BITE - Bitcoin Lightweight Client Privacy Using Trusted Execution

Explore a conference talk from USENIX Security '19 that introduces BITE (Bitcoin Lightweight Client Privacy using Trusted Execution), a novel approach to enhance privacy for Bitcoin lightweight clients. Learn how BITE leverages SGX enclaves on full nodes to serve privacy-preserving requests from resource-constrained devices like mobile phones. Discover the challenges of maintaining user privacy in blockchain systems and how BITE integrates private information retrieval and side-channel protection techniques to address these issues. Understand the benefits of BITE in providing improved privacy protection for lightweight clients without compromising the performance of assisting full nodes. Gain insights into the intersection of blockchain technology, privacy concerns, and trusted execution environments in this 21-minute presentation by Sinisa Matetic from ETH Zurich.
