The cryptography protecting most blockchain transactions is getting easier to break. That does not mean quantum computers are a threat yet. It means the gap between today’s quantum capability and the defenses securing blockchain signatures is getting smaller. This new technical piece from Circle explores: → What is the gap between quantum attacks and blockchain defenses? → Why the threshold for breaking ECDSA keeps falling → Why wallet and chain infrastructure will need to change → How Circle is preparing for post-quantum signatures

Post-Quantum Cryptography isn't just another security upgrade. 🔒 Organizations that build crypto-agility into their infrastructure now will be better positioned to adopt new cryptographic standards as they evolve. HPE’s Andrew Wheeler explains.

Post-quantum cryptography is becoming an increasingly important area of research across the industry. Our latest report explores what a post-quantum migration path for BSC could look like, including: • ML-DSA-44 transaction signatures • pqSTARK aggregation • Throughput and block propagation trade-offs One important takeaway: The biggest challenge wasn’t consensus. It was the increase in transaction and block sizes once quantum-resistant signatures were introduced. Full report 👇

The first known cryptography is roughly 4,000 years old. Around 1900 BCE a scribe carved hieroglyphs in the tomb of an Egyptian nobleman named Khnumhotep II. In a few places he swapped standard symbols for unusual ones. Scholars don't think this was real secret-keeping. More likely it was for dignity, mystery, or to impress educated visitors. It is the oldest known instance of the technique that would later become cryptography.

Zakura is aggressively optimizing Zcash's cryptography for full nodes, miners and wallets. Each day, we're sharing a new optimization or development that either Valargroup or Tachyon has contributed. Here's our first one:

AI proliferation has not demonstrably caused real side-channel cryptography attacks. Its now so cheap to get way more timing samples of sensitive operations on all devices, and to analyze it better. Curious situation
