FRI and Proximity Proofs (Part.1) w/ Dan Boneh

斯坦福大学教授 Dan Boneh 详细讲解 FRI 的密码学基础,包括线性码、IOP、RS-IOPP 与 SNARK 的转换及距离保持变换。

In this module (Part.1), Prof. Dan Boneh, applied cryptography and computer security professor at Stanford University, provides a comprehensive overview of FRI (Fast Reed-Solomon Interactive Oracle Proofs of Proximity) and its foundations in cryptography. Prof. Boneh begins with essential background on linear codes and Interactive Oracle Proofs (IOPs), then demonstrates how to compile a Polynomial-IOP into a SNARK using Reed-Solomon IOP of Proximity, before diving into distance preserving transformations with detailed examples of batch RS-IOPP and folding.

Why We Can't Build Perfectly Secure Multi-Party Applications (yet)
