⚙️ EIP-8288: Significant Gas Reduction for Post-Quantum Signatures & STARKs
Vitalik Buterin and Thomas Coratger have proposed EIP-8288 (Core Standards Track) to address the excessively high on-chain costs of post-quantum signatures and STARK proofs. Instead of being attached directly to transactions, the proofs will be aggregated by nodes into a single recursive STARK proof right within the mempool.
This solution could reduce gas costs from millions down to just a few tens of thousands, allowing Ethereum to support new cryptographic algorithms without requiring additional precompiles. Vitalik expects EIP-8288 to be integrated into the I-Star hard fork (following Hegota), marking a major milestone in the Lean Ethereum roadmap.

Warning: The latest iPhone can be controlled with just a PDF file - Don't open unknown PDFs: #AI is making the latest iPhones more vulnerable than ever
On October 16, 2026, at the Hexacon conference (Paris), Calif (Thai Duong & Bruce Dang) gave a live demo:
An untethered jailbreak on the iPhone 18 Pro running iOS 27.0.1: root privileges persist after rebooting.
A 1-click attack via a malicious PDF file in Signal and iMessage: simply opening the file allows code execution on the device.
This is not an attack via Gmail. Full technical details have not yet been fully disclosed.
Why is it dangerous?
iMessage/Signal are extremely popular. A PDF file from an acquaintance or a compromised account is enough to pose a risk.
Apple's security remains strong, but the gap with real-world attacks is narrowing, especially as AI helps discover vulnerabilities faster.
What to do immediately:
Update iOS to the latest version.
Do not open unknown PDFs (even from acquaintances) directly on your phone.
Consider enabling Lockdown Mode if you belong to a high-risk group.
Please share this with your loved ones. Being cautious with attachments is more critical now than ever.
