Ledger CTO Charles Guillemet said quantum computers powerful enough to break Elliptic Curve Cryptography could allow attackers to derive private keys from exposed public keys across major blockchains. He noted that Bitcoin public keys are revealed when coins are spent and were directly embedded in early pay-to-public-key outputs, leaving about 7 million BTC, including roughly 1 million attributed to Satoshi Nakamoto, theoretically vulnerable in an advanced quantum scenario. Guillemet said hardware signers are now the preferred way to secure cryptocurrencies because keys remain offline and signatures are generated inside a Secure Element, and Ledger is running post-quantum cryptography experiments in Secure Elements using software-only implementations despite significant RAM and compute constraints. He added that post-quantum cryptography offers quantum-resistant signature schemes in hash-based and lattice-based families, but stressed that secure implementation in signers is complex, while Ethereum cofounder Vitalik Buterin has separately outlined a roadmap to protect the Ethereum network from future quantum threats.

U.S. authorities froze over $580 million in cryptocurrency tied to fraud cases, the DC Scam Center Strike Force said. The frozen funds are linked to Southeast Asia-based "pig butchering" networks. Americans lose nearly $10 billion annually to such schemes, the Strike Force added.

The U.S. Securities and Exchange Commission and Japan's Financial Services Agency met in Tokyo during their Spring Regulatory Dialogue to discuss developments in crypto and digital assets, the two authorities said. The meeting explored opportunities for closer coordination on digital asset regulation.

The White House set a March 1 deadline to resolve the stablecoin rewards dispute and advance the Clarity Act. The timeline focuses policy decisions on stablecoin incentives and related legislative progress in the United States.

The U.S. Attorney's Office in Washington, D.C. announced its newly created Scam Center Strike Force has frozen or seized more than $580 million in crypto assets allegedly tied to pig butchering fraud networks operating in Myanmar, Cambodia and Laos. The schemes are accused of using social engineering tactics to persuade victims to purchase cryptocurrencies and transfer funds into fraudulent investment platforms.

Barclays, the British banking group with $2 trillion in assets, said it is reviewing blockchain technology applications, including stablecoins and tokenized deposits. The bank is evaluating how such solutions could support instant settlement and programmable money features within its product offerings.

A US strike force froze and seized over $580 million in cryptocurrency linked to Chinese crime networks. The operation targeted digital assets and combined asset freezes with seizures.

Barclays, which manages approximately $2 trillion in assets, is evaluating blockchain technology applications, including stablecoins and tokenized deposits. The bank's exploration covers blockchain-based solutions that may incorporate these digital instruments as part of its broader technology strategy.
