Want to know what happened in crypto today? Here are the latest developments affecting Bitcoin, blockchain, DeFi, Web3, stablecoins and crypto regulation.
Today’s biggest crypto stories include a new UK push to support stablecoin innovation, a quantum-resistant Bitcoin transaction tested on mainnet, and fresh progress on the US Securities and Exchange Commission’s planned crypto custody rules.
Bank of England Could Receive New Stablecoin Innovation Mandate
The UK government is moving to give the Bank of England (BoE) a broader role in supporting innovation around digital payments and stablecoins.
HM Treasury announced plans to introduce a secondary objective for the central bank focused on encouraging innovation in payment systems and new forms of digital money.
The proposed mandate would cover payment infrastructure using digital settlement assets, including stablecoins. However, maintaining financial stability would remain the Bank of England’s primary responsibility.
The move comes as the UK continues expanding its digital asset strategy. Regulators are working on new stablecoin rules, testing modern payment systems and strengthening cooperation with the United States on digital finance.
If implemented, the new mandate could give the Bank of England a more active role in shaping how stablecoins are integrated into the UK financial system.
StarkWare Tests Quantum-Resistant Bitcoin Transaction
StarkWare has also announced an experimental quantum-resistant Bitcoin transaction completed directly on the Bitcoin mainnet.
Researcher Avihu Levy carried out the test using a system known as Quantum Safe Bitcoin (QSB).
According to StarkWare, the transaction was confirmed on Wednesday in Bitcoin block 964,199. It spent a 10,000-satoshi output protected by the QSB system.
MARA Pool mined the block after receiving the transaction through its Slipstream service.
How the Quantum-Safe Bitcoin System Works
Levy’s approach combines hash-based one-time signatures with computational methods designed to connect authorization directly to a specific Bitcoin transaction.
The goal is to protect Bitcoin transactions even in a future scenario where sufficiently powerful quantum computers are capable of breaking the elliptic-curve cryptography currently used by Bitcoin.
The experiment is significant because it demonstrates that a form of quantum-resistant Bitcoin spending may be possible under the network’s existing consensus rules.
In other words, this particular approach did not require a Bitcoin hard fork or major protocol change.
The mainnet test builds on Levy’s earlier proposal published in April and moves the idea from theoretical research to an actual onchain demonstration.
SEC Crypto Custody Rules Move to White House Review
Meanwhile, the US Securities and Exchange Commission (SEC) has taken another step toward rewriting its crypto custody framework.
The regulator has submitted its proposed custody changes to the White House for regulatory review.
The proposal reached the Office of Management and Budget’s regulatory review division on Aug. 25.
The document has not yet been released publicly. The OMB may request changes before sending it back to the SEC.
After that process, SEC commissioners could vote on whether to publish the proposal and open it for public comment.
New Rules Could Clarify How Advisers Hold Crypto
The SEC is considering amendments to existing regulations or potentially introducing new rules under the Investment Advisers Act and the Investment Company Act.
The objective is expected to include clearer guidance on how investment advisers and regulated funds can hold cryptocurrencies and other digital assets on behalf of clients.
The initiative forms part of a broader shift toward more formal crypto regulation under SEC Chair Paul Atkins.
This approach places greater emphasis on writing clear digital asset rules rather than relying mainly on enforcement actions.
US Crypto Regulation Remains in Focus
The SEC custody review arrives as the Trump administration continues advancing its wider digital asset agenda.
At the same time, the CLARITY market structure bill remains stalled in the Senate.
Lawmakers could revisit the legislation through a potential cloture vote in September, making US crypto regulation one of the most closely watched themes heading into the next phase of the market.
Taken together, today’s developments highlight how quickly the crypto industry is evolving across technology, payments and regulation. Stablecoin adoption, quantum-resistant Bitcoin technology and clearer institutional custody rules could all play an important role in shaping the next stage of digital asset adoption.
