Thank you to this week's sponsor Trail of Bits

Trail of Bits shared their review of this year's IACR Crypto Conference on the Trail of Bits blog. They highlighted some of the major themes of the conference, including the importance of getting basic cryptographic primitives right and the ascendance of cryptographic tools for privacy-preserving computation such as Zero-knowledge proofs, secure multiparty computation, and secure messaging systems.

For more on their thoughts from the conference and what they see on the horizon in their industry, check out the blog post here: https://blog.trailofbits.com/2019/09/11/crypto-2019-takeaways/
