Ethereum Now Lets You Pay for AI Without Revealing Who You Are
The Ethereum Foundation has put zkAPI live on Ethereum's main network, a system that lets people pay for AI services without tying their identity to what they ask, according to the Ethereum Foundation's announcement. “Prompts are personal. People ask AI models about their health, their finances, their doubts. Under the current model, using AI means handing a running transcript of your thinking to whoever holds the billing relationship,” the Ethereum Foundation argued. Myriad: Where does Ethereum...

A Clever RSA Attack Fooled a Hardware Vault—Here's What It Means for Crypto
Researchers at UC San Diego and France's Institute for Research in Computer Science impersonated a hardware security module—a tamper-resistant device that stores private keys and signs on request—without ever pulling the key out of it. They detailed the attack in a paper submitted to the IACR Cryptology ePrint Archive on September 20. But don’t panic, crypto holders. This is not a Bitcoin or Ethereum break. Bitcoin uses an elliptic curve digital signature algorithm, or ECDSA. (Its curve also sup...

Months After the $292M Kelp Hack, Chainlink Lets Institutions Add Their Own Bridge Checks
Chainlink today launched CCIP 2.0, the newest version of its cross-chain plumbing—the software layer banks and crypto projects increasingly use to move tokenized money, like stablecoins, wrapped Bitcoin, and tokenized funds, between blockchains without building a bridge from scratch. That plumbing exists because blockchains don't talk to each other. Ethereum has no idea what's happening on Solana. So when a token moves from one chain to another, something has to confirm the money really left one...
