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.

Donnelly also highlights broader concerns around self-custody risks, the emergence of stablecoin-native payment rails, and the impact of political timelines on how quickly a comprehensive regulatory framework is finalized.
