A security lapse at Indian certificate authority eMudhra has sent Ethereum developers scrambling. The blunder left certain configurations of the Teku and Besu clients vulnerable to forged certificates, potentially allowing attackers to impersonate trusted nodes. Fixes are already rolling out, and importantly, default mainnet setups were not exposed — but it's a sharp reminder of how much the blockchain ecosystem depends on traditional internet infrastructure it doesn't control.
Meanwhile, Google is moving fast in the AI race. Just two weeks after launching Gemini four Argon, the company has unveiled Gemini four Carbon — a stronger-performing model it's selling at the same price, at least for now. DeepMind's chief AI architect says Carbon shows particular strength in cybersecurity and long-running tasks. Whether the pricing holds is an open question, but the pace of iteration is striking even by recent standards.
And on a quieter but significant note, arXiv — the preprint server that underpins scientific research worldwide — is migrating its database to cloud storage. It's a behind-the-scenes infrastructure move, but arXiv hosts millions of papers across physics, mathematics, and computer science, making its reliability a matter of genuine public interest.
