‘Q-Day’ may arrive by 2030, putting 6.9 million bitcoin at risk

Warnings are growing that so-called “Q-Day,” when quantum computers can neutralise Bitcoin’s core cryptography, could come sooner than expected. Some researchers say real attacks could become possible around 2030, potentially endangering about 6.9 million bitcoin whose public keys are exposed. Project Eleven cited hardware-based experiments and said the main risk is whether migration to quantum-resistant cryptography can be completed before attacks become feasible.

Crypto Hot Issue: Crypto regulation stalls as South Korea shows distinct love for altcoins

South Korean brokerages are accelerating their push into digital assets, while the financial sector says regulatory gaps are holding back market entry despite infrastructure being largely ready. An analysis said South Korea accounts for about 30 percent of global cryptocurrency trading volume, with investors heavily focused on altcoins rather than bitcoin. In the United States, delays to the CLARITY Act have added uncertainty, while XRP posted weekly gains and inflows into spot ETFs rose.

Quantum computers still not a practical threat to AES-128 symmetric encryption

Even if quantum computing advances, symmetric-key encryption such as AES-128 is not a realistic target for attacks, a claim said. Cryptography engineer Filippo Valsorda, who maintains the Go programming language’s cryptography standard library, said quantum threats should distinguish between public-key and symmetric-key cryptography. He said Shor’s algorithm threatens asymmetric systems such as RSA and ECDSA, while Grover-based attacks on AES-128 remain extremely costly. He also urged focusing resources on replacing Shor-vulnerable public-key cryptography.
