Hey! I'm David, cofounder of zkSecurity and the author of the Real-World Cryptography book. I was previously a crypto architect at O(1) Labs (working on the Mina cryptocurrency), before that I was the security lead for Diem (formerly Libra) at Novi (Facebook), and a security consultant for the Cryptography Services of NCC Group. This is my blog about cryptography and security and other related topics that I find interesting.

How does PLONK work? Part 10: The Kate polynomial commitment scheme posted August 2021

In this tenth video, I explain how the Kate polynomial commitment scheme works. For more information about it, check this other blogpost I wrote.

Part 11 is here. Check the full series here.

Well done! You've reached the end of my post. Now you can leave a comment or read something else.
