BSC Releases Post-Quantum Cryptography Migration Report: Transaction Signatures Have Been Upgraded to ML-DSA-44, TPS Decrease Approximately 40%-50%
BNB Chain Post-Quantum Migration Update (May 19)
On May 14, BNB Chain released its *BSC Post-Quantum Cryptography Migration Report*, as announced publicly on May 19. The report confirms that the project has successfully completed post-quantum cryptography (PQC) migration testing for two critical BSC layers: transaction signatures and the consensus layer. The migration leverages two NIST-standardized quantum-resistant solutions: the ML-DSA-44 (Dilithium) signature algorithm and the pqSTARK aggregation scheme.
Per the document, BSC has upgraded its cryptographic systems: transaction signatures now use ML-DSA-44 in place of ECDSA, and consensus voting aggregation has shifted from BLS12-381 to pqSTARK. This change is designed to mitigate the long-term threat quantum computing poses to the elliptic curve cryptography systems widely used in today’s blockchains.
However, the adoption of post-quantum signatures has significantly increased on-chain data volume, with tangible tradeoffs:

Ministry of Foreign Affairs: China and the United States Agree to Conduct Government-to-Government Dialogue on Artificial Intelligence
May 19 — Guo Jiakun, spokesperson for China’s Ministry of Foreign Affairs, hosted a regularly scheduled press briefing Wednesday. A reporter asked: Reports indicate that during their bilateral meeting, the leaders of China and the United States discussed approaches to regulating artificial intelligence and committed to holding dialogue and cooperating on the technology. What is China’s response to this?
Guo Jiakun stated: As two world leaders in artificial intelligence development, China and the U.S. should work together to advance the responsible development and governance of AI, ensuring the technology serves the progress of human civilization and the common well-being of the global community. “During President Trump’s visit to China, the two leaders had a constructive exchange about artificial intelligence and agreed to launch a government-to-government dialogue on AI,” Guo said.

US Crypto Regulation Shifts: From SEC Enforcement to Congressional Legislation, with Stablecoins at the Core
May 19 — A new industry analysis finds the U.S. is gradually shifting its approach to cryptocurrency, moving from "enforcement crackdowns" to establishing a formal regulatory framework. Over the past several years, the SEC has primarily overseen the crypto space through lawsuits and enforcement actions, but the lack of unified rules has left the market stuck in long-term legal uncertainty.
Right now, U.S. Congress is ramping up efforts to pass digital asset legislation, aiming to clarify which tokens qualify as securities versus commodities and assign clear regulatory oversight to the right agencies. The analysis notes this signals Washington is no longer debating whether to allow the crypto industry to exist — instead, it’s focusing on how to regulate it and capitalize on its potential benefits.
Stablecoins are a major driver behind this policy shift. Since U.S. dollar-pegged stablecoins tie directly to U.S. Treasuries, the domestic payment system, and the dollar’s global standing,

Republican Lawmaker Proposes Adding 'Permanent Ban on CBDC' Provision to '21st Century Housing Development Act'
May 19 — U.S. Republican lawmakers are pushing to add a "Permanent Ban on Central Bank Digital Currency (CBDC)" provision to the "21st Century ROAD to Housing Act." The U.S. House of Representatives is expected to vote on the measure this week.
Republicans have long opposed the Federal Reserve rolling out a retail digital dollar, contending that a CBDC would expand government surveillance of financial transactions, erode individual privacy, and jeopardize the existing banking system’s structure.

An Indian Doctor Falls Victim to Crypto Investment Scam, Loses Approximately $1.5 Million, Police Have Registered a Case for Investigation
May 19: A prominent private doctor in Guntur, India, lost roughly 1.3 billion rupees (about $1.5 million) in a cryptocurrency investment scam, per a *Times of India* report. Local police have opened an investigation following the doctor’s complaint, tracing the flow of funds and the online criminal gang linked to the fraud.
According to the report, scammers lured victims with high cryptocurrency investment returns via an online platform, first using fake profit data to gain trust. The doctor kept adding more money into the scheme and even convinced family and friends to invest alongside him.
When he tried to withdraw his funds, the platform began delaying or outright rejecting requests for various excuses. Though his account still displayed large "profits," none of the money was accessible—and the doctor finally realized he’d been scammed.
Police suspect the case involves an organized cross-border fraud ring. They are currently probing related bank accounts, digital wallets, a
