April 23rd — Per Decrypt, OpenAI CEO Sam Altman pushed back against recent warnings about rival Anthropic’s powerful new Claude Mythos model, suggesting the company is using “fear marketing” to promote the product. Speaking on the *Core Memory* podcast hosted by tech journalist Ashlee Vance, Altman argued the “fear-based marketing” tactic aims to keep AI in the hands of “a few.” He noted: “Legitimate security concerns exist, so some arguments for this hold weight. But if the goal is ‘we need to control AI, and only we can because we’re trustworthy,’ fear marketing is the most effective pitch.” Altman added that while AI safety concerns are valid, he likened the tactic to: “We’ve built a bomb that’s about to drop on your head, and we can sell you a $100 million bomb shelter to protect your stuff — but the catch is we handpicked you as the customer.” Balancing AI’s new capabilities with OpenAI’s belief that “technology should be accessible” is “not easy,” he said.

On April 23, Bloomberg Senior ETF Analyst Eric Balchunas noted that Bitcoin ETF inflows have returned to a "highlight moment." Currently, all rolling periods we track have flipped to net inflows—a scenario not seen in months.

That said, tens of billions more dollars in inflows are still needed to set a new all-time high for cumulative historical inflows ($62.8 billion).

April 23 — Ledger CTO Charles Guillemet noted in a blog post that post-quantum cryptography (PQC) is entering a critical phase. While the timeline for quantum computers capable of breaking current cryptographic systems remains uncertain, the industry widely agrees a shift to PQC is inevitable. The traditional sector has a clear roadmap, led by the U.S. National Institute of Standards and Technology (NIST): phasing out vulnerable legacy algorithms by 2030, with full disablement by 2035. Large enterprises and government agencies are accelerating preparations to complete the transition by 2029. On the technical front, encryption and key exchange will transition to ML-KEM (formerly CRYSTALS-Kyber) to counter “decrypt-then-collect” quantum attacks. But in the blockchain ecosystem, the core focus is digital signatures. Current mainstream PQC signature schemes fall into two categories: lattice-based ML-DSA (formerly CRYSTALS-Dilithium) and hash-based SLH-DSA (formerly SPHINCS+). The
