United States Rep. Byron Donalds reported buying between $1,001 and $15,000 worth of Bitcoin on January 8, 2026, with the trade disclosed on February 12 while the asset was trading below $70,000. The filing also lists partial sales of several traditional stocks in late January, adding to prior criticism over his trading activity in office. A watchdog group had previously alleged he and his spouse failed to timely report over 100 stock transactions worth up to about $1.6 million in 2022 and 2023, keeping his investment history under ongoing review.

Brave Researchers Detail Structural Risks in zkLogin Zero-Knowledge Authorization on Sui
In a newly published paper and blog post, Brave security researcher Sofía Celi and colleagues analyze the zkLogin authorization system used in the Sui blockchain ecosystem, warning that its security, privacy, and trust properties rely on assumptions not enforced by the protocol. They describe three main vulnerability classes involving JWT parsing, weak bindings between authentication and authorization, and dependence on centralized identity and proving services. The team says these issues arise from architectural design choices and recommends stricter token validation, stronger issuer and user bindings, and improved consent when forwarding tokens to external services.
