Abstract

Recent work by Bootle et al (https://eprint.iacr.org/2016/263) dramatically improved the size of zero-knowledge arguments based on discrete logarithms, from a square root to a logarithmic size. In just 5 minutes, I will explain zero-knowledge arguments and the main idea behind the performance boost. For real-world applications, such as gas-simulations or verifying hashes, this leads to proofs of under 7kB.
