International Development Finance Corporation (DFC), could reportedly play a role in the potential initiative. One of the objectives would be to expand the international use of dollar-denominated stablecoins while supporting the role of the U.S. dollar in the global financial system.
Stablecoin issuers generally hold cash and short-term U.S. government securities in the reserves backing their dollar-denominated assets. As a result, a connection is also being drawn between the growth of stablecoin usage and demand for U.S. Treasury securities. The initiative under consideration could support such demand, according to the report.
The regulatory framework for payment stablecoins in the U.S. has also continued to take shape in recent months. The
GENIUS Act established a federal regulatory framework for payment stablecoins, while the U.S. The Treasury Department began seeking public feedback in August on new rules related to the implementation of the law.
However, it is important to note that the international stablecoin initiative in question has not yet been finalized or implemented as an official program. The information currently available is based on Bloomberg’s report, which cited sources saying the U.S. administration is considering such a model.
Estimated Cost of Quantum-Resistant Bitcoin Transactions Declines
The computational cost of the experimental Quantum-Safe Bitcoin (QSB) approach, developed to help protect
Bitcoin against potential future security risks posed by quantum computers, has reportedly declined.
According to StarkWare, optimizations made as part of the Quantum-Safe Bitcoin Optimization Challenge reduced the estimated GPU computing cost required to prepare a quantum-resistant Bitcoin transaction from approximately $320 to below $67. This represents a reduction of around 79%.
The initial cost of around $320 was based on the first QSB transaction conducted on the Bitcoin mainnet on August 26. Preparing the transaction required approximately 3,100 GPU-hours of computation across around 100 GPUs. The computational cost was reported to be approximately $320, excluding Bitcoin network transaction fees.
The optimization challenge, launched on September 16, brought together developers, researchers, and artificial intelligence tools to make the computations used to generate QSB transactions more efficient. StarkWare said that 62 improvements across two core computational tasks were accepted during the first week, with benchmark results showing a cost reduction of around 79%.
An important distinction is that the newly announced level below $67 does not represent the actual cost of a second Bitcoin mainnet transaction. The latest optimizations have so far only been demonstrated in benchmark tests. Therefore, while the development indicates progress in the computational efficiency of quantum-resistant Bitcoin transactions, the new cost has not yet been confirmed through another on-chain transaction.
The QSB design is an experimental approach that aims to provide hash-based protection without changing Bitcoin’s existing consensus rules. StarkWare continues to view protocol-level changes as the long-term solution for providing broader quantum protection for Bitcoin.
ESMA Makes AI and Tokenization a Supervisory Priority
The European Securities and Markets Authority (ESMA) has announced that it will launch a new Union Strategic Supervisory Priority (USSP) focused on digital innovation from 2027. Artificial intelligence and tokenization will be the first focus areas of the new program.
According to ESMA, the objective of the program is to ensure that supervisory authorities across the European Union have the knowledge and capacity required to assess the use of emerging technologies. Together with national competent authorities, ESMA will examine how supervised entities use artificial intelligence and tokenization technologies in particular.
Tokenization involves representing traditional financial assets or rights associated with them as digital tokens on distributed ledger technologies such as
blockchain. As their use in the financial sector expands, the interaction of these systems with investor protection, market infrastructure, and operational processes is increasingly becoming part of regulators’ agendas.
ESMA’s new digital innovation priority will continue alongside supervisory work focused on cybersecurity and operational resilience that has been in place since 2025. The authority also notes that its supervisory focus may be updated in response to future technological developments, including advanced artificial intelligence models.
USSP programs are among the tools used to align national supervisory practices across areas considered strategically important for investor protection, financial stability, and the orderly functioning of markets throughout the European Union.
CoinTR Insight
Today’s developments show that the role of stablecoins in the international financial system, Bitcoin’s long-term technical security, and the use of tokenization in traditional financial markets are simultaneously becoming subjects of different regulatory and technological initiatives.
The initiative being considered in the U.S. particularly highlights the cross-border use of dollar-backed stablecoins, while ESMA’s announcement shows that tokenization in Europe is increasingly being evaluated not only within experimental projects but also as a direct focus of supervisory processes.

On the Bitcoin side, research into quantum security is aimed at preparing for technological risks that could emerge in the future rather than responding to an existing attack. Although the reduction in QSB costs indicates technical progress in this field of research, work on how broader quantum resistance could be implemented for Bitcoin is still ongoing.
Forward-Looking Assessment
-
U.S. stablecoin initiative: It will be important to monitor whether the plan under consideration develops into an official program and what roles the Treasury Department, State Department, and DFC may play. The scope of potential partnerships with the private sector also remains unclear.
-
Bitcoin’s quantum security: It will be important to monitor whether computational costs can be reduced further during the QSB optimization challenge and whether the benchmark results are confirmed through a new mainnet transaction. Work within the Bitcoin community on protocol-level quantum protection is also continuing as a separate area.
-
ESMA’s new supervisory period: With the implementation of the digital innovation priority in 2027, attention will turn to how national regulators across Europe develop common supervisory approaches toward financial institutions using artificial intelligence and tokenization.
